It sems to be suggesting that there's no typemap entry for 'double' - which
is a bit hard to believe.
Take a look in your /ExtUtils/typemap (same folder as Makemaker.pm) and
check that there is an entry for "double" in that file. Mine has:
.....
double T_DOUBLE
.....
INPUT
.....
T_DOUBLE
$var = (double)SvNV($arg)
.....
OUTPUT
.....
T_DOUBLE
sv_setnv($arg, (double)$var);
For an Inline::C check to see that there's no problems with passing and
returning doubles try:
###########################
use warnings;
use Inline C => Config =>
BUILD_NOISY => 1;
use Inline C => <<'EOC';
double foo(double x) {
return (double)x * 2;
}
EOC
print foo(17.3);
###########################
Cheers,
Rob
