Bugzilla Bug 79620

I have xorg-x11 6.8.0-r4 installed.  I am on a fresh 2004.3 install from
stage1, stable arch (x86).  dev-db/unixODBC can't seem to find the X11 libs.  

My guess is chicken-and-egg problem.  qt wouldn't build with 'odbc' use flag
unless you had odbc installed.  odbc wouldn't build with 'qt' use flag unless
you had qt installed.  I'm sure there is a problem, but i'm not 100% on what
causes it or how to fix it yet.

after emerge'ing qt, unixODBC script continues to fail at finding X libraries
when USE="qt gnome".   Not chicken-and-egg problem.

i'm referencing my /etc/portage/package.use:

# does not work
=dev-db/unixODBC-2.2.6 -gnome qt

# works fine
#=dev-db/unixODBC-2.2.6 gnome -qt


This is a problem when the 'qt' USE flag and unixODBC-2.2.6

I experienced the same problem.  I had to USE="-odbc" emerge qt to get QT
installed, but attempting to install unixODBC afterward gave me that same error
regarding X libraries not being found.

The problem regarding the QT and ODBC flags together seems to just be the QT
libraries attempting to use the database drivers before they've been installed,
and the unixODBC drivers requiring QT be installed before they'll go in.

When I attempted to emerge just qt, it would list unixODBC then qt.  When I
attmempt to emerge just unixODBC, it would list qt first.  That is probably
where you got the chicken and egg theory from.

Since X.Org the libraries path has been moved to another loacation. You have to
edit current unixODBC ebuild and add --x-libraries flag to configure script in
src_compile() function.
This works fine for me:

src_compile() {
        local myconf

        if use qt
        then
                myconf="--enable-gui=yes"
        else
                myconf="--enable-gui=no"
        fi

        ./configure --host=${CHOST} \
                    --prefix=/usr \
                    --sysconfdir=/etc/unixODBC \

                    ${myconf} || die

        make || die

        if use gnome
        then
                # Symlink for configure
                ln -s ${S}/odbcinst/.libs ./lib
                # Symlink for libtool
                ln -s ${S}/odbcinst/.libs ./lib/.libs
                cd gODBCConfig
                ./configure --host=${CHOST} \
                                --with-odbc=${S} \
                                --prefix=/usr \
                                --sysconfdir=/etc/unixODBC \
                                || die

                # not sure why these symlinks are needed. busted configure, i
guess...
                ln -s ../depcomp .
                ln -s ../libtool .
                make || die
                cd ..
        fi
}

!!!And sorry for my bad english

Committed.
