When building the static libs for tbb and linking them into another project, the build of the libs had various defines wrongly set; which resulted in various linker warnings. This changelist includes the fixes for the properties related to the static build of tbb.
Build-specific postfixes are a relic of build systems that place
binaries from multiple different build types into the same output
directory. This is needlessly confusing and not necessary for
CMake-based build systems, since they either use a fixed build type
(Linux: Ninja, Makefile generators) or separate configurations with
different output directories (MSVC).
* Fix TBB_BUILD_TESTS option
- If TBB_BUILD_TESTS is set to ON, then actually build the unit test
binaries. Previously, the binaries' executable targets would be
defined in CMakeLists.txt, but set to EXCLUDE_FROM_ALL, which would
cause ctest to fail.
- Prefix all TBB test binaries and test names with tbb_test. Previously,
very generic-sounding test names and executable target names would be
created, which is IMO bad behavior in a repository meant to be used as
a library.
- Clean up some style formatting for consistency in root CMakeLists.txt.
* Fix .appveyor.yml and .travis.yml to not refer to now-deleted tests build target
This flag also sets -D_LIBCPP_VERSION, which ensures that various
ifdef (_LIBCPP_VERSIONS) in tbb_config.h are triggered even when no
libc++ header is included yet.
Compiler flags are optionally set for usign clang on
linux with different glibc versions.
These flags have been migrated from the makefile to
the CMakeLists.txt file.
This resolves#18.
The new release TBB is now under a new more
open license.

The list of most significant changes made over time in
Intel(R) Threading Building Blocks (Intel(R) TBB).
Intel TBB 2017
TBB_INTERFACE_VERSION == 9100
Changes (w.r.t. Intel TBB 4.4 Update 5):
- static_partitioner class is now a fully supported feature.
- async_node class is now a fully supported feature.
- Improved dynamic memory allocation replacement on Windows* OS to skip
DLLs for which replacement cannot be done, instead of aborting.
- Intel TBB no longer performs dynamic memory allocation replacement
for Microsoft* Visual Studio* 2008.
- For 64-bit platforms, quadrupled the worst-case limit on the amount
of memory the Intel TBB allocator can handle.
- Added TBB_USE_GLIBCXX_VERSION macro to specify the version of GNU
libstdc++ when it cannot be properly recognized, e.g. when used
with Clang on Linux* OS. Inspired by a contribution from David A.
- Added graph/stereo example to demostrate tbb::flow::async_msg.
- Removed a few cases of excessive user data copying in the flow graph.
- Reworked split_node to eliminate unnecessary overheads.
- Added support for C++11 move semantics to the argument of
tbb::parallel_do_feeder::add() method.
- Added C++11 move constructor and assignment operator to
tbb::combinable template class.
- Added tbb::this_task_arena::max_concurrency() function and
max_concurrency() method of class task_arena returning the maximal
number of threads that can work inside an arena.
- Deprecated tbb::task_arena::current_thread_index() static method;
use tbb::this_task_arena::current_thread_index() function instead.
- All examples for commercial version of library moved online:
https://software.intel.com/en-us/product-code-samples. Examples are
available as a standalone package or as a part of Intel(R) Parallel
Studio XE or Intel(R) System Studio Online Samples packages.
Changes affecting backward compatibility:
- Renamed following methods and types in async_node class:
Old New
async_gateway_type => gateway_type
async_gateway() => gateway()
async_try_put() => try_put()
async_reserve() => reserve_wait()
async_commit() => release_wait()
- Internal layout of some flow graph nodes has changed; recompilation
is recommended for all binaries that use the flow graph.
Preview Features:
- Added template class streaming_node to the flow graph API. It allows
a flow graph to offload computations to other devices through
streaming or offloading APIs.
- Template class opencl_node reimplemented as a specialization of
streaming_node that works with OpenCL*.
- Added tbb::this_task_arena::isolate() function to isolate execution
of a group of tasks or an algorithm from other tasks submitted
to the scheduler.
Bugs fixed:
- Added a workaround for GCC bug #62258 in std::rethrow_exception()
to prevent possible problems in case of exception propagation.
- Fixed parallel_scan to provide correct result if the initial value
of an accumulator is not the operation identity value.
- Fixed a memory corruption in the memory allocator when it meets
internal limits.
- Fixed the memory allocator on 64-bit platforms to align memory
to 16 bytes by default for all allocations bigger than 8 bytes.
- As a workaround for crashes in the Intel TBB library compiled with
GCC 6, added -flifetime-dse=1 to compilation options on Linux* OS.
- Fixed a race in the flow graph implementation.
Open-source contributions integrated:
- Enabling use of C++11 'override' keyword by Raf Schietekat.
