Hi y'all,
I'm trying to find a way to do a CFLAGS+='-O' if and only if such a
parm was not already provided before 'make' actually runs.
I had this coded with the single = sign, i.e. without ?= or +=, but
the process still acts as if += was coded anyway, thus tacking on
my -O *after* the port's own CFLAGS.
GCC33 docs say the _last_ -O# is the one that will be used.
I've seen other discussion on using -O2 but the point seems to be the
ports that set -O2 explicitly are likely to work correctly.
And so, in many ports esp. KDE, it will add my -O *after* the port's
own -O2, and KDE et al will not be compiled with the intended
settings, which may be causing some of its slowness.
Since TPTB here could only find a spare [EMAIL PROTECTED] Pentium2 for this
project, I'm trying to optimize other ports with at least -O in an
automatic fashion. That leaves out /etc/pkgtools.conf due to the
sheer manual labor it would take to code this up for each port.
The idea of having a test in /etc/make.conf struck me as the way to
go, since it is effectively 'sourced'-in and could contain some simple
shell logic operations.
I hope I'm explaining this correctly. ;)
I'd love to hear feedback on this.
I'll continue working on it tomorrow.
Thank you,
