Dear R package developers:
I need help on getting a package compiled for windows.
I am trying to use definitions and routines from a
set of libraries in that are in LINUX under
but these are unavailable in windows.
I found that we can get these by including, in windows these includes:
My problem is I do not know how to instruct the preprocessor to include
the linux .h files
when in linux and the windows one in windows.
I thought I found a solution online by using:
But I still get an error when these are compiled on the R-distribution.
I do not understand where I am supposed to set the Win32 flag so
that it will be ignored in LINUX but used in windows.
where is "Win32" "HAVE_UNISTD_H" and "HAVE_BSD_NETWORKING" set?
It seems that Makevars.win would be logical place, but
I do not see how to do this.
Thanks for any help.
