Le compilateur n'a pas réussi à générer un fichier exécutable. (Erreur d'exécution)

Je suis récemment passé à OS Mountain Lion. Un projet sur lequel je travaille nécessite gem sys-proctable en tant que dépendance, mais lorsque je lance bundle install, je reçois:

Make sure that `gem install sys-proctable -v '0.9.2'` succeeds before bundling.

Mais j'ai des outils de développement installés! Lancer gem install sys-proctable -v '0.9.2' me donne presque la même erreur:

Il s’avère qu’il s’agit d’un bogue dans RailsInstaller OSX 1.0.3 - (Je l’ai découvert en lisant Les problèmes d’installation de Ruby sur Mountain Lion - Ruby 1.9.3 ne compileront pas )

Je devais changer /etc/rvmrc pour contenir ceci:

umask g+w
export -a rvm_configure_env
rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib' 'CFLAGS=-I/opt/sm/pkg/active/include' 'CPATH=/opt/sm/pkg/active/include')

Pour plus d'informations, voir: https://github.com/railsinstaller/railsinstaller-nix/issues/10

Le même problème s'est produit et je l'ai finalement résolu. Voici les étapes que j'ai suivies:

  • Xcode, Xcode CLT 
  • Sudo xcodebuild -license
  • Sudo port upgrade outdated
  • Sudo port install Apple-gcc42
  • rvm reinstall 1.9.3 #important!

Vraiment, je pense que juste les première, deuxième et dernière étapes requises, mais je ne peux pas le tester.

Assurez-vous d'ouvrir XCode après les mises à jour. J'ai découvert que je devais l'ouvrir et accepter le nouvel accord de licence après une récente mise à jour de XCode via l'App Store. Sinon, j'ai reçu le message suivant: "Le compilateur n'a pas pu générer un fichier exécutable. (RuntimeError) Vous devez d'abord installer les outils de développement."

Si vous utilisez rbenv et homebrew:

brew tap homebrew/dupes ; brew install Apple-gcc42

Les étapes suivantes ont résolu le problème.

  1. installation de xcode-select
  2. Sudo xcodebuild -license

J'espère que ça aide quelqu'un.

Parce que je suis sûr que je vais atterrir ici à nouveau.

Mon problème était que Sudo xcodebuild -license ne fait rien en fait et je devais démarrer manuellement xcode pour accepter leurs conditions d'utilisation. Quel OS glorieux.

Je recevais l'erreur suivante lors de "l'installation du paquet":

Après la mise à jour de Xcode et l’installation de CLT, procédez comme suit:

bundle clean --force

bundle install

Je ne saurais trop répéter à quel point c'était frustrant pour moi lorsque j'ai eu le même problème avec Mountain Lion. J'ai finalement mis à niveau mon système d'exploitation vers Mavericks après avoir lu qu'il y avait des problèmes avec GCC avec Mountain Lion. J'ai toujours eu la même erreur: /

La SEULE chose qui a fonctionné a été de réinstaller Ruby après avoir installé les outils de ligne de commande. 

"Pour les futurs visiteurs, cela a fonctionné pour moi. Ce n’est pas important, mais j’ai installé rvm avec brew. Xcode et Xcode CLT étaient déjà installés. Je devais simplement (pas de Sudo dans tout cela) rvm utiliser 2.0.0, puis xcode -license, acceptez la licence puis rvm réinstallez 2.0.0. dernière étape très importante "

Puis $ gem installe Rails

Cela corrige parfaitement mes problèmes. Ce blog est une très bonne solution pour installer des outils de développement Mac (outils de ligne de commande) de différentes manières ( http://www.moncefbelyamani.com/how-to-install-xcode-homebrew-git-rvm-Ruby). -on-mac/ )

Vous devez installer les derniers outils Xcode et de ligne de commande (à l'intérieur de Xcode) . C'est évidemment quelque chose avec votre Xcode ou votre PATH. Qu'est-ce que which clang donne?
