unison +aqua build fails (port may be hard-coded to expect 10.5 SDK?)

[jwhowse4]

On an Intel mac running Leopard 10.5.8 and Xcode 3.1.4, my unison build with the +aqua flag fails with the following error. Any idea what is wrong?

This patch worked for me (I'm not sure if this is how I should submit this, let me know if you need a different format):

The SDKROOT lines should be set to ${configure.sdkroot}, or deleted entirely if that variable is empty.

[ryandesign (Ryan Carsten Schmidt)]

The problem remains in modified form: the current version of unison +aqua is looking for the 10.5 SDK, which doesn't exist by default on a Lion install of Xcode. See #32297.

A patch for this was submitted by larryv in #40052.

I still run into the same bug (in the form reported in #40052) under Mavericks. Will try larryv's patch...

[mf2k (Frank Schima)]

This port is no longer maintained. See #44276.

[hmeine (Hans Meine)]

I wonder if this should be closed in faver of #40052, just because the latter is much more complete and useful.

In any case, I applied the patch, too, using

curl 'https://trac.macports.org/raw-attachment/ticket/40052/remove-sdk.patch' | sudo patch -d $(port dir unison) -p0

and while it solves the problem of the missing SDK, unison does not build due to some genuine build errors, obviously the same as in ​https://trac.macports.org/attachment/ticket/40052/main.2.log

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

I believe this issue was fixed in ​in a recent update.
If not, the +aqua variant ​no longer exists on older system.
