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.
