构建GCC需要GMP 4.2+，MPFR 2.3.1+和MPC 0.8.0+ [英] Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+

问题描述

我从 http://www.netgull.com/下载了GCC 4.5 gcc / releases / gcc-4.5.0 / 但是当我尝试设置/构建时，我得到的错误如下：

试用--with-gmp，--with-mpfr和/或--with-mpc选项来指定
的位置。这些库的源代码可以在
各自的托管站点以及
 ftp://gcc.gnu.org/pub/gcc/infrastructure/中找到。有关其他信息，另请参阅
 http://gcc.gnu.org/install/prerequisites.html。如果
从供应商分发包中获得了GMP，MPFR和/或MPC，则
确保已经安装了库和
文件头。它们可能位于不同的包装中。 
 Linux：>〜/ shared_scripts / bin / gcc / gcc-4.5.0 1041> 
  

以下库位于相应目录中

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

我没有在盒子的任何位置安装libmpc.a库。

基于错误我怎么知道：

a）libgmp.a的当前版本是什么和libmpfr.a被安装。
$ b b）b）如果它们版本不正确，我怎么能部署我自己的版本而不打扰当前版本？

$ b $在安装了这些库的目录（ / usr / gnu64 / lib ）中，我选择了 还有一个 libgmp.la 文件（和 libmpc.la 和 libmpfr.la 文件），其中包含可读的文本。 SO版本信息在那里，但与产品版本不完全相同。它反映了链接兼容性。

我试图调查我的版本，我想出的奇怪解决方案是运行GCC（4.6.1）我用 -v 选项构建。部分地，它说：

  GNU C（GCC）版本4.6.1（x86_64-apple-darwin11.1.0）$ b由GNU C版本4.6.1编译的$ b，GMP版本5.0.1，MPFR版本3.0.0，MPC版本0.8.2 
警告：GMP头版本5.0.1与库版本5.0.2不同。 
警告：MPFR头版本3.0.0与库版本3.1.0不同。 
警告：MPC头版本0.8.2与库版本0.9不同。 
  

所以，看起来我已经安装了GMP 5.0.2（但我用5.0.1构建了GCC ）和MPFR 3.1.0（但我用3.0.0构建了GCC）和MPC 0.9（但我用0.8.2构建了GCC）。这种不匹配是因为我试图编译和安装GCC 4.6.2，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 ，然后告诉GCC使用配置选项 - with-mpfr = / usr / gnu64 / lib ， --with-gmp = / usr / gnu64 / lib ， - with-mpc = / usr / gnu / 64 / lib 。这些路径是硬连线到GCC，它从那里工作。

I downloaded GCC 4.5 from http://www.netgull.com/gcc/releases/gcc-4.5.0/ but when I try to setup / build I am getting below error:

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.
Linux:>~/shared_scripts/bin/gcc/gcc-4.5.0 1041>

The following libs are present in respective directories

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

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

I do not have libmpc.a library installed anywhere in boxes.

Based upon the error how can I know :

a) what is the current version of libgmp.a and libmpfr.a are installed.

b) If they are of incorrect version how can I deploy my own version without disturbing the current one?

解决方案

In the directory where I have those libraries installed (/usr/gnu64/lib), I also have a libgmp.la file (and libmpc.la and libmpfr.la files), which contain readable text. The SO version information is in there, but that is not quite the same as the 'product version'. It tells about link compatibility instead.

I was trying to investigate which version I had, and the weird solution I came up with was to run the GCC (4.6.1) that I built with the -v option. In part, it said:

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.

So, it appears that I have GMP 5.0.2 installed (but I built GCC with 5.0.1), and MPFR 3.1.0 (but I built GCC with 3.0.0) and MPC 0.9 (but I built GCC with 0.8.2). The mismatch comes about because I tried to compile and install GCC 4.6.2 and it presumably needed the newer versions. (I didn't succeed, but that's a different story.)

I install my custom-built libraries in /usr/gnu64/lib, and then tell GCC that's where to find them with the configure options --with-mpfr=/usr/gnu64/lib, --with-gmp=/usr/gnu64/lib, --with-mpc=/usr/gnu/64/lib. These paths are hard-wired into GCC and it works from there.
