Compiling ScummVM with GCC under Linux
Installing the needed libraries via a package manager
The following should install all the needed libraries:
apt-get install g++ make libsdl2-dev liba52-dev libjpeg62-turbo-dev libmpeg2-4-dev libogg-dev libvorbis-dev libflac-dev libmad0-dev libpng-dev libtheora-dev libfaad-dev libfluidsynth-dev libfreetype6-dev zlib1g-dev
Some distributions, like Ubuntu, do not provide the turbo version of libjpeg. In this case, simply install libjpeg62-dev instead of libjpeg62-turbo-dev.
For Ubuntu, you can also obtain libunity:
apt-get install libunity-dev
The following should install all the needed libraries (apart from fluidsynth):
yum install gcc-c++ make SDL-devel libjpeg-turbo-devel libmpeg2-devel libogg-devel libvorbis-devel flac-devel libmad-devel libpng-devel libtheora-devel faad2-devel freetype-devel zlib-devel
Arch Linux-based distributions
The following command installs the compiler toolchain and all the needed libraries:
pacman -S --needed base-devel git curl faad2 freetype2 flac fluidsynth libjpeg-turbo libogg libvorbis libmad libmpeg2 libtheora libpng nasm readline sdl2 sdl2_net zlib
Per default, some Arch based distributions like Manjaro and Antergos require the usage of "sudo" to gain root access.
Run the configure script - type "./configure" in the directory with the ScummVM source files. If no errors come up, you should be ready to compile ScummvM. Run "./configure --help" for a list of optional features (eg additional, not yet enabled engines).
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.
run "make clean" and then "make"
either run ./scummvm from the current directory or run make install to install ScummVM (you can then run it using "scummvm" from any directory)
