在javacpp中,编译ffmpeg遇到这样的问题:
。。。。。。。。。。。。
make[1]: Nothing to be done for `all'.
[INSTALL] /root/src/javacpp-presets-master/ffmpeg/cppbuild/linux-x86_64/lib/libvpx.a
[INSTALL] /root/src/javacpp-presets-master/ffmpeg/cppbuild/linux-x86_64/lib/pkgconfig/vpx.pc
make[1]: Nothing to be done for `install'.
ERROR: Xlib 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
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.
Xlib是什么?
