Hello!
We are developing a math - library for realtime applications and want to
use some given mathlibraries as base(ipp, MTL, .. ). Our library is a
wrapper for those and you should be able to select the underlying
library by template parameter. Therefore we split up our library in two
namespaces:
The first one defines namespace-global functions which call the
baselibrary functions. These are templatefunctions which some

Hi,
I'm using "flex" which is creating a file called lex.yy.c and this
C file is added to a library. In another directory I have to use flex for
another file and also add the second lex.yy.c to another library.
Hence, I need to include both libraries and while linking I get an
e.g. "multiple definition of `yyleng'" since yyleng is created in both
lexx.yy.c.
I can't change the variable name yyleng since it's

Similar problem to the previous post. I have created a project with
about 7 files including 3 header files and 3 implementation files. I
am getting a multiple definition error when compiling for one specific
file of class. I have checked that if there is more than one
allocation of storage for identifiers, this error arises. But I don't
see where the problem lies. Any suggestions?

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...

Overview:
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,...

Hello
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...
