lua交叉编译

获取源码

curl -R -O http://www.lua.org/ftp/lua-5.3.5.tar.gz
tar zxf lua-5.3.5.tar.gz
cd lua-5.3.5

修改Makefile

修改安装路径

vi Makefile

INSTALL_TOP= /usr/local

改为

INSTALL_TOP= 自定义安装路径

修改编译配置

注意只修改它表明可以修改的位置
vi src/Makefile

安装

修改完成后执行

make linux 
make install

拷贝到开发板上即可

　测试:

开发板上运行

chmod +x lua
./lua -v
echo "print(\"hello lua\")" | ./lua 

注意

make test不能在PC上执行,因为是交叉编译的所以无法执行测试

可能遇到缺少库的问题,不过通常都能在交叉编译器的路径中找到,拷贝到板子上就行
