View file @ f442920e
==============================
19.04.16 Release CLHEP-2.3.2.1
==============================
2016-04-19 Lynn Garren <garren@fnal.gov>
* gcc must be gcc 4.8 or better
* clang must be 3.5 or better
* cmake: Remove obsolete cmake macros
* cmake: Set CMAKE_SHARED_LINKER_FLAGS
* cmake: Use find_package(Threads)
2016-03-25 W. David Dagenhart <wdd@fnal.gov>
* Utility/Utility/use_atomic.h: Use std::atomic when the compiler declares it
uses the C++11 standard
2016-03-25 W. David Dagenhart <wdd@fnal.gov>
* Random/src/MixMaxRng.cc: The uncorrected code might not always yield independent seeds.
If two threads execute numberOfEngines++ and after both finish that both
execute setSeed, then they will have the same seed. Fixed.
* Random/src/Random.cc: There is a thread local variable of the type "defaults"
that contains two shared_ptr's in Random.cc. This causes an intermittent
problem on OSX. The complex objects containing the shared_ptr's have been
moved into a list of objects and the now the thread_local only contains a
simple pointer now that points into the list.
Use the new Utility/use_atomic.h header.
