Hi, I would like to compile a FFI program but the compiling implies compile flags like in the following : gcc -Wall helloworld.c -o helloworld $(pkg-config --cflags --libs gstreamer-1.0) How do I do this with FFI ? Annick
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 ? If you want to compile your library using FFI, then use OSProcess to run the compilation line you showed. If you want to bind a library compiled your way with FFI, the easiest way is to compile the C files as a dylib with something like: *gcc -shared -m32 -Wall helloworld.c -o helloworld.dylib $(pkg-config --cflags --libs gstreamer-1.0)* (replace .dylib by .so or .dll if you're on windows or on Mac). Then you can bind the dynamic library generated with FFI. I am not sure about the FFI syntax but with NativeBoost it would look like: Integer>>fib4NB <primitive: #primitiveNativeCall module: #NativeBoostPlugin error: errorCode> ^ self nbCall: #( int functionToCall (int self) ) module: '/Users/myName/Desktop/helloWorld.dylib' Regards, Clement 2014-08-13 11:55 GMT+02:00 Annick Fron <info@afceurope.com>:

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 donât 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.

Annick FFI can call a function but it needs to know where is your library. Stef On 13/8/14 15:46, Annick Fron wrote:

Steph We had a Skype call yesterday with JB, and we made progress. The problem is I have several libraries, and it was not easy to find because they donât export symbols and use pkg-config. See you in Cambridge Annick Le 15 août 2014 à 12:36, stepharo <stepharo@free.fr> a écrit :
