Investigating stuck compiler

[J.Hilk]

@jsulm yes, from what I can see, MainWindow.cpp. It's 12000 line long.
Don't ask why😑 , my contribution to it is minimal or it would be significantly smaller.

[jsulm]

@J.Hilk Maybe you can comment out as much as possible and if it compiles uncomment small pieces until it hangs again?

[J.Hilk]

@jsulm mmh, possible. Will take me a while to do it, but I'll give it a try.
Could very well help narrowing the issue down.

You could also use git bisect if this issue began showing up recently.

Are you using jom ? When I've had compile problems I set to -j1 to remove the multiple jobs.

[J.Hilk]

So some updates 😆

Sadly no, it never compiled (release) for armv8 successfully

Yes I do, running 4 parallel jobs, I went and reduced it down to only 1 task running. Sadly no difference.

I went as @jsulm suggested and commented stuff out.

In the end, I had only the constructor the destructor and and the (designer) ui file/setup in the mainwindow class.
And the Compiler was still stuck.

So I removed the ui part as well and now it works....

This can only be the UIC that's causing trouble. Right? But I don't understand why it's only with this particular precompiled Qt the case.

I should now be able to make a minimal example, with some effort, maybe time to bring this to an actual bug report.

actually, simply removing

ui->setupUi(this);

makes the compiler complete its task. The app is unusable of course. x) but It compiles.

"Dude. It compiles." https://thedailywtf.com/articles/Flawless-Compilation

Jokes aside, what happens if you manually copy the UIC-generated code into your files?

[J.Hilk]

So,

I removed about 1/3 of the (QWidget) ui and replaced it with QML based code. Was on my to do list anyway.

And low and behold it now compiles for armv8. It takes about 8 minutes compared to armv7 2min, but I can live with that.

Haven't tried that, setupUi is like 15k lines long, so I didn't really want to mess with that x)

Sigh.

Double sigh.

@aha_1980
what can I say, the original designer made everything with the QtDesigner in one single ui file.

Since then I have started splitting sections of,
but it's a big application 😟

[aha_1980]

@j-hilk I feel with you.
