I used the freshly installed gcc as the bootstrap compiler this time. But now i get an infininite hang while building libgcc.a (see compile line below). After a little investigation it seems to me that the problem is with the -mcpu=power6 option. The problem seemingly is not the compile line itself (the hang remains when i remove all -mcpu=power6 occurences) but rather the fact, that the freshly generated xgcc was built using this option. Any hints on how to approach this kind of problem? Thanks and best regards Franz My flags where export CC=gcc export CXX=g++ export CPPFLAGS="-D_ALL_SOURCE -I$HOME/soft/include" export CFLAGS="-mcpu=power6 -O2" export BOOT_CFLAGS="$CFLAGS" export BUILD_CFLAGS="$CFLAGS" export STAGE_CFLAGS="$CFLAGS" export STAGE1_CFLAGS="$CFLAGS" export CXXFLAGS="$CFLAGS" export LDFLAGS="-O2 -L$HOME/soft/lib" export MAKE=gmake export CONFIG_SHELL=$HOME/soft/bin/bash export AR_FLAGS=crs export ARFLAGS=crs export PATH=$HOME/soft/gcc4/bin:$PATH And my configure line configure --prefix=/home/feh01589/soft/gcc-4.4.0_stage2 --enable-static --disable-shared --enable-languages=c++ --with-mpfr=/home/feh01589/soft --with-gmp=/home/feh01589/soft --enable-__cxa_atexit --enable-initfini-array --with-libiconv-prefix=/home/feh01589/soft --with-cpu=power6 --disable-bootstrap The problem is the same with and without --disable-bootstrap. I cannot see any effect with --with-cpu=power6 btw (does it have any?). ___________________________________________ Von: Fehringer Franz Gesendet: Dienstag, 16.
