-// Since WRS does not yet properly support boost under vxWorks
-// and this file was badly outdated, but I was keen on using it,
-// I patched boost myself to make things work. This has been tested
-// and adapted by me for vxWorks 6.9 *only*, as I'm lacking access
-// to earlier 6.X versions! The only thing I know for sure is that
-// very old versions of vxWorks (namely everything below 6.x) are
-// absolutely unable to use boost. This is mainly due to the completely
-// outdated libraries and ancient compiler (GCC 2.96 or worse). Do
-// not even think of getting this to work, a miserable failure will
-// be guaranteed!
+// Old versions of vxWorks (namely everything below 6.x) are
+// absolutely unable to use boost. Old STLs and compilers
+// like (GCC 2.96) . Do not even think of getting this to work,
+// a miserable failure will be guaranteed!
+//
// Equally, this file has been tested for RTPs (Real Time Processes)
// only, not for DKMs (Downloadable Kernel Modules). These two types
// of executables differ largely in the available functionality of
-// the C-library, STL, and so on. A DKM uses a library similar to those
-// of vxWorks 5.X - with all its limitations and incompatibilities
-// with respect to ANSI C++ and STL. So probably there might be problems
-// with the usage of boost from DKMs. WRS or any voluteers are free to
-// prove the opposite!
-
+// the C-library, STL, and so on. A DKM uses a C89 library with no
+// wide character support and no guarantee of ANSI C. The same Dinkum
+// STL library is used in both contexts.
+//
+// Similarly the Dinkum abridged STL that supports the loosely specified
+// embedded C++ standard has not been tested and is unlikely to work
+// on anything but the simplest library.
+// ====================================================================
+//
+// Additional Configuration
+// -------------------------------------------------------------------
+//
+// Because of the ordering of include files and other issues the following
+// additional definitions worked better outside this file.
+//
+// When building the log library add the following to the b2 invocation
+// define=BOOST_LOG_WITHOUT_IPC
+// and
+// -DBOOST_LOG_WITHOUT_DEFAULT_FACTORIES
+// to your compile options.
+//
+// When building the test library add
+// -DBOOST_TEST_LIMITED_SIGNAL_DETAILS
+// to your compile options
+//
+// When building containers library add
+// -DHAVE_MORECORE=0
+// to your c compile options so dlmalloc heap library is compiled
+// without brk() calls
+//
// ====================================================================
//
// Some important information regarding the usage of POSIX semaphores:
// Now, VxWorks POSIX-semaphores for DKM's default to the usage of
// priority inverting semaphores, which is fine. On the other hand,
// for RTP's it defaults to using non priority inverting semaphores,
-// which could easily pose a serious problem for a real time process,
-// i.e. deadlocks! To overcome this two possibilities do exist:
-//
-// a) Patch every piece of boost that uses semaphores to instanciate
-// the proper type of semaphores. This is non-intrusive with respect
-// to the OS and could relatively easy been done by giving all
-// semaphores attributes deviating from the default (for in-depth
-// information see the POSIX functions pthread_mutexattr_init()
-// and pthread_mutexattr_setprotocol()). However this breaks all
-// too easily, as with every new version some boost library could
-// all in a sudden start using semaphores, resurrecting the very
-// same, hard to locate problem over and over again!
+// which could easily pose a serious problem for a real time process.
//
-// b) We could change the default properties for POSIX-semaphores
-// that VxWorks uses for RTP's and this is being suggested here,
-// as it will more or less seamlessly integrate with boost. I got
-// the following information from WRS how to do this, compare
-// Wind River TSR# 1209768:
-//
-// Instructions for changing the default properties of POSIX-
-// semaphores for RTP's in VxWorks 6.9:
-// - Edit the file /vxworks-6.9/target/usr/src/posix/pthreadLib.c
-// in the root of your Workbench-installation.
+// To change the default properties for POSIX-semaphores in VxWorks 7
+// enable core > CORE_USER Menu > DEFAULT_PTHREAD_PRIO_INHERIT
+//
+// In VxWorks 6.x so as to integrate with boost.
+// - Edit the file
+// installDir/vxworks-6.x/target/usr/src/posix/pthreadLib.c
// - Around line 917 there should be the definition of the default
// mutex attributes:
//
// pAttr->mutexAttrType = PTHREAD_MUTEX_DEFAULT;
//
// Here again, replace PTHREAD_PRIO_NONE by PTHREAD_PRIO_INHERIT.
-// - Finally, rebuild your VSB. This will create a new VxWorks kernel
+// - Finally, rebuild your VSB. This will rebuild the libraries
// with the changed properties. That's it! Now, using boost should
// no longer cause any problems with task deadlocks!
//
-// And here's another useful piece of information concerning VxWorks'
-// POSIX-functionality in general:
-// VxWorks is not a genuine POSIX-OS in itself, rather it is using a
-// kind of compatibility layer (sort of a wrapper) to emulate the
-// POSIX-functionality by using its own resources and functions.
-// At the time a task (thread) calls it's first POSIX-function during
-// runtime it is being transformed by the OS into a POSIX-thread.
-// This transformation does include a call to malloc() to allocate the
-// memory required for the housekeeping of POSIX-threads. In a high
-// priority RTP this malloc() call may be highly undesirable, as its
-// timing is more or less unpredictable (depending on what your actual
-// heap looks like). You can circumvent this problem by calling the
-// function thread_self() at a well defined point in the code of the
-// task, e.g. shortly after the task spawns up. Thereby you are able
-// to define the time when the task-transformation will take place and
-// you could shift it to an uncritical point where a malloc() call is
-// tolerable. So, if this could pose a problem for your code, remember
-// to call thread_self() from the affected task at an early stage.
