This mkspec requires Xcode 4.3 or later

@SGaist said in This mkspec requires Xcode 4.3 or later:

message("Test: $$QMAKE_XCODE_VERSION")

I put that at the top of my .pro file but I don't see the result anywhere in any of the console windows when I run qmake or build.

I'm thinking of re-installing Qt from scratch... this is exhausting...

SGaist

That's strange... You should at least get "Test:" printed.

Did you try with a more recent version of 5.9 ? IIRC the current is 5.9.6.

kgregory

When I run it with Qt 5.11.1 as the target, I get "9.4.1".

kgregory

It says the error occurs while parsing my .pro file. I don't know if that means anything to you, but I assume that if it fails to parse, then it's not going to print the message.

SGaist

What if you put it in an empty pro file ?

kgregory

When I created a new project and compile for Qt 5.11.1, it returns 10.0. When I compile for 5.9.3, I get the Xcode 4.3 error.

kgregory

Well, I re-installed Qt from scratch and nothing changed. :-(

I'm using Qt 5.11.2 now instead of 5.11.1, though.

kgregory

Ok, I installed 5.10.2 and am able to compile and deploy with that. Furthermore, it solves my problem. Apparently, whatever bug I encountered was introduced between then and 5.11.1.

Here is the thread for the bug I was dealing with: https://forum.qt.io/topic/95085/qlowenergyservice-never-completes-discovery/2

SGaist

Did you check whether the bug report system has something related ?

After you did the copy of the mkspecs, you need to make sure you remove any .qmake.stash files that it has in the directory or parent directories as it may be reusing those. Other than that, upgrading Qt 5.9.x might help too, otherwise you have to trawl the fixes to see what changed it though using the mkspecs/features directory should have helped.

This is a documented bug https://bugreports.qt.io/browse/QTBUG-70592 and the fix is in 5.9.7 due out next week. There is no workaround, as far as I am aware.

The workaround is to disable the check for xcode versions in mkspecs files, to do this prepend false: before lessThan(QMAKE_XCODE_VERSION in those files :

mkspecs/features/uikit/default_pre.prf:24
mkspecs/features/uikit/default_post.prf:42
mkspecs/features/uikit/bitcode.prf:1

For default_pre.prf, line 24 should then be:
false:lessThan(QMAKE_XCODE_VERSION, "4.3"): \
