lfs 编译错误总结
在编译gcc的时候出现如下情况：
make[4]: Entering directory `/mnt/lfs/sources/gcc-build/gcc'
./xgcc -B./ -B/tools/x86_64-unknown-linux-gnu/bin/ -isystem /tools/x86_64-unknown-linux-gnu/include -isystem /tools/x86_64-unknown-linux-gnu/sys-include -L/mnt/lfs/sources/gcc-build/gcc/../ld -O2 -O2 -g -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -I. -I32 -I../../gcc-4.1.2/gcc -I../../gcc-4.1.2/gcc/32 -I../../gcc-4.1.2/gcc/../include -I../../gcc-4.1.2/gcc/../libcpp/include -m32 -g0 -finhibit-size-directive -fno-inline-functions -fno-exceptions -fno-zero-initialized-in-bss -fno-unit-at-a-time -fno-omit-frame-pointer -fno-asynchronous-unwind-tables \

而我在CC="gcc -B/usr/bin/" ../gcc-4.1.2/configure --prefix=/tools \
--with-local-prefix=/tools --disable-nls --enable-shared \
--enable-languages=c 后面加上--disable-multilib就可以，查看下文档发现--disable-multilib选项是为了编译64位系统，而手把手教你如何建立自己的Linux 系统书上却没有提到，一定要编译64位吗？不知道如何解释，另外在之前的binutils编译过程中make结果中出现诸如Nothing to be done for "...." 虽然没有显示error，但是总感觉有点问题，到后面的话是会出现问题，有些人说只要不报错就继续，我实在是很不解？希望高手能帮忙解惑。。。
