Update 2
I had the SDL backend enabled, like an idiot, so, never mind that one. I managed to get the config files to generate, so I'm going to try to build now.

update:

I'm down to this.

How do I disable Theora, why is OpenAL not finding itself (not that we need it at present, and I would just as well disable that too, and where do I disable eNET, and LATEX?

(Never mind. LATEX was WANT_DOCS.) I added eNET, as I am not sure what config option disables it, and it would be good to have it.

The other errors (above) trouble me, and the generate operation fails. What am I missing at this point???

Also what are these options, and to what are they related:
WANT_MODAUDIO : What is the addon for this? Is this internally supported now?
WANT_MEMFILE : What is this, and what is its addon?

Unless Ag4.4.3 needs LATEX for something, I need to figure out how to disable it.

WANT_PRIMITIVES : Is this the allegro drawing primitives? I have this on, as I expect that is what it means.

--------------

Holy hell, there are a thousand config options in the CMake build. I'm trying to generate for MSVC9. I had to manually add some includes that are not standard on Windows, but the library configuration for MSVC is still specifying headers that DO NOT EXIST for Windows. :p

This is the error log:

What options do I need to enable/disable, and why the flidd are these headers missing? Do I need to specify special include paths for CMake somehow?

I'm getting similar errors trying to generate for MSYS+MinGW:

CMake Error at CMakeLists.txt:714 (message):
Windows port requires DirectInput (not found).

This is my fault for not noticing what GitHub changed on their site this week. The branch control widget no longer works properly on FF32. I love those bastards.

I was building the wrong thing, entirely; however, it was apparently ag5 master, which I'll let you all know, does not compile on MSVC9.

Oh, and FWIW, that guide is what got me through the process in the past. Nicely done. I did have issues static linking when I used MSYS a year back, but that was likely an oversight on my part.

I have MSYS on every Windows laptop, but configuring the proper set of include paths was always a barrel of fun, as MSYS and MinGW use entirely isolated path structures.
