Note:

If you are building ScummVM on a system with low main memory (for example, lower than 256MB), 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.

If you must (see below), use

Note on static builds:
 
If you are trying to build ScummVM statically linked (all-in-one binary) your system memory will likely run out during the linking process.
The currently available AmigaOS4 NG systems are limited to 2 GB of RAM (where the limit actually stops at roughly 1550 MB) on the OS level (this may change in the future, but right now i would advise against a natively build static binary. (Cross-compiled static builds are still available throught the ScummVM buildbot (https://buildbot.scummvm.org/#/), albeit not with all available features).

This will automatically install the ready binary with all needed dependancies into a subdirectory named "install/".


This directory can then be copied anywhere and used.
