use flags

[pavel.stratil]

Hi all!

I wonder, the prebuilt binaries have all useflags enabled? what about i.e. the debug flag?

thanks!

No, they don't. You can check the situation of each package yourself by using the eix utility:

Code: Select all

# equo install git
# emerge --sync
# layman -a sabayon
# equo install eix
# eix-update
# eix <package name>

If you don't want to install eix, you can also use equo for the same purpose, just run:

Code: Select all

equo query installed --verbose <package-name>


for example:

Code: Select all

equo query installed --verbose wget

it gives you some more detail, like amd64 or multilib.

Everything is build with split-debug.
You can enable a setting in Entropy to also install debug files.

/etc/entropy/client.conf

Code: Select all

# Enable the installation of debug files
# Also known as "splitdebug" support
# Valid parameters: disable, enable, true, false, disabled, enabled, 0, 1
# Default parameter if unset: disable
# splitdebug = disable
# HOW SPLITDEBUG WORKS with Entropy
# Once you enable the "splitdebug" feature
# you just need to (re)install packages in order to
# get /usr/lib/debug metadata files installed. That's it.
# You can safely remove /usr/lib/debug without affecting
# Operating System functionality, at any time.

thanks for the explanations! just to make sure, for standard useflags enabling/disabling features at build time: if equo or the http://packages.sabayon.org/show/wget,55777,sabayonlinux.org,amd64,5,standard/#package-widget-show-what site tell

Code: Select all

USE flags:       amd64 elibc_glibc ipv6 kernel_linux
                      multilib nls ssl userland_GNU


then these are the useflags the binary is build with and if I want for example (eix output on gentoo)

Code: Select all

[I] net-misc/wget
     Available versions:  1.12-r2 1.12-r3 {debug idn ipv6 nls ntlm +ssl static}
     Installed versions:  1.12-r3(08:55:02 PM 05/04/2011)(idn ipv6 nls ssl -debug ntlm -static)
     Homepage:            http://www.gnu.org/software/wget/
     Description:         Network utility to retrieve files from the WWW


the ntlm flag enabled, i have to use portage for that particular package/useflag combination, right?

[Fitzcarraldo]

Yes.

cool! now, having skimmed through the docs, esp. http://wiki.sabayon.org/index.php?title=HOWTO:_Safely_mix_Entropy_and_Portage, i have a suggestion on enhancing entropy:

why not make entropy /equo also a wrapper for portage and flaggie? it would be, imho, awesome, it you could install packages with equo as usual and for the special cases when you would have to use portage, use equo with a --build-source or whatever parameter which would take care of properly setting stuff in /etc/portage and masking things in /etc/entropy and installing system dependencies with equo first when such are required?
