Hello, I tried to compile a native 64bit system for my Sempron64 but failed to compile the cross compiler on my own source-based system, on Ubuntu 64bit (which takes 2h for building insn-attrtab.o), and with several versions of binutils, glibc, newlib, and gcc. I also tried out new binutils and gcc for my build system.
The configure options for all packages were: ./configure --prefix=/opt/cross --target=x86_64-*-linux-gnu -v I tried --with-newlib and --without-headers too. For glibc I used --enable-kernel=2.6 and --with-tls. gcc 4.1.0 showed a small extra error in 'host-i686-pc-linux-gnu/gcc': In file included from ./tm.h:4, from ../.././gcc/genmddeps.c:21: ./options.h:516: error: expected ',' or '}' before '-' token make[2]: *** [build/genmddeps.o] Error 1 make[2]: Leaving directory I changed '-' to '_' and it worked. The next error appeared with all tested versions (down to gcc 3.4.6): <gcc-x.x.x>/host-i686-pc-linux-gnu/gcc/xgcc -B/Archiv/Prozessoren/languages/gcc-4.1.0/host-i686-pc-linux-gnu/gcc/ -B/opt/cross/x86_64-*-linux-gnu/bin/ -B/opt/cross/x86_64-*-linux-gnu/lib/ -isystem /opt/cross/x86_64-*-linux-gnu/include -isystem /opt/cross/x86_64-*-linux-gnu/sys-include -O2 -O2 -DIN_GCC -DCROSS_COMPILE -DNATIVE_CROSS -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I../.././gcc -I../.././gcc/. -I../.././gcc/../include -I../.././gcc/../libcpp/include -fexceptions -fvisibility=hidden -DHIDE_EXPORTS -c ../.././gcc/unwind-dw2.c -o libgcc/./unwind-dw2.o In file included from ./gthr-default.h:1, from ../.././gcc/gthr.h:114, from ../.././gcc/unwind-dw2.c:42: ../.././gcc/gthr-posix.h:43:21: error: pthread.h: No such file or directory ../.././gcc/gthr-posix.h:44:20: error: unistd.h: No such file or directory I was able to solve this by appending -I/opt/cross/include to all xgcc lines in the Makefile in gcc-4.1.0/host-i686-pc-linux-gnu/gcc The next error I can't solve: gcc -DIN_GCC -DCROSS_COMPILE -DNATIVE_CROSS -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wold-style-definition -Wmissing-format-attribute -DHAVE_CONFIG_H -I. -I. -I../.././gcc -I../.././gcc/. -I../.././gcc/../include -I../.././gcc/../libcpp/include \ -DPREFIX=\"/opt/cross\" -DBASEVER="\"4.1.0\"" \ -c ../.././gcc/prefix.c -o prefix.o /tmp/cctd8T18.s: Assembler messages: /tmp/cctd8T18.s:17: Error: suffix or operands invalid for `push' /tmp/cctd8T18.s:52: Error: suffix or operands invalid for `push' /tmp/cctd8T18.s:54: Error: suffix or operands invalid for `push' /tmp/cctd8T18.s:55: Error: suffix or operands invalid for `push' /tmp/cctd8T18.s:75: Error: suffix or operands invalid for `pop' /tmp/cctd8T18.s:76: Error: suffix or operands invalid for `pop' /tmp/cctd8T18.s:77: Error: suffix or operands invalid for `pop' /tmp/cctd8T18.s:82: Error: suffix or operands invalid for `push' /tmp/cctd8T18.s:182: Error: suffix or operands invalid for `push' /tmp/cctd8T18.s:202: Error: suffix or operands invalid for `pop' /tmp/cctd8T18.s:212: Error: suffix or operands invalid for `push' /tmp/cctd8T18.s:214: Error: suffix or operands invalid for `push' /tmp/cctd8T18.s:412: Error: suffix or operands invalid for `pop' /tmp/cctd8T18.s:413: Error: suffix or operands invalid for `pop' /tmp/cctd8T18.s:419: Error: suffix or operands invalid for `push' make[2]: *** [prefix.o] Error 1 make[2]: Leaving directory <gcc-x.x.x>host-i686-pc-linux-gnu/gcc' make[1]: *** [all-gcc] Error 2 make[1]: Leaving directory Can you help further?
