Does golang depend on glibc?

Golang (Go) is a modern programming language that was developed by Google in 2007. It has the characteristics of fast compilation, efficient execution, and simplicity to learn, so it has attracted much attention in recent years. However, for some developers, they have questions about whether Golang depends on glibc (GNU C Library). This article will explore this question and give an answer.

First of all, you need to understand what glibc is. glibc is the standard C library in Linux systems. It provides many APIs for system calls, process management, memory management and other system-level functions. It is an important part of supporting the operation of Linux systems. Since Golang itself does not depend on the standard C library, some people may think that Golang does not depend on glibc.

However, it is not. Since Golang uses some system calls and other operating system-dependent features in its implementation, this causes Golang to depend on some basic libraries. glibc is the basic C library that supports the Linux operating system. Therefore, glibc is required to use Golang programming on the Linux system.

You can use the following steps to verify whether Golang depends on glibc. First, we can obtain the source code of Golang, then compile it and disable CGO (C language calls Go), so that we do not rely on the C language dynamic link library, that is, we do not rely on glibc.

Next, we can use ltrace to track all dynamic link libraries called by the Golang program. In this process, we can find that the Golang program depends on some dynamic link libraries, including glibc. This shows that Golang does depend on glibc on Linux systems.

It should be noted that Golang's dependence on glibc is very small, mainly because Golang needs to use some basic system calls and other operating system-dependent features, thus indirectly relying on glibc. However, this does not mean that Golang should not run in environments that do not require glibc.

In fact, Golang can also run on embedded systems or other small devices, in which the standard glibc library may not be included. However, this requires ensuring that features and functions that require glibc are not used in Golang programs. If you need to use specific glibc features or functions, a better approach is to use CGO, which interacts the resources with the C language interface when these features or functions are needed, which makes it easier to handle dependency issues.

After summarizing the above, we can conclude: Golang does depend on glibc. This is because the Golang implementation uses some basic system calls and other operating system-dependent features. However, in special environments, CGO can be used for dependency management, thereby ensuring that Golang can run stably in various environments.
