Home Page Forums MAME MAME Can't compile latest MAME? READ THIS THREAD

It shouldn't be using more memory than 0.227 to compile as far as I'm aware. Maybe something else running is using a lot of memory?

Okay, this time I took a closer look at running applications and memory usage at compile-time and tracked the issue to something on this end. Thanks for your help in sleuthing this out.

I have a possible noob compiling question here.
I'm trying to compile a very specific build of MAME (handheld games only). I can set it to the specific drivers easily enough which eliminates most of what I don't want, but some drivers have things in them that aren't games (like hh_tms1k.cpp has a bunch of TI Calculators). I'd like to remove individual games from a driver during compile. Is there an easy way to do this?
Do I have to comment out parts of the driver itself (is just commenting out the game drivers lines at the end of each one enough?) or can I set up something during the compile to just ignore some? (That would be ideal so I don't have to keep altering the drivers when I pull down updates from .git...)

You can comment out the GAME() or CONS() or COMP() macros at the end of the driver for starters, but then you'll most likely wind up with errors related to symbols defined but not used, since there will now be functions that are implemented but not used by anything. So you'll probably need to follow the errors down a bit of a rabbit hole until you've commented out enough things to make the compiler happy.

I tried compiling mame from git but early on in the process I get this:

I used the following commandline:

Any ideas?

Probably shouldn't leave your surname showing there... just saying.

Still no luck with this.

From which path are you invoking make?

Are you doing this from the MinGW command line? The forward slashes in that error message would seem to indicate that you're in some other type of shell.

Have you tried it without all of the non-standard things you're adding to the make invocation?

It seems like you're trying to do it in a way other than the officially documented method, so this is a "no warranty" situation.

On Ubuntu 20.04 I had to get help on getting the update tools for compiling MAME. Cesare Falco help me out on which ones need to be change.

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

to this

sudo apt-get install git build-essential python3-dev libsdl2-dev libsdl2-ttf-dev libfontconfig-dev libpulse-dev qtbase5-dev

Reason why.

E: Package 'python' has no installation candidate
E: Package 'qt5-default' has no installation candidate

Way too slow on compiling on my dad laptop. Intel core i5 with 6gb of memory. I tried the -j3 and it just crash the terminal. I just use make without it. Took over 5 hours.

So far no issue on running MAME. I just right click on the home/mame0246 and then bring up terminal. Type in mame and then hit enter to load it. Or just right click on mame file and then click on run to load it. Ether way.

mame -j2 works fine. I tested this yesterday on Ubuntu. Just can't use the -j3.

My guess is that the 6GB of memory isn't good enough. Need 8GB on the laptop so it can keep going without the terminal crashes.
