Enabling the threads USE flag and any of the boost, poco, or tbb USE flags breaks OgreXMLConverter. When threads IS NOT enabled, OgreXMLConverter works fine. Otherwise, it segfaults. Note that enabling the boost USE flag without the threads USE flag works fine. Reproducible: Always Steps to Reproduce: 1. Enable threads with any of the boost, poco, or tbb and recompile. 2. Run OgreXMLConverter on an Ogre XML file. 3. Smash head on keyboard when OgreXMLConverter segfaults. Actual Results: OgreXMLConverter segfaults without converting the XML file to a mesh. Expected Results: OgreXMLConverter should convert the XML file to a mesh.

According Ogre documentation (http://www.ogre3d.org/tikiwiki/tiki-index.php?page=CMake+Quick+Start+Guide&tikiversion=Linux), in Linux available only two threading models: 0 - Threading is disabled 2 - Threading with background resource preparation Mode 1 (Threading with full background resource loading) in Linux is NOT SUPPORTED. OGRE_CONFIG_THREADS is threestate variable. Meantime, in ebuild switch threading only with two - 0 or 1. So we need change this to 0 or 2: if use threads ; then local f for f in poco tbb boost ; do use ${f} || continue mycmakeargs+=( -DOGRE_CONFIG_THREADS=2 -DOGRE_CONFIG_THREAD_PROVIDER=${f} ) break done else mycmakeargs+=( -DOGRE_CONFIG_THREADS=0 ) fi
Additionly, error mentonied here http://www.ogre3d.org/mantis/view.php?id=425 is cause of wrong choiced threading model. Patch ogre-1.7.4-threading.patch is useless there.

However I cannot confirm that threading is _ever_ set to "1", meaning "full". look at the code: ##### if (OGRE_CONFIG_THREADS EQUAL 0) set(_threads "none") elseif (OGRE_CONFIG_THREADS EQUAL 1) set(_threads "full (${OGRE_CONFIG_THREAD_PROVIDER})") else () set(_threads "background (${OGRE_CONFIG_THREAD_PROVIDER})") endif () ##### since "OGRE_CONFIG_THREADS" is either "ON" or "OFF" it results in one of these: Threading support: background (none) Threading support: background (boost) Threading support: background (poco) Threading support: background (tbb) however that seems to break the following snippet because "ON" does not suffice "GREATER 0": ##### if (OGRE_CONFIG_THREADS GREATER 0) set(OGRE_CFLAGS "-pthread") set(OGRE_ADDITIONAL_LIBS "${OGRE_ADDITIONAL_LIBS} -lpthread") endif () ##### And that again breaks the pkgconfig files which are missing e.g. "-pthread". Seems no one noticed. This should do for that particular problem: - $(cmake-utils_use threads OGRE_CONFIG_THREADS) + $(usex threads "-DOGRE_CONFIG_THREADS=2" "-DOGRE_CONFIG_THREADS=0") Didn't check the other issue yet.
plz check if your OgreXMLConverter issue is related to bug https://bugs.gentoo.org/show_bug.cgi?id=418269
nah, seems not. OgreXMLConverter is just internal anyway. I can confirm that issue. Also on mesh -> xml
still broken with 1.8.1?
No reply.
for the book: does not happen with 1.8.1
