Hello
I have recently installed R 2.14.2 on a brand new pc running Windows 64.
One of things I would like to do is to recompile my R package (with C and
fortran source codes) for this new environment (it works on a mac and on a
linux box). To this end, I had rtools 2.14 downloaded and installed (I
have also added 2.14.2/bin/x64 to PATH so that Rcmd works on a terminal).
On a cmd terminal I issue the command Rcmd INSTALL build name_of_my_package
to get
(x86 works fine)
*** arch - x64
cygwin warning:
MS-DOS style path detected: C:/PROGRA~1/R/R-214~1.2/etc/x64/Makeconf
Preferred POSIX equivalent is:
/cygdrive/c/PROGRA~1/R/R-214~1.2/etc/x64/Makeco
nf
CYGWIN environment variable option "nodosfilewarning" turns off this
warning.
Consult the user's guide for more details about POSIX paths:
http://cygwin.com/cygwin-ug-net/using.html#using-pathnames
gfortran -m64 -O2 -mtune=core2 -c correl.f -o correl.o
f951.exe: sorry, unimplemented: 64-bit mode not compiled in
make: *** [correl.o] Error 1
ERROR: compilation failed for package
What am I missing?
Many thanks
Ed
