During the installation process of snort source code, you need to install daq and dnet. Here I want to talk about how to install daq. daq is simple, download the source code and install it directly. During the installation process, dnet always thinks about searching online after an error, but it is very disappointing. This article not only records a bug in the installation process. It makes me realize that I have to overcome my laziness and find a solution after encountering problems. ##daq installation process Let’s talk about simple daq first. We can see the installation process of daq from the official website/#get-started. ```wget /do…

1. Cause In the Vue webpack project with karma+mocha+chai as the test framework (I), it is explained that it is to build the test framework for existing Vue projects and test it.

There are several filters in design mode, namely the input box with "Filter" written on it, which can help you find the required parts faster. 4. If the generated .exe file cannot run and prompts that the .dll file is lost, you can press...

Introduction There are three ways to run applications created through the SDK: on the desktop, on the networked Ubuntu device, and in the emulator. These are complementary ways, as each has its pros and cons. You will first understand how to manage the device type of the SDK and which one is used to test different aspects of the application. Setting up the device toolkit Device toolkits are an important concept of the SDK: they enable you to generate applications for several devices and architectures, regardless of your development environment. If you haven't added any device toolkits, don't worry, you can always create new toolkits when you start a new project. Check out the files on the toolkit to learn more about these types, or just follow the next steps. When creating a project for the first time, S…

The author recently used Qt to develop some mini programs. I think this framework is really good, and I used signals and slots to solve it.ComponentsThe communication problem between them can be said to be based on a very big innovation in the C++ language, which greatly improves the coding efficiency of developers and makes the entire C++ language more abstract. The author likes the simplicity, simplicity and efficiency of the C++ language. Unlike .NET, even a small program needs to install a hundred megabit runtime library. For many scenarios, .NET is useless... A fast, stable, simple and efficient programming language must be the favorite of developers in the future. Okay, let's not talk about the problem in the question. There are two ways to solve this problem: Method 1: The author uses the latest version...

Due to project needs, different versions of qt programs may be run on the same machine. This experiment is that the programs developed by qt4.8.5 and qt5.3.1 are run on the same machine at the same time. This machine can not follow any version of qt. Of course, the number of bits of the qt developed by both versions must be the same as the machine, for example, both 32-bit or 64-bit. I use dynamic compilation for both versions of qt programs (please ask Du Niang for static compilation methods), so I need to put the dynamic library required to run the program in the place where the program can be linked. The dynamic library paths that the program can be linked are: linux dynamic library search paths. Here, it is directly posted: The order of searching paths for the search paths of the dynamic library are: 1. The dynamic library search path specified when compiling the target code...

Qt Creator on WindowsdebuggerInstallation and Configuration If you are using a pre-compiled version of Visual Studio when installing Qt, it is very likely that the debugger (Debugger) will be missing, and the native debugger corresponding to Qt using MSVC is CDB (the corresponding Qt of MinGW uses the GDB debugger).

Solutions for the QT console program not running under Ubuntu and the configuration method of XTerm Recently, the teacher asked to process the development of a multi-threaded server on QT under Ubuntu. Although it was just calling the qt network module, in order to avoid trouble, I still fucked writing the console program under QT, but after writing the program, the following situation occurred when running. The program was run, but there was only one cursor in the console jumping there. Due to the wrong posture of Baidu, it was useless for a lot of time. Finally, I realized that it was because the qt creator does not support the default terminal gnome-terminal of Gnome. So I had to change to the XTerm console. The specific solution...
