This is very simple - you just have to link againsT PCSC framework!

Note that commands to make a JNI library are coming from Apple's
Java14Development.pdf .
I think I have problems with method headers. So today I am going to
generate them again. Since I am compiling the package manually, I
think there're some unresolved symbols into the code.
About XCode (version 2.0), you can develop a JNI application.
There's a Wizard for you. It creates a default libjpcsc.c file, a
default JNIWraper.java file, and goes generating a JNIWrapper.jar
archive, a JNIWrapper.h header file and libjpcsc.jnilib file. I
changed default file names coming from Wizard to adapt the
environment to my needs but when I go compiling XCode still looks
for old file names and I didn't find the place where to really
change them.
Anyway, I am trying to convert the original package coming from
Muscle into one for XCode developers (or at least, for Mac
developers).
Of course, if you have checked out the error messages I wrote you
before and you have an idea about how to solve the problem, let me
know as well.
Thank you.
Daniele.
