I am trying to change JNIPort such that it uses NativeBoost instead of Alien.
The first problem I ran into is that I can't load a function from the Java
VM library libclient.dylib on OS X 10.8.5 in Pharo 2.0. I am using the 1.6.0
JDK from Apple, and libclient.dylib is an i386 (i.e. 32 bit) library. The
following expression answers nil:
NativeBoost
loadFunction: 'JNI_CreateJavaVM_Impl'
from:
'/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Libraries/libclient.dylib'
The same happens when I copy libclient.dylib to the working directory and do
not specify a path. The only way to produce a different behavior is copying
the library into the Pharo2.0.app bundle and put it in the directory
Pharo2.0.app/Contents/MacOS/Plugins. Then, executing
NativeBoost loadFunction: 'JNI_CreateJavaVM_Impl' from:
'libclient.dylib'
crashes Pharo when attempting to load the library:
Crashed Thread: 0 Dispatch queue: com.apple.main-thread
Exception Type: EXC_BAD_ACCESS (SIGABRT)
Exception Codes: EXC_I386_GPFLT

Any ideas what is wrong?
