If your machine is located behind a proxy server, make sure to check “Use Internet Explorer Proxy Settings” when you get to the “Select Your Internet Connection” step.

Cygwin’s setup wizard will walk you through a series of steps. Install Cygwinįirst, download and run either the 32- or 64-bit version of the Cygwin installer, depending on your version of Windows. Test the new GCC compiler in C++14 mode using the -std=c++14 option.

From within Cygwin, download the GCC source code, build and install it.Install a set of Cygwin packages required for building GCC.Install Cygwin, which gives us a Unix-like environment running on Windows.Depending on the speed of your machine, you can have the latest GCC up and running in as little as 15 minutes. You’ll need to compile GCC from sources, but that’s not a problem. The following guide will help you install the latest GCC on Windows, so you can experiment with generic lambdas and other cutting-edge C++ features. This feature is, however, available in the latest versions of GCC and Clang. Generic lambdas – also known as polymorphic lambdas – are one such feature. Set a breakpoint on the print() line and resume debugging.Several modern C++ features are currently missing from Visual Studio Express, and from the system GCC compiler provided with many of today’s Linux distributions.This is especially useful when debugging complex memory corruption problems:

You can navigate the Call Stack to view the Python code calling the C++ code and even the internal Python interpreter’s functions responsible for handling the calls.

Once the breakpoint hits, you will see both C++ and Python frames in the Call Stack and will be able to step through the method:

If you step into the hello() method, VisualGDB will actually step into the internal Python function used to call C++ functions, so instead, set a breakpoint in the HelloMethod() and press F5.

Once the breakpoint hits you will be able to look through the Python variables or step through the code:

Set a breakpoint in the Python script on the line calling the hello() method and press F5 to start debugging.

Build the module by pressing Ctrl-Shift-B:

VisualGDB will create a project consisting of a C++ Python module, a Makefile building the module using the Python includes and libraries and a simple Python script calling a function from the module.

On the last page of the wizard replace “python” with “python3” to explicitly select Python 3.x and press “Finish”:.

If it’s not auto-detected, select “specify a Cygwin-based toolchain manually” and point VisualGDB to its location:

Select the location of your Cygwin toolchain.

Select “Create a new project -> A Cygwin Python module”:.

Start Visual Studio and launch the VisualGDB MinGW/Cygwin Project Wizard:.

It also comes with pre-built Python 2.x and 3.x and we will show in this tutorial how to create a module that will be loaded into a Cygwin Python script.īefore you begin, install VisualGDB 5.1 or later and install Cygwin including the following packages: The Cygwin environment contains Windows ports for many Linux-based tools, so if you are porting a Linux application to run on Windows, it can prove time-saving by drastically reducing the porting effort. This tutorial shows how to develop C++ modules that can be loaded into Python scripts under Cygwin.
