Qt 5.4 released

From the news article:

I am happy to announce that Qt 5.4 has been released today and is available for download from qt.io. Together with Qt 5.4, we have also released Qt Creator 3.3 and an update to Qt for device creation on embedded Linux and embedded Android.

But let’s start with Qt 5.4. One of the main focus areas of this Qt release has been around Web technologies and we have a lot of cool new things to offer there...

Tutorial to develop a client side web application in C++ with PNaCl -- Chrome Developer Guide

By miltonm | Dec 10, 2014 08:19 AM | Tags: None

In case you missed it, now you can develop web apps in C++ to run natively on Google Chrome. This tutorial shows how to develop a Native Client module in C++ and build and run it using PNaCl toolchain:

C++ Tutorial: Getting Started (Part 1)

This tutorial shows how to build and run a web application using Portable Native Client (PNaCl). This is a client-side application that uses HTML, JavaScript and a Native Client module written in C++. The PNaCl toolchain is used to enable running the Native Client module directly from a web page...

Portable Native Client or PNacl, which is supported on Google Chrome at the moment, lets you compile and run native code developed in C or C++ within a secure sandbox in browser. PNaCl uses the LLVM toolchain to generate OS-independent and architecture agnostic intermediate bytecode which is later loaded, translated and executed by the browser. To get more information on PNaCl and it's less portable companion NaCl check the native client developer documentation.

Why Students Need the CppCat Code Analyzer

by Andrey Karpov

CppCat is a simple static code analyzer capable of detecting bugs in C/C++ programs. We started granting free academic licenses to all interested (students, teachers, and so on). For the sake of popularizing CppCat among students, I decided to write this post about errors that can be found in student lab work tasks posted at Pastebin.com...

OpenMP* Support in Clang/LLVM: Status Update and Future Directions --Alexey Bataev & Zinovy Nis

By Razvan Pascalau | Dec 8, 2014 05:33 PM | Tags: openmp intermediate compiler clang

A status update for the work done on OpenMP for Clang/LLVM and future directions presented at the 2014 LLVM Developers' Meeting. The slides are also available here.

OpenMP* Support in Clang/LLVM: Status Update and Future Directions

OpenMP is a well-known and widely used API for shared-memory parallelism. Support for OpenMP in Clang/LLVM compiler is currently under development. In this talk, we will present current status of OpenMP support, what is done and what remains to be done, technical details behind OpenMP implementation. Also, we will elaborate on accelerators and pragma-assisted SIMD vectorization, introduced in the latest 4.0 edition of the OpenMP standard.

More support for creating all-C++ Android applications:

Developing Native-Activity (Android) applications in Visual Studio 2015

by Ankit Asthana

From the article:

Visual Studio 2015 preview (download here) introduces the ability for developers to create Android Native Activity application as a part of the cross-platform mobile development. Android platform with Android Native Activity (API Level 9) introduced the capability to create pure C/C++ applications. While there is some hidden Java JNI code in the background the idea is to abstract this detail away from the developer. Native Activity applications are popular for gaming (e.g. Unreal 4) and graphic intensive (OpenGL) applications. This post will guide you through the experience of creating a Native Activity application and walking through the developer lifecycle of editing, building and debugging Native Activity code...

Background: The Android NDK was first released in 2009 offering the possibility to use C++ code in Android applications. Since NDK 5 (released in Dec 2010) it is even possible to create a complete native Android app in C++ but even with the continuous improvements of the SDK/NDK it was easier to develop Android applications in Java than in C++.

E.S.R. Labs presents its STL library adapted to embedded environments and discusses some of the choices they made for it:

C++ STL for Embedded Developers

by John Hinke

From the article:

C++ embedded programming is very difficult. There are some limitations that are not always present in traditional programming environments such as limited memory, slower processors, and older C++ compilers.

We have developed a set of best-practice processes and frameworks to support writing high-quality embedded applications...
