Subject: [igt-dev] [PATCH v2 1/6] build: check that outb is present in io.h
Date: Thu, 26 Oct 2023 19:14:35 +0200	[thread overview]
Message-ID: <20231026171440.4046190-2-bernd@kuhls.net> (raw)
In-Reply-To: <20231026171440.4046190-1-bernd@kuhls.net>

With glibc if io.h exists, inb/outb are always defined.
However on musl, io.h always exists but it may not define inb/outb.

Thus, igt-gpu-tools builds with musl on non-x86 platforms will fail to
link. Fix this by checking for both io.h and that outb() is defined.
