Hi Joachim, JNIPort sounds really great and I will test it. It is really great to have these kind of bindings. For your Alien problem on Cog, I also experienced some troubles with the library path. So I am pretty sure that the problem is on the Cog side. Perhaps the Alien plugin compiled in Cog. I would like to do more investigations on that. #Luc 2011/2/5 Joachim Geidel <joachim.geidel@onlinehome.de>

What are the impediments of getting it to work with Cog on Pharo?
JNIPort relies on Alien, and I have not yet found a Cog VM working with Alien and JNIPort.
I tried Squeak 5.8b12 for Mac OS X which identifies itself as Cog, but it crashes when you just evaluate "LibCLibrary uniqueInstance". Apparently this VM version doesn't work with Alien.
Eliot's latest Cog build for Mac OS X at http://www.mirandabanda.org/files/Cog/VM/VM.r2349/ is able to load libc. When I try to use JNIPort, it can't find the library libjvm.dylib when I create a symbolic link to it in the working directory. When I create a symbolic link in the subdirectory Cog.app/Contents/Resources, it is able to load the library, but the VM crashes with a bus error when I try to call the first function of the library. I currently have no idea what causes the error. As the same code runs without problems on a Squeak VM, I don't think that the problem is in the JNIPort code, but I may be wrong.
So, no JNIPort on Cog for now. This may change soon, of course.
