Multilib GDB on Linux S390x (zSeries)

Multilib GDB on Linux S390x (zSeries)

[Dirk Volkmar]

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)

You need a 32-bit debugger for this,
