Description

Hi,

I am trying to use OpenCV in a project, that will use the stdcall calling convention.
OpenCV is compiled as cdecl, but the header files do not declare the free and static functions with +cdecl.

Compiling OpenCV manually as stdcall failes, because internal functions, that are for example passed as function pointers to qsort in stdlib.h (which requires cdecl), are not declared properly.

I did not find a way (bending #defines etc.) to get OpenCV to use stdcall without hacking around in the code.

Because I can not compile my project cdecl, I modified the OpenCV header files, so that the free and static functions now use CV_CDECL.

Is there an easier way to work around this problem or should this be corrected in future versions of OpenCV?

Regards,
Dobias

lowering priority of the bug, since not many people complained about it. And it's too much work to mark all the functions and static methods as CV_CDECL.

OK. We changed our project to cdecl anyway because it was less work than manually editing the OpenCV header files with every new release. ;-)

as we hardly ever do this, let's just cancel the ticket
