Hello everyone, I tentatively added configure option "--with-gxx-include-dir=/gnutools-sh/sh-elf/include" in configure command. But ended up also in Segmentation failed,although compile-failed file was different. I earnestly like to use the latest gcc version. Is it impossible to configure sh-elf toolchain from gcc 4.4.0 ? --- Source --- binutils-2.19.1.tar.bz2 gcc-4.4.0.tar.bz2 newlib-1.17.0.tar.gz --- configure command export TARGET=sh-elf export PREFIX=/gnutools-sh /src/gcc-4.4.0/configure --target=$TARGET --prefix=$PREFIX --enable-languages=c,c++ --with-gnu-as --with-gnu-ld --with-newlib --with-gxx-include-dir=/gnutools-sh/sh-elf/include -v 2>&1 | tee configgcc.out make -w all install 2>&1 | tee makegcc.txt --- error /tmp/build/build_gcc/./gcc/xgcc -B/tmp/build/build_gcc/./gcc/ -nostdinc -B/tmp/build/build_gcc/sh-elf/newlib/ -isystem / tmp/build/build_gcc/sh-elf/newlib/targ-include -isystem /src/gcc-4.4.0/newlib/libc/include -B/gnutools-sh/sh-elf/bin/ -B /gnutools-sh/sh-elf/lib/ -isystem /gnutools-sh/sh-elf/include -isystem /gnutools-sh/sh-elf/sys-include -g -O2 -m2a -O2 -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wcast-qu al -Wold-style-definition -isystem ./include -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I../. ./.././gcc -I/src/gcc-4.4.0/libgcc -I/src/gcc-4.4.0/libgcc/. -I/src/gcc-4.4.0/libgcc/../gcc -I/src/gcc-4.4.0/libgcc/../i nclude -DHAVE_CC_TLS -o _pack_sf.o -MT _pack_sf.o -MD -MP -MF _pack_sf.dep -DFINE_GRAINED_LIBRARIES -DL_pack_sf -c ../. ./.././gcc/fp-bit.c /tmp/build/build_gcc/./gcc/xgcc -B/tmp/build/build_gcc/./gcc/ -nostdinc -B/tmp/build/build_gcc/sh-elf/newlib/ -isystem / tmp/build/build_gcc/sh-elf/newlib/targ-include -isystem /src/gcc-4.4.0/newlib/libc/include -B/gnutools-sh/sh-elf/bin/ -B /gnutools-sh/sh-elf/lib/ -isystem /gnutools-sh/sh-elf/include -isystem /gnutools-sh/sh-elf/sys-include -g -O2 -m2a -O2 -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wcast-qu al -Wold-style-definition -isystem ./include -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I../. ./.././gcc -I/src/gcc-4.4.0/libgcc -I/src/gcc-4.4.0/libgcc/. -I/src/gcc-4.4.0/libgcc/../gcc -I/src/gcc-4.4.0/libgcc/../i nclude -DHAVE_CC_TLS -o _unpack_sf.o -MT _unpack_sf.o -MD -MP -MF _unpack_sf.dep -DFINE_GRAINED_LIBRARIES -DL_unpack_sf -c ../../.././gcc/fp-bit.c /tmp/build/build_gcc/./gcc/xgcc -B/tmp/build/build_gcc/./gcc/ -nostdinc -B/tmp/build/build_gcc/sh-elf/newlib/ -isystem / tmp/build/build_gcc/sh-elf/newlib/targ-include -isystem /src/gcc-4.4.0/newlib/libc/include -B/gnutools-sh/sh-elf/bin/ -B /gnutools-sh/sh-elf/lib/ -isystem /gnutools-sh/sh-elf/include -isystem /gnutools-sh/sh-elf/sys-include -g -O2 -m2a -O2 -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wcast-qu al -Wold-style-definition -isystem ./include -g -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc -I. -I. -I../. ./.././gcc -I/src/gcc-4.4.0/libgcc -I/src/gcc-4.4.0/libgcc/. -I/src/gcc-4.4.0/libgcc/../gcc -I/src/gcc-4.4.0/libgcc/../i nclude -DHAVE_CC_TLS -o _addsub_sf.o -MT _addsub_sf.o -MD -MP -MF _addsub_sf.dep -DFINE_GRAINED_LIBRARIES -DL_addsub_sf -c ../../.././gcc/fp-bit.c ../../.././gcc/fp-bit.c: In function '_fpadd_parts': ../../.././gcc/fp-bit.c:735: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.
