Dear developers,

I am trying to run some C/ Fortran code in R. Although I have experience with that in Windows (Vista) 32 bit, I could not succeed in 64 bit. I downloaded the following:
- R 2.12.0
- Rtools 212
- miktex 2.9
- inno setup 5

-Afterwards, I changed the path as:
‘C:\Program Files\R\R-2.12.0\bin;C:\Rtools\bin;C:\Rtools\MinGW64\bin;C:\Program Files\HTML Help Workshop;C:\Program Files (x86)\CodeBlocks\bin;C:\Program Files\Insight\bin;C:\Rtools\perl\bin;C:\Program Files (x86)\MiKTeX 2.9\miktex\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\Program Files\Broadcom\Broadcom 802.11\Driver;’

- started Command Prompt and checked the path by typing 'path'
- then I typed

'x86_64-w64-mingw32-gcc -c COXPHmatprod24delta.c -o COXPHmatprod24delta.o -I"C:\Program Files\R\R-2.12.0\include"'

the above command produced the file with .o extension. 

-Afterwards I typed 
'x86_64-w64-mingw32-gcc -shared -o COXPHmatprod24delta.dll COXPHmatprod24delta.o -I"C:\Program Files\R\R-2.12.0\include" -L"C:\Program Files\R\R-2.12.0\bin" –lR'

it produces the error: 
'x86_64-w64-mingw32-gcc: -lR: No such file or directory'

-The problem here is that it does not produce .dll file. I cannot find the solution to that although I tried for 2 days.   

--Alternatively I tried ‘R CMD SHLIB COXPHmatprod24delta.c’ and it produces the error:
'cygwin warning:
  MS-DOS style path detected: C:/PROGRA~1/R/R-212~1.0/etc/i386/Makeconf
  Preferred POSIX equivalent is: /cygdrive/c/PROGRA~1/R/R-212~1.0/etc/i386/Makec
  CYGWIN environment variable option "nodosfilewarning" turns off this warning.
  Consult the user's guide for more details about POSIX paths:
nm: not found
gcc -shared -s -static-libgcc -o COXPHmatprod24delta.dll tmp.def COXPHmatprod24d
elta.o -LC:/PROGRA~1/R/R-212~1.0/bin/i386 -lR
gcc: not found'

Every comment is appreciated. Many thanks in advance.

Sincerely Yours,
