1. Clone Aegisub's repository recursively to fetch it and all submodules: `git clone --recursive git@github.com:Aegisub/Aegisub.git` This will take quite a while and requires about 2.5 GB of disk space.
You should now have a `bin` directory in your Aegisub directory which contains `aegisub32d.exe`, along with a pile of other files.
The Aegisub installer includes some files not built as part of Aegisub (such as Avisynth and VSFilter), so for a fully functional copy of Aegisub you now need to copy all of the files from an installed copy of Aegisub into your `bin` directory (and don't overwrite any of the files already there).
You'll also either need to copy the `automation` directory into the `bin` directory, or edit your automation search paths to include the `automation` directory in the source tree.
After building the solution once, you'll want to switch to the Debug-MinDep configuration, which skips checking if the dependencies are out of date, as that takes a while.
### OS X
A vaguely recent version of Xcode and the corresponding command-line tools are required.
Nothing older than Xcode 5 has been tested recently, but it is likely that some later versions of Xcode 4 are good enough.
For personal usage, you can use homebrew to install almost all of Aegisub's dependencies:
[ffms2](http://github.com/FFMS/ffms2) currently does not have a homebrew formula, but with ffmpeg installed should be a simple `./configure && make && make install` to install.
Once the dependencies are installed, build Aegisub with `autoreconf && ./configure && make && make osx-bundle`.
`autoreconf` should be skipped if you are building from a source tarball rather than `git`.
