LFS第二十一天-再次安装gmp、mpfr、file、gcc

        安装gmp,mpfr,file:

gmp:
        ./configure --prefix=/usr --enable-cxx --enable-mpbsd
        make
        make check 2>&1 | tee gmp-check-log
        awk '/tests passed/{total+=$2} ; END{print total}' gmp-check-log
        make install

        mkdir -v /usr/share/doc/gmp-5.0.0
        cp -v doc/{isa_abi_headache,configuration} doc/*.html \ /usr/share/doc/gmp-5.0.0
mpfr:
        ./configure --prefix=/usr --enable-thread-safe
        make
        make check
        make install
        make html
        mkdir -pv /usr/share/doc/mpfr-2.4.2
        find . -name \*.html -type f -exec cp -v \{} /usr/share/doc/mpfr-2.4.2 \;

file:
        ./configure --prefix=/usr
        make
        make check
        make install

安装gcc:

一些准备工作：
    sed -i 's/install_to_$(INSTALL_DEST) //' libiberty/Makefile.in
    case `uname -m` in
      i?86) sed -i 's/^T_CFLAGS =$/& -fomit-frame-pointer/' \
            gcc/Makefile.in ;;
    esac
    sed -i 's@\./fixinc\.sh@-c true@' gcc/Makefile.in
    sed -i 's/getline/get_line/' libiberty/testsuite/test-demangle.c
    mkdir -pv ../gcc-build
    cd ../gcc-build
配置、编译：
../gcc-4.4.3/configure --prefix=/usr \
    --libexecdir=/usr/lib --enable-shared \
    --enable-threads=posix --enable-__cxa_atexit \
    --enable-clocale=gnu --enable-languages=c,c++ \
    --disable-multilib --disable-bootstrap
make
make check
