[Solved] Cannot link libs statically

[liimyd]

I rebuilt opencv, this time with BUILD_SHARED_LIBS = Off, which made .a files.
I read that .a files are the same as .lib files.
My .pro file now looks like this:

INCLUDEPATH += C:\\Programs\\opencvMinGW5\\install\\include

LIBS += -LC:\\Programs\\opencvMinGW5\\install\\x64\\mingw\\staticlib \
-lopencv_core300 \
-lopencv_highgui300 \
-lopencv_imgcodecs300 \
-lopencv_imgproc300 \
-lzlib \
-lIlmImf

I have a few compilation errors, and I wasn't able to google them, do you know what they mean?

I think I might be missing some static libs or maybe the order I'm listing the libs is wrong.

There's something not clear, I see MinGW5 in your OpenCV path and Qt uses 4.9.1, which one did you use to build OpenCV ?

[liimyd]

OpenCVMinGW5 is just the name of the folder for my Cmake files (my sad 5th attempt at building OpenCV). I used 4.9.1 to build. Sorry for the confusion.

Hi, I'm still looking for help with this; I was wondering if you had any suggestions. Thank you for your help so far though!
