macOS support?

[XNinety9]

Hi!

I tried giving gdbfrontend a test drive on my macOS laptop this morning, and was only treated with an error message:

GDBFrontend v0.6.1-beta

Any help is greatly appreciated 😅

Looks like we need a gotty executable for macOS 🙂 I'm currently working on a new feature, I'm going to stash it and look this issue. 👀

[rohanrhu]

I've added MacOS executable for Gotty.

Can you try macos-compatibility branch?: https://github.com/rohanrhu/gdb-frontend/tree/macos-compatibility

[rohanrhu]

I will do stuffs about MacOS compatibility on macos-compatibility branch if it needs.

That was quick, thank you!

I launched gdbfrontend from the cloned repo (I was using brew), and I get this new error:

./gdbfrontend: line 10: realpath: command not found
python3: can't open file '/run.py': [Errno 2] No such file or directory

[rohanrhu]

Ah looks like realpath is not available on Mac shell.. I'm looking.

Were you running with python3 run.py ? So is it working on Mac now?

[rohanrhu]

Hi, I've added a custom realpath for Mac shell. Can you try the latest revision? https://github.com/rohanrhu/gdb-frontend/commit/04c4f1a8e352ef59f23e7b3fb247fca5cd74abf4

New error:

GDBFrontend v0.6.2-git
Traceback (most recent call last):
  File "/Users/x99/Desktop/gdb-frontend/./run.py", line 350, in <module>
    gotty = subprocess.Popen(

    raise child_exception_type(errno_num, err_msg, err_filename)
PermissionError: [Errno 13] Permission denied: './bin/gotty_macos'

Ran chmod +x bin/gotty_macos, got this one afterwards:

GDBFrontend v0.6.2-git
Traceback (most recent call last):
  File "/Users/x99/Desktop/gdb-frontend/./run.py", line 350, in <module>

    raise child_exception_type(errno_num, err_msg, err_filename)
OSError: [Errno 86] Bad CPU type in executable: './bin/gotty_macos'

Replaced bin/gotty_macos with the one I had installed from here using brew install yudai/gotty/gotty, got this:

GDBFrontend v0.6.2-git

Are you sure for the port is available? 🙄

Also can you send outputs of these commands:

ps -e | grep gdb

tmux ls

tmux a -t gdb-frontend

If you don't see anything, add while True: pass to end of the file: https://github.com/rohanrhu/gdb-frontend/blob/7b9d2c2cab01489d2f86c93b6e9021fe87bd897e/gdbfrontend.py#L69-L71 Like this:

and later, try again ./gdbfrontend by ensuring the port is available and look to tmux a -t gdb-frontend output.

If we can't catch it with this way, I will do something for you to get some errors from tmux session.

Hi, any progress? I'm not able to test it on macOS since i don't have a mac.

[XNinety9]

Hi! No progress yet, no time to test right now. But I will soon 😉

Ok. Have a nice day 🙂

[rohanrhu]

This issue must be fixed. Also there was this issue: https://github.com/rohanrhu/gdb-frontend/issues/37 it is fixed too.
