Thread: Constant changes (Re-Build)

Hi I'm a student from Valencia-Venezuela and I'm working with some<br /> other friends to make PostgreSQL allows the
definitionof Temporal <br /> Databases and their respective Selection, Insertion and some other<br /> functions needed
totreat this paradigm  (all based in TSQL2 Query <br /> Language). <br /><br /> Right now we are working directly on
thesource code and making <br /> different changes during the day, so I'd like to ask you which is the better<br />
choicefor re-building (I'm not sure if that is the right term) only the code<br /> files that I just have changed.<br

You don't need to configure each time.  Just do a "make ; make install",
and that will only compile the files you changed.  Be sure to use
the --enable-depend option to configure the first time, though.

You'd only need to mess with "configure" if you added directories, or
you changed configure input files (e.g. pg_config.h, configure.in, etc).

That's interesting. May I suggest that you take a look at a book called 
"Temporal Data & the Relational Model" by C.J. Date, Hugh Darwin and 
Nikos Lorentzos 
(http://www.amazon.com/Temporal-Relational-Kaufmann-Management-Systems/dp/1558608559). 
It describes the best approach I've seen this far to dealing with 
temporal data.

Well, you don't need to run configure every time you want to build. If 
you just run "make", it will compile just the changes. I'd suggest 
running the configure with the --enable-depend option, so it picks up 
changes in header files better.

Also take a look at ccache (http://ccache.samba.org/). And if you have 
more PCs to spare, you might want to set up distcc.
