[R-pkg-devel] Bug? Makevars ignores FC=mpif90

[Ignacio Martinez]

Thanks peter.

1. Does it say anywhere that the build process should use src/Makevars?
I'm not sure, where should it say that? I'm using the default options in
Rstudio to create a package

2. Also notice that an important part of the package concept is that
packages can be distributed.
The package that i want to build uses MPI. Is that a problem? My
understanding is that in order to use MPI i have to set FC to mpif90. Is
that wrong?

3. build configuration belongs in the build environment
I'm not sure if I follow. What is the correct way of telling Rstudio that
the package i'm building uses MPI?

Thanks again!
