- Subject: trouble building gcc-3.2 --target=m68k-linux from scratch
I'm attempting to build a m68k-linux compiler from scratch using stock
building with bill Gatliff's script to config the kernel, copy over
the hears, config/binud binutils, config/build gcc-bootstrap...
The kernel headers copy over fine, binutils-builds, and gcc-bootstrap
is configured as:
# This file was generated automatically by configure. Do not edit.
# This directory was configured as follows:
/home/pbarada/work/cvs-wavemark/cross-linux-tools/gcc-3.2/configure --with-gcc-version-trigger=/home/pbarada/work/cvs-wavemark/cross-linux-tools/gcc-3.2/gcc/version.c --host=i686-pc-linux-gnu --target=m68k-linux --prefix=/tmp/junk --enable-languages=c --with-local-prefix=/tmp/junk/m68k-linux --without-headers --with-newlib --disable-shared --verbose --norecursion
# using "mt-frag"
And it fails building gcc/unwind-dw2.c:

/home/pbarada/work/cvs-wavemark/cross-linux-tools/gcc-3.2/gcc/gthr-posix.h:37:21: pthread.h: No such file or directory
Configure created ghtr-default.h with '#include <pthread.h>' since it
found a pthread.h that can be used, but that was by using the *host*
compiler to find a phtreads.h, not the *target* compiler.
Since a stock linux source doesn't have pthread.h in its headers, and
glibc hasn't been built yet, there's no pthread.h that can be used at
If I add --disable-threads to the configure for the bootstrap, it
1) Why does configure think that it has a valid pthreads.h(or that is
should use the host compiler to find one)?
2) Is --disable-threads necessary for the bootstrap step?
All suggestions are appreciated...
