Subject: [PATCH nolibc 03/19] tools/nolibc: mark start_c as weak
Date: Thu, 12 Oct 2023 12:32:17 -0700 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <b34ce3cf-3fcc-4eb0-a658-229c197455ef@paulmck-laptop>
From: Thomas Weißschuh <[email protected]>
Otherwise the different instances of _start_c from each compilation unit
will lead to linker errors:
/usr/bin/ld: /tmp/ccSNvRqs.o: in function `_start_c':
nolibc-test-foo.c:(.text.nolibc_memset+0x9): multiple definition of `_start_c'; /tmp/ccG25101.o:nolibc-test.c:(.text+0x1ea3): first defined here
Fixes: 17336755150b ("tools/nolibc: add new crt.h with _start_c")
