在 centos 6.8 中安装最新的 gcc 时出错

Question

我已经遵循HDJEMAI 的建议，但是当我这样做时

./configure --with-system-zlib --disable-multilib --enable-languages=c,c++

有这个错误：

configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ 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.

但是如果我这样做了

sudo yum install libmpc-devel
Loaded plugins: fastestmirror, nvidia, refresh-packagekit
Setting up Install Process
Loading mirror speeds from cached hostfile

 * elrepo: repos.dfw.lax-noc.com

 * rpmforge: mirror.team-cymru.org

No package libmpc-devel available.
Error: Nothing to do

如果我寻找图书馆，我有

ls /usr/lib64/libmp
libmpcdec.so.5        libmpfr.so.1.2.0      libmpssconfig.so
libmpcdec.so.5.0.2    libmp.so              libmpssconfig.so.0
libmpfr.so            libmp.so.3            libmpssconfig.so.0.1
libmpfr.so.1          libmp.so.3.1.14

但请注意，here 中没有 libmpfr.a。在同一个目录中，我有libgmp.so。

如何安装libmpc-devel？那我怎么安装gcc呢？

您应该使用 GCC 源目录中的contrib/download_prerequisites 来下载依赖项的源代码。 GCC 会在构建过程中自动构建和使用它们。
