Now we configure scummvm buildsystem so it knows what backend we want and where is our raspberry pi local sysroot living, containing the Raspberry Pi headers and libs the cross-compiler and linker will need. In this example configuration, we disable additional libs, and debug symbols since it's intended for final users.

Remember you should have exported the RPI_ROOT enviroment variable previously.

On the raspberrypi host, SDL2 will be always used since it provides graphics acceleration.

''Note:'' If you are building ScummVM on your RPi itself, you might run out of memory during linking. If you use GNU ld for compiling you can try exporting LDFLAGS="-Wl,--no-keep-memory" before running configure. This tells GNU ld to optimize for memory usage.
'''Note:''' If you are building ScummVM directly on your Raspberry Pi itself, you might run out of memory during the final linking process of the build. If you use GNU ''ld'' for compiling, you could execute the following before running ''configure'':
<nowiki>export LDFLAGS="-Wl,--no-keep-memory</nowiki>
This tells GNU ''ld'' to optimize for memory usage.
