GCC升级问题
现在版本为：gcc version 4.1.1 20070105 (Red Hat 4.1.1-52) 我从网站下下了源码编译gcc-4.5.0执行./configure --prefix=/usr/gcc-4.5 --enable-languages=all --with-gmp=/usr/local/gmp --with-mpfr=/usr/local/mpfr --enable-libgomp后
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.
之前先编译了mpfr-2.3.1 和 gmp-4.2.2
请大家指点下，不盛感激。 本帖最后由 prolj 于 2010-05-07 10:41 编辑
mpfr-2.3.1 和 gmp-4.2.2 的 头文件 追加到路径里面，具体问题去这里问，我现在的工作重点在别的上面。

没有编译mpc？ 不可以yum 安装么 远程用yum升级吧 从GCC 4.5开始，除了gmp,mpfr之外，还需要安装mpc库，并用--with-mpc指定。
