Well, since no one has responded i will answer my own question. Theer are two problems with gcc configuration: 1. --without-headers option is broken so badly that I did not even bother to fix it. Instead I ahve built gclib headers and used them with --with-headers and --disable-shared option to compiler. 2. Solution to header problem uncovered another problem. GCC configuration does not handle --with-newlib option properly. If --with-newlib is used, 'inhibit-libc' should be defined no matter what (at least I understand it this way). Instead, it also makes check for usage of --with-headers option. If --with-headers is used, inhibit_libc is undefined, reagrdless of -with-newlib. At the moment I did a quick hack to always define inhibit-libc when --with-newlib is used. This allowed me to build a bootstrap compiler. I will try to build libraries and then fully blown compiler. I will let all know if there any more problems.

Host is i68, target (for now) is i386. host compiler is GCC 3.2.2 I have built binutils, now I am building the compiler. configure --target=i386-linux --prefix=/home/shared/tools --without-headers --with-newlib --enable-languages=c when making gcc, I am getting an error: --------------- mkdir -p -- libgcc if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi /home/rudolfl/project/ibis/build-tools/gcc-3.4.1/gcc/xgcc -B/home/rudolfl/projec t/ibis/build-tools/gcc-3.4.1/gcc/ -B/home/shared/tools/i386-linux/bin/ -B/home/s hared/tools/i386-linux/lib/ -isystem /home/shared/tools/i386-linux/include -isys tem /home/shared/tools/i386-linux/sys-include -O2 -DIN_GCC -DCROSS_COMPILE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-defi nition -isystem ./include -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FL OAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I. -I./. -I./../include -DL_muldi3 -c . /libgcc2.c -o libgcc/./_muldi3.o In file included from ./tm.h:11, from ./libgcc2.c:43: ./config/i386/linux.h:217:20: signal.h: No such file or directory ./config/i386/linux.h:218:26: sys/ucontext.h: No such file or directory make[2]: *** [libgcc/./_muldi3.o] Error 1 make[2]: Leaving directory `/home/rudolfl/project/ibis/build-tools/gcc-3.4.1/gcc ' make[1]: *** [libgcc.a] Error 2 make[1]: Leaving directory `/home/rudolfl/project/ibis/build-tools/gcc-3.4.1/gcc ' make: *** [all-gcc] Error 2 --------------------------------------------- Relevant headers were copied into /home/shared/i386-linux/include Header files were copied from kernel 2.6.7.

Is it a bug or I am doing something wrong? Thanks, /*******************************************************/ Rudolf Ladyzhenskii Senior Design Engineer Open Networks Pty. Ltd.
