Stonesense segfault on OS X

[ELLIOTTCABLE]

I'm getting the same segmentation-fault described later-on in #576; but I wanted to open a new Issue to record it. As soon as I invoke stonesense at the DFhack prompt, I get a segmentation-fault:

[DFHack]# stonesense
Stonesense launched
Using allegro version 5.0.9 r1
!! /opt/homebrew-cask/Caskroom/dwarf-fortress/0.40.24/df_osx/dfhack: line 15: 20843 Segmentation fault: 11  DYLD_INSERT_LIBRARIES=./hack/libdfhack.dylib ./dwarfort.exe "$@"

Here are the CLI-output, stdout.log, and stderr.log, from my original invocation: f9c3c46d9ae019f6357d

Here's the same, as well as the OS X ‘crash report’ (basically, stack trace) from the same command, with DFHACK_LOG_MEM_RANGES enabled: 03471f43b7fd30c8229a

I'm running a freshly-installed (via Homebrew) v0.40.24 of DF, with DFhack from dfhack-0.40.24-r3-OSX.

Note: I tried to use the prebuilt and updated liballegro.5.0.11 files that @lethosor suggested, downloaded from here, but those weren't built for my arch, and I'm not sure how to go about building them:

Output:

Can't load plugin .../df_osx/hack/plugins/stonesense.plug.dylib

stderr.log:

[lethosor]

The allegro libraries should be fine - what's missing is a 32-bit version of libfreetype. Try updating the SDL_ttf library from here.

[ELLIOTTCABLE]

@lethosor hm, I'm averse to manipulating /Library/Frameworks; is there a pre-built SDL_ttf that I can drop into df_osx/hack/libs/ instead? Or, alternatively, a way to use a Homebrew-built SDL? (I've got libSDL_ttf-2.0.0.dylib in /usr/local/Cellar/sdl_ttf/2.0.11/lib, but I'm not too familiar with how dynamic linking works, and how to get DFhack to use that.)

[lethosor]

is there a pre-built SDL_ttf that I can drop into df_osx/hack/libs/ instead?

That's what I meant (download SDL_ttf-2.0.11.dmg and drop SDL_ttf.framework into DF/libs/ or DF/hack/ - DF/hack/libs/ probably won't work, unless you modify the dfhack script).

I think ~/Library/Frameworks would also work.

[ELLIOTTCABLE]

Do I need to remove liballegro_ttf? It's still not working; same error:

dlopen(/opt/homebrew-cask/Caskroom/dwarf-fortress/0.40.24/df_osx/hack/plugins/stonesense.plug.dylib, 6): Library not loaded: /Volumes/MacintoshHD/brew-mavericks/lib/libfreetype.6.dylib

[lethosor]

Removing liballegro_ttf will break Stonesense. Did you update SDL_ttf? If you did and it still doesn't work, you could try adding libs/SDL_ttf.framework/Frameworks to DYLD_LIBRARY_PATH in the df and dfhack scripts.

[lethosor]

Actually, SDL_ttf would only fix DF's libfreetype dependency, not allegro's - is there a libfreetype.6.dylib in hack/libs? Try copying that to the libs or hack folders.

[ELLIOTTCABLE]

Success! (For future reference: copying df_osx/hack/libs/libfreetype.6.dylib to df_osx/hack, and then replacing df_osx/hack/libs with the unpacked contents of liballegro.5.0.11 provided above.)

I can finally try Stonesense! So excited! <3
