windows编译libiconv和lua-iconv模块

1，安装libiconv

./Configure --prefix=/mybuild --enable-static

image-20200501235612893

make&&make install

[图片上传失败...(image-24114e-1588604171713)]

报错，看来需要指定INSTALLDIR

然而没用，发现上图提示relocatable.c文件有错误，那现在直接去该代码，mmp

image-20200502001250852

将此处INSTALLDIR 改为绝对路径/mybuild，srclib/relocatable.c同样改掉

你m的，终于成功

2,安装lua-iconv模块

set path=%path%;E:\msys64\mingw64\include;E:\msys64\mingw64\lib
luarocks make ICONV=E:\msys64\theIconvDll\bin ICONV_INCDIR=E:\msys64\theIconvDll\include

image-20200502003046172

于是乎，把缺少的dll直接复制到system32文件夹下，然后报如下错误

这里直接搞了半个多小时，最后参考这篇大神的文章得以晓得原因，并解决

解决找不到libiconv_open的问题

看来不能用luarocks工具了，直接gcc分步走编译

E:\msys64\mingw64\bin\gcc.exe -O2 -c -o luaiconv.o -IE:\luajit\src\include luaiconv.c -IE:\msys64\theIconvDll\include -liconv

第二步

gcc.exe -shared -o iconv.dll luaiconv.o -liconv -LE:\msys64\mingw64\include E:\luajit\src\lib/lua51.dll -lm
