[Libpqxx-general] LD_FLAGS used when checking for libpq

[Jorgen Austvik - Sun Norway]

Hi,

I have had some problems building libpqxx:

--------8<--------------8<--------------8<--------------8<--------------8<------
checking for main in -lpq... no
configure: error:
Could not link to libpq.  Make sure you have the PostgreSQL client library
installed, and that the library binary can be found in the location 
returned by
"pg_config --libdir".
--------8<--------------8<--------------8<--------------8<--------------8<------

config.log:
--------8<--------------8<--------------8<--------------8<--------------8<------
configure:21266: /opt/studio11/SUNWspro/bin/cc -o conftest -xO3 
conftest.c -lpq 
-L/usr/local/postgres/version/NIGHT/SunOS_i386/usr/postgres/8.3/lib  >&5
"conftest.c", line 37: warning: statement not reached
ld: fatal: library -lpq: not found
ld: fatal: File processing errors. No output written to conftest
--------8<--------------8<--------------8<--------------8<--------------8<------

The problem is that the -lpq switch is before the -L switch on the 
command line.

With changes like the attached patch, the linker is told where to to 
find libpg before the -lpq switch, and compilation works for me.
