Mame compile on Ubuntu 16.04 is pretty easy

I must be getting better at setting up compiling mame on a ubuntu 16.04 system because it seems pretty easy now.

I get the latest 185 version from http://mamedev.org/release.html

Look for mame0185s.zip MAME 0.185 sources in ZIP format (all platforms) and extract it with Archive Manager.


The instructions at:

http://docs.mamedev.org/initialsetup/compilingmame.html tell you what you need:

sudo apt-get install git build-essential libsdl2-dev libsdl2-ttf-dev libfontconfig-dev qt5-default

and then I edit the makefile,

where the line says

# QT_HOME = /usr/lib64/qt48/

I just add this line underneath:

QT_HOME = /usr/lib/x86_64-linux-gnu/qt5/


I like to see how long it takes so I run with time and -j4 for 4 processes since I have a quad core machine:

time make -j4

and it fails for some reason at the end, probably some race condition:

Running the make again is successful:

It takes me 38 minutes to compile on a quad core i5-2400 (3.1ghz x 4)

An Intel Core i3-2100 CPU @ 3.10GHz × 4 gives takes about 45 minutes.

and ./mame64 will run the compiled mame.
