From 58fd33186c111c53b3fd1280cbbad0f0dd5342ec Mon Sep 17 00:00:00 2001 From: Ismael Luceno Date: Sat, 19 Sep 2026 05:53:08 +0200 Subject: [PATCH 08/12] Tolerate a C library without FNM_EXTMATCH tapsets.cxx passes FNM_EXTMATCH to fnmatch() when matching kernel function names. The flag is a GNU extension; musl does not have it, so the build stops with tapsets.cxx:12341:71: error: 'FNM_EXTMATCH' was not declared in this scope Define it to 0 when absent. Ordinary glob patterns keep working; only the ksh-style !(...) / @(...) extended patterns are unavailable, and those cannot be supported without an extended fnmatch() in any case.
