[R] Still having a problem with Rcmd - TMPDIR

[Andy Bunn]

Hello R-users:

I'm experiencing difficulty in building a package in R 1.4.1 under Windows
2000. When I run Rcmd I get this:

F:\r\library>f:\r\bin\rcmd check ringsim
Please set TMPDIR to a valid temporary directory

F:\r\library>f:\r\bin\rcmd build ringsim
Please set TMPDIR to a valid temporary directory


This problem was discussed over a year ago - the problem was attributed to a
Perl bug. The CHECK file was amended in the build and indeed mine has the
line:

unless (-e $tmpdir);

It was thought that the -d was the bug. I added a print statement to CHECK
as per B. Ripley's suggestion:

$WINDOWS = ($OS eq "windows");
if($WINDOWS) {
    $TMPDIR = R_getenv("TMPDIR", "/TEMP");
    print "tmpdir is $tmpdir\n"; # added line
    die "Please set TMPDIR to a valid temporary directory\n"
      unless (-e $tmpdir);
    $R_exe = "Rterm.exe";
    $LATEX = "latex";
    $MAKE = "make";
}

The output is below:

F:\r\library>f:\r\bin\rcmd check ringsim
tmpdir is
Please set TMPDIR to a valid temporary directory

So it does indeed appear that there is no tmpdir. How can I set this
variable? The default temp directory on my machine is e:\temp but all other
applications see it. I'm running the latest perl (v5.6.1 built for
MSWin32-x86-multi-thread).

Any help appreciated.

Thanks in advance,
Andy
