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
