Hi, I am trying to build swift-3.1-branch from github ( https://github.com/apple/swift) on my new Macbook pro with Sierra v10.12.6. I get the following error during doc generation which I use the command sudo ./swift/utils/build-toolchain local-swift:

Thanks! ninja: build stopped: subcommand failed. ./utils/build-script: fatal error: command terminated with a non-zero exit status 1, aborting ./utils/build-script: fatal error: command terminated with a non-zero exit status 1, aborting """" Earlier I was getting an error with -W option to sphinx which I disabled in the CMakeLists.txt file, but then get stuck with the above error. With -W option enabled, the error was : "WARNING: unknown config value 'latex_paper_size' in override, ignoring". I do see that this variable is set in CMakeLists.txt. It seems like incompatible sphinx version? Has anyone seen this error? --Raj
