Yes, it does work. I have a small web server running with glibc-2.2.3.

:)

I have to ask: Did this toolchain actually work for you on the target?
I mean, did you try using glibc-2.2.3 on the PPC target? From I've
seen, gcc 2.95.3 with glibc 2.2.3 will successfully generate a glibc,
but the resulting glibc will core dump on the target.

gdb configuration for powerpc target on pentium pc

[dong in kang]

 I'm trying to debug Linux kernel on the Sandpoint X3 with MPC755 CPU board.
I'm using BDI 2000 with GDB.
I configured gdb v.5.3 as follows

  configure --prefix=/usr/local/cross-ppc/host/intel/ --target=powerpc-linux


 While I used the gdb with BDI, the breakpoints set by gdb do not work well.
It doesn't stop.
After a while, I typed Ctrl-C to stop it. Then it shows the messages shown
below.
And then it terminates. Could it be GDB configuration problem?
Has anybody got similar problem?

 Thanks in advance.

It seems the success with a toolchain component version set depends on the
native tools you have on your workstation. Can you tell me what distro
you were using on your workstation when you built glibc 2.2.3 in the
above setup.

Thanks,
