Dear R users,
Thanks in advance.
I am using R 2.9.1 on Windows XP.
May I request you to assist me on the following:
I have downloaded Rtools29.exe and installed it today 02 Sep 2009 and I have also provided the appropriate path variable for Rtools.
I have checked the version of gcc compiler in Rtools.exe is 4.2.1.
I have checked (in http://gcc.gnu.org/) the latest available gcc compiler is 4.4.1. My objective is to use latest gnu gcc for openMP and I like to link it to R (by creating *.dll).
How can I use latest version of gcc for openMP? And at the same time I like to use Rtools as well.
I have moved this response to the R-devel mailing list, it's not really
appropriate for R-help.
Generally speaking the compiler used for a .dll need not be the same one
used for the rest of an application, so R won't care if you work out how
to use gcc 4.4.1 to build your dll. However:
- The scripts for building packages are written and tested against gcc
4.2.1; you may need to tweak them to work with a different compiler.
- As far as I know, there's no gcc 4.4.1 available for Windows, but
4.4.0 is available on the MinGW site. So if you really need 4.4.1 you
may need to compile it yourself.
So this is a pretty difficult project. You can ask on the R-devel
mailing list for help, but there aren't many people who will be able to
help you, so you may be pretty much on your own.

Once again, thank you very much for the time you have given.
I am looking forward for your reply.
Regards,
Deb
