[gentoo-user] per-package CFLAGS
I have a package failing build (media-tv/mythtv). One resource on the
net suggests using the -fno-devirtualize gcc flag. Google tells me that
the way to do that would be something like
$ echo CFLAGS=\${CFLAGS} -fno-devirtualize\
/etc/portage/env/media-tv/mythtv
but the references are pretty old. Is this still the preferred way?
thanks,

[gentoo-user] per-package CFLAGS?
Am I understanding the docs correctly in that I can use /etc/portage/package.env to set per-package CFLAGS? -- Douglas J Hunley (doug.hun...@gmail.com) Twitter: @hunleyd Web: douglasjhunley.com G+: http://goo.gl/sajR3

Here is mine: app-emulation/virtualboxsafecflags.conf j1.conf app-office/libreoffice notmpfs.conf dev-lang/R j1.conf games-fps/alienarenanotmpfs.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 Wonko

awesome, thanks! Now I don't have to worry about graphite killing R or ppl anymore ;) On Fri, Apr 27, 2012 at 08:28, Alex Schuster wo...@wonkology.org wrote: Doug Hunley writes: Am I understanding the docs correctly in that I can use /etc/portage/package.env to set per-package CFLAGS?
