Christian Heimes added the comment: I noticed that 9 test suites are failing on Alpine 3.15, see bpo-46390. Should we require a stable buildbot before we proclaim official support for Alpine? -- dependencies: +Multiple test failures on Alpine 3.15 / musl-1.2.2-r7

Henry Schreiner added the comment: We had a call and have a potential path forward. Quick summary: * Add a patch on top of the current patch to make CPython look for `-gnu` on top of `-musl` for Alpine 3.15 and 3.14. Reverting the patch would break every Alpine wheel previously locally

Tzu-ping Chung added the comment: Can anyone problem examples that it’s not an option to continue using the “technically incorrect” `-gnu` suffix on 3.9 and 3.10? From what I understand, te suffix technically works (as in the module will load correctly), it just fails to distinguish the ABI

Natanael Copa added the comment: This mentions some examples for musl triplets/tuples: https://wiki.musl-libc.org/getting-started.html It points to https://github.com/richfelker/musl-cross-make/blob/master/README.md#supported-targets which I think is the best documentation. (Rich Felker is

Christian Heimes added the comment: I stand corrected. The last element in the platform triplet does seem to indicate libc. Is there any formal definition of the platform triplet or is it defined by GCC's reference implementation? A quick search didn't reveal any decisive results. The

Natanael Copa added the comment: > Do you have glibc and musl installed side by side? No. But there is nothing preventing me to have the libc runtimes installed in parallel with glibc. /lib/libc.so.6 /lib/libc.musl-x86_64.so.1 And it is not common that people copy libc.so.6 (with friends)

[issue43112] SOABI on Linux does not distinguish between GNU libc and musl libc

Christian Heimes added the comment: SOABI basically contains the CPU architecture and Kernel ABI. The libc ABI is yet another dimension that is not encoded in the shared library ABI. The libc ABI is more complex than just glibc or musl. You need to include the ABI version of all core

Natanael Copa added the comment: The referenced https://wiki.debian.org/Multiarch/Tuples doc says: > we require unique identifiers for each architecture that identifies an > incompatible set of libraries that we want to be co-installed. Since GNU libc and musl libc are not ABI compatible

[issue43112] SOABI on Linux does not distinguish between GNU libc and musl libc

Christian Heimes added the comment: The suffix "-gnu" does not stand for "glibc". The triplet defines the calling convention. For example x86_64-linux-gnu means x86_64 / AMD64 CPU architecture, Linux, with standard GNU / GCC calling convention. Other calling conventions are

New submission from Natanael Copa : The SOABI does not make any difference between GNU libc and musl libc. Using official docker images: # debian build with GNU libc $ docker run --rm python:slim python -c 'import sysconfig;print(sysconfig.get_config_var("SOABI"))'
