[R-pkg-devel] problems with .mod files

These *.mod files are automatically created during compilation whenever 
there is a module in the corresponding source file. They should not be 
in the src folder of your package when you submit it to CRAN, but they 
should not be a problem when they get created in this folder during 
compilation.

Try to add the following line in .Rbuildignore (if this file does not 
exist, create it in the main directory of your package):

^.*\.mod

This will prevent R from including any *.mod files when building your 
package.

I hope this is helpful.

Best,

Remi

Hello,

I have been trying for weeks to get a package on CRAN, but keep
receiving warnings and notes, and errors using R-hub. The problems
started when I used FORTRAN code to speed up some functions. This
FORTRAN code introduces .mod files which are not accepted in the src
folder. I followed suggestions by Avraham Adler to clean the src folder
from this file by introducing a makefile with a clean command in it, but
then I get other errors, and above all, recently this solution did not
seem to remove the .mod file on some systems, as I still got the warning
that this file was found in the src folder (but not on my machine!).

So my question is: how do I prevent the creation of .mod files during
compilation of the FORTRAN code, or how do I tell R that these files are
OK in the src folder?

Regards,

Rampal Etienne
