I just pulled the latest source, but I've forgotten how to compile on Mac.  XP

Please refresh me on compilation instructions, thanks!

You need:
Allegro 5.1.11+ (may have to build this yourself, https://github.com/liballeg/allegro5)
libmng
zlib

From the command line, switch to the minisphere source directory and run scons which will build minisphere and Cell in the bin/ subdirectory.

Gave a missing libmng error (pretty much the only library error left after all the previous work I did before), DLed libmng 2.0.3 from Sourceforge, one `./configure; make; sudo make install` later was able to scons minisphere!

Running my two tests worked ok, running Radnen's Cellar Rush gave a LoadSound() error - failed to load some ogg file. I've previously had trouble building Allegro on this Mac with extended sound capabilities (including anything libogg related), so this one's probably on me.

Other than Allegro-specific or me-specific things like the libogg issue, it builds on Mac OS X Mavericks! I'll take a look at Allegro stuff later.

This current building served two purposes: make sure current minisphere builds and runs on Mavericks, and set up a prep environment related to my game dev and my RFC about adding Python.

Here's the thing with Allegro: By default it dynamically loads audio codecs such as libogg at runtime, and gracefully degrades if they are missing (this is annoying).  You can static link them if you disable the CMAKE flag WANT_ACODEC_DYNAMIC_LOAD, not sure how feasible that is on OS X though.  Either way, additional dependencies needed for Allegro audio:

dumb
libFLAC
libogg
libvorbis
libvorbisfile

They really need to get rid of that "dynamic link by default" feature, it causes so many headaches.

@NEO: Did you get Allegro to build properly with sound support?

Not yet; for reference, Allegro's cmake is giving me the following output (tl;dr - I'm missing libFLAC, libdumb, libvorbis):

You think this is bad, you should have seen me try to build Allegro on Windows when I first upgraded to 5.1.  Even with CMake it's a nightmare, sometimes it doesn't find libraries that are actually present, or they'll fail a compile test for no reason at all (which CMake then "remembers" and won't try again until you blow away the entire build cache and start over).  This is why I'm still using Allegro 5.1.11 even though 5.1.12 has some new stuff that would actually be useful to have (such as cross-platform clipboard support).

Allegro is a great library, but their build process needs a lot of work.

I got minisphere to compile with Chipmunk2D linked in.  So minisphere 2.2 will definitely have some kind of physics support, once I figure out a good API structure.

Originally I was going to try to copy the particle engine from Sphere 1.6, but I'm thinking now that a more general-purpose physics engine will be better in the long run.

CMake is just always a bit of a nightmare. This is a pretty normal experience with it, especially on Windows.


In large part this seems to be caused by CMake's braindead caching setup: When a variable is set, its value is stored in the CMakeCache and future accesses will always just read from the cache.  There doesn't appear to be any kind of conditional logic where the cached value can be ignored when something related to it changes.

Just implemented: Error copying.  Finally you can press Ctrl+C on the error screen to copy error text (and filename/line number) directly to the clipboard.  This has been a long time coming.

Ok, that's it. I'm done with Sphere 1.5/1.6. That was the secret. I wanted you to do that, but never said, and now that you did it, bye bye Sphere 1.5/1.6. :)
If you use code to help you code you can use less code to code. Also, I have approximate knowledge of many things.

Hehe.  I wanted to do this a while ago, but I was too lazy to research the clipboard APIs for the different platforms.  As of Allegro 5.1.12, basic clipboard functions are built-in, so I took advantage of it.

2.1.3 doesn't include the feature, but it's in the git repository anyway (Windows build requires VC++2015).  If I release a 2.1.4 I'll backport it, otherwise it'll be in v2.2 along with some sort of physics support.  I haven't quite worked out a good API for that yet.

Okay, Radnen, you lucked out, I had to fix a map engine bug related to GrabImage() (actually a regression due to a careless recent change to the map update loop) so I released a hotfix.  Said hotfix happens to include the error message copying, so now you can download minisphere 2.1.4 and ditch Sphere 1.x if you want. ;)

As for physics, the API is going to need some more thought before I forge ahead with it, so I'm postponing it to minisphere 3.0.  Instead I think I'll dedicate minisphere 2.2 to improving Cell.  What was released of it with minisphere 2.0 is little more than a prototype and I'd like to make it a more invaluable part of the Sphere toolchain.

Having an issue building this again on OS X - I've installed Allegro 5.0.11 through homebrew and I'm getting this when running scons:
