What does linux cross-compilation environment mean?

Linux cross-compilation environment refers to an environment that compiles on one operating system for another different operating system or architecture. In a cross-compilation environment, developers can use a compiler and tool chain on a host system to generate an executable program or library on the target system.

The operating system of this tutorial: Linux5.18.14 system, Dell G3 computer.

The meaning of linux cross-compilation environment

Linux cross-compilation environment refers to an environment that compiles on one operating system for another different operating system or architecture . In a cross-compilation environment, developers can use a compiler and tool chain on a host system to generate an executable program or library on a target system.

Normally, cross-compilation environments are used to develop embedded systems or cross-platform applications. For example, if your development machine is a PC based on x86 architecture, and you want to compile and run the program on an embedded device with ARM architecture, then you need to set up a cross-compilation environment suitable for ARM architecture.

Setting up a cross-compilation environment requires the following key components:

1. Cross-compiler: This is a compiler for the target system that can Compile the source code into a binary file executable by the target system.

2. Libraries and header files: A cross-compilation environment requires libraries and header files on the target system so that these libraries can be linked and used correctly during the compilation process.

3. Toolchain: This includes tools for the target system, such as debuggers, linkers, and binary file format conversion tools.

When setting up a cross-compilation environment on Linux, you usually need to obtain a cross-compiler and tool chain suitable for the target architecture and add it to the system's environment variables so that when compiling Call these tools correctly during the process.

Cross-compilation environment setup may vary depending on the specific target architecture, development tools, and project requirements. Different cross-compilation environments may require the use of specific tools and configuration options. Therefore, when setting up a cross-compilation environment, it is recommended to refer to relevant documentation, tutorials, or guides for specific target platforms.

In summary, the Linux cross-compilation environment provides the ability to compile on one operating system for another different operating system or architecture, allowing developers to easily generate target system code on the development host. The program or library that is executed.
