Hi, Sorry for the delay in replaying,
You were right if I do sudo I have to export again. I did a sudo bash at the begining and I did not used sudo again. Now the problem is new...
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.
make[1]: *** [configure-target-libmudflap] Error 1
make[1]: Leaving directory `/home/idipous/powerpc/build_gcc'
make: *** [all] Error 2
and for that matter I checked config.log and I saw this:
configure:2320:17: error: gmp.h: No such file or directory
configure: In function 'main':
configure:2324: error: 'choke' undeclared (first use in this function)
configure:2324: error: (Each undeclared identifier is reported only once
configure:2324: error: for each function it appears in.)
configure:2324: error: expected ';' before 'me'
configure: failed program was:
#line 2319 "configure"
#include "confdefs.h"
#include "gmp.h"
int main() {
#if __GNU_MP_VERSION < 3
choke me
#endif
why is this?
any help?
I do not want to build for an Ubuntu powerpc. It is for a university
essay (in order to get my diploma) and I have an embedded powerpc
having Linux 2.2.0.
I think at a later point I will have to download the kernel 2.2.0 and use its headers.
This is a part of what I intend to do but so far I was not able to make the cross compile.

What will be told if you simply write:
sudo powerpc-linux-ar --version
as a command? Is the command found or not after first using the
'export' for redefining PATH?
Usually the $prefix/bin will be puts into the PATH definitions in the
startup-scripts so when opening
a new terminal session the PATH is right and includes ALL the required
search places...

The 'sudo' probably starts a new shell session as 'root', reads the
startup scripts for root and uses the
PATH got from them... And your earlier 'export' command probably was
totally vain and forgotten...
BTW, what is your goal for the $target ? Someone using Ubuntu 7.0.4/x86
or .../x86_64 could
be expected to be interested to crosscompile to Ubuntu 7.0.4/PPC but
your configure command
clearly tells this not being the case at all! A
Ubuntu/x86-X-Ubuntu/PPC cross-GCC build will
succeed in only one build step, producing C/C++/Fortran/Java etc.
compilers and all the shared libs
with threads support etc.
