Created attachment 14182 [details] fix for parser.read() in llvmbuild.componentinfo Hi, while building llvm i got the message llvm-build: error: invalid native target: 'x86' all the time. In the end, LibraryDependencies.inc was missing and the build failed. My environment: Gentoo default/linux/amd64/13.0 python-2.7 (default) all packages are more or less not older than 2 months I tracked it down to the RawConfigParser which is not used properly: parser.read(path) <- expects a list of file_names not a string https://docs.python.org/2/library/configparser.html#ConfigParser.RawConfigParser.read A patch is attached.
