When having per package environment settings modifyers, emerge --info does not show info accordingly to modifyed settings. To prove it: Have for example: /etc/portage/env/debug.conf CFLAGS="-O2 -pipe -march=core2 -flto -ggdb" CXXFLAGS="${CFLAGS}" LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--sort-common -Wl,-flto" CXXFLAGS_x86="${CXXFLAGS}" CFLAGS_x86="${CFLAGS}" LDFLAGS_x86="${LDFLAGS}" CFLAGS_x32="${CFLAGS_x86}" FEATURES="${FEATURES} splitdebug" /etc/portage/package.env (...) sys-libs/glibc debug.conf (...) emerge --info sys-libs/glibc | grep splitdebug (nothing is outputted) And emerge --info sys-libs/glibc | grep CXXFLAGS CXXFLAGS="-O2 -pipe -march=core2 -flto" CXXFLAGS_x86="-O2 -pipe -march=core2 -flto" CXXFLAGS="-pipe -march=core2 -O2 -fno-strict-aliasing" (in which -ggdb is not appearing) But there are other cases in which this is working, for example to disable LTO: /etc/portage/env/nolto.conf CFLAGS="-O2 -pipe -march=core2" CXXFLAGS="${CFLAGS}" LDFLAGS="-Wl,-O1 -Wl,--as-needed -Wl,--sort-common" CXXFLAGS_x86="${CXXFLAGS}" CFLAGS_x86="${CFLAGS}" LDFLAGS_x86="${LDFLAGS}" CFLAGS_x32="${CFLAGS_x86}" /etc/portage/package.env sys-process/numactl nolto.conf emerge --info sys-process/numactl | grep CXXFLAGS CXXFLAGS="-O2 -pipe -march=core2 -flto" CXXFLAGS_x86="-O2 -pipe -march=core2 -flto" CXXFLAGS="-O2 -pipe -march=core2" (note the last one without lto)
