Static and dynamic link

Hello cgicc gurus,

I have a problem with dynamic link on my Fedora Core 3. If I compile the 
program in this way
g++ test.cpp -o test.cgi /usr/lib/libcgicc.a
the script works OK and displayes  the desired page on my httpd server.
But if I compile the program in this way
g++ test.cpp -o test.cgi -lcgicc
the browser isses message


  Internal Server Error

And in the error_log is this message
[Thu Nov 25 17:48:27 2004] [error] [client 127.0.0.1] Premature end of 
script headers: test.cgi, referer: http://localhost/cgitests/cgitest.html
Thank you for a help
