[Qemu-devel] ARM emulation issue with MICO (CORBA) test

[Karel Gardas]

Hello,

after some time I have tested Qemu with ARM emulation on MICO project
bench demo. I've tested both statically and dynamically compiled demos,
but w/o success. In both cases server starts just fine, but when client
attempts to connect to server, server crashes. My qemu sources are from
this week (don't remember exactly). I have compiled gcc as an arm cross
compiler by using excelent Dan Kegel's crosstool-0.28-rc13 and I have
chossen to use gcc-3.4.0-glibc-2.3.2 combination.

If you are curious to test it yourself, then please download

mico.org/~karel/server.bz2
mico.org/~karel/client.bz2

Those are statically linked binaries and I have tested them myself by
running on handhelds.org skiff farm. They run well. You just need to start
server first:

./server -ORBIIOPAddr inet:localhost:1234

and then client against it:

./client inet:localhost:1234

usuall output of client is:

ABC.DEFG ms per call (e.g. ``7.81353 ms per call'')

Qemu based sesion looks:

thinkpad:/mnt/karel/mico-dev-arm-static/demo/bench$ qemu-arm -L
/mnt/karel/cross-gcc/result/arm-unknown-linux-gnu/gcc-3.4.0-glibc-2.3.2/arm-unknown-linux-gnu/
./server -ORBIIOPAddr inet:localhost:1234 &

/mnt/karel/cross-gcc/result/arm-unknown-linux-gnu/gcc-3.4.0-glibc-2.3.2/arm-unknown-linux-gnu/
./client inet:localhost:1234
qemu: uncaught target signal 11 (Segmentation fault) - exiting

[1]+  Exit 245                qemu-arm -L
/mnt/karel/cross-gcc/result/arm-unknown-linux-gnu/gcc-3.4.0-glibc-2.3.2/arm-unknown-linux-gnu/
./server -ORBIIOPAddr inet:localhost:1234
thinkpad:/mnt/karel/mico-dev-arm-static/demo/bench$

Any ideas what is wrong?

Thanks,

Karel
