nss will not configure without gyp: Building NSS requires an installation of gyp: https://gyp.gsrc.io Google's build-file generator, which nss uses to produce its ninja files. It is a real Arch package and a Python program, so it joins the Python set. jsoncpp is the fourteenth instance of this shape and the sixth of my own making. Removing the doxybuild.py call stopped the API html being generated; package() still copied the directory it would have produced, and the name carries pkgver so the path is not greppable without knowing the version. The rule is mechanical enough now to state as a procedure rather than a lesson: after removing a documentation build, grep package() for the OUTPUT directory name, not for the tool. The tool appears in build(); the path appears in package(), and it is the path that fails. --- FR --- nss ne se configure pas sans gyp : Building NSS requires an installation of gyp: https://gyp.gsrc.io Le générateur de fichiers de construction de Google, dont nss se sert pour produire ses fichiers ninja. C'est un vrai paquet Arch et un programme Python : il rejoint l'ensemble Python. jsoncpp est la quatorzième occurrence de cette forme, et la sixième de ma main. Retirer l'appel à doxybuild.py a arrêté la génération du html d'API ; package() copiait toujours le répertoire qu'il aurait produit, et son nom porte pkgver — le chemin n'est donc pas trouvable par grep sans connaître la version. La règle est assez mécanique pour être énoncée en procédure plutôt qu'en leçon : après avoir retiré une construction de documentation, chercher dans package() le nom du répertoire de SORTIE, pas celui de l'outil. L'outil est dans build() ; le chemin est dans package(), et c'est le chemin qui échoue. Assisted-by: Claude Opus 5
