Thanks.
So, where in<JAVA_HOME>/ is the libjvm.so located?
I could then patch it into pre_install.m.
There's no such thing on OS X, but:
$ javaconfig Library
/System/Library/Frameworks/JavaVM.framework/Libraries/libjvm.dylib
$ realpath
/System/Library/Frameworks/JavaVM.framework/Libraries/libjvm.dylib
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Libraries/libclient.dylib
I.e. the real JVM library is<JAVA_HOME>/../Libraries/libclient.dylib .
Well, could you please try attached pre_install.m?
Hopefully I've entered the proper stuff for Mac OSX.
Feel free to adapt it where you see fit.
Thanks,
Philip
