[gentoo-user] emerge --update --newuse too eager?

[Helmut Jarausch]

Hi,

would anybody please be so kind to explain to me how
emerge --update --newuse --deep @system @world
works.

E.g. it wants to  re-emerge sys-devel/gcc because of the
"new use flag nptl"  according to

[ebuild   R   ] sys-devel/gcc-4.4.0  USE="nptl%*" 
[ebuild   R   ] sys-devel/gcc-4.3.3-r2  USE="nptl%*" 

But, looking at the corresponding ebuild files they don't
use (IUSE or other) such a use flag.
But why then does emerge want to rebuild those packages.?

(I'm using portage 2.2_rc33)

Many thanks for an explanation,
Helmut.

It's from an inherited eclass:

# grep inherit *
gcc-4.3.3-r2.ebuild:inherit toolchain
gcc-4.4.0.ebuild:inherit toolchain
nazgul gcc # grep nptl /var/portage/eclass/toolchain.eclass
        IUSE="multislot nptl test"
                confgcc="${confgcc} --disable-__cxa_atexit --enable-target-
optspace $(use_enable nptl tls)"

nptl USE flag comes from toolchain.eclass.  Almost all the work for the
ebuild is done in the toolchain.eclass for gcc.

nptl flag was recently added to enable thred local storage for
nptl/uclibc users:

--deep (rebuilds the compiler)  and it looks like you've built two versions
of GCC in the past.
