I'll have to undo this patch... I said that you must export both symbols when GCC version is the right one. And I can say this version is > 3.3.4, since my good Gentoo's 3.3.4 does not include this symbol. We rediscussed this with Jeff, and I'll post a better patch: EXPORT_SYMBOL(__gcov_init), and weakly define it to an empty function. I'll do it tomorrow. > Signed-off-by: Jeff Dike <[EMAIL PROTECTED]> > > Index: linux-2.6.11/arch/um/kernel/gmon_syms.c > =================================================================== > --- linux-2.6.11.orig/arch/um/kernel/gmon_syms.c 2005-03-07 > 10:53:03.000000000 -0500 +++ > linux-2.6.11/arch/um/kernel/gmon_syms.c 2005-03-07 16:29:37.000000000 -0500 > @@ -5,8 +5,14 @@ > > #include "linux/module.h" > > +#if __GNUC__ > 3 || (__GNUC__ == 3 && __GNUC_MINOR__ > 3) || \ > + (__GNUC__ == 3 && __GNUC_MINOR__ == 3 && __GNUC_PATCHLEVEL__ >= 4) > +extern void __gcov_init(void *); > +EXPORT_SYMBOL(__gcov_init); > +#else > extern void __bb_init_func(void *); > EXPORT_SYMBOL(__bb_init_func); > +#endif > > /* > * Overrides for Emacs so that we follow Linus's tabbing style. -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
