[squeak-dev] Problems with FFI, SqueakDBX and MacOS

Hi people: I am asking for help with squeakDBX in mac. Yes, I am one of the developers, so ? heheheheh

The thing is that Michael Atkisson is trying to getting working and have problems. As I know very little about mac, I ask for help.

The problem is that FFI is not founding the openDBX library. The error is the famous "unable to find function address'".

This is his enviorment:

- Image: the 201 core, updated using the system update.
- Squeak vm: 3.8.18beta3U.app
- OS: Mac osx 10.5.6

- FFI instaled from here:  http://map.squeak.org/accountbyid/cf58c358-46ee-465e-b6db-2740e9b32a53/files/InstallFFI3.st


- DYLD_LIBRARY_PATH="/usr/local/lib/:/usr/lib" .....

- PATH=/usr/lib:/usr/local/lib:other entries ....

- Check the property SqueakPluginsBuiltInOrLocalOnly in Info.plist de la VM  was in true but changed to false.

- The ls of the directories of /usr/local/lib and /usr/lib are above.

- We also try to put the openDBX library in the directory where is the VM or the image, but the same.

- I read this: http://wiki.squeak.org/squeak/5846
Is this true ? I mean, FFI doesn't support dylib ? what can I do in this case ?


Thanks for all the help you can give us.

Mariano

Hi Mariano,

I am not a Mac user, but I think that this wiki page has some
out of date information, and the last paragraph is a correction
to say that the Mac VM does suppert dylib. So it *should* work.

Unfortunately I do not know enough to say what the problem is.
Hopefully others will give a better answer.

Set SqueakDebug to 1 and it will print lots of information about where  
it's trying to find the indicated library.
You will need to start the VM from a terminal session command line to  
see the log messages


When SqueakPluginsBuiltInOrLocalOnly is false we look in more places.

environment variables it uses are:

SQUEAK_PLUGIN_PATH
VM_LIBDIR
VM_X11DIR

We also hunt in the *.apps resources folder
standard Plugins directory
the current directory ./
the vm directory
and lastly frameworks in

        "/CoreServices.framework/Frameworks",
        "/ApplicationServices.framework/Frameworks",
        "/Carbon.framework/Frameworks",


When SqueakPluginsBuiltInOrLocalOnly  is true we only look in

the *.apps resources folder
standard Plugins directory
and lastly frameworks in

        "/CoreServices.framework/Frameworks",
        "/ApplicationServices.framework/Frameworks",
        "/Carbon.framework/Frameworks",
