You probably want to use word boundary anchors so that you don't get false positives with fprintf when looking for int etc. Also you might have more than one of your @prims on one line so a global match could be in order.

use strict;
use warnings;

my @prims = qw{ int char long double static };
my $rxPrims = do
   {
       local $" = q{|};
       qr{\b(@prims)\b};
   };

while ( <> )
{
    next unless my @found = m{$rxPrims}g;
    print qq{Found @found on line $.\n};
}

I hope this is useful.
