Not exactly "minimally reproducible". Do tell beforehand than cloning the
repo will suck down 300+ megabytes. And that you have build requirements for
other packages exotic enough that they are NOT met by the reverse depends of
the now almost 1100 packages I test against. Not nice. And after I wasted
all that time it STILL failed because you have an unsatisfiable depends in
'rwind'. Did you mean rWind?
When I then re-generate the exports via `compileAttributes()` I now get
Warning messages:
1: Unable to parse C++ default value 'numeric_limits<double>::infinity()' for
argument max_h of function hef2
2: Unable to parse C++ default value 'numeric_limits<double>::infinity()' for
argument max_h of function hef_list
That is
a) likely an issue an our end we will try to fix for Rcpp 0.12.13
b) something you should have caught, but likely didn't because your build
already generated pages and pages of compiler warnings
c) something you can work around locally, eg via a file local const
As a test, I just removed the argument from the function interface and it
worked fine.
Thanks for the report though. But next time, __please__ try to submit
something __minimally reproducible__ and not a blob requiring the
installation of 15 other packages and a download of 300mb.
