      I am basically copying a forum post I made about this issue:


      I'm porting my code to Qt 5.11 and I now get this message when I build my project:

      cd momagse/ && ( test -e Makefile || /usr/local/Cellar/qt/5.11.2/bin/qmake -o Makefile /Users/brad/labcode/qt56_port/momagse/momagse.pro -config release ) && /Applications/Xcode.app/Contents/Developer/usr/bin/make -f Makefile


      xcrun: error: no utility name specified
       Usage: xcrun [options] <tool name> ... arguments ...
      Find and execute the named command line tool from the active developer
      The active developer directory can be set using xcode-select, or via the
       DEVELOPER_DIR environment variable. See the xcrun and xcode-select manual
       pages for more information.
       -h, --help show this help message and exit

      After some more digging, I've found some things:

      1. This only happens for apps and not libs
      2. I build my projects in debug_and_release mode, so it generates 3 Makefiles: Makefile, Makefile.Debug, Makefile.Release
      3. I noticed that this only occurs when I do "make" instead of explicitly stating the debug or release versions (make -f Makefule.Debug), so this led me to believe there was something unique about "Makefile".
      4. So I went and poked around a bit and noticed this line:
      include /usr/local/Cellar/qt/5.11.2/mkspecs/features/mac/sdk.mk

      I navigated to that file and found this line in that file:

      CURRENT_MAC_SDK_VERSION := $(shell /usr/bin/xcrun --sdk $(EXPORT_QMAKE_MAC_SDK) -show-sdk-version)

      I was able to reproduce the output in the original post with the following command:

       /usr/bin/xcrun --sdk -show-sdk-version

      If I do what it's supposed to do:

      /usr/bin/xcrun --sdk macosx -show-sdk-version

      Then it produces the expected output of:


      So that would suggest $(EXPORT_QMAKE_MAC_SDK) was undefined, so I went back into the qmake generated Makefile and noticed this:

      MAKEFILE = Makefile
      first: release
      install: release-install
      uninstall: release-uninstall
      include /usr/local/Cellar/qt/5.11.2/mkspecs/features/mac/sdk.mk
      QMAKE = /usr/local/bin/qmake511
      DEL_FILE = rm -f
      CHK_DIR_EXISTS= test -d
      MKDIR = mkdir -p
      COPY = cp -f
      COPY_FILE = cp -f
      COPY_DIR = cp -f -R
      INSTALL_FILE = install -m 644 -p
      INSTALL_PROGRAM = install -m 755 -p
      INSTALL_DIR = cp -f -R
      QINSTALL = /usr/local/bin/qmake511 -install qinstall
      QINSTALL_PROGRAM = /usr/local/bin/qmake511 -install qinstall -exe
      DEL_FILE = rm -f
      SYMLINK = ln -f -s
      DEL_DIR = rmdir
      MOVE = mv -f
      TAR = tar -cf
      COMPRESS = gzip -9f
      DISTNAME = momadataview1.0.0
      DISTDIR = /Users/brad/labcode/qt5/momadataview/build/release/obj/momadataview1.0.0
      SUBTARGETS = \
      release \
      ####### Custom Variables
      EXPORT_QMAKE_MAC_SDK = macosx

      Notice how the "Include" line comes before the definition of "EXPORT_QMAKE_MAC_SDK" and "EXPORT_QMAKE_MAC_SDK_VERSION" at the bottom.

      So, it looks like this is why this is happening. To test my hypothesis, I went and moved the two variables above the include and reran "make". Lo and behold, this was my output:

      /Library/Developer/CommandLineTools/usr/bin/make -f Makefile.Release
       make[1]: Nothing to be done for `first'.
