Cross-development environment

Using GNUPro Toolkit in one of the cross-development configurations usually requires some attention to setting up the target environment.

A cross-development configuration can develop software for a different target machine than the development tools themselves (which run on the host)—for example, a SPARCstation can generate and debug code for a Motorola Power PC-based board. This process is known as embedded development.

For GNUPro tools to work with a target environment (except for real-time operating systems, which provide full operating system support), set up the tools with the help of the following documentation.

To set up the C run-time environment, see The C run-time environment (crt0).

Use the crt0 (C RunTime 0) file which contains the initial startup code for embedded development.

To use linker scripts for embedded applications, see The linker script.

To create stubs, or minimal versions of operating system subroutines for the C subroutine library, see System calls in GNUPro C Library in GNUPro Libraries.

To understand the connection to the debugger, see Specifying a debugging target in Debugging with GDB in GNUPro Debugging Tools.
