Just to add to this, something I haven't seen neatly documented but I personally find very helpful (if a bit rough) is to run "genericBuild" from within nix-shell, which will run the phases from the derivation... and usually fail to install during installPhase. I often start this and then just interrupt it during the build so I can poke at the source or config.log or whatever.
Anyway, it is an easy way to say "just do what nix-build does" for unknown derivations. Doesn't let you re-use the bits and install into the nix store, but usually that's much less of an issue--once I have a thing working I don't mind rebuilding (in fact, it's /good/ to rebuild from scratch before saying "ship it") one final time. ~Will PS: nix-shell doesn't set NIX_BUILD_CORES so I often do something like 'NIX_BUILD_CORES=8 genericBuild' (or whatever) On Fri, Mar 17, 2017 at 2:26 PM, Profpatsch <m...@profpatsch.de> wrote: > On 17-03-17 06:04pm, Volth wrote: >> "nix-shell" would be a super option here if it could handle >> "installPhase" (this seems easy to fix) and .nix files less trivial >> than "hello.nix" (this seems not easy to fix; for example "nix-shell >> '<nixpkgs>' -A linux_4_4" has no "configurePhase", and there are >> similar problems with almost every of the big projects; nix-shell >> launches "make" when "nix-build" launches "cmake" or vice-versa, etc) > > That’s a pretty common stumbling block. > > If someone defines his own `installPhase` for example, > the `installPhase` shell function is just the standard > stdenv `installPhase`.
