font-family:Arial">Okay, now that I have some time to concentrate on getting programs using the libpq and/or libpq++ to
compileI will try this message again. I am using PostgreSQL 7.1.3, glibc-2.2.4-19.3 and gcc-2.96-85. Any time I try to
compilea program that uses the libpq or the libpq++ headers or libraries i get errors. When I installed PostgreSQL i
usedboth make install, and make install-all-headers to ensure that all the header files were copied to the system and I
didboth the commands as root. I have included some of the output I get when I try compiling different
ways.</span></font><pclass="MsoNormal"><font face="Arial" size="2"><span style="font-size:10.0pt;

notput the libpq++ headers into the pgsql/include. If anyone has any reasons why this might be I would be more than
happyto learn.</span></font><p class="MsoNormal"><font face="Arial" size="2"><span style="font-size:10.0pt;
