When you have suitable cross compilers available, you can cross compile your programs for processors and operating systems different from the system where KDevelop and the compiler is running. The GNU compiler collection gcc can be configured and compiled as a cross compiler if you compile it yourself. Consult the GCC info pages for more information. Some Linux® distributions also provide binary packages.

An automake based package can easily be cross-compiled by specifying the --host option to the configure script and setting the CC and CXX environment variables to the respective cross compiler binaries. Often you want to switch between a the cross-compiled version of your application and one compiled for your development system. For this, it is advantageous to use KDevelop capability of creating multiple build configurations, as explained in the section called “Multiple Build Configurations”. Once you have created a new build configuration for cross-compiling in the Project->Project Options... dialog, add the option

--host=platform

to the configure options. The platform name is a tuple of the form

cpu-vendor-os

or

cpu-vendor-kernel-os

For many combinations, you can use a short form, for instance i386-linux or arm-elf.
