Can you provide libs for the mingw compiler

[Mohamed Eldib]

Good day

if you kindly please provide, libs version for the mingw compiler,
because those are for ms compilers, and i am working with Qt which
gives me undefined reference when i am porting the project.

your answer is really appreciated

thanks for the great effort

regards

Mohamed Eldib

Please use the include file for version 4.0.

Everything should be made as simple as possible, but not simpler.

Hello,

when I try to compile it with eclipse cdt & cygwin I get this error:

Can you please explain to me why is this happening?

Hi,

if I try to compile it with MinGW I get this error:

How can  Iresolve this?

Thank you for your answer but I don't understand.

Here, I set up as library name "asmlibrary"

Here, I set up path for libraries:

And in the directory C:\asmlibraryFaceXpress

I have this three libraries: cygasmlibrary-4.dll, libasmlibrary.a, libasmlibrary.dll.a

Even if I set build configuration from Debug to Release I got the same:

16:02:49 **** Incremental Build of configuration Release for project AsmLibrarySDK_FIT ****

It doesn't matter if I compile with gcc from Cygwin or MinGW (they are gcc 4.7.3 and 4.7.2 version)

What I am doing wrong?

Code like this g++ a.c -o test libasmlibrary.a -lopencv_library

[Nenad Bulatovic]

Hello,

I am very sorry to btoher you again, but this just wont work. I even copied (cygasmlibrary-4.dll, libasmlibrary.a, libasmlibrary.dll.a) into both release and debug directory and tried to compile from command line with this:

g++ "-LC:\\OpenCV246MinGW\\x86\\lib" "-LC:\\asmlibraryFaceXpress" -o AsmLibrarySDK_FIT.exe vjfacedetect.o video_camera.o demo_fit.o libasmlibrary.a -lopencv_calib3d246 -lopencv_contrib246 -lopencv_core246 -lopencv_features2d246 -lopencv_flann246 -lopencv_gpu246 -lopencv_highgui246 -lopencv_imgproc246 -lopencv_legacy246 -lopencv_ml246 -lopencv_nonfree246 -lopencv_objdetect246 -lopencv_photo246 -lopencv_stitching246 -lopencv_video246 -lopencv_videostab246

But it won't work. I got the same error as described previously.
