vr_messages.pb.h and .cc not being generated

[nickludlam]

I have an issue during the build process where I end up with no vr_messages.pb.h and vr_messages.pb.cc. This happens for each project where there's a dependency on those files.

It looks like there's a pre-compile script failure, and I see a warning saying warning: directory does not exist on line 1. Unfortunately I'm not as familiar with vpc as I'd need to be to debug this further, but it seems like an invocation of protoc is failing somewhere. Can I see any trace logging of what's bombing out?

Thanks, Nick

What platform are you building on?

Apologies, should have included that! I'm on Windows 7 64-bit and have both VS2010 and 2012 installed

I've grabbed the build output and made a gist. https://gist.github.com/nickludlam/11229375

From what I can tell, it has an issue as my users directory has a space in it, so in the output there's a line:

C:\Users\Nick : warning : directory does not exist.

instead of it being C:\Users\Nick Ludlam\. Can it be that spaces are not being escaped somewhere in the build process?

[JoeLudwig]

That is almost certainly what it is. Does if you copy the whole directory into something that doesn't have a space then run VPC and try to build?

The fix is likely to add \" around the $SRCDIR/whatever references in https://github.com/ValveSoftware/steamworks-vr-api/blob/master/src/vpc_scripts/protobuf_builder.vpc

[nickludlam]

Yeah I can build it just fine when I move the repo out of its default directory in Documents. I'll have a go at patching the protobuf_builder.vpc file to see if I can get it accepting SRCDIR paths with spaces

[nickludlam]

I couldn't find a good way to escape the path so I'm not sure if this should be noted down in the README as a gotcha, or whether someone else wants to have a go at fixing it.

I've done this before in batch scripts using SET SRCDIR="C:\Something with spaces\" and then reference it with %SRCDIR% but I'm unclear about the context in which the generated code gets run.

Added a note to the readme to hopefully keep other people from running into this.
