Could you post a simple demo script ? I can't reproduce the problem.
I tried the following test script:
use strict;
use warnings;
eval {
require Inline; Inline->import (C => Config =>
BUILD_NOISY => 1);
require Inline; Inline->import (C =><<' EOC');
int foo() {
warn("Using Inline\n");
return 42;
}
EOC
};
# If Inline is unavailable, foo() simply calls
# the sub bar() pure perl implementation.
if($@) {
*foo =\&bar;
}
sub bar {
warn("Using Pure Perl Implementation\n");
return 42;
}
my $x = foo();
print "$x\n";
If I hide cc (gcc.exe in my case), the build fails for that reason, and
the script falls back to the pure perl implementation (sub bar).
This is as it's meant to be, and as it should be.
Cheers,
Rob
