From b845a1541f4c40e028a7351ca183ea3c6db56246 Mon Sep 17 00:00:00 2001 From: Romain Naour Date: Mon, 1 Aug 2016 18:30:21 +0200 Subject: [PATCH] package/xenomai: disable for musl toolchains After fixing the issue by using , the build still fail with udefined __WORDSIZE. Adding to define __WORDSIZE reveal that xenomai use which is not provided by musl. The discussion on the musl mailing list [1] about glibc error reporting functions concluded to not add this support in the C library. For now, disable Xenomai user space support for musl toolchains since it require several patches to build correctly and needs to remove each glibc error reporting functions. Users interested in musl support for Xenomai can work with upstream to fix these issues and revert this patch.
