    Exclamation Error compiling psql plugin

    System: debian etch.
    PostgreSQL client installed is 8.1.9 from synaptic

    I downloaded the PostgreSQL 8.2.5 source and tried to compile the plugin but it won't compile.
    Is it because the versions are different ?

    Do you have libpq-fe.h header somewhere on your system? Maybe you have to install some additional package like postgresql-devel?

    yes: /usr/include/postgresql/libpq-fe.h
    libpq-dev is installed, I also tried to compile with
    make -I /usr/include/postgresql/

    You have to pass the include path to qmake already. Can you show us the qmake line you tried using to compile the postgres plugin?

    OK, I see where I went wrong,
    qmake -o Makefile "INCLUDEPATH+=/usr/include/pgsql" "LIBS+=-L/usr/lib -lpq" psql.pro
    My INCLUDEPATH was invalid.
    Thanks,
