GDB Problems with new install of GPS 2019 x86 64 Windows

[William Thomas]

Running Windows 10.
When trying to debug a simple Hello World main, I get this (three times).
Tried running it as admin, maybe I have to install as admin? Or maybe its a Python GPS command thing?

Any suggestions?

OK,

So I go into the file weakref.py and I comment out the following:

from _weakref import (
     getweakrefcount,
     getweakrefs,
     ref,
     proxy,
     CallableProxyType,
     ProxyType,
     ReferenceType) #,
#     _remove_dead_weakref)

I just removed the "_remove_dead_weakref" (kind of ironic) from the python import thingy and now it works. GDB fired up and I can finally start to debug my Hello World program. 

So like wow, I've been working with Ada, for the last several decades, and I must have missed it when the big snake came in and took over.

It seams like that big old snake can in a wrapped itself around everything. Can hardly see the Ada anymore. Oh well, the big snake must be cool, because everyone is using it. Heck it's even one of the big stars on Mr. Robot, so its got to be good, and good for you.

Thanks Bill.

I wonder whether you have python 3 installed? maybe running 3 with
2.7-related libraries causes trouble? (both 2.7.16 and 3.7.4 execute
that import on its own just fine).

No idea why GNAT CE includes so much gdb-related python; standard gdb
(8.3) such as I run on Mac with FSF GCC 9.1.0 doesn't.

Big snake? Big snake*s* (2.7, 3.6, ...) !
