CMake won't build on MacOS (i386 architecture is deprecated).

[hipcrime]

Since the most recent update, CMake refuses to build on MacOS. The failure generates tons of output, but the important bit is this:

:info:configure     ld: warning: The i386 architecture is deprecated for macOS (remove from the Xcode build setting: ARCHS)
:info:configure     ld: warning: ignoring file /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/lib/libSystem.tbd, missing required architecture i386 in file /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/lib/libSystem.tbd
:info:configure     ld: dynamic main executables must link with libSystem.dylib for architecture i386
:info:configure     clang: error: linker command failed with exit code 1 (use -v to see invocation)

Although it is in fact possible to get cmake to build +universal on Mojave, with some shenanigans:

$ /opt/universal/bin/port -v installed cmake
The following ports are currently installed:
  cmake @3.12.3_0+universal platform='darwin 18' archs='i386 x86_64' date='2018-11-05T23:25:47-0800'
  cmake @3.12.4_0+universal (active) platform='darwin 18' archs='i386 x86_64' date='2018-11-15T17:33:55-0800'

the real question is why would anyone want to? There is no useful purpose to having cmake +universal on Mojave, and it's been made quite difficult to do by Apple.

Please disable the +universal build and you should be good to go.

sudo port -v intall cmake -universal

should do it for you.

That worked ... thanks!

But now the same error is happening for these ports as well:

    gstreamer1-gst-plugins-base @1.14.4+ogg+universal+x11
    wine @3.0.3+universal+x11
    gtk2 @2.24.32+universal+x11

Is this something that's gone wrong with MacPorts on the latest versions of MacOS?

This error wasn't happening until the most recent MacPort upgrade.

Mojave does not support any universal builds, as MacPorts currently stands.

MojaveProblems#GeneralIssues

Wine is not available for Mojave 56991 until upstream works out a 64bit version.

Nothing's gone wrong with MacPorts. It's Apple's decision.

[hipcrime]

I am not running Mojave. I have High Sierra.

[kencu (Ken)]

Oh, I am very sorry then. This looked exactly like a mojave error, and there were no logs to look at more closely or information to steer otherwise. I apologize for jumping to that conclusion.

Do you have the Command Line Tools installed?

[ryandesign (Ryan Carsten Schmidt)]

Right. Install the command line tools or downgrade to Xcode 9.4.1. Either one will provide the 10.13 SDK with which you can build universal. Using only Xcode 10 on High Sierra without the command line tools will only get you the 10.14 SDK, with which you cannot build universal at this time.
