centos - 为什么 autogen.sh 即使使用正确的 autoconf 也会失败？

Question

autogen.sh 失败，输出显示我需要更高版本的 autoconf。但事实上我有一个 2.6x autoconf....

为什么还是失败了？

[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

//配置中的内容:4
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，真的很迷惑:(

我想知道为什么autogen.sh失败了？

您安装了两个版本的 autoconf，当 aclocal 运行 autom4te 时，将启动旧版本。你的路径中有 autom4te-2.6x 吗？如果是这样，请在运行 autoreconf-2.64 之前设置 export AUTOM4TE=autom4te2.6x。

或者只是运行:

AUTOM4TE=autom4te2.6x ./autogen.sh

另见:

update autoconf to at least 2.6

why i failed to build autoconf with autoconf2.6x, its version is newer than 2.6 anyhow
