How to build gnu `libiconv` on & for windows?

问题:

I want to build a static library (*.LIB file) GNU libiconv on windows to be used with other libraries in Visual C++. Other libraries I'm using are built with "MultiThreaded DLL" (/MD) Runtime option. So, I need to build libiconv with the same option.

Problem is the libiconv uses GNU build system and I want to compile with /MD option. You can see the source structure of libiconv here:
http://cvs.savannah.gnu.org/viewvc/libiconv/?root=libiconv

Mr. Zlatkovic maintains the windows port of GNU libiconv for libxml2

you can see them here:

ftp://xmlsoft.org/libxml2/win32/iconv-1.9.2.win32.zip

I cannot use his port. I need to build from the latest version of libiconv-1.13. I wonder how this guy has ported it? Can some one please tell me how to build *.lib from this and compile it using MSVC?

EDIT:

Actually, I need to build few more gnu libraries with same settings. So, if I get solution for one library. I can do the same for all others.

I found PARK Youngho's How to Build libiconv with Microsoft Visual Studio over at The Code Project to be complete and clean (for VS2010 and GNU libiconv 1.14).

A little addition to your answer. I had the same issue and found that the MinGW + MSYS solution was perfect.

Though, I needed to go a little further and generate also the .lib file in order to be able to link with the resulting dll.

This is what I found:

• generate a .def file from the dll with dumpbin (a Visual Studio tool).

• generate the .lib file from the .def with the lib program (Visual Studio tool too)

This allows you to specify some link flags if appropriate. Everything detailed here (I'm not the author of this method): http://wiki.videolan.org/GenerateLibFromDll

I also realized that this lib/dll couple can be linked with both MD and MDd libraries.

Hope that can help people that find this post, like it helped me.

compile them using MinGW using Msys for the environment if needed. MinGW's .a files are apparently, according to the mailing list, the same format as .lib files (just do a rename). You might want to check first to see if the iconv static library is included already in the MinGW download / filesystem.

Edit: it's in msys (C:\msys\1.0\lib), along with:

• libiconv.a
• libiconv.dll.a
• libiconv.la

and additionally

• libiconv-2.dll (in C:\msys\1.0\local\bin)

Edit: is it in here, the libiconv you need? these versions seem to have MSVC makefiles :) http://www.opensource.apple.com/source/libiconv/

I'm the OP. MSYS is the exact thing what I was looking for.

Just install MinGW & MSYS which contains shell sh.exe & make.exewith which you can configure and generate a Makefile after that you can use make.exe to run it.

Its as simple as that.
