[Perfinsp-list] Dpiperf driver build problems on Fedora 11/G5

[Maynard J. <may...@us...>]

Hi, Milena,
I've encountered a couple of problems trying to build the driver on a PPC970 PowerMac G5 running rawhide (Fedora 11 alpha release).  I am using source code that I pulled down earlier this week.  This source builds fine on a SLES 10 POWER5 system.

1. "gcc: -pg and -fomit-frame-pointer are incompatible"
This appears to be something that gcc 4.4 catches.  I removed the -fomit-frame-pointer from the EXTRA_CFLAGS in the driver Makefile to get around this problem.

2. "pi_init_mm_address undeclared"
I get this error on Fedora 11 because the kernel is 2.6.29, so we end up trying to use that symbol at line 329 of pi_btrace.c:
		#if LINUX_VERSION_CODE > KERNEL_VERSION(2,6,99)
		        struct mm_struct * p_init_mm = (struct mm_struct *)pi_init_mm_address;
		#else
			struct mm_struct * p_init_mm = &init_mm;
		#endif

The driver Makefile generates pi_init_mm_address into the hooks.h file, but only on x86.  How should this be fixed for other arch's?

Thanks.
