The lines just above that are important:

The compiler is telling you that it saw "#include <glib.h>" inside an
extern "C" block, but that glib.h ultimately pulls in headers with C++
definitions. It looks like the glib headers already take care of
defining things correctly depending on whether they are being consumed
by a C compiler or a C++ compiler. Tell upstream to move all #include
statements for glib headers out of extern "C" blocks.
