[squeak-dev] Problem installing Alien

When installing Alien (after last upgrades in trunk) I have the
following error:

MessageNotUnderstood: TempVariableNode>>doesNotUnderstand: #code
It happens in AlienInstaller>>install

Hi Casimiro,

this will most likely have something to do with the recent closure fixes.

Too good Alien isn't a standard package, eh? ;-)

Hi,

the issue is solved. Using AlienInstaller-mha.5 from
source.squeak.org/treated in an up-to-date trunk image, Alien can be
loaded.

For me (on a Mac), most of the tests pass; three don't - the ones that
try to load and use libc. The reason is that a primitive fails:
AlienLibrary >> primLoadLibrary. I'm trying to figure out what is
wrong.

Could someone please try Alien on another platform and see whether (a)
Alien installation works, and (b) the problem is observable there?

Best,

Michael

And hello again,

with some crucial help from a friend of mine, who also happens to be a
Darwin expert, I was able to fix this. The trouble is that the VM uses
LoadFrameworkBundle() internally, which expects a framework, not a
shared library. However, LibCLibrary>>libraryName would, on Mac OS,
return 'libc.dylib', which is a shared library but not a framework.

Replacing this with
'/System/Library/Frameworks/System.framework/System' does the trick.

John, would it be OK if I upload that fix to the repository? Or will
it break on older Mac OS X versions, i.e., before Snow Leopard?

Best,

Michael

I have uploaded the fix to the Alien repository.

Best,
