Can glyphy be made to run on Windows (for instance using Mingw?)

[Dann Corbit]

I can build the freetype library and other prerequisites.
But the glyphy project itself I am not sure about.

I have GPUs on all the machines I use.
I have AMD and NVIDIA GPUs.  Does it matter which kind is used?

Unfortunately, there appear to be two header files that are missing.  I cannot find them in the main tree or in the forked repository:

Those files are built using the autotools-based build system. I've attached
them for you.

Awesome, I have it working on Windows 64 bit now.  I was able to spin the block of text around, just like in your video.  It is completely clear to me that this is the correct way to process text in OpenGL and that the formation of texture blocks for characters is not the right way.

 

I really have to say something about how helpful you have been.

 

It is a little unusual for really intelligent people to be ultra-helpful (though that is an ideal combination).

By watching your video and explanations, it is clear to me that you are very smart.

And you are also incredibly helpful.  It is a rare combination (like professor William Kahan of Berkeley as another example) to find someone with both admirable qualities.

 

If everyone was as helpful as you are, the world would be a better place.

Thanks again.

Subject: Fwd: Can glyphy be made to run on Windows (for instance using Mingw?)

[Dann Corbit]

Here is a link to a working package for Windows 64 bit, if other people want to experiment:
https://www.dropbox.com/s/drfi9hcv9xqb3bp/windows-glyphy-package.7z?dl=0

In order to make it work on your system, you will need to make the following changes:

1.  Change PKGDATADIR to match your system.  On mine, I set it like this in two places:
#define PKGDATADIR "F:\\project\\dcorbit\\glyphy-master\\src"

2.  The library paths for linking freeglut and glew will need to be corrected for your system

It could be made a lot simpler and more automatic, if someone wants to bother with that.  I guess that MSYS2 could be used to automate for the Mingw environment it just like on Posix systems.  I made a Microsoft Visual Studio version instead.
