I've been following the CrossGCC faq to build sh4 versions of binutils, gcc et all and have a failing gcc build which I can't figure out. I built binutils ok with this: # Tree root is the top of our source tree export TREE_ROOT=`pwd`/../.. cd binutils-2.11.2 (cd gas && autoconf) (cd bfd && autoconf) mkdir objdir cd objdir export CFLAGS="-g -O2" export CC=gcc # configure (prefix needs to be calculated) ../configure --target=sh4-linux --prefix=$TREE_ROOT/host/ --program-prefix=sh4-linux- # build, hardwireing the Library path make LIB_PATH=$TREE_ROOT/target/usr/local/lib/:$TREE_ROOT/target/lib:$TREE_ROOT/target/usr/lib/ # install it - paths should be set by configure et all make install And then built gcc using the following: # Tree root is the top of our source tree export TREE_ROOT=`pwd`/../.. cd gcc-3.0.3 (cd gcc; autoconf) rm -rf objdir mkdir objdir cd objdir mkdir gcc cd gcc ln -s $TREE_ROOT/host/bin/sh4-linux-as as cd .. export CFLAGS="-g -O2" # configure (prefix needs to be calculated) ../configure --target=sh4-linux \ --prefix=$TREE_ROOT/host/ \ --program-prefix=sh4-linux- \ --program-transform-name=s,^,sh4-linux-, \ --enable-cross \ --enable-shared \ --enable-languages=c,c++ \ --enable-threads \ --disable-c99 \ --with-system-zlib # build make (cd gcc ; make relocation) # install it - paths should be set by configure et all make install But the build fails with: <snip> if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi ./xgcc -B./

[libgcc/./unwind-dw2.o] Error 1 make[1]: Leaving directory `/home/alex/src/src/gcc/gcc-3.0.3/objdir/gcc' make: *** [libgcc.a] Error 2 I've seen one comment searching google but it was refering to building newlib/glibc and I haven't got to that stage yet. Should all of gcc's build headers be self contained or do I need some external headers to get it to build correctly? p.s. Is there a proper homepage for CrossGCC, I had to guess the email address of the list as the FAQ pages still refer to soureware.cygnus.com -- Alex Bennee Senior Hacker, Braddahead Ltd The above is probably my personal opinion and may not be that of my employer ------ Want more information?
