gperf: Cannot be installed +universal on Mojave

[nhojpatrick (John Patrick)]

Just upgraded to Mojave, reinstalled Ports and followed wiki:Migration, also looked at ticket:57245 which additionally talks about doing xcode-select --install and xcodebuild -license which I've done.

I've also got Terminal set to /opt/local/bin/bash -l and when i relaunch I get this;

[Command not found: /opt/local/bin/bash]

[Could not create a new process and open a pseudo-tty.]

This is the error I see;

--->  Computing dependencies for bash-completion
--->  Dependencies to be installed: bash gettext libiconv gperf ncurses
Error: gperf cannot be installed for the configured universal_archs 'x86_64 i386' because it only supports the arch(s) ''.

Are you requesting the +universal variant? You should not do that on Mojave, as it can no longer build 32-bit binaries.

Did you already migrate your /opt/local/etc/macports/macports.conf (compare to macports.conf.default right next to it)? I would recommend to remove i386 from the universal_archs option.

The error is unrelated to bash-completion, just one of the dependencies threw an error. Reassigning to gperf.

[jmroot (Joshua Root)]

Same as #57245; the macOS 10.14 SDK doesn't support universal or i386 builds.

[nhojpatrick (John Patrick)]

I executed "sudo port install bash-completion", so does that mean the port needs to change?

$ sudo port install bash-completion
--->  Computing dependencies for bash-completion
The following dependencies will be installed: 
 bash
 gettext
 gperf
 libiconv
 ncurses
Continue? [Y/n]: y

My config is also the default config e.g.

$ diff /opt/local/etc/macports/macports.conf.default /opt/local/etc/macports/macports.conf
$

[nhojpatrick (John Patrick)]

/opt/local/etc/macports/macports.conf

[nhojpatrick (John Patrick)]

Had to do a complete uninstall of mac ports, then reboot, install mac ports Mojave, then sudo port install bash-completion and it works.

Been upgrading mac ports since macOS Mavericks, have not touched macports.conf apart from as a result of raising a trac ticket and being told to change a setting to get a port install/upgrade working.

The port doesn't need any changes. You just can't install ports universal on Mojave, so don't try to do so. Don't specify +universal on the command line, or in variants.conf, or in myports.txt as part of migration.
