Hmmm....seem to be getting a weird linker error when I build OGL (from the independent package) against 2.9: /usr/bin/ld: ogl_dll_composit.o: relocation R_X86_64_32 against `wxDivisionControlPoint::ms_classInfo' can not be used when making a shared object; recompile with -fPIC ogl_dll_composit.o: could not read symbols: Bad value collect2: ld returned 1 exit status I take it that you didn't see this Dave? I built it against 2.9, which was itself built using a shell script that's the same as ./xtra/build-wxgtk, except that I removed the contrib stuff. Should -fPIC be in our CXXFLAGS? If so, why wouldn't it be? > Yeah - I imagine the code had a few contributors over the years.

I'll ask the question so. > I imagine that makes for a big (and ugly) patch - the main reason we > use c_str() is so we can pass wxStrings to variadics. Maybe we should consider using an alternative to conventional variadic functions. There are lots of things to not like about them. Boost.format is a good alternative . It may not actually be worth pursuing, but it's worth noting. >> This code in ctlSQLBox::RegexFindText() errors: >> >> wxWX2MBbuf buf = (wxWX2MBbuf)wx2stc(text); >> >> wx2stc is now in private.h .

Find attached latest error output. All miscellaneous issues have been resolved. I'm only missing these object files now: g++: pgAdmin3.o: No such file or directory g++: ctlSQLBox.o: No such file or directory g++: explainCanvas.o: No such file or directory g++: explainShape.o: No such file or directory g++: frmQuery.o: No such file or directory g++: parser.tab.o: No such file or directory I believe that the only things standing between us and a rough 2.9 build are: 1. The linker problem above. OGL compiles acceptably. 2. The problem with pgsParser.yy. This is probably exceedingly simple, but I haven't managed to fix it yet. 3. The problem with wx2stc() above. I could have fixed this by copying and pasting the tiny function which only appears in private.h in 2.9, but it that would violate the wxWindows licence. I have had to do one or two things that I'm not overjoyed with to get to this point, including using a const_cast to cast away constness from a handle (wxChar*) to the internal buffer used by wxString. -- Regards, Peter Geoghegan
