Hi, I am facing problem while building cross compiler gcc-3.4.4 for MIPSEL with --enable-thread option. I get following error message: In file included from ../../gcc-3.4.4/gcc/crtstuff.c:62: ../../gcc-3.4.4/gcc/tsystem.h:79:19: stdio.h: No such file or directory ../../gcc-3.4.4/gcc/tsystem.h:82:23: sys/types.h: No such file or directory ../../gcc-3.4.4/gcc/tsystem.h:85:19: errno.h: No such file or directory ../../gcc-3.4.4/gcc/tsystem.h:92:20: string.h: No such file or directory ../../gcc-3.4.4/gcc/tsystem.h:93:20: stdlib.h: No such file or directory ../../gcc-3.4.4/gcc/tsystem.h:94:20: unistd.h: No such file or directory ../../gcc-3.4.4/gcc/tsystem.h:100:18: time.h: No such file or directory make[1]: *** [crtbegin.o] Error 1 make[1]: *** Waiting for unfinished jobs.... make[1]: Leaving directory `/tmp/mipsel-unknown-linux-gnu-toolchain/build-gcc-bootstrap/gcc' make: *** [all-gcc] Error 2 My config options is as below: ../gcc-3.4.4/configure --target=$TARGET --prefix=$PREFIX --enable-language=c --with-headers=/home/hda7/linux-malta/include --with-gnu-ld --with-gnu-as --disable-shared --enable-threads Can anyone please help me point out the problem cause?
