What is cross-compilation and how do I get started?

Cross-compilation is the process of building executable code for a platform different from the one on which the compiler is running. To get started, you'll need a cross-compiler and the appropriate libraries for your target platform.

What tools do I need for cross-compilation?

You'll typically need a cross-compiler like GCC or Clang, and possibly a build system like CMake. Additionally, you'll need the libraries for your target architecture.

Can you provide a simple example of cross-compiling a C program?

Sure! If you're on a Linux machine and want to compile a C program for ARM, you might use a command like arm-linux-gnueabi-gcc -o hello hello.c.

What are some common challenges in cross-compilation?

Common challenges include dealing with different library versions, ensuring compatibility with the target architecture, and debugging issues that arise from the differences between environments.
