cygwin install lua modules

写一篇博客纪念我今天的辛苦工作，虽然最后也不完美，但是这一点工作也许能给大家一点帮助，省得大家再重复走路了。

最近用总用Lua和Cygwin，但Lua用的是LuaForWindows，因此不是原生态的cygwin的东西，其实我很想用cygwin中的Lua，但是cygwin中的lua没有模块啊，都要自己整，想想都觉得费劲。总希望有个人来做这件事，但是今天我终于忍不了了。整了一天，也没有把tecgraf的IUP/IM/CD给整上去，太菜了，没办法，先把整了的东西放上来吧。

安装Cygwin

安装时必须保证安装如下模块：

lua autoconf automake autobuild gcc4 gcc4-g++ wget curl unzip make cmake git libzzip-devel libxml2-devel diff patch libgd-devel libgd2 pkg-config libcurl4 libcurl-devel libsqlite3-devel

安装Lua的模块们

安装了如下模块：

luarocks luazip luaxml lunit luasocket luafilesystem lualogging luadoc md5 date bit32 lpeg luacurl luasql-sqlite3 stdlib lbase64 lpack luaprofiler luagd luacom

安装的步骤有很多，写了3个脚本，生成了一个patch，把这它们下载下来，放到一个文件夹中，切换到那个文件夹，执行 ./install.sh 即可

遇到的问题解释

库路径

cygwin默认安装的Lua，库路径是 /usr/share/lua/5.1 和 /usr/lib/lua/5.1，luarocks编译时应该配置为 ./configure --prefix=/usr

但是在我的电脑上，如果这样做，luarocks在安装其他模块时会提示：

Error: Your user does not have write permissions in /

-- you may want to run as a privileged user or use your local tree with --local.

于是我只好接受默认的/usr/local，这就带来了问题，即后面要修改 LUA_PATH 和 LUA_CPATH，另外cygwin中有些库是.so，有些是.dll，所以cpath比较特殊

luagd Makefile

luagd的Makefile默认是编译不过去的。是因为debian和cygwin的差别造成的。大家看看gd.patch就知道哪里需要改了

卸载

安装完之后要卸载就运行 ./uninstall 即可

临时文件夹

安装时使用了 ~/tmp/luainstall 作为临时文件夹，安装完后并没有删除，如果不想再看到它，请有空删除即可

运行

我只能保证安装没有问题，具体是否能运行，还不知^_^

TODO

IUP或wxLua

Patch：整不明白GUI了，转战 MinGW，参见我的下一篇文章
