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}")
I've been trying to install Luadist, but an error with CMake always happens and in the end it doesn't install because of it.
This seems to be a common issue on Windows 10. I've followed the instructions from https://github.com/LuaDist/Repository/wiki/LuaDist%3A-Installation and https://github.com/LuaDist/Repository/wiki/Installation-of-System-Dependencies#microsoft-windows . I've tried uninstalling it and installing it again, but it didn't work. I tried installing Lua on the same drive as LuaDist, but it still doesn't work. I think the error might be because I also have LuaRocks installed, I don't know if they are compatible together.

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})

Now, according to the tutorial, I wrote a simple program. Problem is that, cmake gets some errors and seems that it is not able to find the library.
CMake Error at CMakeLists.txt:3 (find_package):
By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "OpenCV", but
CMake did not find one.
Could not find a package configuration file provided by "OpenCV" with any
of the following names:
OpenCVConfig.cmake
opencv-config.cmake
Add the installation prefix of "OpenCV" to CMAKE_PREFIX_PATH or set
"OpenCV_DIR" to a directory containing one of the above files. If "OpenCV"
provides a separate development package or SDK, be sure it has been
installed.
I don't know how to set CMAKE_PREFIX_PATH or OpenCV_DIR. How can I fix that?
The content of CMakeLists.txt is
cmake_minimum_required(VERSION 2.8)
project( DisplayImage )
find_package( OpenCV REQUIRED )
add_executable( DisplayImage DisplayImage.cpp )
target_link_libraries( DisplayImage ${OpenCV_LIBS} )
It depends whether you have OpenCVConfig.cmake script, which comes with your installation of OpenCV (that is, under install directory /share/apps/computer/opencv-3.2.0/built/).
If your installation of OpenCV lacks of OpenCVConfig.cmake script, you need to ship your project with script FindOpenCV.cmake (find and copy it from the net, almost any of them is suitable), and add directory with this script to CMAKE_MODULE_PATH variable:
list(APPEND CMAKE_MODULE_PATH <directory-with-find-script>)
Possible ways to hint CMake about your installation of OpenCV:
If you have OpenCVConfig.cmake script, set OpenCV_DIR variable to directory contained this script:
cmake -DOpenCV_DIR=/share/apps/computer/opencv-3.2.0/built/<...>
Set CMAKE_PREFIX_PATH variable to installation prefix of OpenCV:
cmake -DCMAKE_PREFIX_PATH=/share/apps/computer/opencv-3.2.0/built
This works both with OpenCVConfig.cmake and with FindOpenCV.cmake scripts. See also that question: Hinting Find<name>.cmake Files with a custom directory.
I have OpenCV 3.0.0 installed in /usr/local/opencv-3.0.0
I am trying to construct a CMakeLists file to build a library against this OpenCV 3.0.0. The CMakeLists.txt is as follows:
cmake_minimum_required(VERSION 2.8)
project(STT_People_Tracker)
cmake_policy(SET CMP0016 NEW)
# compilation mode setup
#set(CMAKE_BUILD_TYPE Release)
set(CMAKE_BUILD_TYPE Debug)
# set OpenCV directories - CHANGE DEPENDING ON SYSTEM
set(OpenCV_PATH "/usr/local/opencv-3.0.0")
set(OpenCV_INCLUDE_DIRS "${OpenCV_PATH}/include")
set(OpenCV_LIBS "${OpenCV_PATH}/lib/")
# set environment variables
set(SOURCES_PATH "${CMAKE_SOURCE_DIR}/Sources")
set(INCLUDES_PATH "${SOURCES_PATH}/include")
if(CMAKE_BUILD_TYPE MATCHES Debug)
set(OUTPUT_PATH "../Debug")
message(STATUS "Compiling in DEBUG mode")
elseif(CMAKE_BUILD_TYPE MATCHES Release)
set(OUTPUT_PATH "../Release")
message(STATUS "Compiling in RELEASE mode")
endif()
include_directories(${INCLUDES_PATH})
include_directories(${OpenCV_INCLUDE_DIRS})
# compilation of executables
message(STATUS "configuring executables...")
add_executable(${OUTPUT_PATH}/mainTest ${SOURCES_PATH}/mainTest.cpp)
# compilation of libraries
message(STATUS "configuring libraries...")
add_library(${OUTPUT_PATH}/background_substractor ${SOURCES_PATH}/background_substractor.cpp)
# set linker options
link_directories(${OpenCV_LIBS})
target_link_libraries(${OUTPUT_PATH}/mainTest opencv_core opencv_highgui)
target_link_libraries(${OUTPUT_PATH}/background_substractor opencv_core opencv_highgui)
message(STATUS "cmake configuration complete")
It is a fairly simple Cmake file, however, I have the following problems/doubts:
1.-How can I know I am using OpenCV 3, and not other versions of OpenCV present in the system?
2.- When compiling the file background_substractor, its associated header file can not be located, although I have checked the path and it is correctly assigned in the set(INCLUDES_PATH "${SOURCES_PATH}/include"):
/home/alberto/STT_People_Tracking/Sources/background_substractor.cpp:3:36: fatal error: background_substractor.h: No such file or directory
#include "background_substractor.h"
^
compilation terminated.
make[2]: *** [CMakeFiles/../Debug/background_substractor.dir/Sources/background_substractor.cpp.o] Error 1
make[1]: *** [CMakeFiles/../Debug/background_substractor.dir/all] Error 2
make: *** [all] Error 2
3.- Finally, and if I comment the header file, I have problems linking:
Linking CXX static library lib../Debug/background_substractor.a
/usr/bin/ar: lib../Debug/background_substractor.a: No such file or directory
make[2]: *** [lib../Debug/background_substractor.a] Error 1
make[1]: *** [CMakeFiles/../Debug/background_substractor.dir/all] Error 2
make: *** [all] Error 2
I have tried everything: Specifying the include files in the add_executable() and add_library() commands, I have checked paths and they are ok, etc etc.
Could anyone more experienced with CMake, give me a little hand?
Thank you very much in advance,
Alberto
How can I know I am using OpenCV 3, and not other versions of OpenCV present in the system?
Your project should check that.
But usually projects just use find_package command for fill variables related to 3d-party library. This command perform all needed checks. In your case it could be
find_package(OpenCV 3 REQUIRED)
call, which fills OpenCV_LIBS and OpenCV_INCLUDE_DIRS variables automatically. This command, by default, search OpenCV installation in default paths, but you can adjust searching algorithm by using parameters to cmake (so, you needn't to change CMakeLists.txt when you build the project on other machine). E.g., this way
cmake -DOpenCV_DIR=/usr/local/opencv-3.0.0 <source-dir>
you can specify precise installation path of OpenCV.
When compiling the file background_substractor, its associated header file can not be located...
Cannot suggest anything aside from checking file existence
/home/alberto/STT_People_Tracking/Sources/include/background_substractor.h
But this also can be a result of the 3d issue(see below).
Finally, and if I comment the header file, I have problems linking...
Your usage of CMake targets is incorrect. Unlike to make targets, which usually are files, CMake targets are simple names. By default, name of library/executable target determines filename of the library/executable file, produced by this target, but this can be changed. Directory, where resulted file will be located, can be adjusted using CMAKE_<TYPE>_OUTPUT_DIRECTORY variables, where <TYPE> can be ARCHIVE, LIBRARY or RUNTIME depending on target type.
Correct CMake script would be:
cmake_minimum_required(VERSION 2.8)
project(STT_People_Tracker)
cmake_policy(SET CMP0016 NEW)
# compilation mode setup
#set(CMAKE_BUILD_TYPE Release)
set(CMAKE_BUILD_TYPE Debug)
# set OpenCV directories using find_package.
find_package(OpenCV 3 REQUIRED)
# set environment variables
set(SOURCES_PATH "${CMAKE_SOURCE_DIR}/Sources")
set(INCLUDES_PATH "${SOURCES_PATH}/include")
if(CMAKE_BUILD_TYPE MATCHES Debug)
set(OUTPUT_PATH "${CMAKE_BINARY_DIR}/Debug") # Use absolute path
message(STATUS "Compiling in DEBUG mode")
elseif(CMAKE_BUILD_TYPE MATCHES Release)
set(OUTPUT_PATH "${CMAKE_BINARY_DIR}/Release")
message(STATUS "Compiling in RELEASE mode")
endif()
# Set output directory for STATIC libraries and executables
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${OUTPUT_PATH})
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${OUTPUT_PATH})
include_directories(${INCLUDES_PATH})
include_directories(${OpenCV_INCLUDE_DIRS})
# compilation of executables
message(STATUS "configuring executables...")
add_executable(mainTest ${SOURCES_PATH}/mainTest.cpp) # Use simple name as a target
# compilation of libraries
message(STATUS "configuring libraries...")
add_library(background_substractor ${SOURCES_PATH}/background_substractor.cpp) # Use simple name as a target
# set linker options
# Command below is no-op: OpenCV libraries enumerated using absolute paths
# link_directories(${OpenCV_LINK_DIRECTORIES})
target_link_libraries(mainTest ${OpenCV_LIBS}) # Variable OpenCV_LIBS contains OpenCV libraries needed to link with
target_link_libraries(background_substractor ${OpenCV_LIBS})
message(STATUS "cmake configuration complete")
