Celestia 131 (Linux CVS) crash

Hello Celestia community,

I compiled celestia from today's CVS on linux, QT 3.2.1, KDE 3.1.4, and installed Walton Comer's 32k virtual BlueMarbel earth texture.

Celestia starts up ok, but crashes when selecting BlueMarbel DDS as alternate surface on earth. Dump looks like this:

I tried to debug, and it seems that glx::glCompressedTexImage2DARB contains 0 instead of a valid function pointer, but now I'm lost.

I have a Radeon 9600 graphics card and use ATI's XFree86 drivers (fglrx 3.2.5, XFree 4.2.0, Kernel 2.4.21). I use the libGL that comes with this driver. glxinfo gives

Ok, answering to my own post:

I narrowed things down by modifying Celestias source code. I can avoid the crash with the following dirty hack in src/celengine/glext.cpp:

Code: Select all

+ extern "C" void glCompressedTexImage2DARB(GLenum target, GLint level,
+     GLenum internalformat, GLsizei width, GLsizei height,
+     GLint border, GLsizei imageSize, const GLvoid *data);

  static void InitExt_ARB_texture_compression()
  {
  #if defined(GET_GL_PROC_ADDRESS)
      glx::glCompressedTexImage3DARB =
          (glx::PFNGLCOMPRESSEDTEXIMAGE3DARBPROC)
          GET_GL_PROC_ADDRESS("glCompressedTexImage3DARB");
      glx::glCompressedTexImage2DARB =
          (glx::PFNGLCOMPRESSEDTEXIMAGE2DARBPROC)
          GET_GL_PROC_ADDRESS("glCompressedTexImage2DARB");
+     if (glx::glCompressedTexImage2DARB == 0)
+         glx::glCompressedTexImage2DARB = glCompressedTexImage2DARB;
      glx::glCompressedTexImage1DARB =
          (glx::PFNGLCOMPRESSEDTEXIMAGE1DARBPROC)
          GET_GL_PROC_ADDRESS("glCompressedTexImage1DARB");
      glx::glCompressedTexSubImage3DARB =
          (glx::PFNGLCOMPRESSEDTEXSUBIMAGE3DARBPROC)
          GET_GL_PROC_ADDRESS("glCompressedTexSubImage3DARB");
      glx::glCompressedTexSubImage2DARB =
          (glx::PFNGLCOMPRESSEDTEXSUBIMAGE2DARBPROC)
          GET_GL_PROC_ADDRESS("glCompressedTexSubImage2DARB");
      glx::glCompressedTexSubImage1DARB =
          (glx::PFNGLCOMPRESSEDTEXSUBIMAGE1DARBPROC)
          GET_GL_PROC_ADDRESS("glCompressedTexSubImage1DARB");
  #endif // GL_ARB_texture_compression
  }


With this loading the .dds texture works fine (wow, earth in 32k is really impressive!). This by far is no real solution, but sheds some light.

I'm no OpenGL expert, so I wonder why GET_GL_PROC_ADDRESS("glCompressedTexImage2DARB") gives 0, although a working glCompressedTexImage2DARB is in libGL.so

Anyone know how to fix this correctly? Is it an ATI driver bug? Are there ways to workaround properly?

Thanks for comments,
Wolfgang
