Compiling C-code in Windows

Hello ALL!
I am an Linux user (Debian testing i386), with very dusty
Win-experience. Nevertheless, my colleagues and I are making some
package in R, and I built C-routines to speed up things.
I followed instruction how to compile C for R (very useful link:
http://www.stat.lsa.umich.edu/~yizwang/software/maxLinear/noteonR.html,
and links listed there). Everything works like a charm in Linux. I have
*.so and wrapper function from R is doing a right call.
However, I wanted to make *.dll library for Win-users. Now, I used my
colleague's computer with Win XP on it, and with the latest R. In MS-DOS
console, I positioned prompt in 'C;\Program Files\R\R-2.13.0\bin\i386\',
and then I run: 'R CMD SHLIB C:\trial.c'. However, nothing happened, no
trial.dll, nothing. Then, I tried with: 'R CMD SHLIB --output=trial.dll
C:\trial.c', but no luck, again.
Please, can anyone help me with this? Can I use: 'R CMD SHLIB
--output=trial.dll C:\trial.c' under Linux, and expecting working DLL?

Best,
PM

Re: Compiling C-code in Windows

You could use cygwin's cc/gcc, or the Watcom opensource compiler.

[Watcom used to be a commercial compiler which ceased and has
become an open project].

But listen to people who've experienced the options. [Not I].

Cheers, Tom.

You should follow the instructions in the R Installation and
Administration manual to set up the tools on your Windows system.

Really nothing? Not even an error message?

Then, I tried with: 'R CMD SHLIB --output=trial.dll

I assume you mean "under Windows". I would normally use a forward
slash, i.e. C:/trial.c; I don't remember if the R CMD code handles
backslashes. (It might treat \t as a tab.) With that change, this
should work.

One piece of unsolicited advice: I would hardly ever use R CMD SHLIB.
Just include the C code in a package, and this is handled automatically
by R CMD INSTALL. You won't need the .First.lib if you have a
useDynLib() statement in your NAMESPACE.

Hi Petar,

did you install the toolset (Rtools) for compiling code for R in
windows? See

http://cran.r-project.org/doc/manuals/R-admin.html#The-Windows-toolset

and

http://www.murdoch-sutherland.com/Rtools/

> Please, can anyone help me with this? Can I use: 'R CMD SHLIB

Of course not, because Windows and Linux libraries differ by more than
the filename extension.

Once everything is set up, compiling in windows is pretty easy thanks to
the toolset.

Good luck,

Andreas

Neither of those is supported. Use what the R Admin manual suggests, or
you're on your own.

I have had fairly good luck with cygwin or mingw but you may need to
have a few conditionals etc. Not sure what R suggests but cygwin should
work.

The MinGW compilers are the recommended ones. If you use Cygwin, you'll
need to provide the Cygwin DLLs as well, and those may clash with others
on the user's system, so I wouldn't recommend it.

Re: Compiling C-code in Windows

Try

CC=gcc -mno-cygwin

to avoid linking with the Cygwin dlls.
