Howdy, new to this list. I posted this to FreeBSD-users & was advised
to try this list or the GNU GCC list, so here goes:
I pkg-installed amd64-gcc over the weekend hoping for Graphite
(auto-loop parallelization) support, but no go. I looked around over
the weekend & found that there was no port for that package, only the
pkg. I just did a 'portsnap fetch upgrade' & there is now a port for
amd64-gcc, but it includes no files & no pkg-descr file. I determined
over the weekend that the gcc's from about V4.3 on can indeed be built
w/ Graphite support, but you need to do it manually. I found a post
dated 2010 from someone who did it under linux:
http://openwall.info/wiki/internal/gcc-local-build. I see no configure
files for any of the gcc ports (I have the entire ports tree
downloaded & local, & freshly updated as of a few min. ago). What is
the canonical/BPP (FreeBSD 9.3R) way of recompiling a port with
different config flags ?
I did find ports/pkgs for the 2 main components apparently needed for
Graphite support (cloog & ppl) & pkg-installed them over the weekend,
so I am ready to go on that front.
I have gotten as far as running 'make showconfig' in the various gcc*
& amd64-gcc directories to see what info I could get on default config
options. In all cases they gave options & said to run 'make config' to
change options. I didn't even see a 'config:' entry in the Makefiles
(probably included from elsewhere, but I didn't chase it). I only want
to make the minimum # of config mods necessary (trusting that pkg/port
maintainers probably know more than I about their various pkg's &
ports) to add the cloog & ppl support & recompile.
I have been using pkg almost exclusively to maintain my (now 3)
FreeBSD 9.3R boxen, except for recompiling the linux-c6 flash plugin
for this box whenever it get upgraded, so I have *no* experience with
getting more nitty-gritty w/ FreeBSD ports than that :-/. TIA & have a
good one.

i.e. no Graphite support. A few questions:
1. Is this list the proper forum for these questions :-) ?
2. Are ppl & cloog (both pkg-installed last wqeekend & ready to go) in
fact all that is req'd for Graphite support to work ?
3. Did the port of gcc4.9 wind up removing the req'd code internally for
Graphite support, so that even w/ the config properly setup, I still get
no Graphite support ?
This identical code (accessed via VPATH macro from Makefile over there)
compiles elsewhere on my LAN under Intel icc/ifort & parallelizes where
expected AOK. *Any* clues much appreciated. TIA & have a good one.
