Subject: [Xenomai] [PATCH 3/3] build: link dlopen libs with "nodelete"
Date: Tue, 24 Apr 2018 14:37:45 +0200	[thread overview]
Message-ID: <20180424123745.7015-4-henning.schild@siemens.com> (raw)
In-Reply-To: <20180424123745.7015-1-henning.schild@siemens.com>

This way a dlclose() will not unmap the libs memory anymore. A real
dlclose() will not work anyways because we lack destructors for all the
stuff we initialize in setup_descriptor->init().
