I have a strange problem. Sometime ago I used -flto flag to boost optimisation and used it in my make.profile. Then I removed it. Now I have: -O2 -march=native -fomit-frame-pointer -pipe After some time I recompiled GCC without LTO support so now -flto flag is no longer supported by the compiler. Now I want to rebuild dev-db/postgresql-server. But whatever I do old CFLAGS are picked up: -O2 -march=native -fomit-frame-pointer -flto -pipe. And of course nothing rebuilds because GCC has been compiled without LTO. My question is: is it a bug or a strange feature? Old CFLAGS seem to be stored somewhere and used. Even after I removed dev-db/postgresql-server and tried to build it from scratch.

As you can see CFLAGS contain -flto although I removed it months ago.
# pg_config --cflags -mschedule=8000 -march=2.0 -ggdb -pipe -Wall -O2 -Wno-comment -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wmissing-format-attribute -Wformat-security -fno-strict-aliasing -fwrapv -fexcess-precision=standard
Ok, I just serached for all packages that I compiled with -flto and did not recompile since CFLAGS change. It seems that postgresql-server used CFLAGS from postgresql-base. (In the way that pg-server queries pg-base for CFLAGS and uses them instead of CFLAGS I specified). I think this is a bug. If I compile pg-server and pg-base with different CFLAGS set - this should be my own problem. But silently using different CFLAGS configuration was the last thing I expected. If there is really a need for CFLAGS to match, then maybe pg-base should be simply always forcibly selected for recompilation (when someone compiles pg-server)? POINT-A: GCC compiled with -flto support edited CFLAGS to include -flto POINT-B: compiled pg-base compiled pg-server POINT-C: recomiled GCC and dropped -flto support removed -flto from CFLAGS POINT-D: due to ebuild change, need to recompile pg-server cannot recompile, because pg-server uses outdated CFLAGS (POINT-B)
I had a similar problem. I tried changing CFLAGS on the postgresql-server install, but the original CFLAGS were somehow stuck and I wasn't able to change them. I traced my problem to this line in the ebuild script: eval econf "$(${PO}/usr/$(get_libdir)/postgresql-${SLOT}/bin/pg_config --configure)" \ which effectively means that no matter what you pass in, the build is just going to run pg_config --configure to see how the package was last compiled and use that for the installation (and thus overwriting everything you had passed in). My "fix" was to move the /prefix/usr/lib/postgresql-9.3 out of the way, so that ebuild couldn't find pg_config at all, then install. On that installation, the correct CFLAGS were used (since they weren't overwritten by pg_config) and I could then delete the original (moved) /lib/postgresql-9.3 directory, as the install recreated the directory anyway. But yes, I agree either this behavior is a bug, or the lack of warning that your optimization parameters are being ignored is a bug. HTH, Robert
This is a symptom of using the split ebuilds. The real solution is to rebuild dev-db/postgresql-base, the package that builds and installs pg_config. It is both a bug and a feature. dev-db/postgresql-server must be built using the same flags that were used when building dev-db/postgresql-base. The bug is in the way we handle things. Eventually I'm going to merge the ebuilds back into one. Until then, this will not be fixed.
*** Bug 524324 has been marked as a duplicate of this bug. ***
dev-db/postgresql (the unified ebuilds) have been committed to the tree, along with virtual package, and dependencies have been updated. The solution is to use the new, unified ebuilds.
