alsa-utils 1.2.10 fails to build with old gcc
by GitHub issues - opened 04 Sep '23

04 Sep '23

alsa-project/alsa-utils issue #233 was opened from tiwai: The recent change for fixes builds on the latest gcc broke the builds on the older gcc version instead. The truncated parameters can't be handled well by the older gcc. I guess we should rather add the option to ignore the unused parameters instead of truncating unused parameters. Not all compilers support those new syntax. Issue URL : https://github.com/alsa-project/alsa-utils/issues/233 Repository URL: https://github.com/alsa-project/alsa-utils

Alsa Lib segfaults when built statically

04 Sep '23

alsa-project/alsa-lib issue #349 was edited from cybersoulK: I am building a game that uses alsa. All of my linux players segfault. This has been going for over 1 year. Alsa-lib is built statically on a ubuntu machine with the following commands: ``` git clone https://github.com/alsa-project/alsa-lib cd alsa-lib apt-get update apt-get install libtool apt-get install make apt install autoconf autoreconf -i ./configure --disable-shared make ``` Then i use libasound.a to build my Rust executable (On my mac machine). I do the same process to build openssl for linux and it works great. So There definitely is an issue when building alsa lib statically. One of my players was able to provide me with a core dump that might be helpful to track down the fault: <img width="770" alt="image" src="https://github.com/alsa-project/alsa-lib/assets/102260392/7390b851-47a1-4e5…"> [coredump.txt](https://github.com/alsa-project/alsa-lib/files/12508784/cored… Issue URL : https://github.com/alsa-project/alsa-lib/issues/349 Repository URL: https://github.com/alsa-project/alsa-lib

[PATCH 0/2][RFC] Refactor snd primitives refcounters

From: Curtis Malainey <cujomalainey(a)chromium.org> As previously identified in [1] there are some issues with how kobjs are handled in sound/core. The solution provided in [2] is a workaround for the issues to fix the failures. This series is a first attempt at the larger refactor needed to properly handle the objects.
