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. | 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.

''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. | |||
