From 9e38be732da8fe3c970c2c9f6169d5aa38bf0d72 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 6 Apr 2023 17:19:11 +0100 Subject: [PATCH] kselftest: Support nolibc Rather than providing headers for inclusion which replace any offered by the system nolibc is provided in the form of a header which should be added to the build via the compiler command line. In order to build with nolibc we need to not include the standard C headers, especially not stdio.h where the definitions of stdout, stdin and stderr will actively conflict with nolibc. Add an include guard which suppresses the inclusion of the standard headers when building with nolibc, allowing us to build tests using the nolibc headers. This allows us to avoid open coding of KTAP output for selftests that need to use nolibc in order to test interfaces that are controlled by libc.
