I don't understand, do you want to compile your library using FFI or do you want to bind a library compiled your way with FFI ?

Re: [Pharo-users] FFI with compile flags
I want to interface some pharo code with gstreamer. But gstreamer does not come up with a dylib, it requires compilation flags for instance for a C program. The compile options are : -pthread -I/usr/include/gstreamer-1.0 -I/usr/include/glib-2.0 -I/usr/lib/i386-linux-gnu/glib-2.0/include -lgstreamer-1.0 -lgobject-2.0 -lglib-2.0 so if I don’t know which module to use in FFI. If I put /usr/lib/gstreamer-1.0 I get an error « module not found ». Since it is handled by pragmas it is very difficult to debug.
