One thing to be careful about when gluing together a bunch of different libraries written in C from different sources is to use the same compiler options everywhere. That's true on most platforms but there are some VMS-specific wrinkles to worry about, such as floating point format (different defaults on Alpha and Itanium), case-preserved linker symbols (or not), name mangling options for names longer than 32 characters. >Talking of which: > >Our previous release of the odbc-odbc bridge (to access remote ODBC >drivers from OpenVMS) linked directly to DBD::ODBC without an ODBC >driver manager.

Yes, I did get unixODBC working, and Nick did apply a patch or two from me. I think that was a couple of years ago and I have not kept up-to-date with recent versions, so I'm not really sure where things stand now. Some of the things I worked on, like a dlopen() replacement, are probably not necessary now as the CRTL has steadily added that and a number of other things. The best place to keep up on what's been added when is in the version dependency tables in Appendix A of the CRTL reference: http://h71000.www7.hp.com/doc/82FINAL/5763/5763pro_072.html -- ________________________________________ Craig A.
