Hello Stable@,
Compiling a kernel on stable/8 with DTrace support is failing with the
above subject line upon linking kernel.debug.
The text leading up to this is:
...
ctfconvert -L VERSION -g vers.o
linking kernel.debug
clock.o(.text+0x84c): In function `clkintr':
/usr/src/sys/x86/isa/clock.c:189: undefined reference to
`cyclic_clock_func'
And upon inspection of clock.c:
#ifdef KDTRACE_HOOKS
#include <sys/dtrace_bsd.h>
#endif
And in clkintr():
#ifdef KDTRACE_HOOKS
/*
* If the DTrace hooks are configured and a callback function
* has been registered, then call it to process the high speed
* timers.
*/
int cpu = PCPU_GET(cpuid);
if (cyclic_clock_func[cpu] != NULL)
(*cyclic_clock_func[cpu])(frame);
#endif
It seems for some odd reason that <sys/dtrace_bsd.h> is being forgotten
when it comes time for linking ? What is going on here ?
Id like to just remove the ifdef's for KDTRACE_HOOKS just to get the build
to finish but in the case that I want to build another kernel without
dtrace I would have to add them back. Anyone have a better fitting
solution to this ?
Would it be just as good to re-ifdef this to ?WITH_CTF? instead.
Anyway... this is latest code from stable/8 on i386. And yes options
KDTRACE_HOOKS is in the kernel config.
And the command that caused all this:
( make kernel WITH_CTF=1 )
