John ,
I will check that too.
Thanks you !
Hi Gui,
I am wondering if it is related to the fact that I use g++ ?
Perhaps.
Are their headers -- audio.h, video.h, demux.h and/or dvbdrv_inf.h -- C++ savvy?
If they are not C++ savvy, perhaps the symbols from their headers in the C++ translation units are getting mangled the C++ way, but the symbols in their object files were mangled the C way.
(The "C way mangling" is probably either as-is, or prepended underscore. Not much mangled at all.)
You can use nm on the object files from both C and C++ to see if the symbols (mangled-or-not) are as expected. Use c++filt to turn mangled C++ symbols into human legible text.
HTH,
