Обсуждение: undefined reference to `ECPGconnect'

Hi all,
I haven't been able to figure out why I'm receiving this error.  Can someone
help me out?  It may be worth noting that in the generated file (after
preprocessing), I had to modify the prepended #include's to have 'pgsql' in
them (ie. #include <pgsql/ecpgtype.h>).
Thanks for any help!
Mark
