Re: SIGTRAP error

[nora pan]

Hello, Rohit:

You may want to try the patch for fixing PR 1944 at 
http://sources.redhat.com/cgi-bin/gnatsweb.pl. The patch is against
head gdb.

Gdb 5.3 may be too old. Most of the time people would try the latest
release to see if the fix is there.

Thanks,

Qunying

Re: SIGTRAP error

[Rohit Agarwal]

hi
i got the source for gdb-6.3. applied the patch
"gdb-6.3-load-remote-target-bug.patch".
next i configured gdb by typing "./configure --prefix=/opt/arm-gdb
--target=arm-elf --host=i686-pc-linux-gnu" which completed without any
errors.
when i do a make, this is what i get..

Configuring in libiberty
configure: loading cache ./config.cache
configure: error: `target_alias' has changed since the previous run:
configure:   former value:  i686-pc-linux-gnu
configure:   current value: arm-elf
configure: error: changes in the environment can compromise the build
configure: error: run `make distclean' and/or `rm ./config.cache' and
start overmake: *** [configure-libiberty] Error 1

how can i fix this? make distclean and rm ./config.cache doesn't help.
on redoing make, i get the same error..

thanks

Re: SIGTRAP error

[Rohit Agarwal]

Thanks a lot Daniel,
that worked.
so finally, i did 

./configure --prefix=/opt/arm-gdb --target=arm-elf --host=i686-pc-linux-gnu
make
make install

it got installed in /opt/arm-gdb

when i invoked gdb from /opt/arm-gdb/bin/arm-elf-gdb i got the folowing result

[root@mahesh bin]# ./arm-elf-gdb -nw

However if i run arm-elf-gdb version 5.3, atleast the load is
complete, although for executing, i get the same problem.

Can anyone suggest what the error is?

Please try CVS, not 6.3.  Load was broken in 6.3.

You also need to apply gdb-6.3-load-remote-target-bug.patch. This is
what PR1944 is fixing.
