Installing a C++ compiler (usually <span>g++</span> or <span>clang++</span>) on UNIX/Linux systems is the first step in C++ development. As a typical UNIX-like system, most Linux distributions natively support or can easily install C++ compilers. Below, I will detail how to install a C++ compiler on popular Linux distributions (such as Ubuntu, Debian, CentOS, Fedora, Arch, … Read more
Generally, compilation requires support from library files. For example, static library files and dynamic library files. On Windows, .lib files are static library files. .dll files are dynamic library files. The suffix for library files is as follows: The suffix for static library files is .a. The suffix for dynamic library files is .so. The … Read more

Students, in the world of Linux, the gcc and g++ compilers are like “super craftsmen” in programming for informatics competitions, capable of “polishing” our written code into instructions that the computer can understand. Next, let’s delve into the usage of these two “super craftsmen”. gcc Compiler (primarily for C language) 1. Basic Compilation: Suppose you … Read more
Introduction: GCC/G++/GDB, The Programmer’s “Magic Wand” Hello everyone, today we will discuss how to compile and debug C/C++ programs. When it comes to GCC/G++, many beginners might first think: “Isn’t this just a compiler? Don’t you just write gcc main.c and hit enter?” But when compilation errors occur, they realize their understanding is as shallow … Read more
GCC (GNU Compiler Collection) and G++ are both compilers developed by GNU, but they have some functional differences. Although they belong to the same toolset, the main difference lies in the programming languages they support and how they handle the compilation of source code. Here is a detailed introduction and comparison of GCC and G++. … Read more
