Windows Setup

General advice: Keep in mind that you need to spread the DLLs you link to along with your binaries for them to work on other systems.

GNAT Community 2020

• Download and install GNAT Community Edition x86 Windows (64bits) from AdaCore’s Download Site. This guide assumes you install it to C:\GNAT\2020. Make sure the bin folder is in the PATH of your shell.
• The FreeType library requires the Visual C++ Redistributable libraries for Visual Studio 2017. Download and install the x64 version from here and install it.
• Download and install OpenGLAda’s Windows installer from the repository’s releases section.
• While GLFW is a static library that is integrated into your binary, FreeType is a DLL located in C:\GNAT\2020\lib and must be spread along with your binary.

TDM-GCC 64bit

These instructions are for building 64bit binaries with TDM-GCC on Windows.

• Download and install the 64bit TDM-GCC compiler from here. In the installation wizard, make sure to check the (by default unchecked) ada option. Make sure the bin folder is in the PATH of your shell.

• Download the 64-bit Windows binaries from the GLFW download section (tested with GLFW 3.2.1).
• Open the zip folder and copy the file glfw3.dll from the lib-mingw-w64 folder into C:\TDM-GCC-64\lib.
• If you want to use FreeType, you need at least FreeType 2.7.1. There is an semi-official GitHub repository which hosts current Windows binaries known to work; get the freetype.dll file from the win64 folder and copy it into C:\TDM-GCC-64\lib.
• The FreeType library requires the Visual C++ Redistributable libraries for Visual Studio 2017. Download and install the x64 version from here and install it.

• Open your shell and navigate to the root folder of OpenGLAda. Execute:

   $ gnatmake -p -P opengl-test.gpr -XWindowing_System=windows
   $ gnatmake -p -P opengl-text-test.gpr -XWindowing_System=quartz
  

  This should produce executables in the bin folder inside OpenGLAda.

• You can now either add C:\TDM-GCC-64\lib to your PATH or copy the DLLs from there to the bin folder. One of those two options is necessary so that the binary can find the dll.
