Updated Qt Creator today to version 4.11.2

@SPlatten what happens when you create a new fresh hello world project?

SPlatten

Just create a new project and lots of new issues, before I even got to compile:

@SPlatten
well, maybe someone else can help,

For me, deleting the bild directory always fixed the platform SDK has been changed issues for me.

That said, just to make sure, you did update Xcode after the MacOs update ?
And 5.11 is really old. I would at least suggest 5.12, that one gets as an LTS version potential bugfixes

SPlatten

I'm now at the stage where I've completely uninstalled everything, now about to try download and install again.

SPlatten

After a long wait to install the new version, I get exactly the same message, omg!!!

Any suggestions ?

SPlatten

This is what I've tried now:

Delete build folder completely.
Delete XMLMPAM.pro.user.
Launch Qt Creator.
Go to Projects.
Check only Desktop Qt 5.14.2 clang 64bit.
Click on the Configure Project button.
When back to Projects, right clicked on Build directory and selected Create Folder.
From the Build menu selected Run qmake.

In the Issues tap up pops:

    No rule to make target `XMLMPAM'. Stop.

Can someone please help?

Found it...after a search on google I found someone else who had the same problem and all I can say it that it must have been caused as a result of a change to the build and "pro" make file system. Until today my files and build have worked.

All I had to do was have a file of the same name as the project, so I renamed main.cpp to XMLMPAM.cpp and it built fine and no more error message.

mmm....Maybe I spoke to soon, whilst having a source file of the same name as the "pro" file gets rid of the message, the project won't build:

Xcode version is 11.4 (11E146)

After another google found this and executed in terminal:

    sudo find / -name '.qmake.*' -delete

A lot of found files could not be deleted but at the end of it, I tried building again and it worked.

@SPlatten
Great you managed to solve the issue and thanks for sharing the answer!

So it was a qmake.cache issue, but your compiler somehow picktup those files outside the normal search directory 🤔 Do you happen to use a versioning system? IIRC there was an issue with git ignore and qmake.cache 🤷‍♂️

SPlatten

I use git.

I have run into this 3 times before. As far as I know it's within Qt. When Mac OS/Xcode update, there are some targets within Qt itself that "break" because they point to specific versions of something on the Mac side. Each time it has happened I've had to wait for a new minor version at least of Qt for it to resolve.
https://doc.qt.io/qt-5/macos.html
They must be using Mac OS or Xcode minor versions within Qt. WHY they still do this I do not understand! Why not just go Major versions? If Xcode goes from 11.3 to 11.4 or Mac OS from 10.15.3 to 10.15.4 (I got both those updates recently so I don't know which, but last time it was Xcode) why should I have to wait to compile our app? That seems like a huge deal to me.
So last time this happened, the community just told me don't allow Xcode to upgrade or keep an old copy around. I guess they don't understand the current world of Apple where they basically force everything on us.
Did you find a way around it? I tried 15.4.2 and still go the error so likely now I have to wait for 15.14.3.

There are complete instructions for downloading, finding and installing older SDKs in newer XCode versions in this answer on Stack Overflow:
