Updated Qt Creator today to version 4.11.2

SPlatten

I haven't changed anything in the project that I was building in the previous version, now in the Compiler Output:

I haven't seen this before and in the Issues:

    :-1: error: No rule to make target `XMLMPAM'.  Stop.

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.

J.Hilk

@SPlatten delete your shadow build folder, really delete it cleanwill not be enough, and build it from scratch.

SPlatten

What exactly is the Shadow build folder? I've just emptied the build folder and executed QMake I get the same message.

J.Hilk

@SPlatten
you find the absolute path in the build settings of QtCreator

SPlatten

Yes, that contains the location of all the object files and executable that I just removed, it was an empty folder. Then executing QMake resulted in the same error, didn't get as far as building.

As an additional step, I exited Qt Creator, make sure the folder was empty, then relaunched Qt Creator.

Still the same message.

J.Hilk

@SPlatten
including any .qmake.stash and .qmake.cache files ?

as an additional move, you can try:
Closing QtCreator

delete the *.pro.user file
-Open the project anew

This should force a new project setup and could help.

SPlatten

This time I deleted the folder, then re-created it, same message after running QMake.

Then I closed Qt Creator, deleted the pro.user file, restarted Qt Creator, run QMake, guess what? Same message.

SPlatten

After loosing several hours of messing around with this, what can I do so I can start working again, I've deleted the build folder many times, I've restarted Qt Creator many times.

I'm going around and around in circles:

No rule to make target 'XMLMPAM'. Stop.

J.Hilk

@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?

@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.
