A couple things:
The value you pass to WITH/WITHOUT/NO variables in src.conf(5) or
make.conf(5) rarely has purpose. The make.conf(5) manpage documents
this fact:
The following lists provide a name and short description for each vari-
able you can use during the indicated builds. The values of variables
flagged as bool are ignored; the variable being set at all (even to
``FALSE'' or ``NO'') causes it to be treated as if it were set.
Thus, the following lines are all synonymous in functionality (disabling
profiled libraries):
WITHOUT_PROFILE=yes
WITHOUT_PROFILE=true
WITHOUT_PROFILE=no
WITHOUT_PROFILE=aphuvudet
WITHOUT_PROFILE="the ape is watching"
However...
I don't quite understand the profiling framework for src/. There are
numerous variables referenced, such as MK_PROFILE, and I also see a
couple references to NO_PROFILE (which should be a RELENG_6 and below
thing?).
I also see this in src/Makefile.inc1, which makes me wonder if profiling
support is broken altogether:
391 _libraries:
392 @echo
393 @echo "--------------------------------------------------------------"
394 @echo ">>> stage 4.2: building libraries"
395 @echo "--------------------------------------------------------------"
396 ${_+_}cd ${.CURDIR}; \
397 ${WMAKE} -DNO_FSCHG -DWITHOUT_HTML -DWITHOUT_INFO -DNO_LINT \
398 -DWITHOUT_MAN -DWITHOUT_NLS -DWITHOUT_PROFILE libraries
Note the unconditional use of the -DWITHOUT_PROFILE flag.
Anyone familiar with this framework who can comment on what the state of
things is?
