I don't have access to a Solaris machine, so I can't do anything to help these users.
The patch in 117606 looks right to me: gcc on Solaris (and on any other platform) needs -shared to build shared library; configure currently passes -G. I haven't actually tried the patch, since it is a pain to extract it from the SF bug report page. What happens is that gcc passes -G to the linker, which correctly produces a shared library. However, gcc also links crt1/crti into the library, which causes the reference to main. 117508 looks like a user error to me. On its own, configure would not try to link -ldb, unless it detects the presence of db.h. My guess is that there is a libdb in /usr/local, so a gcc configure finds it, whereas the native compiler doesn't. Later, the linker even finds a -ldb library, but somehow this doesn't have dbopen. So it could be that the BSDDB installation on that system is screwed. Regards, Martin
