Hello,
I struggled with the problem of "undefined reference to `vtable ...`"
while migrating a project from windows to linux. After searching the
google I removed all the inline functions and now the link errors
decreased from over 200 to 5. A great step!
But one of my class derived from wxValidator can't be linked correctly
though there is no any inline function in it.
The error message:

Compiling my current project I received the following error:
undefined reference to `vtable for Tuner'
The only two things I know are that the error occours when trying to invoke
the constructor of a class and that concerns virtual functions.
What does it mean?

Hi,
I'm trying to write some classes that kind of manage themselves. A
linked list, that links different types of objects. Here's the code...

Hi,
Iam facing problem with undefined reference linking errors.
To explain in more detail..
I have a class called TOP. In its constructor I have instantiated many
other class objects using pointers.
Iam getting errors like
1. In function TOP::TOP(int) : undefined reference to
CHILD1::CHILD1(int, float).
2. In function TOP::TOP(int) : undefined reference to vtt for
CHILD2::CHILD2(char*)

I read google and tried to find the solution myself. YES I do know that
you can get undefined references if you:
a) forget to implement the code for a prototype/header file item, or
b) you forget to pass all the necessary object files to the linker.
Neither of those are my problem. Please bear with me as the question
I ask is rather long and I think it's beyond a CS101 level of linker
stupidity. If it is a stupid CS101 mistake I'm making...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
