[Nix-dev] glibc-2.13 hell

[Sergey Mironov]

Hi. I've updated my system first time after stdenv-update merge. Now I have

[ierton at greyblade:~]$ nix-dev-revision nixos
9c3a31f

[ierton at greyblade:~]$ nix-dev-revision nixpkgs
0caed13

base revisions for nixos and nixpkgs, plus some custom packages in nixpkgs.

Unfortunately, I've ran into situation I can't explain: it turns out that
some packages depends on glibc-2.13 while we now have glibc-2.17 as the
default. Here is how it looks like:


[ierton at greyblade:~]$ opera
Fontconfig warning:

(last 'Failed to load library's are opera issues, probably they are not
related to the topic)

Well, I've tried to check this and it is for real:

[ierton at greyblade:~]$ nix-store -q --references
/nix/store/3q5h1p4zbbgia5w8m6c31182zdkhavrn-opera-12.12-1707 | grep glibc
/nix/store/cj7a81wsm1ijwwpkks3725661h3263p5-glibc-2.13

BUT

[ierton at greyblade:~]$ readlink `which firefox`
/nix/store/svg5hcg1ygn6953x9wzvpr9dr4rkh6ji-firefox-19.0.2-with-plugins/bin/firefox

[ierton at greyblade:~]$ nix-store -q --references
/nix/store/svg5hcg1ygn6953x9wzvpr9dr4rkh6ji-firefox-19.0.2-with-plugins
/nix/store/yw62q6acrpjnx2r1zg9bzsn7xld1y00s-bash-4.2-p42
/nix/store/7m7na8ikagc2qsanr9zf1vvs3n732cn1-firefox-19.0.2
/nix/store/gbji6vix2xp35aczvxrnks9s8h0q4ya2-flashplayer-11.2.202.273
/nix/store/hfmgq39bv6099wap4hracmp2wa83h576-jdk-1.6.0_38b04

[ierton at greyblade:~]$ nix-store -q --references
/nix/store/7m7na8ikagc2qsanr9zf1vvs3n732cn1-firefox-19.0.2 | grep glibc
/nix/store/zpr8jdx10napidkyz62f3nzl5fm87jyr-glibc-2.17

So, firefox depends on good glibc, but opera depends on bad glibc. Any
ideas what is going on?

Regards,
Sergey

PS I had custom libfreetype  in the LD_LIBRARY_PATH (set by the
~/.bash_profile) at the moment of nixos-rebuild, like this:

[ierton at greyblade:~]$ echo $LD_LIBRARY_PATH
/nix/store/zwilpkw86liih06x1zg6avlkd17awyfn-freetype-2.4.10/lib:/run/opengl-driver/lib:/run/opengl-driver-32/lib

Could that be the cause?
