[Dbbalancer-users] Re: DBBalancer

[Daniel V. S. <dv...@ar...>]

Hello Frank.

Postgres libraries are not mandatory to build DBBalancer, since DBBalancer 
uses the Postgres protocol at a low level (with the danger of being outdated 
by protocol changes, of course...), and handles it by itself. This is so 
because only a very small part of the protocol needs to be used, actually 
opening and closing of the connections, only.

So, what is stopping "configure" is the lack of libACE, not the lack of libpq 
or libpq++, which will only prevent the building of a couple of test 
programs. Anyway, a "--with-pq=/usr/local/pgsql" should help with the libpq 
error....

I would like to hear about the outcome of any study or test you do with 
DBBalancer, since I could use that to improve it.

Regards
Daniel.

PS: Yes, compiling ACE takes a LOOOOOONG time, specially with gcc3. But it is 
a very nice C++ library and it helped a lot in the development of 
DBBalancer... Maybe you can be a binary. I think that there are ".deb"s and 
maybe you can extract the binaries from there, even for your RedHat (tip: use 
"ar x ...")
