Hello !
I have here template class with
static members. and I put definition of the static member in the same
..h file where the class was declared.
however, we are getting very stange errors, because static member
occupy same place as some other non-static variables. and so
application crashes. compiler somehow allocates same place for them.

I have a C++ template class which contains a static variable whose
construction registers the class with a map. Something like this:
template <typename T>
class M {
static Registrar<M> registrar;
};
The constructor of Registrar does the registering when it is initialized.

Hi, I really need some help here. After upgrading to g++ 3.4 I have run
into all sorts of troubles that I'm sure depends on my lack of proper
understanding of C++. I would now like to get it right once and for all,
if possible.
Most severe is the problem illustrated by the code below. It's based on
the "pluggable factory pattern" described in

Hi,
I was curious about how to define static data member of template class.
Should I put the definition in a separate source file or in the same
header file as its template class?
And when this data will be initialized if it is used across many
translation unit, assume that it has constructor and needs dynamic
initialization?
I have blindly searched for the answer but I still not thoroughly

The following code compiles cleanly, but it looks like gcc 3.4.0 does
not emit the static data member into the object file (so I get a link
error):
#include <iostream>
template <class Type>
class foo {
public:
foo( Type i )

Hi,
When modifying a data member in a class declaration, the static keyword
specifies that one copy of the member is shared by all instances of the
class.
Does that mean that the address of the data member is the same for
every instance of that class? I would expect so, but I noticed
something that makes me doubt a little.

Hi guys
Here's the class I try to compile (see below). By itself when I have a
test.cc file for example that creates an object which is an instance of
the class SpectralProfile, it compiles fine.
1 / Now If I move the getSpectrumAtDistance( const T &dist ) method
definition in SpectralProfofile.cc let's say the compiler says
core/profile.cc:199: error: `kNumBins' was not declared in this scope

Hello everyone, thanks in advance for your help. I'm new to C++
templates and have run into some issues using member function
templates. I have a shared library containing templates that I'm
trying to use from an executable, compile using gcc 4.1.2. Everything
works fine until I try specializing one of the static member function
templates in a non-template class. I have a feeling I'm messing up
something obvious so before I post a...

As we know, the keyword "inline" is a bit misleading because its
meaning has changed in practice. In most modern compilers it has
completely lost its meaning of "a hint for the compiler to inline the
function if possible" (because if the compiler has the function
definition available at an instantiation point, it will estimate whether
to inline it or not, and do so if it estimates it would be beneficial,
completely regardless of whether...

Hi all,
I'm having difficulties with some template static member, especially
when this member is a template instance, for example:

template<typename T>
class BaseT

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
Here is the code in...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
