async_node simple examples needed

I'm interested in async_node functionality. Tried to compile the example in doc using VisualStudio 2015, but get errors that I can't seem to figure out (templates are hard to debug). Could you provide a couple of "as simple as possible, but no simpler" style of examples that illustrate the basic functionality of async_node, and work in VisualStudio?

Building tbb U6 with gcc 4.9.2


I have been trying ti build the tbb from source code using gcc 4.9.2.

a) if you could point me to a location where I could find it already built, would be ideal.

b) if not, can you please point to a location with instructions for how to build?

Right now all I am doing is typing gmake and hacking the "make" files (.inc) to add manually a couple of flags for the gcc locale (namely -D__USE_XOPEN2K8 and -std=c++11) but these do not properly propagate, as this shows:

index of keys in concurrent hash map


I am using tbb's concurrent hash maps and I am wondering if there is someway to find out the index of a key in the map.

So for example i declare my map like this

typedef tbb::concurrent_hash_map< openvdb::Coord, int, MyHashCompare> single_map;

where openvdb::Coord is a unique co-ordinate in the R3 /(3D)/[x,y,z] space.

Cannot find composite_node with clang

I experiment with the TBB composite node and the TBB CMake scripts.

My test repository https://github.com/thedarksideofthemoon/tbb-test works fine when I compile it using GCC 5.4 at Ubuntu 16.04. However, I cannot get my test program to compile with Clang 6.0. Instead, I get the compiler error error: unknown template name 'composite_node'.

Do I need any additional flags to find the composite_node?

Compiling TBB 2017 U7 under C++17


I'm trying to get TBB 2017 U7 compiling with GCC 7.1, using C++17 (or rather, --std=c++1z) mode. I hacked the linux.gcc.inc file to add the appropriate flag, but compilation failed due to use of dynamic exception specifications in tbbmalloc. Specifically:



There may, of course, be others but I can only get this far.

Dynamic exception specifications are removed in C++17. Not only that, they have been deprecated since C++11. I believe they could be removed without significant impact. How about it?
