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.

lua编译报错

gcc -std=gnu99 -O2 -Wall -Wextra -DLUA_COMPAT_5_2 -DLUA_USE_LINUX    -c -o lua.o lua.c
lua.c:82:31: fatal error: readline/readline.h: 没有那个文件或目录
compilation terminated.
<builtin>: recipe for target 'lua.o' failed
make[2]: *** [lua.o] Error 1

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

ctrl+c退出解释环境

~$ lua

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
