From d493979e8c4419b3bde09228c594ea84cd842aaa Mon Sep 17 00:00:00 2001 From: Ismael Luceno Date: Sat, 19 Sep 2026 05:51:43 +0200 Subject: [PATCH 05/12] Use realpath() instead of canonicalize_file_name() canonicalize_file_name() is a GNU extension. musl does not provide it, so client-nss.cxx and session.cxx fail to compile there: session.cxx:1565:15: error: 'canonicalize_file_name' was not declared POSIX.1-2008 realpath(path, NULL) is defined to do the same thing -- resolve the path and return a malloc'd buffer -- and both call sites already free() the result, so the change is a straight substitution.
