AS_IF和AC_MSG_ERROR：错误：可能未定义宏

尝试构建libnice-0.1.10时遇到此类错误。对于解决方案，我正在关注possibly undefined macro: AC_MSG_ERROR，但还没有到达那里。AS_IF和AC_MSG_ERROR：错误：可能未定义宏

一些程序版本

uname: 3.5.0-23-generic 
m4: 1.4.16 
automake: 1.14.1 
autoconf: 2.69 
libtoolize: 2.4.2

我还加ACLOCAL_FLAGS = “ - 我/.../share/aclocal” 中的.bashrc。

以下是autogen报告的症状。

非常感谢您的帮助！

您是否安装了['pkg-config']（http://www.freedesktop.org/wiki/Software/pkg-config/）？看看是否存在'/.../share/aclocal/pkg.m4'。不需要设置ACLOCAL_INCLUDE - 该目录已经是autoconf的一部分，并且可能会阻止在libnice m4目录中搜索。 – 2015-02-18 08:26:09

这只是意味着你错过了pkg-config（或者你也许有一个旧版本）。只需下载并安装。

我确定安装了pkg-config，并且在我的系统上有/usr/share/aclocal/pkg.m4。 ACX_PTHREAD（[AC_DEFINE（[HAVE_PTHREAD] ...）。错误是configure.ac:31：错误：可能未定义宏：AC_DEFINE。如果此标记和其他标记合法，请使用m4_pattern_allow。因此可能还有其他原因。 – 2016-12-24 20:01:19

您应该详细介绍导致“pkg-config”是问题的结论的故障排除步骤。 – jww 2018-01-04 11:05:33
