The platform SDK error

[kshahim]

after updating Mac to the newest MacOS Catalina 10.15.4, in building i receive this error :

The platform SDK has been changed from version 10.15 to version 10.15.4.
This requires a fresh build. Please wipe the build directory completely,
including any .qmake.stash and .qmake.cache files generated by qmake.

I tried removing the build dir, and also changing the line in qdevice.pri
QMAKE_MAC_SDK = macosx10.15.4

but not yet successful in building the desktop application.

@kshahim So, what happens if you delete build directory, run qmake and build?

[kshahim]

when i change the line in qdevice.pri to :
QMAKE_MAC_SDK = macosx10.15.4

i receive this error :
"Project ERROR: Could not resolve SDK Path for 'macosx10.15.4' using --show-sdk-path"

If i have the line set to :
QMAKE_MAC_SDK = macosx10.15

the error message :

"The platform SDK has been changed from version 10.15 to version 10.15.4.
This requires a fresh build. Please wipe the build directory completely,
including any .qmake.stash and .qmake.cache files generated by qmake"

I removed the build dir, but still i did not succeed in building.

here is the output of following command :
xcrun -sdk macosx --show-sdk-path

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk

Hi,

IIRC one thing you can do is create a symbolic link in the same folder.

@SGaist said in The platform SDK error:

IIRC

So I made a symbolic link folder for 10.15.4 as following:

the result of following command is:
xcrun --sdk macosx --show-sdk-path
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.4.sdk

then, i changed the line in qdevice.pri, to 10.15.4

however, after fresh building, I receive this error in qt:
error: Could not resolve SDK Path for 'macosx10.15.4' using --show-sdk-path

[SGaist]

Casing is important.

@kshahim said in The platform SDK error:

MacOSX1

the one in qdevice.pri is : QMAKE_MAC_SDK = macosx10.15.4
and the symbolic folder is MacOSX10.15.4.sdk

i changed the one in qdevice to QMAKE_MAC_SDK = MacOSX10.15.4

still the same error:
Project ERROR: Could not resolve SDK Path for 'MacOSX10.15.4' using --show-sdk-path

I had the same bizarre error. Fixed it by removing build folders from .gitignore.

@ostoimenov Thank You!! this solved my issue :)

These files were invisible in Mac :

Then i pressed :

to make them visible and i removed the stash files, and it is working now !

Hello,
I know this topic is old, but just wanted to ask where are located this .gitignore and .qmake_stash files that need to be removed. I have the same problem on macOS Catalina with all newer Qt versions 5.12, 5.13, 5.14, 5.15. Thanks.

Ok I just found current workaround, Comment everything in the file:

/Your Qt Directory/ mkspecs / features/mac / sdk.mk
