Usually something like ld -G -o myfile.so myfile.a [ this is platofmr specific, gcc uses -shared and AIX uses some horrible thing involve export/import maps and hex load addresses.. Urrgh!] Then you can do c4gl -o prog.4ge prog.4gl myfile.so Don't forget to set the environment variable SHLIB to point to the directory containing myfile.so. >FYI we are using ONLINE 7.23, 4GL 6.05. > >Malc (DBA, teaboy, scapegoat par excellence). > >-----== Posted via Deja News, The Leader in Internet Discussion ==----- >http://www.dejanews.com/ Now offering spam-free web-based newsreading -- David Williams Maintainer of the Informix FAQ Primary site (Beta Version) http://www.smooth1.demon.co.uk Official site http://www.iiug.org/techinfo/faq/faq_top.html I see you standin', Standin' on your own, It's such a lonely place for you, For you to be If you need a shoulder, Or if you need a friend, I'll be here standing, Until the bitter end...
