Description

Hi!

I've used r8126 under Win7 32 bit, compiling with MinGW, without gpu and cuda.

It gives following log:

[ 20%] Building CXX object modules/core/CMakeFiles/opencv_core.dir/src/tables.cpp.obj

Does anybody know what's the reason may be?

Vlad, could you see this?

The reason was CV_EXPORTS macro used inside anonymous namespace. r8131 should fix this problem.

  • Status changed from Open to Done
