[gentoo-user] Per-package splitdebug FEATURE

[Leonardo Guilherme]

Hi.

I've turned on splitdebug feature (and -ggdb in CFLAGS) so debug
information are saved and I can debug anything that crashes. I went to
/usr/lib/debug, just out of curiosity, to see how much space was taken
and I found that it was almost 2GB, which chromium + firefox adds up
1.5GB and python gets another 0.3. I would like to disable splitdebug
for these specific packages now and in the future, so removing
splitdebug from features, re-emerging them and then activating
splitdebug again won't quite cut.

I wonder if there's a way to active features to some specific
packages, just like USE flags.

Thank you.

There is.  And it's a very powerful one even.  First, remove -ggdb (I 
use just -g though; if you don't need the extra info -ggdb gives, plain 
-g will save you some space and time) from your CFLAGS and splitdebug 
from your FEATURES in make.conf.  Then, create a file:

   /etc/portage/env/splitdebug.conf

with the following contents:

   CFLAGS="${CFLAGS} -ggdb"
   CXXFLAGS="${CXXFLAGS} -ggdb"
   FEATURES="${FEATURES} splitdebug"

Now, in /etc/portage/package.env, you can "execute" splitdebug.conf for 
the packages you want.  My package.env for example looks like:

   sys-libs/glibc splitdebug.conf
   media-libs/mesa splitdebug.conf
   kde-base/kdelibs splitdebug.conf
   kde-base/kwin splitdebug.conf

The result is that, for example, when glibc is emerged, splitdebug.conf 
is executed which adds -ggdb to CFLAGS and CXXFLAGS (do not forget 
CXXFLAGS!) and splitdebug to FEATURES.

As you can guess, you can create arbitrary .conf files like this; it 
isn't in any way specific to splitdebug.

Yes i think you can use /etc/portage/env for something like this 
for eg 
if you want to enable it for amarok 
create a file /etc/portage/env/media-sound/amarok 
with the contents 

CFLAGS="-march=core2 -O1 -g"
CXXFLAGS="${CFLAGS}"

FEATURES="splitdebug"

MAKEOPTS="-j3"

Thats what I call worthy information! Thank you so much, Yohan and Nikos!

What if I want to use splitdebug always and just deactivate it to some
packages, -splitdebug on FEATURES will undo the splitdebug already
set?
like

FEATURES="${FEATURES} -splitdebug"

Thanks again!

Another way is to enable splitdebug globally, but not install
debug files for specific packages :

   /etc/portage/env/do-not-install-debug-files.conf:

	INSTALL_MASK="/usr/lib/debug"

   /etc/portage/env/package.env:

	www-client/firefox do-not-install-debug-files.conf

If you are using FEATURES="buildpkg" you can set INSTALL_MASK into
make.conf : debug files will never be installed, but will be
available into tbz2 packages.

Sorry to resurect and old thread, but, its funny.

 I was searching for this information again and found a post in which this
guy was asking exactly what I wanted to know. Imagine my surprise when I
found that the guy was me but 4 years ago, I loled.

Thanks one more time!
