I prefer:
glGetShaderInfoLog(vertexShader, 512, null, infoLog.ptr);
That is a good tip to know.
I went through another tutorial. Changed the source code and left
out the shaders. I get another coloured background but still no
triangle. I have a feeling that
glBufferData(GL_ARRAY_BUFFER,
cast(int)g_vertex_buffer_data.sizeof,
cast(void*)g_vertex_buffer_data, GL_STATIC_DRAW);
in one example, or
glBufferData(GL_ARRAY_BUFFER, vertices.sizeof,
cast(void*)vertices, GL_STATIC_DRAW);
glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 3 *
GLfloat.sizeof, cast(GLvoid*)0);
in the other might be responsible, since they seem to be related
to drawing the triangle and I'm casting arguments in order to get
the program to compile.
(In the first line, glBufferData wants an int, and .sizeof
returns a uint, apparently.)
I'm sure there's something simple I'm missing but I just don't
have the experience to recognise it.
