Just FYI x-posted to linuxppc-embedded
Hello, James!
Thank you for your hints...
In the meanwhile as I experienced some other strange issues with my gcc-3.3.3 toolchain, I concentrated to upgrade to the latest
mainstream gcc-3.4.3. It also failed during bootstrapping in
the beginning, but after a 'two-iteration' bootstrap I was able
to move up to 3.4.3:
Here is my buildlog:
./gcc-3.4.3/configure
--enable-languages=c
--enable-shared
--enable-threads=posix
--enable-__cxa_atexit
--enable-nls=yes
--enable-clocale=gnu
make bootstrap
failed with an occasional segfault but let's give it a second chance
make bootstrap
which finished successful!
make install
Ok, now I have a working gcc-3.4.3 at least - well, for c only!
but let me now try a
make distclean
../gcc-3.4.3/configure
--enable-languages=c,c++,objc
--enable-shared
--enable-threads=posix
--enable-__cxa_atexit
--enable-nls=yes
--enable-clocale=gnu
make bootstrap
and voila! successful!
make check
make installOkay, now, I am back to installing Qt... which also works fine. uic doesn't crash anymore. I am pretty sure that my initial toolchain (ELDK3.1 for ppc_8xx) was somehow broken.
The next step is to get optimized code for the mpc8540 but that's low priority now.
Best greets,

uic is dumping core. We can't really do anything about that, as that isn't part of gcc. We need a testcase that we can use to reproduce the problem, or evidence of an actual gcc problem.
If this is a gcc miscompilation problem, and you are compiling with a high optimization level like -O2, you could try using -O or -O0 instead.
You could try using a different gcc version. Maybe gcc-3.3.4 has a bug that isn't present in other earlier or later gcc-3.3.x versions.
You could try debugging uic to figure out why it is failing.

There are people supporting the e500 target, so it should be working reasonably well in any gcc release.
There is a special branch maintained for the e500 by Red Hat, which is called gcc-3_4-e500-branch. This can be checked out from our cvs repository. I don't know details about this branch other than what is on the web site.

and scroll down to the Architecture-specific section.
