Hi, I am trying to build swift-3.1-branch from github (https://github.com/apple/ swift) on my new Macbook Pro with OS Sierra v10.12.6. I get the following error during doc generation using the command "sudo ./swift/utils/build-toolchain local-swift":
""" [4193/4193] cd .../swift/docs && /usr/local/bin/sphinx-build -D latex_paper_size=letter -d .../build/buildbot_osx/swift-macosx-x86_64/doctrees -b html . .../build/buildbot_osx/swift-macosx-x86_64/docs/html FAILED: docs/CMakeFiles/docs_html cd .../swift/docs && /usr/local/bin/sphinx-build -D latex_paper_size=letter -d .../build/buildbot_osx/swift-macosx-x86_64/doctrees -b html . .../build/buildbot_osx/swift-macosx-x86_64/docs/html Running Sphinx v1.6.3 WARNING: unknown config value 'latex_paper_size' in override, ignoring .... generating indices... genindex writing additional pages...

Please also report this if it was a user error, so that a better error message can be provided next time. A bug report can be filed in the tracker at <https://github.com/sphinx- doc/sphinx/issues>. 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 """ 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. I get the above error with -W enabled. I have Sphinx 1.6.3 installed on my machine and Cmake 3.9.0 It seems like incompatible sphinx version? Has anyone seen this error with latest code? --Raj
