Hi, I see some OS X builds have been failing for some weeks in the configure step with
configure: error: C compiler cannot create executables See `config.log' for more details Eg this fails: http://hydra.nixos.org/build/30904978 But eg this one works: http://hydra.nixos.org/build/30853497 Examining config.log: configure:5019: checking for gcc configure:5046: result: clang [...] configure:5315: checking whether the C compiler works configure:5337: clang -O1 conftest.c >&5 xcode-select: error: no developer tools were found at '/Applications/Xcode.app', and no install could be requested (perhaps no UI is present), please install manually from 'developer.apple.com'. That seems like a general problem that should be fixed? Independent of that, is there a way to specify gcc in a release.nix file? Thanks.
