Subject: [Buildroot] [PATCH] package/uclibc: add patch for libucontext usage
Date: Wed, 17 Jul 2024 17:12:54 +0200 [thread overview]
Message-ID: <Zpffdv/lWI4det+1@waldemar-brodkorb.de> (raw)
*ucontext functions are only implemented for a subset of
uClibc supported architectures. To allow the external library
libucontext to be used this small patch is required.
Tested for riscv64.
