Re: [Pharo-users] FFI on MacOS 10.12 using Pharo 5

Hi, I never tested it with a “bundle” plugin. But if before it worked like this: someNumber <cdecl: int 'someNumber' () module: 'ThePlugin'> ^self externalCallFailed Now it should work like this: someNumber ^ self ffiCall: #(int someNumber () ) module: ‘ThePlugin’. and: a) you can do that with a FFILibrary child, in which case it will be something like this: ThePlugin>>macModuleName ^ ‘ThePlugin' someNumber ^ self ffiCall: #(int someNumber () ) module: ThePlugin. “Class reference, no need to put uniqueInstance” b) bundles needs to be put where bundles go: Pharo.app/Contents/Resources cheers, Esteban

Hello,

I need help rescuing code that has dependencies on FFI. I just downloaded the latest Pharo 5 vm in order to run Pharo under MacOS 10.12. Now the FFI-based code in my image no longer works (or is viewable).

What worked before (for years, up through MacOS 10.11) is as follows:

I have a 32-bit lib (i386) called ThePlugin.bundle (C code compiled w/ Xcode). I put it in Pharo.app/Contents/MacOS/Contents/Plugins/.

The lib has a C function like: int someNumber() { return 123; }

In Smalltalk I have a class ThePluginFFI with the class method: someNumber <cdecl: int 'someNumber' () module: 'ThePlugin'> ^self externalCallFailed

And if I typed "ThePluginFFI someNumber" I got 123

Now I get "External module not found". If I try to view the method "someNumber" I get an MNU from RBFFLCallPragma>>selectorParts (receiver of "keywords" is nil), and the image hangs.

I tried rewriting the method someNumber to look like this: someNumber ^self ffiCall: #( int someNumber() ) module: ThePlugin uniqueInstance

where ThePlugin is a subclass of FFILibrary with an instance method: macModuleName ^'ThePlugin.bundle'

but this still gets "External module not found"

Is there some new way of doing all this? Or some new trick to loading libraries (I tried dylibs as well as bundles).

I couldn't find a recent summary/update.

Thanks for any help! Jay
