建立GCC需要GMP 4.2 +,MP​​FR 2.3.1+和MPC 0.8.0+

Question

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

我没有在框中的任何地方安装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.

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？

Answer 1

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.

Answer 2

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

Answer 3

我在编译GCC 4.9分支时遇到了同样的问题.

对于基于Red Hat和Fedora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.

Answer 4

在我安装了这些库的目录(/usr/gnu64/lib)中,我还有一个包含可读文本的libgmp.la文件(libmpc.la和libmpfr.la文件).SO版本信息在那里,但这与"产品版本"不完全相同.它告诉链接兼容性.

我试图调查我的版本,我想出的奇怪解决方案是运行我用该-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.

因此,似乎我安装了GMP 5.0.2(但我用5.0.1构建了GCC),MPFR 3.1.0(但我用3.0.0构建了GCC)和MPC 0.9(但是我用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.)

我安装在我的定制库/usr/gnu64/lib,然后告诉GCC这就是与配置选项找到它们--with-mpfr=/usr/gnu64/lib,--with-gmp=/usr/gnu64/lib,--with-mpc=/usr/gnu/64/lib.这些路径硬连接到GCC,它可以在那里工作.
