我正在尝试使用this为Android编译ffmmpeg，但出现“错误:未找到freetype2”，如下所示。

*****************The error is here*****************
ERROR: freetype2 not found
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
[email protected] mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solving the problem.
我已经安装了freetype，并且还按如下所示在/usr/include/中对其进行了链接
rwxr-xr-x 3 root root 4096 Mar 20 22:13 freetype2
lrwxrwxrwx 1 root root 23 Mar 20 22:14 freetype -> /usr/include/freetype2/
我不确定下一步该怎么做，请您帮忙？
最佳答案
您需要一个为ARM构建的freetype2版本，并且可能在/usr/include下安装的freetype2是为您的PC体系结构构建的。看起来该项目包含一个用于为ARM构建freetype2的配置脚本。如果您使用该脚本构建freetype2并链接至该版本，则此方法应该有效。
