Do a man ld for ow to convert a normal .a library to a .so shared library. Something like ld -G -o mylib.so mylib.a or ld -shared -o mylib.so mylib.a usually works (don't ask what SCO or AIX need!) Then do c4gl -o mine.4ge....mylib.so You may need to set an enviroment variable to point to the directory where the shared library is stored. (LD_LIBRARY_PATH or SHLIB) the exact name varies from UNIX to UNIX. Also run c4gl and check if c4gl supports the -shared option. >Is any of the points possible ? > >Thanks, Michal > > > -- 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...
