libtcod-mac's Issues

_TCOD symbols not found

Running make -f makefiles/makefile-osx spits out a lot of errors. I'm sure this is an error on my part, but I've still been unable to resolve it so far.

keyboard input broken with SDL2

This repo is behind the original trunk. There is a bug with SDL2 described here:
https://bitbucket.org/jice/libtcod/issue/39/proposed-sdl2-unknown-pressed-character

If you can merge in the changed from jice's repo, it will fix them. With this repo, the TCOD_key_t foo.shift boolean wasn't working and I couldn't get capital letters. The newest libtcod adds a "text" element to get the right input from SDL2.

All that said, thanks for posting this fork. The makefile worked great and saved me a headache.

State of this Mac fork

Hi,

I'm replacing jice as the libtcod maintainer. People have been mentioning to me that the Mac support isn't working for them. I don't have a Mac so I thought I'd ask here, as it seems to have recent changes.

• References to linker errors and x64isms.

The end result I am looking for is for any Mac developers to at least be able to compile their own version, and better yet some way to get builds done (ideally with scripting language bindings) so that Mac users get the same level of accessibility as Windows users.

What are your thought on the state of things Mac-wise?

path_compute causes Segmentation Fault 11

Hi there!

Thank you very much for your work on making this port available! I've run into very few issues with it save for this one :P However, there is certainly a chance that I simply compiled the source wrong or something...

It seems that whenever I try to use the libtcod.path_compute() method from Python 2.7.10 on OS X (El Capitan) Python crashes with "Segmentation fault: 11". There is no other output.

Has anyone else experienced this issue? I've spent a little time searching the net but haven't found anyone else discussing this precise issue...

Please let me know if I can provide any additional information. I'm a C newbie so I'm still not sure what kinds of debug information is available/useful.

Thanks!

upx is a dependency

Heads up, upx is a dependency for the samples.

Before making the samples, e.g.
make -f makefiles/makefile-samples-linux-sdl2 release
or
make -f makefiles/makefile-samples-linux-sdl release
you'll need to
brew install upx

p.s. Thanks for all the hard work getting this ported to OSX!

slightly wrong SDL.h path

I just installed and compiled this.

One interesting thing, is that in most places, it looks for SDL/SDL.h but in the libtcod.h file there is a ifdef for OSX, that looks into only <SDL.h>, this made samples fail to compile on my machine.

Upon changing line 109 of libtcod.h to <SDL/SDL.h> then it worked correctly.

Calling console_blit causes Segmentation Fault 11

I'm not quite sure what else to report. I tried this having built with both SDL and SDL2. I've tried blitting two non-root consoles and I still see the issue. Any advice?

Thanks :)

Trying to compile & run on OSX 10.11

I have here a summary of a partially-successful attempt to build & run libtcod on OSX 10.11 using libraries from MacPorts.

1. The dependencies (SDL2, upx, ...) are available from MacPorts as well as homebrew.
2. The samples do not compile out of the box following the instructions. To get them to compile I had to do the following:
   2a) Add $(SDL_LIBS) to CFLAGS in makefile-samples-linux-sdl2
   2b) Comment out all the conditional crap about SDL.h from samples_c.c and samples_cpp.cpp and just write #include <SDL.h>
3. The samples run, but various features end up crashing the demo. I can provide more details if someone will actually investigate.
4. The python sample starts to run, but it crashes with an Abort trap: 6

Unfortunately I wish to use the python bindings, so the partial success is not enough to let me do the tutorial I found.
