macOS: CommandLineTools and mkspec mismatch

  • Moderators

    Hi everyone,

    I recently setup a new MacOS dev environment, the previous hardware was not compatible with the newest OS, and I've run in a so far unencountered issue.

    I installed X-Code and Homebrew and during both installations Developer CommandLineTools where installed. And they are now duplicated on my System.

    As a result, the autodetection of the ios-Kit did not work. So I added it manually.
    QtCreator now tells me that qmake uses a different toolset than selected in the kits.

    in principle this shouldn't be an issue, and for desktop compilations it actually isn't, but when set to iOS I get the error "Could not recolve SDK Path for iPhones using --show-sdk-path"

    I would like to set the default toolset to the one installed by X-Code and as a result let the Auto-Kit detection do its magic. This should solve the warnings and the sdk-path issue as well.

    But I'm unsure how and where to do this.

    Removing Homebrew solved the issue.

    My problem is gone, but if anyone has answer to the above question, I would like to hear/read it.

    Any chance that the homebrew Qt qmake was in your PATH ?

    @SGaist hi,

    Chances are that Homebrew installation did make changes to the path. It does requier a sudo call to install correctly.

    Also after removing Homebrew, everything wan't fixed from the get go, I had to call sudo /usr/bin/xcode-select -switch /Applications/Xcode.app/Contents/Developer to fix compiler link errors.
