I have set environment variables CC, LINK, AR. When linking static libraries, it hits many errors like:
XXX.lib(YYY.obj) : error LNK2001: unresolved external symbol ___cs_tb_cqAX5_1FNfXC_1nA5FM_main_AAAA_BBBB_lib_CCC_DDDD_c
There is no problem for shared libraries. Is there some special setting for static library with Squish Coco? It works correctly without Squish Coco.
I am using Squish Coco 4.3.3.
I have tried to exclude relative source files by -cs-exclude-file-regex=(aa|bb|cc).*
But it could not read correctly after |, it seems Scons' issue?
There is GENERATE_COVERAGESCANNER_LIBRARY in link.cspro, lib.cspro, cl.cspro, ar.cspro. Does it matter? How should I set them?
This is from Squish Coco document:
GENERATE_COVERAGESCANNER_LIBRARY=⟨YES/NO⟩:
If set, the CoverageScanner library is generated during the linking operation. This should be disabled when generating static libraries.
My issue is resolved by following steps:
search for link.cspro in the %SQUISHCOCO% directory (there are more than one).
edit it and replace the line:
LIBRARY_PATH_OPTION=/LIBPATH:;-LIBPATH:
through:
LIBRARY_PATH_OPTION=/LIBPATH:;-LIBPATH:;/libpath:;-libpath:
Then resume the build.
The reason is in the LINKFLAGS "/libpath:" is used, However Froglogic Squish Coco handle only "/LIBPATH:".

I'm using the nativescript-google-maps-utils plugin in a NativeScript JavaScript project to access GoogleMapsUtils functions (GMSGeometryDistance, GMSGeometryInterpolate, and GMSGeometryHeading) so that I can traverse a polyline. The Android equivalents work fine on Android devices, and the iOS functions listed work on an iOS simulator, but on an iOS device I get the exception,
ReferenceError: Metadata for "GoogleMaps.GMSGeometryDistance" found but symbol not available at runtime.
I've been chasing this for the better part of a day and still don't have any leads; I'd welcome any insight.
[edit]
It's worth mentioning I've done the usual removal of the platforms, hooks, and node-modules folders and rebuilt, with no change in the error.
Here's the first line of code that triggers the error:
let lineDistance = GMSGeometryDistance(latlngs[i], latlngs[i + 1]);
[edit 2]
Still chasing this... I gather from this issue that I need to create a file with a list of exported symbols, and this issue kind of suggests how that could be done, but I'm not understanding how that applies to this situation.
That is, the question at hand now is how can I determine the symbols from the iOS GoogleMapsUtils static library? This is becoming more of an iOS and Xcode question that NativeScript or JavaScript.
[edit 3]
Sigh... I did get this working using the answer I provided below, but now that same approach is no longer working. No idea why :-(
[edit 4]
I re-reviewed the links I referenced above and included the STRIPFLAGS option and now the code works properly. I revised the answer to include this, and to edit build.xcconfig rather than the project file.
After another day's investigation I was able to get this working. Here's what it took.
Navigate to /platforms/iOS/Pods/GoogleMaps/Maps/Frameworks/GoogleMaps.framework/
Run nm --defined-only GoogleMaps | grep " T " | cut -f 3 -d' ' | egrep -v '^$|GoogleMaps'
Notice the names of the symbols. In my case each one I needed was the function name prefixed with an underscore
Create the file exportedSymbols.txt in /app/App_Resources/iOS
Add the symbols to the file. In my case the contents is:
_GMSGeometryDistance
_GMSGeometryHeading
_GMSGeometryInterpolate
Edit the file app/App_Resources/iOS/build.xcconfig and add these two lines
STRIPFLAGS=$(inherited) -s {PROJECT_DIR}/../../app/App_Resources/iOS/exportedSymbols.txt
EXPORTED_SYMBOLS_FILE = ${PROJECT_DIR}/../../app/App_Resources/iOS/exportedSymbols.txt
So far this is working in my tests on both iOS simulators and devices.
I am trying to produce an Ada library for iOS.
However, it is necessary to perform the Ada elaboration manually.
I know that the compiler can produce an init symbol, that can be later imported and used. However, with the following GPR definition, it is not produced (the nm command does not list it). The naming is supposed to be <libname>init with <libname> corresponding to the value defined in the GPR directive Library_Name
The GPR is defined in the following fashion (this one is windows/style -see DLL references-, but the problems also applies when producing for iOS on a Mac):
project adalib is
for Languages use ("Ada");
for Source_Dirs use (project'Project_Dir & "./src");
for Library_Kind use "static"; --"static" on iOS will produce a .a file
for Library_Name use project'Name; -- will produce "libadalib.a"
for Library_Dir use project'Project_Dir & "./lib";
for Library_Src_Dir use project'Project_Dir & "./includes";
-- define your favorite compiler, builder, binder, linker options
end adalib;
I'm missing it : how to produce that symbol ?
I found the solution.
My GPR was missing this simple directive:
for Library_Interface use ("mypackage"); -- put whatever packages you want to expose, without .adb/.ads since we're talking about packages
With the above directive, I can find the adalibinit symbol via nm command.
When I import it in my ada code, I can also use it, see :
package body mypackage is
procedure Init_My_Lib
is
-- I want to call elaboration;
pragma import (C, ada_elaboration, "adalibinit");
begin
ada_elaboration;
-- further code
end Init_My_Lib;
-- rest of package
So, the full GPR should be:
project adalib is
for Languages use ("Ada");
for Source_Dirs use (project'Project_Dir & "./src");
for Library_Kind use "static"; -- will produce a .a file
for Library_Name use project'Name; -- will produce "libadalib.a"
for Library_Interface use ("mypackage"); -- <=== THIS IS HERE
for Library_Dir use project'Project_Dir & "./lib";
for Library_Src_Dir use project'Project_Dir & "./includes";
-- define your favorite compiler, builder, binder, linker options
end adalib;
I downloaded the sources of opencv-2.4.5 and I followed the tutorial (on the opencv site for windows) about the installing my own libraries everything. Ok. I created the opencv.sln file with cmake then I opened it with visual studio 2010 professional and I click the build solution but just 9 succeeded. Most of the 200 failed and most of the errors about tbbd.lib not found and opencv_core245d.lib not found with LNK1104 error. I'm trying to solve it for how many days. I've tried to show the ways of files... Anyone can help please? This is about my dissertation. (Build with No Common Language Support)

I spent a good 15 hours or so to get the homework finished using OpenCV. 14.5 of those hours were spent just getting it setup properly. I ran through about 7 tutorial videos, several set up guides, and read hundreds of posts containing resolutions to the same erros I was getting.So I understand that simply installing OpenCV is not a trivial task and there are several steps to do this. So here is a straightforward tutorial for setting it up if you want to use openCV.
It is important to understand how things work as far as linking goes. There are three types of files, your headers that you include, the .dlls that contain the functions, and the libraries that contain instructions for how to call the functions in the .dlls. So here, rather than add just the .dlls as dependencies in the input linker, we are going to add the lib files. We will then create a System Environment variable that will tell the machine where to look for the .dll files when their corresponding library files are referenced. We will be creating a Property Sheet so that when we create a new project, we can simply add the settings to our project by clicking "Add Existing Property Sheet" instead of adding a new one. This way, we never have to go through this again.
FOLLOW THESE STEPS EXACTLY AND MAKE SURE VISUAL STUDIO IS CLOSED BEFORE CONTINUING
NOTE: When text is given in quotes with instructions to copy said text, do not include the quotes.
First of all, the easy part - download OpenCV 2.4.5 from their website. http://opencv.org/ and click OpenCV for Windows. It will download OpenCV 2.4.5.exe.
Install OpenCV
When the download finishes, double click OpenCV-2.4.5.exe to run it.
When asked where to extract the files, type ino the text box: "C:\"
C:\opencv should have been created upon completion. Navigate there to make sure.
Setup Environment Variables
WINDOWS 8 USERS:
- Right click the bottom left corner of your screen when the start icon pops up.
- Click "Command Prompt (Admin)"
- Type "SETX -m OPENCV_DIR C:\opencv\build" and press enter to set the opencv build directory as a System Environment Variable. Wait for the console to give you confirmation that it is set.
- Right click the bottom left corner of your screen when the "Start" icon pops up. Click System -> Advanced System Settings -> Environment Variables
- In the "System Variables" list box, under the "Variable" collumn, find "Path".
- Highlight the "Path" row and click edit.
- Click in the "Variable Value" text box and hit the "end" key on your keyboard to scroll to the end of the line and add a semicolon.
- Type the following: "C:\opencv\build\x86\vc10\bin;C:\opencv\build\x86\vc10" and click "OK". This will add the openCV bin directory to the system path.
WINDOWS 7 USERS:
Follow the same steps. The only difference is how you get to the command prompt and the system settings. Google how to set up an environment variable on Windows 7 if needed.
Setup Visial Studio
NOTE: I highly recommend VS2012 Professional because of advanced syntax highlighting that makes life so much easier when programming C++. This version can be downloaded and installed for free from DreamSpark. Just make and account with your student ID. However, the steps for VS2010 and VS2012 are the same.
Open Visual Studio
Click "New Project" and under "C++" select "Win32 Console Application".
When the window opens click "Next", check "Empty Project", and click "Finish". It is very important that you start with an EMPTY PROJECT without a precompiled header.
Locate the "Property Manager." By default, it should be a tab that is sometimes hard to miss. Alternatively it can be accessed by clicking from the toolbar "View" -> "Property Manager".
Right Click "Debug | Win32" and select "Add New Project Property Sheet". Name it "OpenCVProps" and click "Add".
Right Click your new property sheet and select "Properties".
From the left column, go to "C/C++" -> "General" and in the listbox on the right, select "Additional Include Directories" and click "Edit".
Add the following THREE directories:
"$(OPENCV_DIR)\include"
"$(OPENCV_DIR)\include\opencv"
"$(OPENCV_DIR)\include\opencv2"
From the left column, go to "Linker" -> "General" and in the listbox on the right, select "Additional Library Directories" and click "Edit".
Add the following directory:
"$(OPENCV_DIR)\x86\vc10\lib"
From the left column, go to "Linker" -> "Input" and in the listbox on the right, select "Additional Dependenies" and click "Edit".
Add the following .lib files to the depedencies. You may do this by copying and pasting these into that edit box. I have purposely not included a bulletpoint to make it easy for you to copy paste these.
opencv_core245d.lib
opencv_imgproc245d.lib
opencv_highgui245d.lib
opencv_ml245d.lib
opencv_video245d.lib
opencv_features2d245d.lib
opencv_calib3d245d.lib
opencv_objdetect245d.lib
opencv_contrib245d.lib
opencv_legacy245d.lib
opencv_flann245d.lib
NOTE: If building for release, these steps are the same. However, when copying and pasting these files, remove the 'd' from the end of each of them. The 'd' denotes that it is a release library and links to a release .dll.
Congrats! The difficult part is almost done! Click "OK" to close the Window.
Creating and Building a Test Project
Head over to our Solution Explorer. This can be focused from the toolbar via "View" -> "Solution Explorer"
Right click "Source Files" and select "Add" -> "New Item".
Select "C++ File (.cpp)" and name the file "main.cpp". Click "Add".
Copy and paste the following program and press "F7" on your keyboard and watch the bottom left corner of your screen to see if you get a "Build Succeeded" message. If so, only one step left before you compile and run! If not, please retrace your steps, or comment below and maybe I can help.
#include <opencv\cv.h>
#include <opencv\highgui.h>
int main(int argc, char* argv)
{ // openCV .image object
cv::Mat inputImage;
//Create a Window
cv::namedWindow("window",1);
// Initialize our image.
inputImage = cv::imread("Lenna.png");
// Always check to make sure that image has data.
if(inputImage.empty())
{
std::cout << "Image Failed to Load.";
return -1;
}
else
{
// All is well, display me.
cv::imshow("window",inputImage);
// Wait for user to press a key to exit.
cvWaitKey(0);
}
return 0;
}
If the build succeeded, then all that is left is to add the image to your folder. The placement is very important. I have copied the directoy that I have placed mine in. Follow the same directory pattern.
"C:\Users\Josh\Documents\Visual Studio 2012\Projects\ConsoleApplication3\ConsoleApplication3\Lenna.png"
Now hit "Ctrl + F5" To build, compile, and run to observe your image in the window!!
*IF YOU HAVE A WEBCAM*
Copy and paste the following code to check if OpenCV is working without being required to add an image. This is useful because if the above code doesn't work, but this code does, then you know you put the image in the wrong folder.
#include
#include
int main(int argc, char* argv)
{ // openCV .image object
cv::Mat image;
//Create a Window
cv::namedWindow("window",1);
// Create the capture object.
cv::VideoCapture device;
// Open your webcam.
device.open(0);
while (1)
{
// Read data from your device and store it to the image frame.
device >> image;
// Always check to make sure that image has data.
if(image.empty())
{
std::cout<< "Image Failed to Load.";
return -1;
}
else
{
// All is well, display me.
cv::imshow("window",image);
// Wait for user to press a key to exit.
cvWaitKey(33);
}
}
return 0;
}
Happy Coding!! Let me know if something didn't work so I can fix it!
Quick Answer
I have managed to compile OpenCV with TBB support using the tutorial here.
Specs: Visual Studio 2012/ Win 7 (64 bit)/ OpenCV 2.4.5/ CUDA 5
I have downloaded the latest TBB zip and extracted it to C:/src/OpenCV/dep (as suggested in the tutorial linked above).
You have to use the following TBB settings in CMake (adapt depending on your file paths):
TBB_LIB_DIR :: C:/src/OpenCV/dep/tbb41_20130314oss/lib/intel64/vc11
TBB_INCLUDE_DIRS :: C:/src/OpenCV/dep/tbb41_20130314oss/include/
TBB_STDDEF_PATH :: C:/src/OpenCV/dep/tbb41_20130314oss/include/tbb/tbb_stddef.h
WITH_TBB :: checked
BUILD_TBB :: unchecked
More Information
Initially, I also wanted to install OpenCV with CUDA 5 support, but it seems that CUDA 5 is incompatible with VS2012. This is the error I got when compiling
OpenCV:
Building NVCC (Device) object modules/core/CMakeFiles/cuda_compile.dir/src/cuda/Debug/cuda_compile_generated_matrix_operations.cu.obj
nvcc : fatal error : nvcc cannot find a supported cl version. Only MSVC 9.0 and MSVC 10.0 are supported
The good news is that you are using VS2010, which can be used with CUDA, as suggested here.
VS2012 can be set up to create projects with CUDA, but there is currently no way (AFAIK) to compile OpenCV with CUDA support for VS2012 (read this for more info).
In conclusion, people that need CUDA support should compile and use OpenCV with VS2010.
Also, when compiling OpenCV, I got the following errors:
error C3859: virtual memory range for PCH exceeded; please recompile with a command line option of '-Zm118' or greater
fatal error C1076: compiler limit : internal heap limit reached; use /Zm to specify a higher limit
I used the instructions here to finally compile OpenCV. I created a Property Sheet which had /Zm130 as an additional option in Common Properties > C/C++ > Command Line and added it
to all of the generated OpenCV projects.
For your reference, I also attach the CMake configuration and CMakeCache.txt file that I've used (CUDA is disabled as I am using VS2012):
CMake configuration: http://pastebin.com/8rJZGZ3T
CMakeCache.txt: http://pastebin.com/A0q8YgJg
Hope this helps and please comment if you need me to elaborate on any step.
I installed again opencv-master, opencv-2.4.5 and opencv-2.4.7 both to my new laptop. OpenCV-2.4.7's imread function returned always null but C-cvImageLoad worked well and opencv-master's cvLoadImage didn't work cvImageLoad or I missed something. But TBB's dir must be .../bin/ia32 not intel64 my OS is 64-bit but VS201x 32-bit this was my error. And I've get stitching and gpu errors and visual studio is telling about the error and this is usually memory allocation limit error and I did same things like your said #dilgenter and now it's working well but just 2.4.5 well and the python_d.lib error can be occur this is not a problem at debug mode I've read about this from a lot of forum sites. I'll try to find why 2.4.7's imread returning null Mat element. But now I'm too busy and this is
I'm trying to integrate xlslib in my app. After compiling and installing lib, I have added this in my code. Then I got the error shown below:
format_t::format_t(CGlobalRecords& gRecords, const u16string& fmtstr) :
formatstr(fmtstr),
index(0),
m_usage_counter(0),
m_GlobalRecords(gRecords)
{
}
Errors:
format.cpp:125:52: Reference to 'u16string' is ambiguous
Out-of-line definition of 'format_t' does not match any declaration in
xlslib_core::format_t
while in format.h file, declaration as below
format_t(CGlobalRecords& gRecords, const u16string& fmtstr);
Can any one help to solve this issue?
Why didn't you post a bug report on the SourceForge page? In any case, the xlslib project has been updated and now offers the DHxlslibIOS library that you can incorporate as is into your project. You can download a zipped package here with the latest 2.4.0b1 source, or pull it from SVN. The framework is in the DHxls directory.
Am a beginner to OpenCV and have gone so far as to work out the hello world samples, inverting, color conversion(RGB->greyscale ) etc programs working.
However i am stuck at the Programs that use cvCanny, cvPyr and other such feature detectors.Would really be thankful if the tiny prblem was sorted out .
I get the Error: error C3861: 'cvPyrDown': identifier not found
error C3861: 'cvCanny': identifier not found
I've included the imgproc and features2d headers yet the problem persists.
What am I missing out ?
Do you have your "Additional input directories" property set correctly?
Mine, configured by cmake, looks like this:
C:/OpenCV-2.2.0/release
C:/OpenCV-2.2.0/include
C:/OpenCV-2.2.0/include/opencv
C:/OpenCV-2.2.0/modules/core/include
C:/OpenCV-2.2.0/modules/imgproc/include
C:/OpenCV-2.2.0/modules/features2d/include
C:/OpenCV-2.2.0/modules/gpu/include
C:/OpenCV-2.2.0/modules/calib3d/include
C:/OpenCV-2.2.0/modules/objdetect/include
C:/OpenCV-2.2.0/modules/video/include
C:/OpenCV-2.2.0/modules/highgui/include
C:/OpenCV-2.2.0/modules/ml/include
C:/OpenCV-2.2.0/modules/legacy/include
C:/OpenCV-2.2.0/modules/contrib/include
C:/OpenCV-2.2.0/modules/flann/include
Btw. CMake is a nice tool if you are dealing with libraries that contains many include files, line OpenCV.
You can also check two other things:
After compiling OpenCV2.2 from sources, did you built "INSTALL" project in the OpenCV VS solution?
If you are using c++ headers, you might prefer c++ version of those functions,
in the cv namespace:
cv::Canny(...)
That sounds like a link error rather than any problems with include. Are you sure you are linking with cv.lib?
You need to add the $(OPENCV_ROOT)/lib directory to the linker path so it knows where to search for the files.
From the description, I assume you're using Visual Studio? If so, you have two options for doing so.
Add it to this project under Project -> Properties -> Linker -> General -> Additional Library Directories.
Add it for all projects: Tools -> Options -> Projects and Solutions -> VC++ Directories -> Library files. And then add folders there.
