CPP compilation fails inside job::job

[jkeirstead]

I'm seeing an issue similar to #7. The brms demo runs fine within a normal console session, but when I wrap it with job::job, I get:

Compiling Stan program...
> 
> 
Error in .Call("rs_canBuildCpp") : 
  C symbol name "rs_canBuildCpp" not in load table
Calls: sourceWithProgress ... .fun -> cxxfunctionplus -> <Anonymous> -> check -> .Call

If I add opts = NULL or opts = list(buildtools.check = NULL, buildtools.with = NULL) to the jobs::job call, then the job runs.

Some debugging info:

Thanks for a great report! I've just uploaded a new version that sets some RStudio/RMarkdown-specific options to NULL. Could you try and install that and see if that solves the problem?

[jkeirstead]

Yup, that works! Thanks for the great package; I will be using this a lot.
