GLUT still runs when user closes window

One question, is that DLL a translation of the library from C to Delphi, and recompiled with Delphi? I don't understand why none the DLLs provided in the GLFW website work with Delphi applications, since those are supposed to be win32 libraries. :?

I found this:

Can't get OpenGL apps to work in Linux

Notify me of responses

I am unable to run any OpenGL applications on RedHat9, the cause might
be GLUT, when i run any FPC or Kylix compiled project that uses GLUT
they display an error about X.. function. I don't have any apps that
use OpenGL directly. I adapted the GLFW unit from
http://glfw.sourceforge.net/ to be crossplatform and i was able to run
GL progs on windows but not on linux, i also linked the C code to so.
I would appreciate some help in running OpenGL apps on Linux.
The C/C++ based examples also Quake 3 run verry well.

Answers:

I had the same problem. I tried to use GLUT but it didn't work. Then I tried to use GLX but it didn't work neither. Now, I'm using SDL and this works verry well. SDL is a libery wich can be used to set up an OpenGL window. SDL is available for many platforms. If you want to use it in FreePascal, you can use the Jedi-SDL headers.

So it seems, after all, that I'll have to give a try to SDL, since GLFW is not available for FPC on Linux at the moment. Another dead-end :lol:

Wha? Rats. Their website is out of date then, since it claims to be cross platform. Oh well.

It's cross-platform, yes... but that's for C, not for Pascal at the moment.

I think what's missing are FPC's headers, because the headers provided by the GLFW team are based on a DLL, which won't work on Linux AFAIK. Someone should write or modify the headers to work with Linux libraries. I would do it, but I'm just a newbie at FPC and Linux.
