Hi Ryan, I did ``./mach bootstrap`` and the problem still happened with my VS 15.5 update.
I deleted the folders under my .mozbuild and do the bootstrap again but it seems useless... The errors are something like 9:58.83 c:\gecko-dev\obj-x86_64-pc-mingw32\dist\include\gtest/gtest-printers.h(878): error C4996: 'std::tr1': warning STL4002: The non-Standard std::tr1 namespace and TR1-only machinery are deprecated and will be REMOVED. You can define _SILENCE_TR1_NAMESPACE_DEPRECATION_WARNING to acknowledge that you have received this warning. and I did the bootstrap with the latest central(Bug 1423307 included). Can I do anything for troubleshooting? Thank you. 1. Firefox for Desktop Artifact Mode 2. Firefox for Desktop 3. Firefox for Android Artifact Mode 4.
