Ok. I apologise for not understanding. So, I have installed R-tools. It
changed my PATH-variable. I didn't installed Cygwin dlls as stated by
http://cran.r-project.org/doc/manuals/R-admin.html#The-Windows-toolset.
Instead my PATH-variable contains the path to the Cygwin dlls AFTER the
path to R... So, I started RTerm (32-bit) and tried > R CMD SHLIB mango.f95
and got the same error as earlier "Error: unexpected symbol in "R CMD"".
The same goes for RTerm (64-bit). Can you pls advice me on how to proceed?
Sincerely Jens
