Hi all, I've got a problem in building a cross compiler for an IBM powerpc. I successefully built the binutils (versione 2.13.92) and installed them under the ~/cross_compiler/Sources/install directory. I've then built the glibc 2.3.2 library using a minimal gcc build and installed it under my ~/cross_compiler/Sources/inst_glibc directory. I've finally tried to build the real fully-featured gcc (version 3.3) specifying the new built glibc as target libraries. The process runs for a while but it stops when it checks if the xgcc works. Looking at the ~/cross_compiler/Sources/build-real-gcc/powerpc-linux/libiberty/config.log I've noticed the compiler complain for some missing libraries. This is a snippet of the problem: [lapo@localhost libiberty]$ pwd /home/lapo/cross_compiler/Sources/build-real-gcc/powerpc-linux/libiberty [lapo@localhost libiberty]$ /home/lapo/cross_compiler/Sources/build-real-gcc/gcc/xgcc -B/home/lapo/cross_compiler/Sources/build-real-gcc/gcc/ -B/home/lapo/cross_compiler/Sources/install/powerpc-linux/bin/ -B/home/lapo/cross_compiler/Sources/install/powerpc-linux/lib/ -isystem /home/lapo/cross_compiler/Sources/install/powerpc-linux/include -o conftest -O2 -g -O2 conftest.c Reading specs from /home/lapo/cross_compiler/Sources/build-real-gcc/gcc/specs Configured with: ../gcc-3.3/configure --prefix=/home/lapo/cross_compiler/Sources/install --target=powerpc-linux --with-local-prefix=/home/lapo/cross_compiler/Sources/install --enable-thread=posix --with-gnu-as --with-gnu-ld --with-as=/home/lapo/cross_compiler/Sources/install/bin/powerpc-linux-as --with-ld=/home/lapo/cross_compiler/Sources/install/bin/powerpc-linux-ld --enable-languages=c,c++ --with-cpu=powerpc --with-sysroot=/home/lapo/cross_compiler/Sources/inst_glib --with-headers=/home/lapo/cross_compiler/Sources/inst_glib/include --with-libs=/home/lapo/cross_compiler/Sources/inst_glib/lib Thread model: posix gcc version 3.3 /home/lapo/cross_compiler/Sources/build-real-gcc/gcc/cc1 -quiet -v -iprefix /home/lapo/cross_compiler/Sources/build-real-gcc/gcc/../lib/gcc-lib/powerpc-linux/3.3/ -isystem /home/lapo/cross_compiler/Sources/build-real-gcc/gcc/include -isystem /home/lapo/cross_compiler/Sources/install/powerpc-linux/bin/include -isystem /home/lapo/cross_compiler/Sources/install/powerpc-linux/lib/include -D__GNUC__=3 -D__GNUC_MINOR__=3 -D__GNUC_PATCHLEVEL__=0 -D__unix__ -D__gnu_linux__ -D__linux__ -Dunix -D__unix -Dlinux -D__linux -Asystem=unix -Asystem=posix -isystem /home/lapo/cross_compiler/Sources/install/powerpc-linux/include conftest.c -quiet -dumpbase conftest.c -auxbase conftest -g -O2 -O2 -version -o /home/lapo/tmp/ccqQ4Fzu.s ignoring nonexistent directory "/home/lapo/cross_compiler/Sources/install/powerpc-linux/bin/include" ignoring nonexistent directory "/home/lapo/cross_compiler/Sources/install/powerpc-linux/lib/include" ignoring nonexistent directory "/home/lapo/cross_compiler/Sources/install/powerpc-linux/include" GNU C version 3.3 (powerpc-linux) compiled by GNU C version 3.2.2 (Mandrake Linux 9.1 3.2.2-3mdk).
