I've got a package for graph layout visualization, called Pigale,
which uses qt4 and GL via GLUT. It turns out the latter wants X11,
while I was able to get a qt4-mac port to build nicely. Pigale builds
fine under qt4-x11. Now I started poking around to see how those
things are configured, and my hunch is that I can use PKG_CONFIG_PATH
to have only one of
/opt/local/libexec/qt4-mac/lib/pkgconfig
/opt/local/libexec/qt4-x11/lib/pkgconfig
-- and everything will be done for the right Qt flavor, right? Pigale
uses --with-qt-includes=... switch to its configure, and giving it
either the Aqua's or X11's .../include/ worked to build the right
widgets. Apparently one can do things by QT4DIR, too -- so that would
be the right libexec subdir then?
What I am wondering about is the GL compatibility. Pigale uses
libfreeglut to label the graph, and that wanted X11. However, under /
opt/local/Frameworks/, it turns out, qt4-mac deposits a bunch of its
frameworks, including a QtOpenGL. Does anyone know how those
correspond to OpenGL, and why are the frameworks there only for qt4-
mac and not qt4-x11? Is it just a packaging choice to keep qt4-x11
linuxy-like and thus framework-less?
Cheers,
Alexy
