[cfe-dev] [lldb-dev] Should we stop supporting building with Visual Studio?

I build with the VS project. I find it more convenient to do that than have VS and a cmd window open to run ninja. Especially when I’ve got more than 1 copy of VS open looking at different release trains. I wouldn’t mind using ninja to build, but only if it worked when I right click on lldb and select “Build”.


Our buildbots use msbuild on the project, like this:

call "c:/Program Files (x86)/Microsoft Visual Studio 14.0/VC/vcvarsall.bat" x64 & msbuild ALL_BUILD.vcxproj /m /property:Configuration=Release

I don't know any more about this. It would be good to know more than 
that it can "apparently fail sometimes".


Sadly that's part of the problem.  Very few people actually use the Visual Studio generator for building, so a lot of times when we get people with issues, nobody knows how to help (or the person that does know doesn't see the thread).  So they get a response like "hmm, not many people actually use that workflow, can you try this instead?"


I feel bad when I can't help, and that's part of why I made this proposal in the first place, because fewer supported options in the configuration matrix means people are more likely to find someone who understands the problem when something goes wrong.
