Gentlemen,
I would like to use gcc compilers to create a cross-compiler for 68k
targets. I have tried the following procedure without success. Can someone
help me?
Thanks
Edo.
I have the following packages inside a commun folder (Gcc) in my workspace:
gcc-3.1
binutils-2.12.1
newlib-1.10.0
1. I build the binutils: result OK
mkdir -p builds/m68k/binutils-2.12.1
cd builds/m68k/binutils-2.12.1
../../../binutils-2.12.1/configure --target=m68k-rtems \
--prefix=/usr/local/cross/m68k
make
make install
2. I added the path (according to the previous --prefix): result OK
setenv PATH
~/bin/powerpc-apple-darwin:/Users/edo/bin:/usr/local/bin:/usr/bin:/bin:/usr/
local/sbin:/usr/sbin:/sbin:/usr/local/cross/m68k/bin
3. I build the compiler
cd gcc-3.1
ln -s ../newlib-1.10.0/newlib .
ln -s ../newlib-1.10.0/libgloss .
cd ..
cd builds/m68k
mkdir gcc-3.1
cd gcc-3.1
../../../gcc-3.1/configure --target=m68k-rtems \
--prefix=/usr/local/cross/m68k --with-newlib \
--with-gnu-as --with-gnu-ld
THESE STEPS TERMINATE CORRECTLY, BUT ...
make
... WORKS FOR A MOMENT AND IT TERMINATES UNSUCCESSFULLY WITH THE FOLLOWING

Any ideas to procede withou errors?
