Fatal Error on compiling CameraControl Software

[VRabbitHole]

Just went through the install procedure for the CameraControl software and in the final compile section get this Fatal Error Message .... any suggestions on where I might have gone wrong (I'm not a C++ or C guy):

I met this error before and fixed it by changing the way to compile ffmpeg:

./configure --enable_shared

make

sudo make install

Best regards,

Thanks Ted ... will give it a whirl.

Have you actually built the 360 camera rig or just testing the software?

[IsaacZhi]

I had built the code.

First, you need compile share lib ( .so files ) for ffmpeg.
In the guide ( https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu ), it only guide you to compile the static lib ( .a files ) , you need add --enable-shared in ffmpeg and libx265 and etc.

Second, if you install ffmpeg to your local path, you need add the include path and lib path in CMakeList.txt .

Thank you, but could you please explain how exactly this is done?

[aparrapo]

@rezanvshield, assuming you have ffmpeg installed in <ffmpeg_path> you can do:

export LD_LIBRARY_PATH=<ffmpeg_path>/lib/
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:<ffmpeg_path>/lib/pkgconfig
export PKG_CONFIG_LIBDIR=$PKG_CONFIG_LIBDIR:<ffmpeg_path>/lib/

and run the cmake command again.

@rezanvshield closing this task for now. Please feel free to reopen it if the problem persists.
