Hello,

This bug happen both with the old and new compiler.

The error tells you that the number of arguments of your smalltalk method does not match the number of argument of the C method you want to call (but it seemsthe number of arguments is correct).

This works fine:

��<apicall: int 'gst_init_check' (int char* int) module: 'libgstreamer1.0-0.so'>
^self externalCallFailed ����

This works fine too:

<apicall: int 'gst_init_check' (int* char* int*) module: 'libgstreamer1.0-0.so'>
^self externalCallFailed ����

So it seems the bug comes from the parser missparsing ** . I am not familiar with C enough to help, I don't know what means ** (Is it a pointer pointing to a pointer pointing to the actual data ?).��

Perhaps someone who knows how to use FFI can give a better answer.

Esteban ? Guille ?

Hi,


I am trying to use FFI on linux with pharo 3 using version 31 of FFI.

I have written the following method :

��<apicall: int 'gst_init_check' (int* char** int*) module: 'libgstreamer1.0-0.so'>

^self externalCallFailed

but when accepting it I get a syntax error ����matching number of arguments����
