Bug 403775 – sci-libs/openfoam-2.1.0 ignores CFLAGS

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Richard Yao (RETIRED) 2012-02-15 04:51:35 UTC]

I was compiling OpenFOAM on Gentoo Prefix on RHEL 6.2 and noticed that it is ignoring my system CFLAGS:

g++ -m64 -Dlinux64 -DWM_DP -Wall -Wextra -Wno-unused-parameter -Wold-style-cast -Wnon-virtual-dtor -O3  -DNoRepository -ftemplate-depth-100 -I/home/stonybrook/gentoo/var/tmp/portage/sci-libs/openfoam-2.1.0/work/OpenFOAM-2.1.0/src/finiteVolume/lnInclude -I/home/stonybrook/gentoo/var/tmp/portage/sci-libs/openfoam-2.1.0/work/OpenFOAM-2.1.0/src/lagrangian/basic/lnInclude -I/home/stonybrook/gentoo/var/tmp/portage/sci-libs/openfoam-2.1.0/work/OpenFOAM-2.1.0/src/lagrangian/dsmc/lnInclude -I/home/stonybrook/gentoo/var/tmp/portage/sci-libs/openfoam-2.1.0/work/OpenFOAM-2.1.0/src/meshTools/lnInclude -IlnInclude -I. -I/home/stonybrook/gentoo/var/tmp/portage/sci-libs/openfoam-2.1.0/work/OpenFOAM-2.1.0/src/OpenFOAM/lnInclude -I/home/stonybrook/gentoo/var/tmp/portage/sci-libs/openfoam-2.1.0/work/OpenFOAM-2.1.0/src/OSspecific/POSIX/lnInclude   -fPIC -Xlinker --add-needed -Xlinker --no-as-needed Make/linux64GccDPOpt/dsmcFoam.o -L/home/stonybrook/gentoo/var/tmp/portage/sci-libs/openfoam-2.1.0/work/OpenFOAM-2.1.0/platforms/linux64GccDPOpt/lib \

(JFYI, The fact that it is Gentoo Prefix is not relevant)

[Comment 2 Benj FitzPatrick 2012-10-04 22:46:12 UTC]

I tried compiling openfoam-2.1.1 with gcc-4.7.2 and LTO and found the same results. My build.log has lots of -O3, but no -O2, -pipe, or -flto anywhere.

[Comment 3 Jonas Stein 2017-10-29 15:16:59 UTC]

Confirmed by Benj FitzPatrick.

[Comment 4 Michał Górny 2019-10-31 15:36:50 UTC]

Package removed.
