From 63ffe00d8c939eda1a8fa87484ca4537e13a20b7 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Tue, 27 Dec 2022 15:48:21 -0600 Subject: kbuild: Fix running modpost with musl libc commit 3d57e1b7b1d4 ("kbuild: refactor the prerequisites of the modpost rule") moved 'vmlinux.o' inside modpost-args, possibly before some of the other options. However, getopt() in musl libc follows POSIX and stops looking for options upon reaching the first non-option argument. As a result, the '-T' option is misinterpreted as a positional argument, and the build fails: make -f ./scripts/Makefile.modpost scripts/mod/modpost -E -o Module.symvers vmlinux.o -T modules.order -T: No such file or directory make[1]: *** [scripts/Makefile.modpost:137: Module.symvers] Error 1 make: *** [Makefile:1960: modpost] Error 2 The fix is to move all options before 'vmlinux.o' in modpost-args.
