Can you give me a small example how to do that? Under linux I have made
a little example, which does the trick:

---- shared lib example:

## Makefile:

all: testshl_static testshl
clean:
        rm -f testfunc.o main.o libtestshl.so testshl testshl_static

testshl_static: testfunc.o main.o
        gcc -o testshl_static testfunc.o main.o

libtestshl.so: testfunc.o
        gcc -shared -o libtestshl.so testfunc.o

testshl: libtestshl.so main.o
        gcc -o testshl main.o -L. -ltestshl

## main.c

extern void testfunction();

main()
{
        printf("---- calling external testfunction ...: -------------\n");
        testfunc();
        printf("------------------------------------------- done ----\n");
}

## testfunc.c

void testfunc()
{
        printf("This is the output of the testfunction\n");
}

---- 

What exactly is to do to make this compile under Aix? Then I could look if
I can get qt to compile as shared library, and perhaps even try to look at
libtool. This would make things much better and more elegant on Aix.

This is definitly possible. Perhaps you'll need to exclude kdm from
compilation, but everything else will be possible. Look at

      http://space.twc.de/~stefan/kde

I explained what else you might need to do there. Otherwise write me,
perhaps I can help you.

Ok, I can't help there since I have no xlC available to play around with.
We should try to make both work (gcc with shared libs, and xlC as well),
and the binaries that looks better/more stable or are ready earlier should
be but onto the FTP site.

If you would be able to build them for all those systems it would be great.
So we only need to fix the remaining problems in libtool and QT makefile,
then we can start.
