[platform-swt-dev] Compiling of GCJ and SWT under MacOS X
|
Hi.
I have downloaded gnu gcc 3.4.3 and compiled it with the following command line
parameters :
configure --prefix=/usr --enable-languages=c,c++,java,f77,objc
--enable-threads=posix --enable-shared
make bootstrap
make install
Now this compiles everything fine under MacOS X.3 using the gcc compiler that
comes with the Developer Tools ie. gcc 3.3
When I compile a Hello World program using gcj, like so :
gcj Test.java -o Test --classpath /usr/share/java/libgcjxxx.jar:$CLASSPATH
--main=Test -lgcj
Then it compiles fine and the output from the program is as expected.
But. When I try to link against the libswt-carbon-xxxx.jnilib all hell breaks loose. I
have tried to make a symlink from *.jnilib to *.dylib and even to .a. When I do a file
on the jnilib it says it's a bundle.
I have tried to copy the jnilib files
into /System/Library/Frameworks/JavaVM.framework/Libraries and linking the
program as follows.
gcj Test.java -o Test --classpath /usr/share/java/libgcjxxx.jar:$CLASSPATH
--main=Test -lgcj -framework JavaVM
which fails.
When I do an ld style
ld Test.o -o Test -lgcj -framework JavaVM then it gives me an error that no __main is
found hence the --main=Test option.
when doing a gcj Test.o -o Test -lgcj libswt-carbon-xxxx.jnilib it fails as well telling
me that i can't call a static link editor using a dynamic link editor or something like
this. And this is where I'm struggling with.
I mean if I link against any other jnilib in the JavaVM framework it compiles
correctly. Maybe the jnilibs shouldn't be bundles ???
My long winded questions is :
1) Is my gcc configuration flags correct ?
2) How do you compile a program natively using the swt-carbon-xxxx.jnilib's ? If
you have a MacOS specific example could you please supply me with it.
I have been struggling with it for over a week now and I'm lost....
PLEASE....... Help me.
