Debugging with mingw64 impossible
pozzugno:
I installed mingw64 under c:\mingw64.
In the compiler setting I copied "GNU GCC Compiler" configuration and renamed it to "mingw64". I changed "Compiler's installation directory" to c:\mingw64 and changed all programs (for example, C compiler is x86_64-w64-mingw32-gcc.exe).
In Settings->Debugger I copied Default configuration to a new one, renamed to mingw64. I changed the Executable path to C:\mingw64\bin\gdb.exe.
Again in Settings->Compiler I changed Debugger to mingw64.
I created a new Hello world project that uses mingw64 compiler. Compilation is fine and the program works well.
If I set a breakpoint inside a while loop and start debugging, the program halts to the breakpoint. If I press F8 (Start/Continue), the program halts again the breakpoint (it's in a while), so all is ok.
The problem happens if start debugging without any breakpoints and, during execution, I set a new breakpoint. The Debugger Log says:
--- Code: ---Trying to interrupt process with pid: 7472; child pid: 7472 gdb pid: 7708
Continuing...
--- End code ---
however the program will not halt anymore. It seems the debugger has lost the connection with the process. When I terminate the process, the debugger says:
--- Code: ---[Inferior 1 (process 7464) exited with code 030000000472]
The program is not being run.
Debugger finished with status 0
--- End code ---
This is the full log:

Codeblocks version is 17.12.
pozzugno:
Ah, another thing. If I changed the Project's Compiler to GNU GCC Compiler (that points to c:\mingw that is the original 32-bits compiler), everything is fine.
pozzugno:
Maybe the problem could be that my C::B (downloaded from here) is 32-bits and I'm debugging a 64-bits program?
Mistahboom:
Yeah, that's probably what the issue is ^-^
Downloading from the official website is probably the safest route haha
Yes! I'm learning as well and I'm rigidly following tutorials on Youtube and random articles, that I find online. I didn't experiment with any other compiler, and the teacher I follow recommended that default compiler.

I know, but I need mingw64 to compile mbedTLS libraries (mingw32 doesn't work without patches and someone suggests mingw64 should be the toolchain to use to compile mbedTLS).
Now I don't know if it's better to try patching mbedTLS to compile with mingw32 or compiling CodeBlocks for 64-bits architecture (I don't think CodeBlocks binaries for Windows are available).
