你系统里没有找到libgmp, libmpfr, libmpc

你系统里没有找到libgmp, libmpfr, libmpc

的确，多谢。

现在在着手GMP MPFR MPC的安装尝试
其中遇到问题了，网上说这三个安装是有步骤的，很感激，我贴在这里，找到不容易，希望对看到人的有所帮
助。

不过现在安装GMP的时候出现了错误：checking for suitable m4... configure: error: No usable m4 in $PATH or /usr/5bin (see config.log for reasons).

搜索说是缺少M4
M4 is not installed.
Solution
Start the Ubuntu software Center and install ""M4"" （see this screenshot）.

M4下载地址：ftp://ftp.gnu.org/gnu/m4/
我也不知道下哪个，现在在尝试，记录一下，我会继续记录下去的，希望能给看到的人予以提示。
多谢 xunxun1982 给予的关注。

大哥们，求助。安装gcc过程中  输入make命令的时候出的错误提示
libgmp, libmpfr, libmpc都已经正确安装了，m4也正确安装了，

啊，这个解决了，网上查资料说不能在原来的gcc目录下直接编译，需要换一个目录，
之前没看懂为什么要另外见一个目录是为了什么。

换了个目录
configure通过
make 到半小时的时候报错

checking for suffix of object files... configure: error: in `/home/lixiaobin/gcc-bulid/i686-pc-linux-gnu/libgcc':

错误提示See `config.log' for more details.  看看你的config.log
不过新手，看不太懂config.log
现在贴出来给大家看看，希望能看懂的同志给指点下，小弟在此谢过了。
