编译 lua 的时候报错头文件找不到：

解决方法

# centos
yum install readline-devel
# debian
apt-get install libreadline-dev.

# centos

yum install readline-devel

# debian

apt-get install libreadline-dev.

一、安装

wget https://www.lua.org/ftp/lua-5.3.4.tar.gz
tar -zxvf lua-5.3.4.tar.gz
cd lua-5.3.4
make linux test
make install

wget https://www.lua.org/ftp/lua-5.3.4.tar.gz

tar -zxvf lua-5.3.4.tar.gz

cd lua-5.3.4

make linux test

make install

一、 luaL_dofile(): cannot open ./lib.lua: No such file or directory

问题原因

运行应用的目录和 lua 文件不在同一个目录，.lua 文件所在的目录是当前所在的目录而不是程序所在目录。

ma@ubuntu:/data/code/lua/2-lua 和 c++/cpp-lua$ tree
.
├── debug
│   └── app
├── lib.lua
├── main.cpp
└── Makefile

1 directory, 6 files

ma@ubuntu:/data/code/lua/2-lua 和 c++/cpp-lua$ tree

├── debug

│ └── app

├── lib.lua

├── main.cpp

└── Makefile

1 directory, 6 files

app 在当前目录下的 debug 目录下，在当前目录下执行./debug/app 可以成功读取到 lib.lua，但是在 debug 目录下执行./app 就会报错。

一、安装 Lua 和 LuaJIT

LuaJIT 下载页面：luajit.org，Lua 下载页面：lua.org 。

1.1 安装 lua

wget https://www.lua.org/ftp/lua-5.3.4.tar.gz
tar -zxvf lua-5.3.4.tar.gz
cd lua
make linux test
make install

wget https://www.lua.org/ftp/lua-5.3.4.tar.gz

tar -zxvf lua-5.3.4.tar.gz

cd lua
