Perl Question

perl script lacking path for compiler - what compiler?

When following the openDDS install guide I attempt to run

configure
from within the command prompt but receive this output:

C:\Users\Supervisor\Desktop\opendds>C:\Users\Supervisor\Desktop\opendds\configure.cmd

Can't find a compiler, set PATH or run this script with the --compiler option.
For Microsoft Visual C++, run this script from the Visual Studio Command Prompt.
Stopped at configure line 336.


This error relates to this section of code within the perl script (as seen by the line number):

if ($opts{'compiler'}) {
my $standard = 0;
for my $stdcomp (@{$platforminfo{$opts{'host'}}->{'compilers'}}) {
$standard = 1 if $opts{'compiler'} eq $stdcomp;
}
$opts{'nonstdcompiler'} = 1 unless $standard;
}
else {
print "Auto-detecting compiler\n" if $opts{'verbose'};
for my $stdcomp (@{$platforminfo{$opts{'host'}}->{'compilers'}}) {
my $path = which($stdcomp);
if ($path) {
print "Found $stdcomp at: $path\n" if $opts{'verbose'};
$opts{'compiler'} = $stdcomp;
last;
}
}
if (!defined $opts{'compiler'}) {
die "Can't find a compiler, set PATH or run this script with the ".
"--compiler option.\n" . ($slash eq '\\' ? " For Microsoft Visual C++, ".
"run this script from the Visual Studio ".
"Command Prompt.\n" : '') . "Stopped";
}
}


What compiler does it want? I have
gcc
and
make
working - they are on the system path.

Answer

I suppose that windows does not list gcc as a naturally installed compiler.

On linux it would have worked right away.

So just add --compiler=gcc if gcc is in the path, it should work.
