I want start playing with the OpenCV library, but I have a problem during the build process. I am on Windows 10 with the Mingw compiler. When I launch the command mingw32-make after a while, I get the following errors:
C:\Github\opencv\modules\videoio\src\cap_dshow.cpp:337:21: fatal error: strsafe.h: No such file or directory
#include <strsafe.h>
^
compilation terminated.
modules\videoio\CMakeFiles\opencv_videoio.dir\build.make:187: recipe for target 'modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_dshow.cpp.obj' failed
mingw32-make[2]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_dshow.cpp.obj] Error 1

mingw32-make[1]: *** [modules/videoio/CMakeFiles/opencv_videoio.dir/all] Error 2
Makefile:159: recipe for target 'all' failed
mingw32-make: *** [all] Error 2
The incriminated file is cap_dshow.cpp, and the compiler says that is missing the header file strsafe.h. Inside the folder C:\MinGW\include this file is not present and I don't know where to find this.
I've installed MinGW compiler (and other things) with a tool called "MinGW Installation Manager". With this tool I can install also other libraries, but I don't know if one of these contains the file strsafe.h.
My question is likely a duplicate of this, but the accepted answer has a broken link.
I have Microsoft SDK installed and found the strsafe.h file in "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin".
Adding "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin" to the Path system environment variable worked.

I'm working on a cmake project which linked to boost libraries. I want to link to shared boost_unit_test_framework and static the others. A part of cmakelists.txt as below:
set(Boost_USE_STATIC_LIBS on)
add_definitions(-DBOOST_TEST_DYN_LINK)
find_package (Boost REQUIRED COMPONENTS timer system OPTIONAL_COMPONENTS chrono)
find_library(boost_test boost_unit_test_framework /opt/boost/lib)
set (TEST test-suite)
add_executable (${TEST} ${Test_SRC})
message(STATUS "##########################${boost_test}")
target_link_libraries (${TEST} ${boost_test})
target_link_libraries (${TEST} ${Boost_LIBRARIES})
I tried to build it in a docker container, link errors reported:
/usr/bin/ld: cannot find -lboost_unit_test_framework
collect2: error: ld returned 1 exit status
make[2]: *** [QuantLib/test-suite/CMakeFiles/quantlib-test-suite.dir/build.make:1574: QuantLib/test-suite/quantlib-test-suite] Error 1
make[1]: *** [CMakeFiles/Makefile2:1267: QuantLib/test-suite/CMakeFiles/quantlib-test-suite.dir/all] Error 2
make: *** [Makefile:163: all] Error 2
Some information:
1.My cmake version is 3.11.4; boost version is 1.74, installed under /opt/boost.
2.If I build it on a linux server, there is no error; If I build it in a docker continer, errors emited. The docker continer has almose same settings with the linux server: centos8.1/cmake3.11/boost1.74
3.${boost_test} message in cmakelists.txt show a full path: /opt/boost/lib/libboost_unit_test_framework.so
4.Make a soft link to libboost_unit_test_framework.so under /usr/lib can fix the error, but I don't want to change the container environment. I want to fix it in CMake.
5.Shared libs:
Any idea?
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.

## LuaDist is now built and can be found in C:\Users\User\_bootstrap\_install
At the end it says that LuaDist is built in C:\Users\User_bootstrap_intall , but that folder doens't exist after the installation.
I am trying to compile OpenCV 2.4.13.4 with Mingw64-GCC-5.1 on Windows 10but I keep receiving the following error:
[ 95%] Generating perf_precomp.hpp.gch/opencv_perf_stitching_Release.gch
g++.exe: error: unrecognized command line option '-Wo-array-bounds'

Please note that there is no typo here, -Wo-array-bounds is exactly the output I receive ( and not -Wno-array-bounds that google search suggests!). Any idea how to solve the problem? I searched for -Wo-array-bounds in the entire build folder to possibly change it to -Wno-array-bounds but I couldn't find this command line option in any file located in the build folder.
I'm trying to build OpenCV with CUDA support using Arch Linux's AUR. In their build configuration some options are passed to CMake, I have modified those to add CUDA features. Upon attempting compilation I get the following error:
[ 10%] Built target pch_Generate_opencv_reg

make[1]: *** [CMakeFiles/Makefile2:6834: modules/cudacodec/CMakeFiles/opencv_cudacodec_pch_dephelp.dir/all] Error 2
I searched my filesystem and found the rogue header file in /usr/include/nvidia-sdk/dynlink_nvcuvid.h. Due to how AUR works, I believe I can only configure CMake via command line options (See links 1, 2 under _cmakeopts=...).
What argument can I pass to CMake to make it search for the appropriate libraries under the aforementioned directory, as well as the ones it already uses?
I was trying to install clang_complete on OSX 10.9.4. However while running make I get the following error:
[ 66%] Building CXX object CMakeFiles/clic_add.dir/clic_add.cpp.o

1 error generated.
I have clang, llvm-g++ and llvm-gcc. How do I resolve this error?
You can download source code for clang
svn checkout http://llvm.org/svn/llvm-project/cfe/trunk
The header should be in the include/clang-c folders, you can edit the cmake file and pass in the location of the header in the CPP flags (-I)
cmake file would be here:-
ycm/CMakeFiles/ycm_core.dir/flags.make
