寫一篇博客紀念我今天的辛苦工作，雖然最后也不完美，但是這一點工作也許能給大家一點幫助，省得大家再重復走路了。

最近用總用Lua和Cygwin，但Lua用的是LuaForWindows，因此不是原生態的cygwin的東西，其實我很想用cygwin中的Lua，但是cygwin中的lua沒有模塊啊，都要自己整，想想都覺得費勁?？傁Ｍ袀€人來做這件事，但是今天我終于忍不了了。整了一天，也沒有把tecgraf的IUP/IM/CD給整上去，太菜了，沒辦法，先把整了的東西放上來吧。

安裝Cygwin

安裝時必須保證安裝如下模塊：

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

安裝Lua的模塊們

安裝了如下模塊：

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

安裝的步驟有很多，寫了3個腳本，生成了一個patch，把這它們下載下來，放到一個文件夾中，切換到那個文件夾，執行 ./install.sh 即可

遇到的問題解釋

庫路徑

cygwin默認安裝的Lua，庫路徑是 /usr/share/lua/5.1 和 /usr/lib/lua/5.1，luarocks編譯時應該配置為 ./configure --prefix=/usr

但是在我的電腦上，如果這樣做，luarocks在安裝其他模塊時會提示：

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.

于是我只好接受默認的/usr/local，這就帶來了問題，即后面要修改 LUA_PATH 和 LUA_CPATH，另外cygwin中有些庫是.so，有些是.dll，所以cpath比較特殊

luagd Makefile

luagd的Makefile默認是編譯不過去的。是因為debian和cygwin的差別造成的。大家看看gd.patch就知道哪里需要改了

卸載

安裝完之后要卸載就運行 ./uninstall 即可

臨時文件夾

安裝時使用了 ~/tmp/luainstall 作為臨時文件夾，安裝完后并沒有刪除，如果不想再看到它，請有空刪除即可

運行

我只能保證安裝沒有問題，具體是否能運行，還不知^_^

TODO

IUP或wxLua

Patch：整不明白GUI了，轉戰 MinGW，參見我的 下一篇文章

cygwin install lua modules
