[Nix-dev] nix-shell ignores custom configurePhase/buildPhase etc.?

[Bjørn Forsman]

Hi,

Why doesn't a custom configurePhase (or buildPhase, installPhase etc.)
work when run from nix-shell? In nix-shell, all phases seem to be the
default, even if the derivation has customized some of them.

Take the openscad expression as an example. It has this configurePhase:

  configurePhase = ''
    export NIX_CFLAGS_COMPILE="$NIX_CFLAGS_COMPILE -I$(echo
${eigen}/include/eigen*) "
    qmake PREFIX="$out" VERSION=${version}
  '';

But when run in nix-shell, it ignores this custom configurePhase:

$ nix-shell -A openscad
warning: you did not specify `--add-root'; the result might be removed
by the garbage collector
$ unpackPhase
unpacking source archive
/nix/store/qbw1m3adaz1ayhvgj99iyi3qisp08biz-openscad-2013.01.src.tar.gz
source root is openscad-2013.01
$ cd openscad-*
$ configurePhase
no configure script, doing nothing

Best regards,
