Re: [cdt-dev] java.lang.AssertionError in GdbCliConsoleManager.stopConsole(GdbCliConsoleManager.java:103)
|
As for your original AssertionError, I have checked and CDT 9.3
(Oxygen) does not have that problem. The assertion is not present in
that version. Additionally, users running with Assertions off (no -ea
flag) won't have that problem.
As to your new exception, this is because CDT is having trouble
determining GDB version. Without assertions on it just falls back to
best it can do.
So I have a few questions:
1) If you run without -ea (as a user does) do you have the GDB console?
2) Do you have any log output like "Could not determine GDB version
using command" or "Error with command" as they are the messages that
AFAICT will be emitted at the root of the problem.
3) Can you include the output of gdb --version (for the GDB you are using)?
Thanks,
Jonah
