`-static-libgcc -static-libstdc++` is all you need with regular MinGW.

Note: I don't even build my libraries with those switches, just the game.

Thanks Michal. I tested it and it works great. Just had to link openal and libwinmm.a which seemed to be unnecessary in 5.0.6, but everything is working nicely again.

Thanks Michal for MSVC2010 version!

Here's a contribution from me.

Allegro 5.0.10 - Compiled CHM API reference
https://www.dropbox.com/s/8oazl79tyfoad6n/allegro-5.0.10-doc.7z

Enjoy!

If someone is looking for GCC for windows there is one up to date version prepared by Stephan T. Lavavej there. It is up to date in order to test newest C++ features.

Well you have HTML Help Workshop which is free, it's not that difficult to understand. You have a HHP file which is a project file, HHC is a content file and there is also an index file which is not required, but helpful.

Here's what I've done.

1. Download the whole API reference from allegro site using wget - you can get it for windows here - http://downloads.sourceforge.net/gnuwin32/wget-1.11.4-1-setup.exe
I've used this commad:
wget.exe --recursive --no-clobber --page-requisites --html-extension --convert-links --restrict-file-names=windows --domains alleg.sourceforge.net --no-parent alleg.sourceforge.net/a5docs/5.0.10

After it's finished it will create folder structure:
alleg.sourceforge.net/a5docs/5.0.10

You can stop here if you don't need the CHM version. HTML files work okay.

Then I've made a simple ruby script for making HHP, HHC and index files so that I don't have to add all of those content file index and stuff by myself, you can get it here:
https://www.dropbox.com/s/2tn6j5pv8unz6n5/generateHHP.7z

You put it inside:
alleg.sourceforge.net/a5docs/

And run it, enter folder name, which in this case is 5.0.10 and it will generate HHP, HHC and index files in it. It will also remove searchbox from all html files because javascript doesn't work very well in CHM.

After that you just run the chmproject.hhp file and compile the file which should be saved inside:
alleg.sourceforge.net/a5docs/

And that's it.

Also here's 5.1.8 - Compiled CHM api:
https://www.dropbox.com/s/3lka1o1xzwr0cxg/allegro-5.1.8-doc.7z

Haven't really looked at it. I see it now.

You can skip the download step and put the contents of generateHHP.7z into docs/html of allegro source.

Run generateHHP.bat and enter refman as folder name.

Rest is the same.

HTML Help Workshop is available here - http://go.microsoft.com/fwlink/?LinkId=14188

EDIT:

I've made a batch script which automatically generates necessary files and compiles CHM file.

All you need to do is to put the contents into docs/html of allegro source run generateCHM.bat and press Enter to begin.

Get it here:
https://www.dropbox.com/s/93queu1a4nvv4wc/generateCHM.7z

Please note that HTML Help Workshop needs to be installed for this to work. This script will look for it in Program Files directory.

You can use standard MSVC2012 version for that, it's the same - http://targonski.nazwa.pl/thedmd/allegro/5.0.10/allegro-5.0.10-msvc-11.0.7z

I will look at XP compatible build on Friday or Saturday.

Hmm you might be missing something here. I've tried compiling my project in MSVC2012 with Visual Studio 2012 - Windows XP (v110_xp) toolset and it compiled without any problems.

Again, I used this version - http://targonski.nazwa.pl/thedmd/allegro/5.0.10/allegro-5.0.10-msvc-11.0.7z

Can you write what kind of errors are you getting exactly?

That's not Allegro's issue (probably), you're probably using something which uses Process Status API, i.e. psapi.lib. I had a similar problem, you need to define a preprocessor directive:

Also you can try this:

Now I'm not 100% sure but I don't think that Allegro uses Process Status API.

Main cause for this error is because versions of Windows after Windows XP have moved functions (like those named upwards) from Process Status API (psapi.lib) to main kernel32.lib to gain more speed.

If Allegro uses psapi.lib then that's other story, and then it needs to be recompiled with MSVC2012 - Windows XP toolchain WITH preprocessor directive PSAPI_VERSION=1

Check your other libraries you are or might be using as well, if any of them are using psapi.lib then they should need to be recompiled too.

Yes you right.

But if allegro don't use PSAPI explicitly, it may use it implicitly via winmm or shell32 etc. libraries it linked with.

I think that even just small example allegro app won't run on xp with current build.
