Cross Compiler selber bauen

Lycanthropist

Hallo Leute!

Ich möchte mir einen ARM Cross-Compiler selber bauen.

Dazu habe ich die binutils mit --target=arm-linux-gnueabi --prefix=/home/lyc/arm/ konfiguriert und installiert. Das war einfach.

Beim GCC habe ich allerdings Probleme. Ich weiß, dass ich zuerst einen Bootstrap-GCC brauche, da ich noch keine libc für das Target habe. Also habe ich den GCC mit --prefix=/home/lyc/arm --target=arm-linux-gnueabi --enable-languages=c --without-headers konfiguriert. Beim kompilieren bekomme ich allerdings den folgenden Fehler:

/home/lyc/arm/src/build-gcc/./gcc/xgcc -B/home/lyc/arm/src/build-gcc/./gcc/ -B/usr/local/arm-linux-gnueabi/bin/ -B/usr/local/arm-linux-gnueabi/lib/ -isystem /usr/local/arm-linux-gnueabi/include -isystem /usr/local/arm-linux-gnueabi/sys-include    -g -O2 -O2  -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE  -W -Wall -Wwrite-strings -Wcast-qual -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition  -isystem ./include  -fPIC -Wno-missing-prototypes -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -fno-stack-protector -Dinhibit_libc  -I. -I. -I../.././gcc -I../../../gcc-4.6.3/libgcc -I../../../gcc-4.6.3/libgcc/. -I../../../gcc-4.6.3/libgcc/../gcc -I../../../gcc-4.6.3/libgcc/../include  -DHAVE_CC_TLS  -o emutls.o -MT emutls.o -MD -MP -MF emutls.dep -fexceptions -c ../../../gcc-4.6.3/libgcc/../gcc/emutls.c -fvisibility=hidden -DHIDE_EXPORTS

Daraufhin habe ich es mit zusätzlich --disable-threads versucht, aber dann bekomme ich statt dessen diesen Fehler:

Kann mir jemand helfen?

Vielen Dank im Voraus!

Um den ganzen Aufwand zu umgehen, arbeite ich mit Atollic TrueSTUDIO. Leider nur Windows.

Für Linux gibt es auch fertige Cross-Compiler. Z.B. bei emdebian. Allerdings bauen die keinen Ada Compiler. Also muss ich den selber bauen.

Ich hab mal in die PKGBUILD aus dem AUR von Archlinux geguckt, die setzen da folegende configure optionen:

cd ${srcdir}/gcc-$pkgver

  export CFLAGS="-O2 -pipe"
  export CXXFLAGS="-O2 -pipe"

 ../configure --prefix=/usr \
	--target=arm-elf \
	--host=$CHOST \
	--build=$CHOST \
        --enable-shared --disable-nls \
        --enable-languages=c,c++ \
        --enable-multilib \
        --enable-interwork \
	--with-local-prefix=/usr/lib/arm-elf \
	--with-as=/usr/bin/arm-elf-as \
        --with-ld=/usr/bin/arm-elf-ld \
	--with-newlib \
        --with-float=soft \
        --with-sysroot=/usr/$CHOST/arm-elf

  make all-gcc all-target-libgcc all-target-libstdc++-v3
