从git构建libopus时，如何解决有关AM_PROG_LIBTOOL的错误？

我已经从git 下载libopus并尝试构建它，但是我得到了，

Updating build configuration files, please wait....
configure.ac:38: warning: macro 'AM_PROG_LIBTOOL' not found in library
configure.ac:38: error: possibly undefined macro: AM_PROG_LIBTOOL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
autoreconf: /usr/bin/autoconf failed with exit status: 1

如何解决此错误？

您需要安装libtool，它提供了必要的宏。在Ubuntu上，

apt-get install libtool
