Thanks - patch applied to the stable branch. Would you mind taking some
time to port the patch to SVN TRUNK please? It's most likely that that
will go beta within a few weeks and unfortunately I'm *really* pushed
for time right now :-(

I can certainly try - what do you need to change? (BTW, build system
changes like this will only be applied to trunk - I consider support for
a new compiler to be a new feature, especially when we already have an
option for the target platform).

Ok. No problem. I will do it.

The problem what I have is that when I set CC and CXX environment
variable to Sun Studio compilers, configure generates Makefile which
contains wrong compiler switches (-Wall ...). I must manually change
makefile If I want to compile pgAdmin with Sun Studio. There is some
problem with openssl library detection on solaris as well.

OK, well I'll warn you up front that I'm not an automake/autoconf
*expert* so others on the list may have better ideas. I'm also going on
holiday for 2 weeks this weekend, so if I don't reply to you immediately
I'm not being rude :-)

At the moment most of the GCC flags are set in the Makefile.am files -
in particular we set

-Wall -Wno-non-virtual-dtor

I would look at moving that into the CLEANUP macro in acinclude.m4 (and
perhaps giving it a more suitable name), along with a conditional
alternative for the Sun compiler (if you check your config.log file,
hopefully you'll find a suitable variable to test for the compiler
name). I notice there are also a couple of other hacks at the end of
SETUP_WXWIDGETS (for Apple and Solaris) that could also move into that
macro.

I also notice that we setup CXXFLAGS and CFLAGS in the Makefile.am's
which we don't need at all - those lines can be removed from all the
Makefile.am's I guess.

When you've made changes to any of the Makefile.am's, acinclude.m4 or
configure.ac.in (in which you may need to update/add/remove and macro
names from acinclude.m4), just run the bootstrap script in $PGADMIN_SRC/
to regenerate everything, then run "./configure; make clean; make" to
test.
