ubuntu编译安装lua
安装步骤
- 下载 lua5.3.5
- tar -zxvf lua-5.3.5.tar.gz
- cd lua-5.3.5
- make linux test
- make install # 会安装到系统目录,需要sudo /usr/local/bin
保存一份安装log,以备卸载是找文件. 卸载时删除对应的文件即可
cd src && mkdir -p /usr/local/bin /usr/local/include /usr/local/lib /usr/local/man/man1 /usr/local/share/lua/5.3 /usr/local/lib/lua/5.3
cd src && install -p -m 0755 lua luac /usr/local/bin
cd src && install -p -m 0644 lua.h luaconf.h lualib.h lauxlib.h lua.hpp /usr/local/include
cd src && install -p -m 0644 liblua.a /usr/local/lib
cd doc && install -p -m 0644 lua.1 luac.1 /usr/local/man/man1
安装到其他位置的方法(下面之一)
- make install INSTALL_TOP=/your/prefix/指定安装路径 # 指定安装路径
- make local # 在当前目录下生成 install 目录保存最后的编译结果,copy到需要的位置
如果不打算用源码参与编译,这个源码目录就可以删了.

解决
缺少必要的包,安装下面开发包即可
sudo apt install libreadline-dev
测试lua环境

Ubuntu(16.04)编译安装torch的luajit-rocks
编译torch的 luajit-rocks
安装步骤
git clone https://github.com/torch/luajit-rocks.git
cd luajit-rocks
mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=/your/prefix/表示安装路径
运行解释器时错误
./luajit
./luajit: error while loading shared libraries: libreadline.so.7: cannot open shared object file: No such file or directory
解决
libreadline.so.7对Ubuntu18才有,先用libreadline.so.6顶替一下
cd /lib/x86_64-linux-gnu/
sudo ln -s libreadline.so.6 libreadline.so.7
