Hello,

I am starting with the development of packages under Bioconductor... For the moment, I try to understand the construction of a package and for that, I try to compile "Rsamtools" that I take as an example.

But when I try to compile and install the package, I get this error message under Windows:

** R

** byte-compile and prepare package for lazy loading
** help

Exited with status 1.

But you can try to install an R package from source without problem, for example:

install.packages("jsonlite", type = "source")

What could be the problem? A problem of permissions?

With my thanks !
