Download GIT from http://git-scm.com/download/win

Git-2.14.2.3-64-bit.exe (or current version)
Just follow the installer with all its defaults.

start the Git CMD application

• git clone <repository link> for the first time

Download TDM-GCC from http://tdm-gcc.tdragon.net/download

32bit: tdm-gcc-5.1.0-3.exe

64bit: tdm64-gcc-5.1.0-2.exe (Make sure the 32 bit compiler is deinstalled.)

Just follow the installer with all its defaults.

git clone --recurse-submodules https://github.com/wxWidgets/wxWidgets.git

wxGraphicsContext is disabled by default for other compilers than Visual C++.
To enable it you just have to edit the "setup.h" file (in the include\wx\msw subfolder of the wxWidgets sources).
If the file is not present, make a copy of the one named "setup0.h" and name it "setup.h"
In this file, search for wxGraphicsContext.
You should find a section like the following (this is the wx-3.0.x version of the setup.h file):

// notice that we can't use wxCHECK_VISUALC_VERSION() here as this file is
// included from wx/platform.h before wxCHECK_VISUALC_VERSION() is defined
#ifdef _MSC_VER
#   if _MSC_VER >= 1310
        // MSVC7.1+ comes with new enough Platform SDK, enable
        // wxGraphicsContext support for it
#       define wxUSE_GRAPHICS_CONTEXT 1
#   else
        // MSVC 6 didn't include GDI+ headers so disable by default, enable it
        // here if you use MSVC 6 with a newer SDK
#       define wxUSE_GRAPHICS_CONTEXT 0
#   endif
#else
    // Disable support for other Windows compilers, enable it if your compiler
    // comes with new enough SDK or you installed the headers manually.
    //
    // Notice that this will be set by configure under non-Windows platforms
    // anyhow so the value there is not important.
#   define wxUSE_GRAPHICS_CONTEXT 0
#endif

Replace the last # define wxUSE_GRAPHICS_CONTEXT 0 by # define wxUSE_GRAPHICS_CONTEXT 1
Save and launch the build process and wxGraphicsContext should be enabled.

Open a terminal. (cmd.exe)

cd wxWidgets\build\msw
mingw32-make -f makefile.gcc BUILD=release UNICODE=1 MONOLITHIC=1 SHARED=0 USE_GUI=1 CXXFLAGS="-std=gnu++11"

After the build is ready, the libraries are found here:

wxWidgets\lib\gcc_lib

In the build setup.h file the wxUSE_GRAPHICS_CONTEXT must also be set to 1.
Path to the setup.h is:

lib\gcc_lib\mswu\wx\setup.h

See also Enable Graphics Context in the sources

As a prerequisite move the full wxWidgets directory from

Downloads\wxWidgets

to

\Users\<name>\wxWidgets

(or any path you may use)

Open a terminal and:

cd C:\Users\<name>\Rocrail
mingw32-make PLATFORM=WIN32 NATIVE=WIN32 DEBUG= MINGWINSTALL=C:\Users\<name>\wxWidgets

cd C:\Users\<name>\Rocrail
mingw32-make PLATFORM=WIN64 NATIVE=WIN64 DEBUG= MINGWINSTALL=C:\Users\<name>\wxWidgets

If another path for wxwidgets was chosen, then MINGWINSTALL= have to point the selected path.

After successful compilation the new build is located in

C:\Users\<name>\Rocrail\winbin

Move rocrail.exe, rocview.exe, all .dll and optional the svg directory in your operational Rocrail directory

Updates are only possible after the procedure from the scratch. The whole environment and a local git clone & build have to be in place.

Start the Git CMD application

cd C:\Users\<name>\Rocrail
git pull 

Open a terminal and:

cd C:\Users\<name>\Rocrail
mingw32-make PLATFORM=WIN32 NATIVE=WIN32 DEBUG= MINGWINSTALL=C:\Users\<name>\wxWidgets

cd C:\Users\<name>\Rocrail
mingw32-make PLATFORM=WIN64 NATIVE=WIN64 DEBUG= MINGWINSTALL=C:\Users\<name>\wxWidgets

If another path for wxwidgets was chosen, then MINGWINSTALL= have to point the selected path.

After successful compilation the new build is located in

C:\Users\<name>\(Projects)\Rocrail\winbin

Move rocrail.exe, rocview.exe, all .dll and optional the svg directory in your operational Rocrail directory

Sometimes debugging will create useful information for the developers, especially when there is a Rocrail server crash.
Building Rocrail from sources for debugging needs the same environment as described above.

Open a terminal and:

cd C:\Users\<name>\Rocrail
mingw32-make PLATFORM=WIN32 NATIVE=WIN32 MINGWINSTALL=C:\Users\<name>\wxWidgets

cd C:\Users\<name>\Rocrail
mingw32-make PLATFORM=WIN64 NATIVE=WIN64 MINGWINSTALL=C:\Users\<name>\wxWidgets

If another path for wxwidgets was chosen, then MINGWINSTALL= have to point the selected path.

After successful compilation the new debug build is located in

C:\Users\<name>\Rocrail\winbin

Open a console.

cd C:\Users\<name>\Rocrail\winbin
gdb --args rocrail.exe -l <your-dll-directory> -w <your-workspace-directory>

[example: gdb --args rocrail.exe -l c:\users\xxx\rocrail\winbin -w c:\users\xxx\documents\ROCRAIL\Taktplan_8_FPA5]

run

Open a console.

cd C:\Users\<name>\AppData\Local\Programs\Rocrail
gdb --args rocrail.exe -l C:\Users\<name>\AppData\Local\Programs\Rocrail -w <your-workspace-directory>
run

• After starting the server with this options start Rocview and the plan to test&debug should be presented.
  
• When the server crash occurs, switch immediately to the console windows and enter the cmd bt (which means backtrace)
  
• Copy the full information of the bt output into a editor, save the file and post it in the Rocrail Forum for analysis.
