+Subject: [PATCH] meson: Pass --export-dynamic option to linker
+
+Bypass the compiler driver trying to comprehend and translate it for
+linker, since its not clear what the right behavior should be, gcc seems
+to translate it into --export-dynamic but clang 18+ rejects it
+
+| x86_64-yoe-linux-clang: error: unknown argument: '-export-dynamic'
+
+also see [1]
+
+This makes it work as intended across gcc and clang
+
+Upstream-Status: Submitted [https://gitlab.gnome.org/GNOME/libgudev/-/merge_requests/30]
