Install TBB + OpenCV + Qt
Greetings.
I have several weeks trying to install OpenCV 2.4 + TBB 4.1 + QT5 on Windows 7 and can not.
I perform the following steps (in the order they are listed):
(1) I install QT5, specifically: Qt 5.0.2 for Windows 32-bit (MinGW 4.7). This I download from http://qt-project.org/downloads.
After installation, I add "C:\Qt\Qt5.0.1\Tools\MinGW\bin" to the PATH environment variable (I'm not sure this is necessary or at least helpful).
(2) I downloaded (from http://threadingbuildingblocks.org/download) and built TBB 4.1 (Source), specifically: tbb41_20130314oss_src.tgz
I extract this in the path "C:\TBB" and built it with: mingw32-make compiler=gcc arch=ia32
Then I add the system environment variable
"TBBDIR = C:\tbb\tbb41_20130314oss"
and add "%TBBDIR%\build\windows_ia32_gcc_mingw4.7.2_release" to the PATH environment variable. (again, I'm not sure this is necessary or at least helpful)
(3) I downloaded OpenCV (in the path C:\opencv\source) using msysgit + TortoiseGit (following this tutorial http://uncod.in/blog/installing-msysgit-on-windows7/).
(4) Then build OpenCV using CMake 2.8.10.2-win32-x86.
I do a debug (putting CMAKE_BUILD_TYPE = Debug) in the path "C:\opencv\builds\debug" and then a release (putting CMAKE_BUILD_TYPE = Release) in the path "C:\opencv\builds\release".
In both cases I check the options WITH_QT and WITH_TBB and uncheck WITH_CUBLAS, WITH_CUDA, WITH_EIGEN and WITH_CUFFT.
After that I open a command console, I move to the path "C:\opencv\builds\debug" (where the project debugging) and run the following command:
mingw32-make
When the process goes to 33% completion, I get the following error message:
Linking CXX shared library .. \ .. \ bin \ libopencv_core249d.dll c :/ qt/qt5.0.1/tools/mingw/bin/../lib/gcc/i686-w64-mingw32/4.7.2/../../../../i686 -w64-mingw32/bin/ld.exe: can not find-ltbb collect2.exe: error: ld returned 1 exit status modules \ core \ CMakeFiles \ opencv_core.dir \ build.make: 740: recipe for target `bin / l ibopencv_core249d.dll 'failed mingw32-make [2]: * [bin/libopencv_core249d.dll] Error 1 CMakeFiles \ Makefile2: 1084: recipe for target 'modules / core / CMakeFiles / opencv_cor e.dir / all 'failed mingw32-make [1]: [modules / core / CMakeFiles / opencv_core.dir / all] Error 2 Makefile: 115: recipe for target 'all' failed mingw32-make: ** [all] Error 2
I really do not know what the cause of this problem or how I can fix it (at least a few options). Thanks in advance for any help and/or suggestions.
