LFS第五天-gcc安装

        目的：安装gcc

#安装gomp mpfr m4等软件，同样安装在/tools目录下

        安装好之后，发现/tools/lib下会有相关库。

mkdir -v ../gcc-build
cd ../gcc-build
../gcc-4.4.3/configure --target=$LFS_TGT --prefix=/tools --disable-nls --disable-shared --disable-multilib --disable-decimal-float --disable-threads --disable-libmudflap --disable-libssp --disable-libgomp --enable-languages=c --with-gmp=/tools --with-mpfr=/tools

 出现错误：

checking for suffix of object files... configure: error: in `/mnt/lfs/sources/gcc-build/i686-lfs-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile
See `config.log' for more details.

找到相应的config.log:

/mnt/lfs/sources/gcc-build/./gcc/cc1: error while loading shared libraries: libmpfr.so.1: cannot open shared object file: No such file or directory

          libmpfr.so.1很明显是mpfr的库，刚已经安装过了，可是这里为什么找不到啦？为configure加上--with-lib-mpfr和--with-lib-gmp.

rm -rf *
../gcc-4.4.3/configure --target=$LFS_TGT --prefix=/tools --disable-nls --disable-shared --disable-multilib --disable-decimal-float --disable-threads --disable-libmudflap --disable-libssp --disable-libgomp --enable-languages=c --with-gmp=/tools --with-mpfr=/tools --with-lib-gmp=/tools/lib --with-lib-mpfr=/tools/lib

还是同样的错误：

/mnt/lfs/sources/gcc-build/./gcc/cc1: error while loading shared libraries: libmpfr.so.1: cannot open shared object file: No such file or directory

              那么是什么问题拉？
