Hey guys,
Not sure if you guys are using a beta version of redhat or any other
setup using a 2.96+ release of gcc, but if so...
It seems they are implementing a new optimization that is on by default
in the compiler that doesn't allow symbols to be resolved correctly in
the X module loader. The optimization is "merge-constants". Until this
is fixed in the module loader, you may pass -fno-merge-constants to gcc.
Here are some things to change, per a post on xfree86-devel:
The host.def settings are:
/*
* The following changes are required in order to disable gcc's new
* 'merge-constants' optimization, because the XFree86 module loader is
not
* yet aware of the new ELF sections it produces, and will cause module
* loading to fail. - [EMAIL PROTECTED]
*/
#define NeedModuleRanlib YES
#define ModuleCFlags \$(CDEBUGFLAGS) \$(CCOPTIONS) -fno-merge-constants
\
\$(THREAD_CFLAGS) \$(ALLDEFINES)
#define ModuleRanlibCmd RanlibCmd
And the needed patch to enable the above functionality (which was
previously limited only to OS2 builds) is attached.
