Compiler vs. Cross Compiler: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on January 24, 2024
A compiler translates code from a high-level programming language to machine code for the same system, while a cross compiler does this for a different system.

Key Differences

A compiler is a software tool that converts code written in a high-level programming language, like C++ or Java, into machine code that a computer's processor can execute. A cross compiler, on the other hand, performs a similar function but is designed to produce machine code for a different type of system than the one it's running on.

The primary use of a compiler is to translate source code into executable code on the same platform, ensuring the program runs efficiently on the target machine. Cross compilers are essential for developing software for systems that are different from the developer's hardware, such as applications for embedded systems or different operating systems.

Compilers are integral to software development, enabling programs to run on specific architectures and operating systems. Cross compilers facilitate the creation of software for platforms that may not support direct compilation, like developing Windows applications on a Linux system.

Both compilers and cross compilers essentially perform the same task of code translation, the key difference lies in their target platforms. Cross compilers are particularly useful in scenarios where the target platform is less accessible or has limited resources, such as in the case of embedded systems or game consoles.
