cmake 2.8.12 configure fails: in libnotify.dylib, file was built for unsupported file format which is not the architecture being linked

[spacecataz]

Greetings.

While updating outdated ports to macports 2.2.1, I have found that cmake fails on configure. I do not see recent similar tickets; the usual fixes do not help (i.e., cleaning the port, upgrading dependencies, etc.)

The error is below, the logfile is attached.

--->  Configuring cmake
Error: org.macports.configure for port cmake returned: configure failure: command execution failed

Hmm, the log says:

This is curious because I don't see why cmake would be trying to use libnotify. It's not listed as a dependency in the port, and I see no mention of libnotify in the compile line.

We've seen this once before, in #30697. That was also on Lion, also with llvm-gcc-4.2. There, the solution was to uninstall libnotify, which I recommend to you as well. Or if you actually need libnotify (or another port you've installed does), then the workaround would be to reinstall libnotify with the universal variant, i.e.:

sudo port upgrade --enforce-variants libnotify +universal

The fact that MacPorts chose to compile with llvm-gcc-4.2 instead of clang also suggests you are running Xcode 4.0 or 4.1; consider upgrading to Xcode 4.6.3.

Enforcing universal libnotify did work; this ticket should be closed. Thank you for your help. I will upgrade Xcode; however, my timeline for doing so is not immediate, so I will not be reporting on how this affects this issue.

Ok, closing, but I would probably consider upgrading to Xcode 4.6.3 the best solution.
