    I’m trying to debug a executable on a UNIX machine with Visual Studio, but I get always this error, why?

    Undefined MI command: list-features
    Undefined MI command: inferior-tty-set
    mi_cmd_break_insert: Unknown option f”
    Undefined mi command: file-list-exec-source-files (missing implementation)
    Undefined mi command: file-list-exec-source-files (missing implementation)

    Hi,

    Looks like your gdb version does not support some of the gdb/mi commands used by VisualGDB. Normally, updating to gdb 7.0 or later (although we recommend the latest 8.3.1 release) should solve the problem.

    I’m using GNU gdb 6.1.1

    But it still does not work.

    Sorry, VisualGDB does not support GDB 6.1, as it is more than 15 years old and is missing many critical functionality. If you absolutely have to use this version, we could add limited support for it as a custom paid feature. Please contact our sales to get a quote.

    I have now installed a never version of GDB which is supported. Now the mi issue does not exist anymore.

    But I get the error “Failed to start DGB Session.” “^error,msg=”Couldn’t get registers: Device busy.”

    Looks like you are referring to the this thread.

    We have mentioned that the oldest version of FreeBSD tested with SysprogsSync was 9.3. Once you provided more details, we pointed out that the error was caused by a 32-bit build of FreeBSD, and that using a 64-bit build, or patching SysprogsSync as we suggested, would solve the problem.

    If you do not have any specific version constraints, please try using a 64-bit build of the latest FreeBSD. Although some minor functionality may not work as expected, most of the functionality should work.

    It also looks like your forum account is using a different email address that is not linked to your license key. Please let us know the email address associated with your key via the support form, or update the forum profile accordingly, so that we could link it to your support profile.

    Edit: the latest error looks like the latest gdb might not be compatible with the FreeBSD version you are using. Sorry, unfortunately this is outside of VisualGDB’s control. Please try installing the latest 64-bit FreeBSD as suggested above.
