在ubuntu上編譯libzmq時，生成configure和makefile的過程中報錯：

按照網友的建議，
sudo apt install automake libtool m4 autoconf
發現全都安裝了。嘗試其他解決方案:原文鏈接
一般通過apt-get安裝的軟件都會在/usr目錄下，既然提示無法找到AC_PROG_LIBTOOL，那么分析一般有兩個原因：
1.安裝包失敗或者其他原因比如版本問題導致沒有定義AC_PROG_LIBTOOL；
2.尋找路徑有問題。
從這兩點出發，可以在/usr目錄下全局查找AC_PROG_LIBTOOL
可以看到在m4文件中能找到AC_PROG_LIBTOOL，那么就可能是路徑問題；
大多數m4文件都在/usr/share/aclocal/目錄下，但實際上configure的默認aclocal路徑為/usr/local/share/aclocal，
那么可以有兩種方法，
第一，將/usr/share/aclocal/下的*.m4文件都拷貝到usr/local/share/aclocal/目錄下；
第二，指定aclocal的安裝路徑；
sudo cp /usr/share/aclocal/*.m4 /usr/local/share/aclocal/
再次./autogen.sh，就通過了。
