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 libsdl1.2-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
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
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).
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)
