[Nix-dev] GCC in pkgs.buildEnv.paths

Sun May 25 10:12:50 CEST 2014

Here is what I see (this is a diff of references of gccWrapper for gcc vs.
testgcc):

hey, who are you?
~~~~~~~~~~~~~~~~~~~~~~~~~~

I didn't know how to diff .drvs either, so I used a command like

~~~~
nix-store -q --references <path_to_drv_in_store> | sort -t - -k2
~~~~

to produce a list of references sorted by derivation name. Then `diff` plus
some hand-juggling to make the diff look nicer.
