Basic environment#

translater#

You first need to install some basic software packages, which are necessary to compile C/C++ programs.

Shell

sudo apt install build-essential

Of course, you can also install llvm, which is also a C/C++ compiler. Its advantage is that it can compile languages other than C/C++, such as Rust, Go, Swift, etc.

Shell

sudo apt install llvm # llvm backend compiler
sudo apt install clang # clang front-end compiler

Debugging tools#

Debugging tools are essential tools for programming. They can help us quickly locate program errors and improve the running efficiency of the program.

Shell

sudo apt install gdb  # gdb debugger
sudo apt install valgrind  # valgrind memory checking tool

Static analysis tools#

Static analysis tools can help us check program errors, such as memory leaks, null pointer access, etc.

Shell

sudo apt install cppcheck  # cppcheck static analysis tool
sudo apt install clang-tidy  # clang-tidy static analysis tool

Code formatting tools#

Code formatting tools can help us format the code to make the code style unified and improve the readability of the code.

Shell

sudo apt install clang-format  # clang-format code formatting tool

clang-format can be configured using a configuration file. The deepin community provides a configuration file that conforms to the deepin code style. You can find it here . However, it is recommended not to rely on this configuration file because this configuration file is based on the deepin code style. If your coding style is not deepin, then this configuration file is not suitable for you.

It is very important to have a good coding style. It can improve code readability, maintainability, scalability, reusability, testability, etc., so you should develop a coding style yourself and then use clang-format to format your code.

However, you should not rely too much on tools, because tools are extensions of humans, not replacements of humans. When clang-format cannot meet your needs, you should modify the code yourself.

.clang-formatFor details on the configuration file, please refer to the official documentation.

Code inspection tools#

Code inspection tools can help us check code errors, such as unused variables, uninitialized variables, etc.

Shell

sudo apt install clang-check  # clang-check code inspection tool

code coverage tool#

Code coverage tools can help us check code coverage, such as which codes have not been tested.

Shell

sudo apt install lcov  # lcov code coverage tool

Code compression tool#

Code compression tools can help us compress code so that the code takes up less space.

Shell

sudo apt install upx  # upx code compression tool

Build tools#

Build tools can help us build projects, such as compiling, linking, installation, etc.

Shell

sudo apt install cmake  # cmake build tool
sudo apt install meson  # meson build tool
sudo apt install ninja-build  # ninja build tools

text editor#

In fact, after the above software packages are installed, you can start writing C/C++ programs, but you also need a text editor. This text editor can be any, such as gedit, vim, emacs, etc. Here as a recommendation, I recommend several text editors

because#

Vim is a very powerful text editor with very powerful functions, but its learning curve is also very steep, so if you are a beginner, I do not recommend you to use vim.

Shell

sudo apt install vim

emacs#

emacs is a very powerful text editor with very powerful functions, but its learning curve is also very steep, so if you are a beginner, I do not recommend you to use emacs.

Shell

sudo apt install emacs

VSCode#

VSCode is a text editor produced by Microsoft. Its functions are very powerful, and its learning curve is not very steep, so if you are a beginner, I recommend you to use VSCode.

According to the open source agreement of VSCode, deepin cannot provide the installation package of VSCode in the source, so you need to go to the official website to download the installation package and then install it manually. Or (recommended) search for VSCode in the app store and install it. (This method will add the official software source of VSCode, so it will be much more convenient to update VSCode in the future)

Notepad--#

notepad-- is an open source cross-platform text editor. Its gitee project address is: https://gitee.com/cxasm/notepad--
