Re: Mac OS use of ddd

[Adanna Eziri]

Thanks,

I was looking up solutions online and came across a similar explanation. 

Do you have any recommendations for a gdb debugger gui that is compatible on 
MacOS?

I’ve been sifting through forums online but they all seem similarly outdated. 
If i just have to deal with the standard gdb output format, I feel comfortable 
doing that, just looking for alternatives! 

Best,
AE
