autoconf automake 相关问题

在执行aclocal时，出现如下错误：

configure.ac:31: error: Autoconf version 2.62 or higher is required

/usr/share/aclocal-1.11/init.m4:26: AM_INIT_AUTOMAKE is expanded from...

configure.ac:31: the top level

autom4te: /usr/bin/m4 failed with exit status: 63

aclocal: autom4te failed with exit status: 63

autoreconf: aclocal failed with exit status: 63

系统里安装版本为autoconf-2.61,而且是手动安装的,于是在终端输入

sudo apt-get install autoconf

在从源里安装autoconf-2.68

输入aclocal,报相同错误,

原因：此时系统里装了两套autoconf, 即autoconf-2.61 autoconf-2.68

每次在执行aclocal时，都call autoconf-2.61的工具,即/usr/local/bin/autoconf

解决：进入autoconf-2.61的源码目录,

cd software/autoconf-2.61

执行 sudo make uninstall 

就将安装文件都卸载掉了

重启终端, autoconf -V 

其版本为autoconf-2.68

执行aclocal 

正常
