I have tried this following steps,

1) Downloaded the TBB package.

2) Build using the below command

mingw32-make compiler=gcc arch=ia32 runtime=mingw default

3) I set the Environmental variable path

4) Now using cmake, I enabled "WITH_TBB" and compiled the opencv.

after that i got an error as 

[33%] Built target pch_Generate_opencv_core
Linking CXX shared library ..\..\bin\libopencv_core245.dll
c:/mingw/bin/../lib/gcc/mingw32/4.6.2/../../../../mingw32/bin/ld.exe: cannot fin
d -ltbb
collect2: ld returned 1 exit status
make[2]: *** [bin/libopencv_core245.dll] Error 1
make[1]: *** [modules/core/CMakeFiles/opencv_core.dir/all] Error 2
make: *** [all] Error 2

Can any one say how to overcome this issue and how to build the tbb for windows mingw ??

Uooo

  • using cmake gui: typically after enabling "WITH_TBB" (and clicking "configure" or how it is named once) there will come up a new field (colored red) where to tell the TBB lib path. – Micka Apr 29 '15 at 08:41
  • yea , the new field came in that i gave the tbb include directory path to it. – Jaya Balaji Venkatachalam Apr 29 '15 at 12:11
