3 # this is a DF launcher, replacing the one that ships with DF.
4 # it's purpose is to launch DF through musl's libc.so, because the DF
5 # binary has GLIBC's dynlinker hardcoded as interpreter.
6 # additionally it launches DF through launch-without-heap-randomization.elf.
7 # it turned out that the way musl's malloc work, DF will crash pretty rapidly
8 # if heap randomization is enabled (linux default).
9 # launch-without-heap-randomization.elf will turn that off.
10 # you can compile it from launch-without-heap-randomization.c:
11 # gcc launch-without-heap-randomization.c -o launch-without-heap-randomization.elf

16 #export SDL_VIDEO_CENTERED=1 # Centre the screen. Messes up resizing.

28 required:
29 libc.so (musl)
30 libncursesw.so.5
31 libSDL_image-1.2.so.0
32 libz.so.1
33 libSDL_ttf-2.0.so.0
34 libSDL-1.2.so.0 (must be compiled with sabotage's pthread stacksize patch)
35 libstdc++.so.6 (supplied)
36 libgcc_s.so.1 (supplied)
38 optional for sound support:
39 libopenal.so
40 libsndfile.so
42 those 2 depend on other libs themselfes:
43 libvorbis, libogg, alsa-lib and possibly more.
