Harry-
You made reference to adding the -x11 tag to your variants.conf.
By doing this, do you force macports to use Apple's X11? Or is it something else entirely different?

thanks

Thanks for the reply Harry-
I'm fairly sure that I will need to lipo together the builds for Musicbrainz' Picard. So - in your experience what are all the options that I must set after a fresh src install to have a 10.5 setup building binaries for 10.4?


Nothing more than setting the right options in your macports.conf and then see how far you get.

Don't forget to use Reply All so the discussion goes to the list as
well. There are no guarantees that this will work, but the way to do
what you want would be to set universal_target to 10.4,
universal_sysroot to /Developer/SDKs/MacOSX10.4u.sdk, and
universal_archs to i386. Then build everything with +universal (best to
add it to your variants.conf).

Also set x11prefix to /usr/X11R6; Leopard's X11 prefix /usr/X11 does not exist on Tiger.


If I do this, how will I be able to run the executables on my 10.5 setup?



I ran into the same issue and simply decided to make links.

On Tiger I simply did "sudo ln -s /usr/X11R6 /usr/X11". If you build on Tiger and bring them to Leopard you do
"sudo ln -s /usr/X11 /usr/X11R6".

This works only on your own system off course, unless you make an installer that checks whether it runs on Tiger or Leopard and creates a softlink accordingly.
