Debugging the program in Xcode

Hi, ALL,

I have a weird problem.

When I started working on my project I had a laptop with OSX 10.8. I installed Xcode 5 and everything was good. I was able to run the program from the Xcode and everything was working fine.

However recently I bought myself a newer Apple laptop with OSX 10.13. I installed Xcode 9.4.1, cloned my repository, opened the xcodeproject, compiled it and tried to run it.

Unfortunately the program failed to start. All I see that it stops somewhere in the assembly code, even before hitting any source code I wrote.
However when I open the Terminal and do:

Code Block open my_program.app

I am able to execute it without any issues.

I am also able to run the program from both Xcode and the Terminal when I update the code on my old laptop.

My question would be - what I need to do in order to start working inside Xcode and not keep switching between IDE and the Terminal for testing?

Thank you.

Is it MacOS or iOS on simulator ?
I understand it is MacOS app.

Could you show your applicationDidFinishLaunching code ?

Which exact version of MacOS is it ?
Did you try create a new program (with Xcode 9.4) and see if it launches from Xcode ?

@Claude31,

Yes, it is MacOS Application Bundle.
The code I'm trying is exactly the same. I'm using C++ with wxWidgets to make my application.
The new laptop has OSX 10.13.6 installed with Xcode 9.4.1.

The program contains of an application executable and 13 dylib projects, bundled in one Xcode workspace.
Maybe when Xcode launches the binary it can't find one of the dylibs and fails to run the Bundle?

But then why this doesn't happen on the old Mac.

Thank you.

Unfortunately not, that's one of the (many) problems of this forum

Could well be, libs may not be compatible with newer version of OS.
Have you the source code for the libs ? If so, did you try to recompile ?

Note: with 10.13.6, you could use Xcode 10.1

@Claude31,

With the old forum design that was possible. That's why I asked.
But more importantly - that's how all forums work.

Apple should fire their designers and hire someone who understand what users need. ;-)

Yes, the library are part of the workspace and are developed by me as well.
And yes - I did recompile everything.

The question is - where do Xcode expects to find them? /use/local/lib? Somewhere else?
And why it still works on the old Xcode?

Thank you,
