Summary: GLX header doesn't protect all functions
Product: Mesa
Version: unspecified
Platform: x86 (IA32)
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: GLX
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
As another user reported here:
http://www.nabble.com/--mesa3d-Bugs-1844243---GLX-header-definition-t4944614.html
In the header glx.h, all functions declarations are not encapsulated into the
consistent definitions (e.g. "#ifndef GLX_VERSION_1_x"). All defines are set at
the beginning of the header file ("#define GLX_VERSION_1_1 1", etc)
In a mixed environment where a project uses GLEW but depends on a library that
includes glx.h, they will get this error:
/usr/include/GL/glx.h:202: error: declaration of C function 'void
glXCopyContext(Display*, __GLXcontextRec*, __GLXcontextRec*, long unsigned
int)' conflicts with
/usr/include/GL/glxew.h:118: error: previous declaration 'void
glXCopyContext(Display*, __GLXcontextRec*, __GLXcontextRec*, GLuint)' here
The reason being that the types don't agree for the last parameter. I've filed
a bug with GLEW to fix this on their end:
http://sourceforge.net/tracker/index.php?func=detail&aid=1845264&group_id=67586&atid=523274
But I think it also makes sense to encapsulate the functions in glx.h, thus
this report.
