I'm new in D, so i'm tried to write some in that langugage.
That's story about how i tried to port OGL sample, that renders
one triangle.
I was very surprised when i found, that D doesn't have equivalent
of gl/gl.h. Any C++ compiler has it.
Okay, i'm investigate in it and found OpenGL in deimos.
It doesn't support a lot of OGL function such as glPushMatrix and
others.
Okay, then i found derelict3. It has a lot of OGl functions and
it's okay.
When i tried to rewrite example to D, i was shocked.
core.sys.windows.windows doesn't have a lot of functions. It
doesn't contain simple function DestroyWindow for example.
It's intresting, but go ahead, i found derelict.util.wintypes
with missing functions. I've got a lot of "conflicts with"
errors, because some of functions was in derelict's wintypes too.
I've solved it. When i tried to link my program, i've got a lot
of "undefined reference" errors. Okay, i've built and link
derelict libraries. Then errors became stranger:
DerelictUtil.lib(traits) Offset 204C4H Record Type 0091
Error 1: Previous Definition Different : _D67
DMD\windows\bin\..\..\src\phobos\std\traits.d.17012__ModuleInfoZ
So i can't to rewrite simple OpenGL example that consists of 50
lines.
This example works on every C++ compiler without building/finding
any libraries.
Dlang's standard windows.h heade is useless, because a lot of
functions/structs definitions is missing.
Dlang is a toy in outer space.
One can only to write a+b program in schools on it.
Now i'm understand, that's why D doesn't have popularity after
10+ years of existence.
