lua 开发环境搭建
参考资料
lua 官网: https://www.lua.org/
luarocks 官网: https://luarocks.org/
linux 下编译Lua源码，同时生成 动态库.so 静态库.a 文件
Linux 基本环境搭建
lua 基本环境
下载 lua
wget https://www.lua.org/ftp/lua-5.4.2.tar.gz
编译 lua
直接 make 即可, 我把编译后的 lua 与 luac 放在了 ~/program/lua/lua542, 然后将这个目录放入 ~/.bashrc 即可
测试 lua
laolang@laolang-mint:lua$ cat hello.lua
print("Hello World")
laolang@laolang-mint:lua$ lua hello.lua
Hello World
laolang@laolang-mint:lua$
luarocks 基本环境
下载 luarocks
wget https://luarocks.org/releases/luarocks-3.11.1.tar.gz
安装 luarocks
解压后执行 ./configure 提示
laolang@laolang-mint:luarocks-3.11.1$ ./configure
Configuring LuaRocks version 3.11.1...
Lua version detected: 5.4
Lua interpreter found: /home/laolang/program/lua/lua542/lua
lua.h for Lua 5.4 not found (tried /home/laolang/program/lua/include/lua/5.4/lua.h /home/laolang/program/lua/include/lua5.4/lua.h /home/laolang/program/lua/include/lua-5.4/lua.h /home/laolang/program/lua/include/lua54/lua.h /home/laolang/program/lua/include/lua.h)
If the development files for Lua (headers and libraries)
are installed in your system, you may need to use the
--with-lua or --with-lua-include flags to specify their location.
If those files are not yet installed, you need to install
them using the appropriate method for your operating system.
Run ./configure --help for details on flags.
configure failed.
laolang@laolang-mint:luarocks-3.11.1$ which lua
/home/laolang/program/lua/lua542/lua
laolang@laolang-mint:luarocks-3.11.1$
根据提示, 将 lua 头文件放入 ~/program/lua/include/lua/5.4 , 然后再次执行 ./configure
lua 头文件

luarocks 安装后的配置
此时直接执行 luarocks 会提示

Variables from the "variables" table of the configuration file can be
overridden with VAR=VALUE assignments.

LUA_INCDIR : (lua.h not found) 看这里看这里看这里看这里看这里

windows 基本环境搭建
lua 基本环境
下载
注意:
需要下载二进制包和源码包
二进制包
https://luabinaries.sourceforge.net/download.html
源码包
https://www.lua.org/ftp/lua-5.4.2.tar.gz
安装
将下载的两个二进制包的内容全部解压到同一个目录, 有提示覆盖, 直接是, 覆盖即可
然后将 lua54.exe 和 lua54c.exe 复制一份并改名, 再将目录添加到 path
测试 lua
E:\code\lua\lua-hello>type main.lua
print("Hello Lua")
E:\code\lua\lua-hello>lua main.lua
Hello Lua
E:\code\lua\lua-hello>
luarocks
下载
http://luarocks.github.io/luarocks/releases/
http://luarocks.github.io/luarocks/releases/luarocks-3.11.1-windows-64.zip
然后将 luarocks 压缩包的内容全部解压到 lua.exe 所在目录

我们需要下载 visual studio 对应的静态库, visual studio 版本与 vc 版本的对应关系
我的是 vs2022 , 所以下载的是 vc17.lib , 下载地址: https://sourceforge.net/projects/luabinaries/files/5.4.2/Windows%20Libraries/Static/
然后我们将静态库复制到 lua.exe 所在目录
再次执行如下命令
luarocks install --tree=rocks luasocket

cmake --build --preset=windows-release # 以及这里

cmake-format -c .cmake-format.py -i CMakeLists.txt
cmake-format -c .cmake-format.py -i src/CMakeLists.txt
cmake-format -c .cmake-format.py -i src/app/CMakeLists.txt
cmake-format -c .cmake-format.py -i src/lua/CMakeLists.txt
需要把上一步编译的 dll 复制到 lib 目录

待完成项
- Makefile 优化
- C++ 与 lua 混编时, 调用 luarocks 安装的依赖的问题
- lua 源码加入到 C++ 工程, 一次性完成编译 lua 库与 C++ lua 混编
