When compiling for ARM and uClibc, gcc-8.3.0 complains about comparison
of integer expressions of different signedness:
../../src/v4l2/v4l2_camera_proxy.cpp: In member function ‘void* V4L2CameraProxy::mmap(void*, size_t, int, int, off_t)’:
../../src/v4l2/v4l2_camera_proxy.cpp:88:25: error: comparison of integer expressions of different signedness: ‘unsigned int’ and ‘off_t’ {aka ‘long int’} [-Werror=sign-compare]
if (index * sizeimage_ != offset || length != sizeimage_) {
~~~~~~~~~~~~~~~~~~~^~~~~~~~~
Fix the compilation error with a cast.
