gdbserver

gdbserver

[Lanny DeVaney]

I've looked back through the archives and find some references to 
problems configuring and/or building gdbserver for mips-linux.

I'm attempting to build gdb/gdbserver with --target=mips-linux as well, 
using gdb-5.1.1.  Have the earlier issues (they looked to be 1-2 years 
old) been resolved or am I still looking at a "manual build" process? 
 I'm getting lots of errors with the build, although the configure seems 
to go OK.  x86 host, linux-mips target.

Thanks for any help you can provide,

I tried the gdb+dejagnu-20020305 snapshot recently and
both gdb and gdbserver built without problems. IIRC
gdbserver was still broken in gdb-5.1.1.
I haven't used the newly built gdbserver yet, though.

Regards,
Johannes

Thanks.  I used the 20020311 snapshot and it built like a champ.

As Johannes said, use the current CVS snapshot.  MIPS/Linux support for
gdbserver was only contributed about a month ago.  I'd appreciate bug
reports if it does not work for you, especially as I only tested
little-endian.

OK, I'll keep up with it.  I'm doing big-endian.

Anybody had luck with compiling gdbserver for mipsel? I am using x86
based machine running Fedora 2.6.11 kernel, the target device is IDT 434
running Mipsel 2.6.10 kernel. The gcc crosscompiler is mipsel-linux-gcc
and version 3.2.3.

I did a ./configure --host=mipsel-linux-gnu --target=mipsel-linux-gnu
followed by a make. Make failed with the messages:

Perhaps your toolchain is broken, or perhaps you need to configure 
differently.

With my glibc-2.3.3/gcc-3.4.3 toolchain I do:
../gdb-6.6/configure  --target=mipsel-linux --host=mipsel-linux 
--build=i686-pc-linux-gnu

Then make and voila! gdb, gdbserver et al. are built.

It might be the fact that I am trying to compile gdbsever from the
latest version of gdb with older toolchain. I need an upgraded gcc and
glibc but they are also failing to build. Not sure what order I should
compile them ..
