1、lua5.3.1源码下载与打补丁
参考：http://linuxfromscratch.org/blfs/view/7.8/general/lua.html
http://www.lua.org/ftp/lua-5.3.1.tar.gz
打补丁：
源码包解压后，cd lua -5.3.1,
patch -Np1 -i ../lua-5.3.1-shared_library-1.patch &&
sed -i '/#define LUA_ROOT/s:/usr/local/:/usr/:' src/luaconf.h
2、lua5.3.1源码做一个修改，具体如下：
(1) 修改顶层Makefile：
TO_LIB= liblua.a liblua-$V.so
# Convenience platforms targets.
PLATS= aix bsd c89 freebsd generic linux arm-linux macosx mingw posix solaris
(2) 修改src/Makefile:
修改src/Makefile文件
CC= $(CROSS_COMPILE)gcc -march=armv7-a -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a9 --sysroot=/home/imhqq/share/huqiqiao/toolchain/sysroots/cortexa9hf-neon-poky-linux-gnueabi
LUA_SO= liblua-$V.so
AR= $(CROSS_COMPILE)ar rcu
RANLIB= $(CROSS_COMPILE)ranlib
MYCFLAGS=-I/home/imhqq/share/huqiqiao/nfs_new/usr/include
LUA_SO= liblua-$V.so
还有，和顶层Makefile一样PLATS变量里加入 arm-linux
PLATS= aix bsd c89 freebsd generic linux arm-linux macosx mingw posix solaris
targets里加入arm-linux平台的编译命令.
arm-linux:
$(MAKE) $(ALL) CC="arm-poky-linux-gnueabi-gcc -march=armv7-a -mfpu=neon -mfloat-abi=hard -mcpu=cortex-a9 --sysroot=/home/imhqq/share/huqiqiao/toolchain/sysroots/cortexa9hf-neon-poky-linux-gnueabi" AR="arm-poky-linux-gnueabi-ar rcu" RANLIB="arm-poky-linux-gnueabi-ranlib" \
SYSCFLAGS="-DLUA_USE_LINUX -DLUA_USE_ARM_LINUX" SYSLIBS="-Wl,-E -ldl"
此处自己加了一个编译开关LUA_ARM_LINUX,目的是去掉readline头文件。
（3）修改src/luaconf.h文件：
#if defined(LUA_USE_LINUX)
#define LUA_USE_POSIX
#define LUA_USE_DLOPEN /* needs an extra library: -ldl */
#if !defined(LUA_USE_ARM_LINUX)
#define LUA_USE_READLINE /* needs some extra libraries */
#endif
#endif
3、配置好交叉编译环境变量，再在顶层目录执行 make arm-linux 编译。

原因分析：
找不到string.h头文件。
解决办法：
在src/Makefile中修改：
MYCFLAGS=-I/home/imhqq/share/huqiqiao/nfs_new/usr/include
再执行make arm-linux，编译成功。
3.2 修改顶层Makefile，
INSTALL_TOP= /home/imhqq/share/huqiqiao/vlc-2.2.1-plugin/lib/lua
make install OK. 编译出来的lua安装到了/home/imhqq/share/huqiqiao/vlc-2.2.1-plugin/lib/lua路径下。
