Goodmorning everyone.

I have had a problem with my project for several days ... after reinstalling
the ubuntu on another machine I exported the current project where I'm working.

On this new machine I encounter this problem ... and I can't understand where ... it comes from.

Can anyone help me?

Thanks so much.

@AntonioValentin The error message already tells you what you're doing wrong: you're trying to return false in a function that returns a pointer. A boolean cannot be implicitly converted to a pointer. Return nullptr instead of false.

Also, please do not double post same question!

@jsulm

So what should you do?

Change from false to true?

if(!prog_file.is_open()) return false;

@AntonioValentin said in The process "/usr/bin/make" exited with code 2.:

So what should you do?

What I wrote: return nullptr instead of false.
"Change from false to true?" - I did not write that anywhere and it would not make any difference.
It is as simple as:

if(!prog_file.is_open()) return nullptr;

Hy,

modified the command mentioned above.

we say that the problem has been solved ... but in another file this error comes up.

@AntonioValentin
What do you want us to say? You have a load of messages, either warnings or errors, which you should sort out, or maybe change compiler flags if you really want to ignore and they are ignorable. Nobody here is going to go through each of these messages and guess how you should correct.

Plus you have been asked not to double-post in two forums but are still doing so, please do not....

@AntonioValentin said in The process "/usr/bin/make" exited with code 2.:

../agejet/rfid_worker.cpp:136:35: error: narrowing conversion of ‘250’ from ‘int’ to ‘char’ inside { } [-Wnarrowing]
char init_bytes[] = {0xFA,0x12};

250 is too big for char (which is signed). Use unsigned char.

And, please, keep in mind that you're asking questions completely unrelated to Qt. Use Google to search for your compiler errors/warnings, read a book about C++...
