Hello everyone,

I'm trying to build (compile) gcc "core" to make a cross-development platform. My problem is a compilation error in rs6000/linux.h everytime I try to compile gcc. I'm trying to do this on a standard Slackware 9.1, AMD 2500+.

My steps are
compile binutils-2.11.93.0.2 with : "
./configure --prefix=/home/ccool/linuxppc/dev/ --target=powerpc-linux
make
make install (without any problems)
"

and then, I make sure that the tools just build here are in my $PATH with:
"
export PATH=$PATH:/home/ccool/linuxppc/dev/bin
"
the output of "echo $PATH" seems alright : "/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/usr/games:/usr/lib/java/bin:/usr/lib/java/jre/bin:/opt/kde/bin:/usr/lib/qt-3.2.1/bin:/usr/share/texmf/bin:.:/home/ccool/OpenOffice.org1.1.0:/home/ccool/linuxppc/dev/bin "

and then, the fun part begins, I tried theses steps with gcc-3.3.1 and gcc-3.4.0 and gcc-2.95.3
configure with:
"
gcc-3.4.0/configure --target=powerpc-linux --with-newlib --prefix=/home/ccool/linuxppc/dev/
"
and then, I make and here is my errors:

"

if anyone could help me, or tell me where I should look to find an answer. I googled for a few hours to find different ways to build a cross-compiler and they all have similar ways to do it. I also havent any place where this kind of error appears. Maybe there is some libraries that I need !!

Thanks alot

See if this link has your answer
http://gcc.gnu.org/ml/gcc-patches/2001-09/msg00393.html

Would be interested in knowing your results with the new gcc 3.4

Thanks for the tip, I might try it, if I ever find the solution, I'll try to post it.
