I'm on Ubuntu 20.4.6, I try to compile OpenCV using the qcc QNX compiler. In OpenCV build from source instructions they use the following command to generate their build files:
cmake -DCMAKE_BUILD_TYPE=Release \
-DCMAKE_INSTALL_PREFIX=/usr/local \
-DINSTALL_C_EXAMPLES=ON \
-DINSTALL_PYTHON_EXAMPLES=ON \
-DOPENCV_GENERATE_PKGCONFIG=ON \
-DOPENCV_EXTRA_MODULES_PATH=~/opencv_build/opencv_contrib/modules \
-DBUILD_SHARED_LIBS=OFF \
-DBUILD_EXAMPLES=ON ..
I thought of adding the C compiler and CXX compiler flags (CMake) to indicate to CMake to generate using qcc compiler like so:
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=qcc -DCMAKE_CXX_COMPILER=qcc \
-DCMAKE_INSTALL_PREFIX=/usr/local \
-DINSTALL_C_EXAMPLES=ON \
-DINSTALL_PYTHON_EXAMPLES=ON \
-DOPENCV_GENERATE_PKGCONFIG=ON \
-DOPENCV_EXTRA_MODULES_PATH=~/opencv_build/opencv_contrib/modules \
-DBUILD_SHARED_LIBS=OFF \
-DBUILD_EXAMPLES=ON ..
When I try and run the make command, to start the build process, I get many errors and warnings and eventually the build fails. I also tried to use Ninja but same thing happened.
Example erros:

Anyone knows how to use the qcc QNX compiler on a project, or if there are better compatible open source projects out there to be used with qcc?
