我从http://www.netgull.com/gcc/releases/gcc-4.5.0/下载了GCC 4.5,但是当我尝试设置/构建时,我收到以下错误:

configure: error: Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations.  Source code for these libraries can be found at
their respective hosting sites as well as at
ftp://gcc.gnu.org/pub/gcc/infrastructure/.  See also
http://gcc.gnu.org/install/prerequisites.html for additional info.  If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files.  They may be located in separate packages.

以下库存在各自的目录中

/usr/lib/libgmp.a
/usr/lib64/libgmp.a

/usr/lib/libmpfr.a
/usr/lib64/libmpfr.a

我没有在盒子里的任何地方安装libmpc.a库 .

根据错误我怎么知道:

a)安装了当前版本的libgmp.a和libmpfr.a是什么 .

b)如果它们的版本不正确,我如何在不打扰当前版本的情况下部署我自己的版本?

    在我安装了这些库的目录中( /usr/gnu64/lib ),我还有一个 libgmp.la 文件(和 libmpc.lalibmpfr.la 文件),其中包含可读文本 . SO版本信息在那里,但这与'product version'不完全相同 . 它告诉链接兼容性 .

    我试图调查我的版本,我想出的奇怪的解决方案是运行我用 -v 选项构建的GCC(4.6.1) . 在某种程度上,它说:

    GNU C (GCC) version 4.6.1 (x86_64-apple-darwin11.1.0)
        compiled by GNU C version 4.6.1, GMP version 5.0.1, MPFR version 3.0.0, MPC version 0.8.2
    warning: GMP header version 5.0.1 differs from library version 5.0.2.
    warning: MPFR header version 3.0.0 differs from library version 3.1.0.
    warning: MPC header version 0.8.2 differs from library version 0.9.
    

    所以,似乎我安装了GMP 5.0.2(但我用5.0.1构建了GCC)和MPFR 3.1.0(但是我用3.0.0构建了GCC)和MPC 0.9(但我用0.8.2构建了GCC) ) . 不匹配的原因在于我试图编译和安装GCC 4.6.2并且它可能需要更新的版本 . (我没有成功,但这是一个不同的故事 . )

    我在 /usr/gnu64/lib 中安装了我自定义的库,然后通过配置选项 --with-mpfr=/usr/gnu64/lib--with-gmp=/usr/gnu64/lib--with-mpc=/usr/gnu/64/lib 告诉GCC在哪里找到它们 . 这些路径硬连线到GCC,它可以在那里工作 .

    在gcc目录中,执行以下命令:

    ./contrib/download_prerequisites
    

    在该脚本之后,GMP,MPFR和MPC将可以使用 . 继续 ./configure .

    我在尝试安装/编译GCC 4.8.1时遇到了同样的问题 . 以下是我的解决方法:

    在Debian中,只需运行以下两个命令:

    apt-get install libmpc-dev
    ./configure

    我在编译GCC 4.9分支时遇到了同样的问题 .

    对于基于 Red HatFedora 的系统,请运行以下命令:

    sudo yum install gmp gmp-devel mpfr mpfr-devel libmpc libmpc-devel

    这将为整数,浮点和复数安装GNU多精度(MP)库 .
