x86(host) --> ppc(tgt) cross-tool-chain

x86(host) --> ppc(tgt) cross-tool-chain

[brian.auld]

Hello,

Using Karim's new book "Building Embedded Linux Systems", has anyone out there successfully built an x86(host) --> ppc(tgt) tool chain using the versions stipulated in the book (gcc 2.95.3, binutils: 2.10.1, glibc, 2.2.1).

If yes:

(a) What host system are you using?

(b) Did you diverge from the directions in the book?

If no:

(a) Can someone out there suggest a known valid combination?


I anticipate needing ssh, some web-server and snmp as application requirements, so I figured it would be prudent to get the tool-chain working with glibc as opposed to uClibc.

BTW, there's an ongoing thread about exactly this problem

Apparently you're not alone ...

I built the toolchain on x86 host for PPC, and I used

GCC-2.95.3
GLIBC-2.2.3
Binutils-2.11.92

I did not use Karim's book. I went with "Embedded Linux Interfacing ...."
book.

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.

I don't know about that book and your specific glibc version,
but earlier versions of glibc (2.1.3) needed a patch to correctly
support powerpc processors with 16-byte cachelines like the 4xx- and
8xx-series.

I've built several cross compilers (for ppc) from scratch for use on
x86-based machines using gcc-2.95.3 and glibc-2.1.3. I have tested
several binutils versions, don't remember all right now, but I think
binutils-2.11.2 worked out ok except for some strip command line problems.

And yes, the toolchain was used with mpc8xx processors.

Small correction, 405EP, 405GP, 405GPr (and probably all other 405 based
CPUs),
440GP, 440GX have _32_ byte cacheline.

To be specific, that's only 403 that has a 16-byte cacheline.

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

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,

Karim

I have Redhat 8.0, which I believe has GCC-3.2
