ARM issues

[Baron Pampa]

Hi:)

This time I've messed around with Eternity on PinebookPro, an ARM laptop with Manjaro. The good news is that Eternity is working, but I wanted to raise two issues:
- when trying to compile the AUR version(straight from git), an error stops the compilation:
[ 19%] Built target ADLMIDI_static

compilation terminated.

After some research I've compiled it with libpng 1.6.35. Newest version, 1.6.37 is not working. Is it possible to dynamically link libpng or update it's version in the repo?

More serious issue: when exiting the game, program crashes or hangs. Crash happens with "corrupted double-linked list" message, I think that sometimes it segfaults. Most often it doesn't quit at all and I need to kill the process. It wouldn't be much of an issue if not for the fact that it's impossible to save the config. If you are interested in fixing that I'd be glad to help with providing logs or a debug stack trace.

Try if it happens if you disable ENDOOM. Go to the video settings in the menu to disable ENDOOM.

Your error looks strange: it complains about a macro? Anyway that seems like a change to do in CMakeLists.txt. I'm writing that as a GitHub task.

Never had CSG complain about this when using Raspbian before. Must be new or a Manjaro thing, or could PKGBUILD be to blame?

[Baron Pampa]

@Altazimuth

I doubt it's PKGBUILD since after the first error I've switched to compiling code straight from your git.

@printz

I've just tried. It seems that after disabling ENDOOM result consequently is:

malloc(): unsorted double linked list corrupted

Aborted (core dumped)

Hmm. For such stuff, valgrind would help. I haven't used CMake+make lately to make debug builds. But try running valgrind with a debug build of Eternity and post here the output in case of crash.

Sorry for the delay - I have other stuff like most of us, so usually it takes me a few days to try something out and respond.

I'll attach log from valgrind shortly.
