in thread Exploring Inline::C (Generating primes)
OK, I see : the perl comments are included in the C source, and of course a line beginning with a # has unexpected effects there :) So adding a // in front of lines 137 and 164 saves the day:
perl test.pl 1..3 ok 1 - The first 501 primes are found from 1 to 3571. ok 2 - external_cpp() function gives same results as basic_perl(). ok 3 - inline_c() function gives same results as basic_perl(). # # Comparing basic_perl(), external_cpp(), and inline_c() for # 5 seconds searching 150000 integers. # Rate basic_perl external_cpp inline_c basic_perl 0.984/s -- -90% -96% external_cpp 9.45/s 860% -- -58% inline_c 22.6/s 2197% 139% -- # # I love it when a plan comes together. #
