Hi all, hi Konqi, hi Tux,


I need help linking an app with linpq++ from PostgreSQL.

When I link my app with libpq++ I get the following:

/bin/sh ../../libtool --silent --mode=link g++  -O2  -g
-L/home/devel/local/kde/lib -L/home/devel-qt/qt/lib  -L/usr/X11R6/lib
-L/usr/local/lib -rpath /home/devel/local/kde/lib -rpath /home/devel-qt/qt/lib
-rpath /usr/X11R6/lib -lpq++ -o ktables  tableselectdata.o tableselect.o
ktablesserver.o ktablesview.o ktablesdoc.o ktables.o main.o
../../lib/kofficeui/libkofficeui.la ../kdb/libkdb.la

../kdb/.libs/libkdb.so: undefined reference to `PgConnection type_info function'
../kdb/.libs/libkdb.so: undefined reference to `PgConnection type_info node'

make: *** [ktables] Error 1 

When I link without libpq++:

/bin/sh ../../libtool --silent --mode=link g++  -O2  -g
-L/home/devel/local/kde/lib -L/home/devel-qt/qt/lib  -L/usr/X11R6/lib

I have to link my app with libpq++. It looks like missing moc-files when linking
with libpq++ but PostgreSQL donīt know QT, I think. What does I make wrong ?
