### Crossbuilding a compiler

Using a cross-compiler to build GNU Pascal results in a compiler binary that runs on the cross-target platform. This is called “crossbuilding”. A possible reason why anybody would want to do this, is when the platform on which you want to run the GNU Pascal compiler is not self-hosting. An example is mingw32.

To crossbuild GNU Pascal, you have to install a cross-compiler for your target first, see Cross-Compilers.

As when building a cross-compiler, configuration and compilation of the compiler can be done using the scripts `cfgpc` and `mkgpc` which are included in the source distribution in the subdirectory `p/script`. Please call them with the `-h` option for instructions.
