Arch Linux User Repository

Hiya, I updated the package. ceidways's patch was implemented. Should be working good for now.

GCC issue fixed upstream as of ver 3.1.1

I updated the PKGBUILD and removed the patch 0001-man-docgen-Use-raw-string-literals-for-regular-expre.patch which was implemented upstream.

Tested and working on Arch Linux x86_64 (2025-12-19) GCC 15.2.1

Patch here: https://gist.github.com/ceidways/44c907c20621fd601a25eaa61889d1c8

(First time doing anything for AUR. Did my best research but please tell me if I missed anything)

Marked out-of-date due to no update in around two months since the GCC issue was reported

Alternatively, here is a patch you can apply to the source itself:

 typedef bool boolean;

After doing some fiddling, it seems the issue is due to C23 making true and false into keywords, with choclate doom defining true and false itself as an enum. An easy fix to get it working is to force it to compile as C17 instead.

diff of PKGBUILD:

43c43
<   ./configure --prefix=/usr
---
>   CFLAGS='--std=c17' ./configure --prefix=/usr

get same errors as Jvazrk below

Hmm, is this project still alive? Anybody who can help out configuring the background music? I set up some arch linux machines and on none the music is working out of the box, although it installs timidity as a dependency.

Thanks for providing this great application. Since a while I don't have any background sound and get the message "Error loading midi: Couldn't open timidity.cfg". When setting timidity_cfg_path in the config file to a valid timidity.cfg, it says "Error loading midi: Couldn't open /tmp/timidity.cfg" although I set the path to something else than /tmp/timidity.cfg (but problem persists when setting it to /tmp/timidity.cfg, too). So far I think it's my fault and like to ask for help here. When copying a valid timidity.cfg to /tmp/timidity.cfg, chocolate doom will delete it and display "Error loading midi: Couldn't open /tmp/timidity.cfg", at least for this I'm sure it's a bug.
