First, some of the code is pretty readable, some is decent, and some is patched up crap. Good luck. ;)
Second, if you want to code anything for Aegisub, you will need to agree to these terms:
1. You will release the patch to the public domain or give its copyright to one of the developers. This is to stop a source file from being owned by too many people. (Exception: MAJOR changes might be accepted under BSD license under your name. Consult the developers)
2. Make SURE it compiles and works fine before submitting to developers.
3. Stick to the coding standards. That is, no GNU-style identing and crap.
Third, this is all available under the BSD license. According to GNU itself, BSD is GPL-compatible, meaning that you can link GPL code to BSD code. Keep in mind, though, that if a source file has mixed BSD and GPL content, it becomes ruled by GPL.
Some notes about the procedure:
All paths should be added to the global msvc settings or you might encounter some problems.
This guide assumes Visual Studio 2003 is used, it might work in other versions but it is guaranteed
to fail with other compilers due to the avisynth dependency.
While you can compile most libraries yourself these instructions will assume you want to
download precompiled versions whenever possible. Also note that in most other cases where
precompiled libraries are available they're unsuitable for use in aegisub.
Building instructions (dependencies):
1. Download and install wxWidgets 2.6.x (www.wxwidgets.org, 2.6.2 used when this guide was written).
Open include\wx\msw\setup.h and set WXWIN_COMPATIBILITY_2_4 to 0 and wxUSE_UNICODE to 1. To compile the libraries
first open the visual studio command prompt and go to build\msw. Run "nmake makefile.vc UNICODE=1 BUILD=debug"
and then "nmake makefile.vc UNICODE=1 BUILD=release" to generate the libraries required for aegisub.
Include:
include
lib\vc_lib\mswu
Libraries:
lib\vc_lib
2. Download and compile freetype2 (www.freetype.org). The easiest way to do this is to open the solution found in
builds\win32\visualc\freetype.sln and then batch build all configurations.
Include:
include
Libraries:
objs
3. Download and compile lua (www.lua.org). This easiest done by copying the contents of include, src/lib and src/lua
to src (overwriting makefiles makes no difference here). Create a new win32 c++ project, select static library,
blank project and uncheck precompiled headers. Add all h and c files in src to the project and set code generation
to multi threaded (debug) dll in the configurations, set the output names to lua50MT(d).lib in the lib directory.
Batch compile.
Include:
include
Libraries:
lib
4. Download and compile portaudio (www.portaudio.com). If you want to compile the directsound version
you need to have the directx9 sdk properly set up before continuing. This process is very similar to lua. First copy
the contents of pa_common to the pa_win_wmme and pa_win_ds dirs. Create a blank project and add all files in pa_win_ds
(for directshow) or in pa_win_wmme (for wmme audio output) to the project. Set the library name to PAStaticDSMT(d).lib
and the output path to lib. Set the code generation to multi threaded (debug) dll and batch compile.
Include:
pa_common
Libraries:
lib
5. OPTIONAL - You can safely skip this step if you don't intend to work on the aspell part of aegisub. It's disabled in
the release builds. Download precompiled libs for aspell (aspell.net/win32/) the current direct link is
