Summary: freeglut segfault because it receives a __GLcontextModes
instead of a GLXFBConfig
Product: Mesa
Version: git
Platform: Other
OS/Version: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: GLX
AssignedTo: mesa3d-dev@lists.sourceforge.net
ReportedBy: ri...@free.fr
glXChooseFBConfig and friends happyly cast one structure to another, so I
believe they are supposed to be equal. This is not the case here, as gdb shows
it :
type = struct __GLcontextModesRec {
struct __GLcontextModesRec *next;
GLboolean rgbMode;
GLboolean floatMode;
GLboolean colorIndexMode;
GLuint doubleBufferMode;
GLuint stereoMode;
GLboolean haveAccumBuffer;
GLboolean haveDepthBuffer;
GLboolean haveStencilBuffer;
GLint redBits;
GLint greenBits;
GLint blueBits;
GLint alphaBits;
GLuint redMask;
GLuint greenMask;
GLuint blueMask;
GLuint alphaMask;
GLint rgbBits;
...
which comes from GL/internal/glcore.h from MESA, while the other is :
type = struct __GLXFBConfigRec {
int visualType;
int transparentType;
int transparentRed;
int transparentGreen;
int transparentBlue;
int transparentAlpha;
int transparentIndex;
int visualCaveat;
int associatedVisualId;
int screen;
int drawableType;
int renderType;
int maxPbufferWidth;
int maxPbufferHeight;
int maxPbufferPixels;
int optimalPbufferWidth;
int optimalPbufferHeight;
int visualSelectGroup;
unsigned int id;
...
This later definition comes not from MESA but aparently from
/use/include/GL/glxint.h on my host (which is a gentoo and this file is there
installed by a package named glproto BTW).
