FFI Basic

Hi,

I made another attempt , a very basic one on window : trying to use the abs method in the standard lib.

abs: aNumber

<apicall: int 'abs' (int) module: 'c:\windows\system32\msvcr100.dll'>
self externalCallFailed

I get the error ‘cannot return the given type’.

But now if I use long as argument and long as return it works.

Re: FFI Basic

Well the method with the code you give was compiled without any problem in my image (Pharo #30851 with FFI loaded with configuration browser as explained in the other thread).

Perhaps this is related to your bug in the other thread where you were (probably) missing a package ?
