Subject: [PATCH 1/6] PR build/11881: LIBTHREAD_DB_SO can be undefined.
Date: Wed, 17 Apr 2013 00:55:00 -0000 [thread overview]
Message-ID: <20130416183050.540.27315.stgit@brno.lan> (raw)
In-Reply-To: <20130416183043.540.32214.stgit@brno.lan>
This patch:
http://sourceware.org/ml/gdb-patches/2009-04/msg00115.html
Changed behaviour by only defining LIBTHREAD_DB_SO if thread_db.h exists. The
definition of LIBTHREAD_DB_SO and LIBTHREAD_DB_SEARCH_PATH should be moved
outside of #ifdef HAVE_THREAD_DB_H.
This is based on a patch attached to the PR, however, it needed a
tweak, as it was it broke the HAVE_THREAD_DB_H path.
