WITH_CTF can now be specified in src.conf (not recommended, there
are some problems with static executables), make.conf (would also
affect ports which do not use GNU make and do not override the
compile targets) or in the kernel config (via "makeoptions
WITH_CTF=yes").
Additional (related) changes:
- propagate WITH_CTF to module builds
- do not add -g to the linker flags, it's a noop there anyway
(at least according to the man page of ld)
- do not add -g to CFLAGS unconditionally
we need to have a look if it is really needed (IMO not) or if there
is a way to add it only when WITH_CTF is used
Note: ctfconvert / ctfmerge lines will not appear in the build output,
to protect the innocent (those which do not build with WITH_CTF would
see the shell-test and may think WITH_CTF is used).
Excellent -- I'm really glad to see this getting sorted out at last.
I think there's a reasonable argument that we should be compiling
options KDTRACE_HOOKS into GENERIC, and likewise enabling CTF on the
kernel by default in 9.x. Part of the point of DTrace is that it
"just works", and we already compile CDDL modules by default (and
the hooks don't affect the license of the base kernel as far as I'm
aware). Any thoughts on this?
I'm in favour of this. You just need to commit 2 lines for GENERIC
(and one for NOTES, I think)...
Bye,
Alexander.
