For example, every target platform needs a different file system.ppu (System unit), etc. These are the binutils.Īfter creating (or having/installing) the cross tools, one needs FPC RTL and other units compiled for the chosen target platform. That's why we have to use different special linker 'ld' and assembler 'as' for every target platform. Usually these tools are not able to create binaries for different platforms. FPC provides an internal assembler and/or linker for some platforms, but other platforms need external tools. We also need the assembler and the linker.

See the Supported target operating systems article for the full list. FPC binary can then select the right compiler (either the native compiler or the cross-compiler) for the target CPU selected using the -P parameter.

Such a cross-compiler may be either compiled by yourself, or you can use a ready made distributed cross-compiler provided for some platforms directly by the FPC team (usually platforms mostly used in portable devices like arm-linux or arm-wince, because these are usually not used as host platforms). This cross-compiler is then usually stored in the same directory as the native compiler.

compiler running on the host platform, but able to create machine code for a different CPU (in the case of FPC, such a cross-compiler would be again able to target all supported platforms available on the _target_ CPU). If you need to create binaries for a different CPU, you need a special cross-compiler, i.e. This means that you can perform cross-compilation with the same compiler used for native compilation as long as you stick to the same CPU.

Just tell it to do so.įPC is designed so that the distributed compiler can create machine code for a certain CPU (because different CPUs need different machine code) and it knows specific requirements for all supported platforms (operating systems) available on that particular CPU. It can create binaries for many platforms.

Free Pascal itself does not need much setup. Therefore these binaries are platform specific. Moreover, the binaries refer to the APIs provided by the particular operating system, that's why a different implementation of our Run-Time Library is necessary for different operating systems. These binaries also contain information on how the operating system starts the executables. In this case, the platform used for compilation is usually referred to as "host" (Linux in the example above) and the platform where you want to run your created binaries is your "target".įree Pascal is a compiler and basically converts source into binaries (machine language). working under Linux and creating Win32 executables (or those for FreeBSD or Darwin, etc.).

The following sections describe how to setup a system to cross compile, that means creating binaries (executables) for a platform different from the one used for compilation - e.g. This is a short introduction for newbies. Note: Before going any further, consider Why not to cross compile? below
