Dear followers,

One of the target platform for GPAC is Windows. Developing for Windows in a comfortable manner requires Visual Studio, in particular for debugging. Microsoft recently announced great changes that will make Visual Studio users (including the GPAC developers) happy:

*  Visual Studio Community Edition replaces the Express Edition. [It is very complete for development][].
 *  6 weeks ago, Microsoft [open-sourced their GDB/LLDB front-end][open-sourced their GDB_LLDB front-end] for [Visual Studio 2015][]. It means that we can now debug gcc-built programs with the Visual Studio debugguer interface.

Setup for local debugging

Install software:

*  Install [Visual Studio 2015][]. Install the “Tools for Visual C++ Mobile Development” in a sub-menu (disabled by default).
 *  Install gdb/gdbserver. Use [MinGW-w64 binaries][] and put them in your PATH (you can rely on the [excellent MSYS2][] for a full development environment).  
    /!\\ Legacy MinGW and Cygwin gdb binaries are known to fail /!\\

Build:

*  Use your usual build system and gcc or clang compiler. Don’t forget to enable debugging!

Debugging:

*  In your command-line, launch:

    That’s all! Once Debug.GDBLaunch is attached your program will run. Breakpoints are effective. And you can enjoy the Visual Studio debugging experience:
