The use of Linux friend book compiler gcc/g++
1. Program translation process In C language, we have already learned the compilation and linking of programs. Here we will review what we have learned before and introduce the subsequent content of gcc/g++. Translation process of 1.1 program Preprocessing (header file expansion, comment removal, macro replacement, conditional compilation) Compile: Turn C into assembly language Assembly: […]

26 | Easylogging++ and spdlog: two useful logging libraries
In the previous lecture, I introduced two libraries that can be used for unit testing in C++. Today, similarly, I introduce two practical logging libraries, namely Easylogging++ and spdlog. Easylogging + + In fact, I originally wanted to introduce only Easylogging++. But when checking its GitHub page, I discovered a problem: it has basically not […]

Cross-compiler naming rules and detailed explanation (arm/gnu/none/linux/eabi/eabihf/gcc/g++)
When engaging in embedded development under Linux systems, a cross-compiler is definitely an essential tool. When used in many situations, you will see various compilation tools, such as: arm-linux-gcc arm-linux-gnueabi-gcc arm-none-linux-eabi-gcc arm-none-symbianelf-gcc arm-none-uclinuxeabi-gcc arm-none-linux-gnueabi-gcc arm-cortex_a8-linux-gnueabi-gcc mips-malta-linux-gnu-gcc Do you know why these compilation tools are called so, what their respective meanings are, and in what situations […]
