Hello.
I installed VampyreImaging library from online package manager.
I used function LoadGLTextureFromFile to load a texture from bmp file
and this give SIGSEGV. Is there other ways I can load texture?

How are you calling  LoadGLTextureFromFile? Do you have a call
stack/backtrace?
Looking at the function signature and knowing you're getting a
segfault, I suspect that you might be passing invalid pointers as 
CreatedWidth  and  CreatedHeight. It should be something like this:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var 
Texture: GLuint;  Width, Height: LongInt;begin  Texture :=
LoadGLTextureFromFile('tex.bmp', @Width, @Height);  // Width and
Height now contain the bitmap's dimensionsend;

Falling even when I call it this way LoadGLTextureFromFile('tex.bmp',
@Width, @Height).
