@INC:
/MODAPSint/lib
/usr/local/lib/perl
/usr/local/lib/perl
/usr/local/lib/perl
/usr/local/lib/perl
/usr/local/lib/perl
/usr/local/lib/perl
That's a rather unusual @INC.
Somewhere within your perl installation (not exactly sure where it
will be on your particular build) you should find an
ExtUtils/typemap. On my linux box, the file is in
/usr/local/lib/perl5/5.8.4/ExtUtils/typemap.
That file should contain an entry for "double".
Normally, in the process of building PDL, that typemap would be found
by default. If, for some reason, that's not happening (or the typemap
doesn't contain an entry for "double"), then I guess you could end up
with the error message you're seeing.
Have you built many other perl extensions (modules) on that build of
perl ? Any troubles with them ?
Does the following Inline::C script work for you ? (It should, if you
have Inline::C installed):
------------------------------------
use warnings;
use strict;
use Inline C => Config =>
BUILD_NOISY => 1;
use Inline C => <<'EOC';
double foo(SV * x) {
return (double)SvNV(x);
}
EOC
my $x = 1.25;
print foo($x);
------------------------------------
If that does run ok for you, then you can ignore pretty much
everything I've written. (ie the typemap I referred to is being found
and is in good shape.)
Cheers,
Rob
I do see the typemap, with "double" defined:
[EMAIL PROTECTED]:~ % grep double /usr/local/lib/perl/ExtUtils/typemap
double T_DOUBLE
$var = (double)SvNV($arg)
sv_setnv($arg, (double)$var);
sv_setnv($arg, (double)$var);
It looks like Inline is NOT installed: does it need to be?
[EMAIL PROTECTED]:~ % ./scr.pl
Can't locate Inline.pm in @INC (@INC contains: /MODAPSint/lib
/usr/local/lib/perl /usr/local/lib/perl /usr/local/lib/perl
/usr/local/lib/perl /usr/local/lib/perl /usr/local/lib/perl .) at
./scr.pl line 7.
BEGIN failed--compilation aborted at ./scr.pl line 7.
Also, I wonder if this has something to do wtih how I am trying to
install things. We have a perl distribution installed in
/usr/local/lib/perl, with PDL installed there as well, but with
WITH_BADVAL turned off. So I am trying to build a new version of PDL
with WITH_BADVAL turned on, and a few extra goodies to experiment with,
but installed in my home directory (since I do not have permission to
install to /usr...). Perhaps the build is getting mixed up as to where
to find things. I invoked the build with
perl Makefile.PL --prefix=/home/gederer/usr
but perhaps I need to edit Makefile.PL and mess with some environment
vars, since I do not have perl installed in my home directory?
Thanks,
--greg
