xcrun: error: no utility name specified

SGaist

Hi,

Do you know the exact line of the Makefile that triggers that ?

btse

After some more debugging, I was able to fix this by updating my XCode version to 9.1, MacOS SDK 10.13 and also updating my OS from Yosemite to High Sierra.

I don't know which of these fixed the problem, but I'm not getting that output anymore.

Scratch that, I didn't actually resolve this.

SGaist

Then, my question still is valid.

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

This only happens for apps and not libs
I build my projects in debug_and_release mode, so it generates 3 Makefiles: Makefile, Makefile.Debug, Makefile.Release
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".
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:

10.13

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 \
		debug


####### Custom Variables
EXPORT_QMAKE_MAC_SDK = macosx
EXPORT_QMAKE_MAC_SDK_VERSION = 10.13
...

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'.

I suppose this is a bug then? I'm surprised this was not caught during testing, it seems like a pretty normal work flow.

It's possible there's something wrong with my Qt version or I'm doing something wrong in my project files.

SGaist

Interesting results !

Can you reproduce that with a minimal .pro file ?

btse

Yup, so I created a new QWidget project with Qt Creator.

I manually added "CONFIG += debug_and_release" to the .proj file and I was able to reproduce the initial problem.

Seems like "debug_and_release" mode really got screwed around in Qt5+. I actually have another bug ticket already open because "debug_and_release" auto generates "debug" and "release" dirs when I don't want it to (even with "debug_and_release_target" removed), which it never did in Qt4's qmake.

SGaist

Can post the link to the ticket ?

Can you test with Qt 5.12's beta ?

Hi,
any news about this?
I just upgrded to Qt 5.11.2 and McOS 10.14.1.
Now i get the same problem.

xcrun: error: no utility name specified
Usage: xcrun [options] <tool name> ... arguments ...

Find and execute the named command line tool from the active developer
directory.

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.

Options:
  -h, --help                  show this help message and exit
  --version                   show the xcrun version
  -v, --verbose               show verbose logging output
  --sdk <sdk name>            find the tool for the given SDK name
  --toolchain <name>          find the tool for the given toolchain
  -l, --log                   show commands to be executed (with --run)
  -f, --find                  only find and print the tool path
  -r, --run                   find and execute the tool (the default behavior)
  -n, --no-cache              do not use the lookup cache
  -k, --kill-cache            invalidate all existing cache entries
  --show-sdk-path             show selected SDK install path
  --show-sdk-version          show selected SDK version
  --show-sdk-build-version    show selected SDK build version
  --show-sdk-platform-path    show selected SDK platform path
  --show-sdk-platform-version show selected SDK platform version

No, it's annoying but I've been ignoring it since it doesn't actually break anything.

Here's the bug ticket I just created about it: https://bugreports.qt.io/browse/QTBUG-72449

I have not tested to see if this was resolved with Qt 5.12. I'll try that sometime soon.

I created a new QWidget assignment with Qt author.

I manually delivered "CONFIG += debug_and_release" to the .proj file and i used to be capable of reproduce the preliminary trouble.

looks as if "debug_and_release" mode certainly got screwed around in Qt5+. I simply have every other trojan horse price tag already open because "debug_and_release" automobile generates "debug" and "release" dirs after I don't want it to (despite "debug_and_release_target" eliminated), which it in no way did in Qt4's qmake.

btse

@fouad1995 Yup, I actually created a bug about this one also: https://bugreports.qt.io/browse/QTBUG-71437

Seems like it's too low priority for them to actually do anything about it. I haven't tried to see if this was somehow resolved in 5.12 yet, but I find it unlikely.
