Just::Thread Pro v2.5.0 released with coroutines support

Friday, 15 September 2017

I am pleased to announce that Just::Thread Pro v2.5.0 has been released. This adds support for gcc 7, clang 4.0 and clang 5.0, but the big change with this version is the support for coroutines with Microsoft Visual Studio 2017, and clang 5.0 on ubuntu when used with libc++ 5.0.

Just::Thread Pro is our C++ concurrency extensions library which provides an Actor framework for easier concurrency, along with concurrent data structures: a thread-safe queue, and concurrent hash map, and a wrapper for ensuring synchronized access to single objects.

It also includes the new facilities from the Concurrency TS:

• Latches
• Barriers
• atomic_shared_ptr and atomic_weak_ptr
• future::then()
• when_any()
• when_all()

Coroutines support is here!

V2.5.0 adds support for coroutines with Microsoft Visual Studio 2017 and clang 5.0. This means that you can now use co_await to wait for a std::experimental::future, and can create coroutines that return a std::experimental::future.

Supported compilers

Just::Thread Pro is now fully supported on the following compiler/OS combinations (32-bit and 64-bit):

• Microsoft Visual Studio 2015 for Windows
• Microsoft Visual Studio 2017 for Windows
• gcc 5 for Ubuntu 14.04 or later
• gcc 6 for Ubuntu 14.04 or later
• gcc 7 for Ubuntu 14.04 or later
• clang 3.8 for Ubuntu 16.04 or later
• clang 3.9 for Ubuntu 16.04 or later
• clang 4.0 for Ubuntu 16.04 or later
• clang 5.0 for Ubuntu 16.04 or later with libc++ or libstdc++
• gcc 5 for Fedora 22 and 23
• gcc 6 for Fedora 24 and 25
• gcc 7 for Fedora 26
• clang 3.8 for Fedora 24
• clang 3.9 for Fedora 25
• clang 4.0 for Fedora 26

Just::Thread Pro v2.2 is also supported with the Just::Thread compatibility library on the following compiler/OS combinations:

• Microsoft Visual Studio 2005, 2008, 2010, 2012 and 2013 for Windows
• TDM gcc 4.5.2, 4.6.1 and 4.8.1 for Windows
• g++ 4.3 or later for Ubuntu 9.04 or later
• g++ 4.4 or later for Fedora 13 or later
• g++ 4.4 for Centos 6
• MacPorts g++ 4.3 to 4.8 on MacOSX Snow Leopard or later

All licences include a free upgrade to point releases, so if you purchase now you'll get a free upgrade to all 2.x releases of Just::Thread Pro. Purchasers of the older Just::Thread library (now called the compatibility library) may upgrade to Just::Thread Pro for a small fee.

Libc++ v5 PPA for Ubuntu now available

Monday, 11 September 2017

I am please to announce that I have made v5.0 of libc++ available for Ubuntu Linux via a PPA. Initially, the binaries are only available for Ubuntu 16.04 Xenial.

I was frustrated at the lack of an up-to-date build of libc++ for linux, especially with the v5.0 release of clang. Even though the LLVM project provide Ubuntu packages for clang, they don't provide one for libc++, and the version in the Ubuntu repositories is woefully out of date (v3.7). I therefore decided to package it myself, in this PPA.

This is especially good, since in combination with clang v5.0, it provides support for the Coroutines TS!

Enjoy!
