[LinuxPPC] cross compiler, compiling

[LinuxPPC] cross compiler, compiling

[Trevor Woerner]

Dear Friends,

following is a log i created for myself while compiling a powerpc
cross compiler on an i586. i used:

   binutils-2.9.1
   egcs-1.1.1
   newlib-1.8.1

also, i was wondering, i compiled newlib (as indicated above) but
i was wondering if i should also compile glib for this cross compiler?
if i did compile both wouldn't the second one overwrite the files
from the first one?

i know you're all rather busy, but could someone *please* comment
on the errors, especially the last (fourth) one.

here's the log:

would it be enough to say:

  target=powerpc-linux
  prefix=/usr/local/ppc
  includes=/usr/local/ppc/linuxppc-includes/
  libraries=/usr/local/ppc/linuxppc-lib
  cpu=603e

  root# ../egcs-1.1.1/configure --target=$target --prefix=$prefix \
        --enable-shared --enable-haifa --with-gnu-as --with-gnu-ld \
        --with-headers=$includes --with-libs=$libraries --with-newlib \
        --with-cpu=$cpu -v &> configure.log

for the includes i went to my LinuxPPC installation and took everything
from /usr/includes, resolved all links and removed obvious stuff like
X11, for the libs i took everything from /lib and /usr/lib, resolved
all references (which were almost always from /usr/lib to /lib) but
preserved the shared-library version links.

does that help? oh by the way my LinuxPPC kernel was compiled from the
Linux 2.2.1 sources. previous to doing this i had recompiled egcs 1.1.1
and binutils 2.9.1-19b on my x86; on the ppc i just installed the rpms
from Gary Thomas.

please don't hesitate to mention if i forgot anything else.

best regards,
   trevor woerner

	Without describing the directory structure for the cross-tools
source and how it was configured, it is hard to diagnose what might be
wrong.

Re: [LinuxPPC] cross compiler, compiling

[David Edelsohn]

	Did you combine egcs, binutils, and newlib directories together?
You should not use newlib if you are intending to create a LinuxPPC
cross-compiler.  You need to point the configuration at the LinuxPPC
headers and libraries.

Re: [LinuxPPC] cross compiler, compiling

[puetzk6715]

Yes - if you're building to LInuxPPC R4, you need to use Gary's SRPMS to
build the cross-compiler, to get fixes for some glibc-1.99 oddity's.

At leat, I htink this is still needed.
