From: Jo-Philipp Wich Date: Wed, 26 Jul 2017 22:18:12 +0000 (+0200) Subject: scripts/package-metadata.pl: inhibit compile deps on missing build types X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=bf5d32af2a675f7577b388b5eef2a11e6ce042eb;p=librecmc%2Flibrecmc.git scripts/package-metadata.pl: inhibit compile deps on missing build types When a package declares a PKG_BUILD_DEPENDENCY or HOST_BUILD_DEPENDENCY on a not existing build type, the metadata script will emit a reference to an unresolvable build target in tmp/.packagedeps, causing the make process to fail hard in a way not catchable by the IGNORE_ERRORS mechanism. In a situation where a package "test-a" declares a build dependency "PKG_BUILD_DEPENDS:=test-b/host" while the Makefile of "test-b" does not implement a HostBuild, make fails with an unrecoverable error in the form: make[1]: Entering directory '...' make[1]: *** No rule to make target 'package/test-b/host/compile', needed by 'package/test-a/compile'. Stop. make[1]: Leaving directory '...' .../toplevel.mk:200: recipe for target 'package/test-a/compile' failed make: *** [package/test-a/compile] Error 2 Extend the metadata generation script to catch such unresolved references and emit a visable warning upon detection. After this change, the script will emit a warning similar to: WARNING: Makefile "package/test-a/Makefile" has a build dependency on "test-b/host" but "package/test-b/Makefile" does not implement a "host" build type Fixes a global build cluster outage which occured after the "python-cffi" feed package removed its HostBuild which the "python-cryptography" package build-depended on.
