Linux application best practices. How?

[bogong]

Hello all!

Is there any reference of how to develop Linux application in general and with Qt? Especially console server-like applications. Need to refresh my knowledge on this topic. Is there any articles or manuals?

My primary OS - Ubuntu 20.04.

Qt is cross-platform, so unless you have some very platform specific or 3rd party stuff, there is no "Linux"- or "Windows"-application, when using Qt.
The use of the Qt modules is 99% the same on all platforms.

I would start looking for "server/console applications" (depending on what your really want to do) and what libraries you might need/plan to use.

For the "Qt Networking" module and its classes, as always, check their documentation:

• https://doc.qt.io/qt-6/qtnetwork-index.html

It also includes guides:

@Pl45m4 Totally senseless reply. In my question mentioned exactly about Linux. Nothing more.

I am not aware of anything general or special for a "Linux application". A console application is just a console application, so actually nothing to say compared to, say, a UI application. Depends just what you want to do. And what you have in mind by "server-like".

@bogong Ubuntu 23.04 has come out. I think it is better to upgrade your Ubuntu to 22.04 or up if possible.

@JoeCFD OK, but why would that be relevant to a general question about writing some code for Linux?

[JoeCFD]

@JonB just a remainder. Nothing specific to Qt development. More modern C++ features are added in the newer versions of Ubuntu.

So we should read your thoughts and already know what "Linux-specific" things you want to do and what "server-like" application you are thinking of?!
Asking for a "Linux app" is like "I want to write a program" with no more information, esp. when mentioning Qt, which is mostly cross-platform, so the OS doesn't matter. And when it matters, it's most likely not a Qt-related question, which are also answered here, but the little information you provided, is not much...
So what answers did you expect?!
