ARM-simulator problem (undefined target)

ARM-simulator problem (undefined target)

[Ferenc Kovacs]

Hello!

I need to test some ARM/THUMB executables in GDB but i
have some problems building a working simulator. I configured 
GDB-6.3 with these command line options:

./configure --target=arm-unknown-linux --prefix=$INSTALL_DIR

When i enter "target sim" on GDB's prompt, i get the
following message:

Undefined target command: "sim". Try "help target".

The "help target" lists only exec, remote, async, etc. but
no sim. I think my target ("arm-unknown-linux") matches
the "arm*-*-*" pattern in gdb-6.3/sim/configure and i have the
libarm-unknown-linux-sim.a in the $INSTALL_DIR/lib directory,
but it's still not working...

Could somebody tell me what can be the problem??

Thank you!

Feri

The simulator doesn't get linked in for arm-linux.  I'm not sure if
this is a bug or a feature, to be honest.  Try arm-elf.

If folks think arm-linux should include the simulator, I have a patch
around here somewhere to add it...

The arm-elf simulator works ok and i think it'll do the job, but if you 
find that arm-linux patch could you send it??

Thanks!
