[gentoo-user] per-package CFLAGS?

[gentoo-user] per-package CFLAGS?

[Doug Hunley]

Am I understanding the docs correctly in that I can use
/etc/portage/package.env to set per-package CFLAGS?

Yes, and it's quite easy. Here is mine:

app-emulation/virtualbox	safecflags.conf j1.conf
app-office/libreoffice		notmpfs.conf
dev-lang/R			j1.conf
games-fps/alienarena		notmpfs.conf
games-fps/worldofpadman		notmpfs.conf
games-puzzle/pingus		safecflags.conf
games-sports/vdrift		notmpfs.conf
mail-client/thunderbird		notmpfs.conf
sys-boot/grub			grub.conf
sys-libs/glibc			nosandbox.conf
www-client/firefox		notmpfs.conf

These *.conf files are located in /etc/portage/env/, and they are just
shell scripts sourced by emerge. For example, j1.conf simply has the line
'MAKEOPTS=-j1' in it, this disables parallel makes for some packages
where I had trouble with it. Similarly, notmpfs.conf has
'PORTAGE_TMPDIR=/var/portage/tmp', while my normal PORTAGE_TMPDIR is on
tmpfs. 5G sometimes is not enough for the big packages. grub.conf has
'export DONT_MOUNT_BOOT=foo', this disables mounting the /boot directory
and doing stuff there when emerging it again. I already forgot about this
one. And nosandbox.conf has 'FEATURES=-usersandbox', as recent glibc does
not build here with this setting. 

Any finally my savecflags.conf:
  CFLAGS="-pipe -march=amdfam10 -O2"
  CXXFLAGS=$CFLAGS

awesome, thanks!

Now I don't have to worry about graphite killing R or ppl anymore ;)
