How to build PyGI AIO with Moluccas

Read about Moluccas first, its gcc has experimental CRT targeting for this guide.

MS CRT targeting initially laid by official mingw.org but still far incomplete. At first I thought it would be as easy as set cflag/cxxflag __MSVCRT_VERSION__=0x0900 and add -lmsvcr90 to GCC's specs file, well for a trivial program? yes it can but thats all it can get. As my experiment goes by there are many issues piling up (from incomplete msvcr implib to puzzled LFS/Y3K macros) that forcing me to modify mingw's crt and win32api files to allow a package completely linked to the new msvcrt dll. In the end I decided to add new GCC flags to simplify this: -vcr70 to -vcr110. The flags correspond msvcrt redist version bundled by each release of Visual C++. Even today it still far from complete.

What it has to do with this guide? there is an article wrote by win32 contributors of Gnome framework (or whatever you called it) that explain the concern. While my approach is far cry in comparison to use real thing (yeah I know MSVC has free express edition) it still useful in some cases at least for OSS zealot (even if they use Windoze).

This guide will focus on latest stable version of GTK-related (should be called GObject-related) libraries as this written. The main packages are Glib 2.38.1 + GTK 3.10.2 + GI 1.38.0 + PyGObject 3.10.1 and we are targeting python 3.3 (which use msvcr100.dll). I must tell you though, there is steady progress to support MSVC from upstream at least for major libraries including GI thingy.

If you don't need CRT targeting, you can use any GCC of your preference in moluccas by put it into moluccas root then switch over using setgcc [gcc folder name].

Download moluccas 0.8a, you need to download the following packages:

M08.exe
M08-basemsys.7z
M08-basetools.7z
M08-ccomp.7z and newer gcc
M08-tex.7z

1. Saves all of them in the same folder,
2. Run M08.exe and specify install path (it's a portable installation). Click OK. Correction: If you have conemu instance(s) already run you need to quit all before clicking OK, see Maximus comment.
3. The installer dialog will vanish quickly to bootstrap conemu and continue with extraction. Due to the sheer number of files, the extraction (write to harddisk) will be way slower than what the CPU capable of.
4. Once completed, run conemu.exe to start
5. Moluccas will try to detect any presence of Visual C++ and try to integrate the latest version you have. During first run it also initialize Miktex installation
6. In the end conemu panel will bring the <^> prompt
7. Type spawn to start an instance of conemu. The panel will hide and still accessible via systray icon.

I will put latest patches and buildscript at https://github.com/tumagonx/pygi-mingw-patches
