[Radiance-general] genklemsamp.pl error on Windows

[Mostapha Sadeghipour]

Hi all,

I'm trying to run the 3 phase method to on Windows and there are some
problems with running genklemsamp.pl. Not to say that I'm using Andy's
tutorial as the reference.


If I run genklemsamp by defining window properties it works fine:

>> genklemsamp -vp 50 0 25 -vh 80 -vv 40 -vd 0 -1 0 > samplerays_1.dat


However it crashes if I pass a window geometry file:

>> genklemsamp.pl -vd 0 -1 0 window.rad

There is an issue with $tmploc on line 71 which is apparently only needed
for Windows systems. I tried to pass a different path to the variable as a
string but I couldn't solve the problem. Here is the lines 69-71.

if ($windoz) {
    my $tmploc = `echo \%TMP\%`;
    chomp($tmploc);
    ....

Anyone knows how can I get genklemsamp to work on Windows?

Thanks in advance,
Mostapha
