alsa-project/alsa-utils pull request #272 was opened from marc-hb: Fixes cryptic "error macro 'AM_PATH_ALSA' not found in library configure.ac:22" when attempting a local install as described at https://thesofproject.github.io/latest/getting_started/build-guide/build-from-scratch.html#build-alsa-lib-and-alsa-utils-from-source Fixes giant commit f9e6010d5ec7 ("topology: plugins - add Intel nhlt encoder plugin") which added a second invocation of `aclocal` in 2021 but forgot the extra `$alsa_m4_flags`. To avoid duplication, do not fix by adding the missing `$alsa_m4_flags` to the second aclocal invocation. Instead, drop that variable and append `-I ../alsa-lib/utils` directly to $ACLOCAL_FLAGS Request URL : https://github.com/alsa-project/alsa-utils/pull/272 Patch URL : https://github.com/alsa-project/alsa-utils/pull/272.patch Repository URL: https://github.com/alsa-project/alsa-utils
