每次只编译一个库的原因，好像是缺少autopoint

root@Ubuntu32:/home/zhangbin/vlc/android/android# sh compile.sh

For an ARMv6 device without FPU, you need a build without FPU:
$ export NO_FPU=1
For an ARMv5 device or the Android emulator, you need an ARMv5 build:
$ export NO_ARMV6=1

If you plan to use a release build, run 'compile.sh release'
VLC source found
Building tools
You are ready to build VLC and its contribs
Building the contribs
Guessing build system... i686-linux-gnu
Creating configuration file... config.mak
Bootstrap completed. 这好像是vlc的bootstrap

Run "make" to start compilation.

Other targets:
* make install same as "make"
* make prebuilt fetch and install prebuilt binaries
* make list list packages
* make fetch fetch required source tarballs
* make fetch-all fetch all source tarballs
* make distclean clean everything and undo bootstrap
* make mostlyclean clean everything except source tarballs
* make clean clean everything
* make package prepare prebuilt packages
make: Nothing to be done for `fetch'.
