autogen.sh失败，输出显示我需要更高版本的autoconf。但实际上我有一个2.6x autoconf ....
为什么它仍然失败？
[mirror@home 4]$ ./autogen.sh
+ autoreconf -i -f -v
autoreconf: Entering directory `.'
autoreconf: configure.in: not using Gettext
autoreconf: running: aclocal --force -I m4
configure.in:4: error: Autoconf version 2.60 or higher is required
configure.in:4: 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
//内容在configure：4中
这是AC_PREREQ（2.60）
[mirror@home 4]$ autoconf
autoconf autoconf2.59 autoconf2.6x
[mirror@home 4]$ autoconf
[mirror@home 4]$ ls -l autocon
[mirror@home 4]$ ls /usr/bin/autoconf* -l
lrwxrwxrwx 1 root root 12 Aug 27 13:55 /usr/bin/autoconf -> autoconf2.6x
-rwxr-xr-x 1 root root 7663 Jan 6 2007 /usr/bin/autoconf2.59
-rwxr-xr-x 1 root root 14635 Feb 3 2011 /usr/bin/autoconf2.6x
2.63> 2.60，但是autogen失败了，这确实令人困惑：(
[mirror@home 4]$ autoconf --version
autoconf (GNU Autoconf) 2.63

我想知道的是为什么autogen.sh失败？
最佳答案
您安装了两个版本的autoconf，并且当aclocal运行autom4te时，这将启动旧版本。您的路径中是否有autom4te-2.6x？如果是这样，请在运行export AUTOM4TE=autom4te2.6x之前设置autoreconf-2.64。
或者只是运行：
AUTOM4TE=autom4te2.6x ./autogen.sh
也可以看看：
update autoconf to at least 2.6
why i failed to build autoconf with autoconf2.6x, its version is newer than 2.6 anyhow
关于centos - 为什么即使使用正确的autoconf，autogen.sh也会失败？，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/12136934/
