Install from scratch new empty project won't compile

Hi,

just installed 5.11.2 on a mac.

I'm creating a new empty qml project and am immediately greeted by

"Project WARNING: Qt requires at least version 10.12 of the platform SDK, you're using 10.11. Please upgrade"

beginning of system information:

{noformat}
Qt 5.11.2 (x86_64-little_endian-lp64 shared (dynamic) release build; by Clang 8.1.0 (clang-802.0.42) (Apple)) on "cocoa" 
OS: macOS 10.14 [darwin version 18.0.0]

i think XCode is up to date because i can't update it in the app store. ( Version 10.0 (10A255) )

uninstalled qt using the maintenance tool, reinstalled it, created a new project.. same result..

what am i missing here ?

kind regards,
tom

Do you mean app store does not provide any updates for XCode?
The warning clearly says what the problem is, reinstalling Qt will not help.

@clogwog said in Install from scratch new empty project won't compile:

10.14 is Mojave, I'm surpised xcode installed such an old SDK version. The newest should be 10.14 (correlating with the OS version)

you should be able to find and download the sdk here, if xcode fails to download it automatically.

clogwog

is the Platform SDK the android platform SDK ? Because i don't think that is what apple is calling their SDK..

I can only see the
"Kernel Debug Kit 10.14"
or the
"command line tools 10.14 for XCode 10"
in the https://developer.apple.com/download/more/ downoad link

Just re-installed XCode just in case that was the problem, but it didn't help.. still complaining about the Platform SDK.

if i ignore the warning and try to build the exact output is:

see the "platform has been changed, please clean and delete..." ?
this is a brand new project, this is the first time this is being build.

Hi,

What do you get if you run xcodebuild -showsdks ?

clogwog

Which one of these SDK's is referred to when the error mentions "Platform SDK" ?

SGaist

Since you are building for macOS, it's macosx10.14.

I would do a search on your machine in order to find if there's any .qmake.* file lying around containing 10.11

clogwog

@SGaist said in Install from scratch new empty project won't compile:

.qmake.*

found all items of .qmake.* and removed them.
still same error.

just figured out if i change to use qbs instead of qmake it works..
searched for all instances of qmake :

/Users/clogwog/Qt/5.11.2/ios/bin/qmake
/Users/clogwog/Qt/5.11.2/android_armv7/bin/qmake
/Users/clogwog/Qt/5.11.2/android_x86/bin/qmake

/Users/clogwog/Qt/5.11.2/Src/qtbase/qmake
/Users/clogwog/Qt/5.11.2/Src/qtbase/examples/qmake

and /Users/clogwog/Qt was empty before the install using the online installer.

i guess i can continue just using qbs

just wish i knew what is going on here.

SGaist

Did you try to search for any file containing 10.11 ?

clogwog

@SGaist yes, can't find any Qt related file that still points to 10.11

Jartza

I seem to suffer from same problem, except the error shows different version. Tried following:

shenanigans:qml_tagsutest jartza$ qmake
Project WARNING: Qt requires at least version 10.14 of the platform SDK, you're using 10.13. Please upgrade.

but:

shenanigans:qml_tagsutest jartza$ xcrun --show-sdk-path
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk

and

shenanigans:qml_tagsutest jartza$ xcodebuild -showsdks

@Jartza i know it's not a fix, but if you switch to the QBS build system instead of qmake it seems to work.

Hi... I'm facing the same problem and well... here is what I get looking for 10.11 on "qmake" files:

~/Qt/5.11.2/clang_64/mkspecs/macx-clang/qmake.conf (1)
5 QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.11
~/Qt/5.11.2/clang_64/mkspecs/macx-g++/qmake.conf (1)
13 QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.11
~/Qt/5.11.2/clang_64/mkspecs/macx-icc/qmake.conf (1)
101 QMAKE_MACOSX_DEPLOYMENT_TARGET = 10.11

But even if I change this values to 10.14, the error persists

jamesalexander

I'd like to indicate that I have the sam issue. I ran into the problem because I had an older version of XCode, I upgraded, but the problem persists, i.e. qmake is referring to my using 9.3 of iOS simulators, when I have 10.x installed. Creator build config validates the various versions of iOS simulators I have are in fact new.
