Oh look SUnits, great stuff (*cough* well I wrote most of them).
Cool, this is really really useful (although I sometimes find wrting tests boring ;) ).
It is failing in places where it does primLoadLibrary: 'IA32ABI'. Why should it try to load itself, if it's compiled as an internal plugin? I compiled it as external too but didn't work either.
Well it compiled, but that doesn't mean it works. In fact the error means the plugin code is never loaded, or is callable.
Now one thing to consider is that the plugin load fails, because it can't find it. (external usage).
Or because (internal and external plugin) the VM Version and the plugin version don't match.
Look for your definition of
#define VM_PROXY_MINOR 8
It should be 8 or higher for compiling BOTH the VM and the Plugin.
Since the sqVirtualMachine.h is in the IA32ABI folder maybe there is mass confusion about which header is being used?
If for example your VM say it's a VM_PROXY_MINOR of 7, then it won't work with a plugin compiled with VM_PROXY_MINOR = 8.
It silently fails... Well actually it gives the primLoadLibrary failure, but good luck in guessing why...
Well, I just overwrote sqVirtualMachine.c/h in Cross/vm, shouldn't have I? It wouldn't compile if I didn't and its sets it to 8. Is it defined in any other place?
Other question, can classic FFI and Alien live nicely together (I mean have x plugin use classic FFI while y uses Alien)?
yes.
One more: should I use IA32ABIPlugin or IA32ABIPluginAttic? You can't have both in, right?
One is a subclass of the other. I use the IA32ABIPluginAttic one.
Ok, what is the difference between them? a performance issue? everything works the same I choose one or the other?
Syntax highligthing is broken for Alien primitive methods like these:
<primitive: 'primUnsignedShortAtPut' error: errorCode module: 'IA32ABI'>
Lastly, as I said when I loaded Alien Core the first time, I got this error while loading it:
Alien class>>#ensureInSpecialObjectsArray: "Index probably wrong".
What should I do about that? ignore it?
Well it seems to be related to
((Smalltalk includesKey: #ObjectMemory)
and: [((Smalltalk at: #ObjectMemory) classPool at: #ClassAlien ifAbsent: []) ~~ (index - 1)]) ifTrue:
[self error: 'index probably wrong'].
Usually people don't have ObjectMemory loaded in their image, and I"m not sure what it is check for.
Why don't you try it in a regular Pharo image versus your VMMaker image.
In Pharo 1.0RC2 without any change, ObjectMemory doesn't exist. When I load VMMaker it's downloaded from monticello, but obviously, #ClassAlien isn't defined inside
(Smalltalk at: #ObjectMemory) classPool
Interestingly, after load alien, #ClassAlien gets added as a key, but all values of (Smalltalk at: #ObjectMemory) classPool are set to nil, like this:
(Smalltalk at: #ObjectMemory) classPool inspect:
- size : 119
