报错"configure.ac: error: possibly undefined macro"的解决方案

在ubuntu上编译libzmq时，生成configure和makefile的过程中报错：

libzmq-master$ ./autogen.sh

按照网友的建议，

sudo apt install automake libtool m4 autoconf

发现全都安装了。尝试其他解决方案:原文链接

一般通过apt-get安装的软件都会在/usr目录下，既然提示无法找到AC_PROG_LIBTOOL，那么分析一般有两个原因：

1.安装包失败或者其他原因比如版本问题导致没有定义AC_PROG_LIBTOOL；

2.寻找路径有问题。

从这两点出发，可以在/usr目录下全局查找AC_PROG_LIBTOOL

 

 

可以看到在m4文件中能找到AC_PROG_LIBTOOL，那么就可能是路径问题；

大多数m4文件都在/usr/share/aclocal/目录下，但实际上configure的默认aclocal路径为/usr/local/share/aclocal，
那么可以有两种方法，
第一，将/usr/share/aclocal/下的*.m4文件都拷贝到usr/local/share/aclocal/目录下；
第二，指定aclocal的安装路径；

sudo cp /usr/share/aclocal/*.m4 /usr/local/share/aclocal/

再次./autogen.sh，就通过了。
