I think that's for configuration or
nvram
,hiscore
storage, but not dedicated ROM storage.Yes, the symlinks are for nvram, hi, etc. but they are still not used in the config file (see here).
Updated the script again. Really want to nail down the (sub)system issue. I really appreciate the ongoing feedback! Thank you.

Which issue ? (you might have mentioned it during this topic, but I can't remember it).
-
Hahah, yes this thread is getting long. Just the issue of not having arcade/mame as a (sub)system.
-
@George I though you were referring to something like adding command line parameters for starting
mame
as a different system emulator, likelr-mess
does for multiple systems. -

Apologies for the confusion. I'm not trying to do anything like that. But I do want to make sure the script is as clean and conformant as possible.

Quick little update. I successfully built MAME on my Intel/Ubuntu RetroPie installation with the script. Things are looking good.
I have not been able to get cross-compiling to work though. Am I correct in my understanding that I should be able to cross-compile MAME for ARM/Raspbian Stretch on an Intel/Ubuntu machine? On one post I read that it might not be possible because of a large number of dependencies.
I get the following errors:

Again, thanks as always.

Yes, that should work. While not specifically for MAME, I did cross-compile
lr-mame
andlr-mess
, but not using the RetroPie provided scripts - though it certainly should be possible.
What Ubuntu version and architecture are you using for cross-compilation ? -
@George it might be a good idea to only include playable drivers when building mame for pi, i don't see the point of having all those 3d/preliminary drivers that will never run at playable speed on a rpi, except if you really want to compile for 2 days and a half, and exhaust your ram and disk space with huge executables.
For the remainder, it is described at https://docs.mamedev.org/initialsetup/compilingmame.html
You can do driver specific builds by using SOURCES=<driver> in your make statement. For instance, building Pac-Man by itself would be make SOURCES=src/mame/drivers/pacman.cpp REGENIE=1 including the necessary REGENIE for rebuilding the settings.
Ofc, it would mean managing a list of those drivers

The driver list could be generated by script but yeah of course someone's then got to write the script :|
-
@George I did try to cross-compile from an Ubuntu 18.0.4 host and it seems to work, but there's one gotcha - you need to copy your scriptmodule to the chroot that gets created. So the steps would be
# build the cross-compiler sudo ./retropie_packages.sh crosscomp setup stretch # Compile one small package in the chroot, to get it created sudo ./retropie_packages.sh builder chroot_build module lr-picodrive # Copy your scriptmodule to $HOME/RetroPie-Setup/tmp/build/builder/stretch/home/pi/RetroPie-Setup/...., then run the cross-compilation. sudo ./retropie_packages.sh builder chroot_build module mame
Note that the builder will cross compile twice - for RPI 0/1 and for RPI 2/3. I haven't figured out how to compile for one platform only, but you can modify the builder script to exclude the platforms you're not interested in.
Some steps in the MAME compilation will be executed completely on the ARM chroot (.lay
files 'compilation'), they won't get any significant speed up from cross-compilation, but overall it should be considerably faster to get a PI build using cross-compilation.Leaving aside the cross-compilation, I have just one suggestion for your scriptmodule - you're currently hardcoding the MAME tag release, but you can get the latest release tag dynamically from Github. Look at how this is implemented in the
Skyscraper
module, here and here. -
Thanks for the info @mitu. I've been trying to get a handle on why this is not compiling. I'm still getting stuck at that first step:
sudo ./retropie_packages.sh crosscomp setup stretch
This fails while building libgcc
Makefile:883: recipe for target '_gcov_dump.o' failed Makefile:883: recipe for target '_gcov_flush.o' failed Makefile:883: recipe for target '_gcov_fork.o' failed
Here's some info on my platform:
$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 18.04.2 LTS Release: 18.04 Codename: bionic
The processor is an AMD processor and not Intel though. Not sure if that would actually make any difference here though. There don't seem to be any errors that would indicate a missing dependency either.
@barbudreadmon and @markwkidd, yeah the script could be modified to only include specific drivers. That would need some experimentation to see how much it would reduce the compile time. Thanks for the info.

The CPU doesn't make a difference, I actually run this also on an AMD, with the same release of Bionic. Must be something else I've run before that made the setup work.

This is pretty hard to track down, but I think I've made some progress. I ran apt update/upgrade a couple of times just to be sure I had everything up to date. Perhaps something had not gotten upgraded in my previous attempts. Now, it looks like everything is compiling, but the last step is still failing:

I'll dig in some more and see if I can resolve it.

@George Install
distcc
manually on the host. -
Ah, on a whim, I ran apt install distcc and it looks like that might be the missing piece. Taking a look at the original post I find evidence that this might be the case.

I believe I've gotten past the first step. Now, I'm trying to do the following:
sudo ./retropie_packages.sh builder chroot_build module lr-picodrive
But it gets caught at:
= = = = = = = = = = = = = = = = = = = = = Running action 'chroot' for 'image' : Create/Manage RetroPie images = = = = = = = = = = = = = = = = = = = = = Chrooting to /home/myuser/Downloads/RetroPie-Setup/tmp/build/builder/stretch ...

I note that my RetroPie-Setup directory is not in the user's home directory, but under a secondary Downloads directory. But
/home/myuser/Downloads/RetroPie-Setup/tmp/build/builder/stretch/home/pi/
is created at least.- George

I installed RetroPie-Setup on the host (i.e. like a PC installation - see the docs) - maybe that makes a difference.

Gotcha. When the script was downloading stretch, I mistakenly thought that was the RetroPie build.
So I'm starting out with:
cd /home/myuser/Downloads/RetroPie-Setup/tmp/build/builder/stretch/home/pi/ git clone --depth=1 https://github.com/RetroPie/RetroPie-Setup.git
I'm wondering if I need to run the Basic Install process and if that needs to be in the chroot'ed environment as well. Going to try without first.
Thanks for all your help @mitu.

Looks like it's doing more than it did last time, but I see a lot of the following warnings:
distcc[4372] (dcc_build_somewhere) Warning: failed to distribute, running locally instead
Is this something to be concerned about?

:( it means it's compiling in the chroot, instead of sending the compilation to the host (via
distcc
). Might be as slow as on a Pi (but without the swapping).
