I downloaded the zbar library and cloned the opencv-zbar repo in my home directory. Then I ran the following command $cmake . which gave my the error
-- Could NOT find ZBAR (missing: ZBAR_LIBRARIES ZBAR_INCLUDE_DIR)
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
ZBAR_LIBRARIES
linked by target "zbar_opencv" in directory /home/surabhi/opencv-zbar
-- Configuring incomplete, errors occurred!
See also "/home/surabhi/opencv-zbar/CMakeFiles/CMakeOutput.log".
I then made two changes in my CMakeCache.txt as follows
//Path to a file.
ZBAR_INCLUDE_DIR:PATH=/usr/include/zbar
//Path to a library.
ZBAR_LIBRARIES:FILEPATH=/usr/lib/libzbar.so
because the were set to NOTFOUND.
It then gave me no errors
-- Found ZBAR: /usr/lib/libzbar.so
-- Configuring done
-- Generating done
-- Build files have been written to: /home/surabhi/opencv-zbar
But when I run make
It gives the error:
fatal error: zbar.h: No such file or directory
#include <zbar.h>
^
compilation terminated.
I don't understand why I get this error as It says Found ZBAR when I run cmake.
Thanks in advance
You need to do actually use the include dirs somewhere in your CMakeLists.txt so CMake knows that you actually want to use these include paths.
Examples:
include_directories(${ZBAR_INCLUDE_DIR})
Or the more modern, recommended way:
target_include_directories(zbar_opencv PRIVATE ${ZBAR_INCLUDE_DIR})

Setting up swift-corelibs-xctest for Swift - Windows 10. When file CMakeLists.txt is called find_package is ran to look for FoundationConfig.cmake file
if(NOT CMAKE_SYSTEM_NAME STREQUAL Darwin)
find_package(dispatch CONFIG REQUIRED)
find_package(Foundation CONFIG REQUIRED)
endif()
FoundationConfig.cmake is found but error "include could not find load file: #Foundation_EXPORTS_FILE#"
I'm pretty sure this is due to fact that Foundation file is in a different directory. I only need clarification as to what # Foundation_EXPORTS_FILE# means. I have been unable to find any reference to _EXPORTS_FILE.
Believe I found part of what I was lookin for here.
https://gitlab.kitware.com/cmake/community/-/wikis/doc/cmake/ExportInterface
The other half of the problem was found here -
default search paths for CMake include() vs. find_package()
"include(#Foundation_EXPORTS_FILE#)" Was in reference to the two config files, which are not in the same location, also include() searches for files in CMAKE_MODULE_PATH --- message("Path- ${CMAKE_MODULE_PATH}")

Unable to find shared_ptr, try enabling CXX11 option if you expect C++11 to

even if i set CXX11 ON, I would get the same error. What should I do?
Assuming I get this working, do I just run make install to get the libceres.a file?
Much help appreciated.
This is not a C++11 error, notice the error
CMake Error: Generator: execution of make failed. Make command was: "CMAKE_MAKE_PROGRAM" "cmTC_3feba/fast"
CMake is trying to determine the presence of various c++11 features by compiling several short program fragments, and is unable to do so, due to some Make related problems (do you have make installed? Xcore command line tools?) and it ends up concluding that c++11 is not available.
The thing to fix here is to see what is going on with Make on your system.
When I make a new framework with aggregate to generate universal framework , but a error present , as follow :
cp: build/Release-iphoneos/TEST.framework/: No such file or directory
fatal error: lipo: can't open input file: build/Release-iphoneos/TEST.framework/TEST (No such file or directory)
Command /bin/sh emitted errors but did not return a nonzero exit code to indicate failure
And here is a screenshot of the error:
This is a new target , I only want to test generate framework , but fail!
As the error message said, no TEST.framework can be found in the path <PROJECT_DIR>/build/Release-iphoneos/TEST.framework.
You need to check the script you use, or the blog post which you reference is out-date.
First you should build the target specified in xcodebuild command directly to see if it can build succeed.
Check what the actual build path is. If the path(build/) is not exist, you can try to specified the build path for xcodebuild, OBJROOT=${WRK_DIR} SYMROOT=${WRK_DIR}
I try to install a ROS indigo package jsk_recognition for chessboard detection and relative position, I have opencv-3.0.0-rc1 on Ubuntu 14.04. When I try to catkin_make the package I receive build errors, quit a lot, the full report is here, but it starts like:

the problem seams to be with the linemod class, which in the online opencv documentation exist but in my case the compiler does not recognise it. The linemod.h header file can't be find in any opencv folder only in:
./home/elod/catkin_ws/src/vision/jsk_recognition-master/jsk_pcl_ros/include/jsk_pcl_ros/linemod.h
./opt/ros/indigo/include/jsk_pcl_ros/linemod.h
./usr/include/pcl-1.7/pcl/recognition/linemod.h
Is this module missing somhow my OpenCV installation or why cant find it in the cv namespace?
In my old Opencv 2.4.11 (uninstalled) seams to be included this module, but I migrated all my stuff to 3.0.0.
Any ideas how to solve it?
UPDATE
A very important observation is that the above mentioned pkg is for Opencv2.4 and I'm using 3.0! Some stuff was moved or removed from the new version like cvSnakeImage, which also appears in this pkg.
An other question would be: how to replace the cvSnakeImage or with what can be replaced?
Did you build from scratch (clean build directory) ?
You could try adding cv:: namespace into *.hpp
-<linemod::Match>
+<cv::linemod::Match>
And/or try adding "#include <opencv2/rgbd/linemod.hpp>" into the same file.
I downloaded the source of LuaJIT and compiled it with msvc120.dll (VS 2013 x64). When I run it from the command line I have no problems executing some basic lua. Now the LuaJIT installation guide mentions moving luajit.exe and lua51.dll into their own folder. From there it says to create a lua folder and under that a jit folder with the contents of src/jit moved underneath the newly created jit folder.
From my understanding my folder should look like and contain:
luajit.exe
lua51.dll
/lua
/jit
bc.lua
[rest of jit files]
vmdef.lua
Is this correct or am I missing files?
Now after I built my luajit I tried to wire it up into my luarocks to act as my interpreter using
install.bat /LUA C:\LuaJIT\2.0.3\[folder with above content]
However this cannot find the header files. I then copied over what are the header files into the folder above and that wires it up, but I can never actually get anything to compile when pointed over to LuaJIT. Edit: The error I get is the following,
C:\LuaJIT\2.0.3\bin\lua51.dll : fatal error LNK1107: invalid or corrupt file: cannot read at 0x2D0
Error: Failed installing dependency: https://rocks.moonscript.org/luafilesystem-1.6.2-2.src.rock - Build error: Failed compiling module lfs.dll
Is the correct way to handle this to simply point to my lua binaries and from there leverage LuaJIT to run my files or am I doing something wrong with wiring up LuaJIT and luarocks? The former seems to work for the most part, since I only ran into one library compilation issue, lua-cjson.
I've run on exactly the same problem, but they've found a solution right here:
https://github.com/keplerproject/luafilesystem/issues/22
I knew that for "linking DLLs statically" there is a so-called "export" .lib file, which is passed to the linker (and not the DLL itself).
So, for example, when compiling, LuaRocks was doing this:
cl /nologo /MD /O2 -c -Fosrc/mime.obj -ID:/LuaJIT-2.0.4/include/ src/mime.c -DLUA_COMPAT_APIINTCASTS -DLUASOCKET_DEBUG -DNDEBUG -DLUASOCKET_API=__declspec(dllexport) -DMIME_API=__declspec(dllexport) mime.c
link -dll -def:core.def -out:mime/core.dll D:/LuaJIT-2.0.4/bin/lua51.dll src/mime.obj
My LuaJIT was compiled from source in D:\LuaJIT-2.0.4\src, but I made two folders myself: D:\LuaJIT-2.0.4\include with all *.h files copied from src and D:\LuaJIT-2.0.4\bin with luajit.exe, lua51.dll, and then later lua51.exp and lua51.lib. Still same error, but this was the right track.
Fix
Now, check where your LuaRocks configs are:
luarocks.bat help
Scroll down to a section like:
CONFIGURATION
Lua version: 5.1
Configuration files:
System: D:/luarocks/config-5.1.lua (ok)
User : (... snip ...)
Edit the System configuration file, specifically see the part:
variables = {
MSVCRT = 'VCRUNTIME140',
LUALIB = 'lua51.dll'
}
Here! LUALIB should be the .lib file. If your export lib is alongside the DLL, you just need to change to:
variables = {
MSVCRT = 'VCRUNTIME140',
LUALIB = 'lua51.lib' -- here!
}
Verification
And now:
luarocks.bat install luasocket
(...)
link -dll -def:core.def -out:socket/core.dll D:/LuaJIT-2.0.4/bin/lua51.lib src/luasocket.obj (...)
(...)
luasocket 3.0rc1-2 is now built and installed in D:\luarocks\systree (license: MIT)
Note the first argument passed to the linker.
