Dear R Help,
My apologies if this is widely known, but I didn't find this in the R archives.
I am running WinXP pro and R 1.90. Rcmd build or check fails with the error: "Please set TMPDIR to a valid temporary directory"
OK. So why do you not set an environment variable TMPDIR=C:\Windows\temp (which is the standard temp directory on Windows XP)?
Uwe Ligges
$TMPDIR is set to $TMPDIR or C:/TEMP in share\perl\R\Var.pm. TMPDIR or c:\temp do not exist on WinXP on my laptop. I have C:\WUTemp and the env variables $TMP and $TEMP are set (..Is this normal?).
The two work arounds I found are to create a C:\temp directory, or include $TMP or $TEMP in Var.pm. I did the latter, and it works for me. I include the fix below.
if($OSTYPE eq "windows"){
## DON'T add R_HOME/bin here: it might contain spaces and will not
## work using system() under Windows 98. $R_EXE = "Rterm.exe";
$R_CMD = "Rcmd.exe";
getenv("TMPDIR", "TMP", "TEMP", "C:/TEMP"); # Edited to include TMP and TEMP
print "tmpdir is $TMPDIR\n"; # Edited to include print
if (-d $TMPDIR) {
$TMPDIR = Win32::GetShortPathName($TMPDIR) if $TMPDIR =~ / /;
$TMPDIR =~ s+\\+/+g; ## ensure forward slashes only
} else {
$TMPDIR = "" }
}
