SQLColumns is in info.c, which should be in the distribution.

Wrong way to go. iODBC should _not_ be linked directly with your
psqlodbc image, because it has duplicate routines for every ODBC API! It
relies on explicit dynamic loading to find the psqlodbc routines at

You will need to find the linker options which force your psqlodbc
library to resolve all symbols internally. That way it won't be linked
back to iODBC at runtime (which happened to me on Linux). Don't know
what the options would be for Solaris; on Linux it is -Bsymbolic. I had
to include libc and libm in the link step to resolve the printf and pow
functions used by psqlodbc.

You will also need a decent ~/.odbc.ini file. Let me know if you don't
already have one...
