Multilib GDB on Linux S390x (zSeries)


Hi!

We are porting some software to linux for zSeries. The software uses MQSeries
that is only availabe for 32 bit. So we use the gcc with the -m31 switch.
The Appliction work but could'nt be debugged with gdb.

Trying to debug a helloworld.c compiled with the same switches
gcc -g -m31 helloworld.c

GDB complains:
This GDB was configured as "s390x-ibm-linux"..."/xentric/volkdir/src/a.out": not
in executable format: File format not recognized

I tried this with different versions from gcc/gdb and got allways the same
problem.
(gcc 3.3/3.2, gdb 5.3/5.2)
