0ad 0.0.23 on Jetson nano (ARM64)

[Dansasbu]

Hi, I'm trying to install 0AD on my jetson-nano. I have ubuntu bionic installed, and an arm64 architecture. I'm using this ppa: ppa: wfg / 0ad, but seems to lack the package 0.0.23b (only appear 0.0.23) for 0ad, while for 0ad-data and 0ad-common there are 0.0.23b. because of that an unmet dependencies error raises. What I can do? I'm trying to download the 0.22 version, but I couldn't find it.

If It's Ubuntu you can try to use the PPA

• See  0 A.D.-Provided Packages https://play0ad.com/download/linux/
• You can also contact your package maintainer.
• If the above doesn't work you can also compile it for source.

Let me know if it helps.

I don't think Alpha 22 exists anymore, though.

[Dansasbu]

I tried to compile from source. I followed this guide https://trac.wildfiregames.com/wiki/BuildInstructions, I downloaded the code with svn: 

svn co https://svn.wildfiregames.com/public/ps/trunk/ 0ad

Building with this flags:

./update-workspaces.sh --with-system-nvtt

I'm getting this error (when is building spidermonkey)

I tried to install spidermonkey first and then use the flag: --with-system-mozjs45

./update-workspaces.sh --with-system-nvtt --with-system-mozjs45

but I had exactly the same problem when building spidermonkey. I couldn't find a solution on the web. 

There is a way of install the game without spidermonkey? Or maybe work with another version of spidermonkey?

Thanks!

Spidermonkey is what the main engine uses to process the scripting language we use java script so no SM no game  BTW if you have Firefox installed then that is the system mozjs as in Mozzila js not sure which version the current FF uses.

Enjoy the Choice

In Ubuntu (bionic) repos I found this versions of spidermonkey: libmozjs-38-dev, and libmozjs-52-dev. But the game seems to need the 45 version of spidermonkey.

Looks like nobody tested on ARM ( I plan on getting a raspberry pi 4 soonish) 

To play with other A23byou need to revert to rP21945 which will require SM38

I'm sorry but I don't understand how to do that

 

Can you give me some guide? Thanks.

[Loki1950]

The instruction set for ARM CPU's is different than that of Intel and AMD CPU's which is what the source code is primarily targeted to the differences are small but significant so that what will compile on one platform may not on the other which is exactly what is happening here.

Enjoy the Choice     

[Stan`]

Run svn update -r21945 and try to compile again from source.

[Dansasbu]

Thanks Stan, I did what you say. I passed the step of update-workspaces, installed first libmozjs-38-dev and later using this flags:

./update-workspaces.sh --with-system-nvtt --with-system-mozjs38

However, running the makefile in gcc folder, I got this error

I don't know if all this checks are for play online, and there is another way to install the game to play against the AI only.

Can you try with the bundled version instead of the system's ?

[Dansasbu]

Whitout the flag --with-system-mozjs38, I got this error

@Itms @wraitii can you help ?

[Itms]

Hi! You seem to have hit this bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1266366

What is needed is to patch spidermonkey with it, and when it's committed, then you will be able to build SVN like you tried to do, with

Ideally we would have downloaded the latest bundle from the esr branch, instead of the release candidate from the SpiderMonkey devs, but they are not available anymore for SM45. So it would be better if you could test the patch that I will make, in case we need to patch more bugs. Are you comfortable with using our patch review platform? Else I'll provide the patch here and will give you instructions to test it.

Thanks for the report

[Dansasbu]

Many thanks for your help! I've never used the patch platform before, but I can try it.

[Stan`]

Let us know if you need guidance

[Dansasbu]

I'm very sorry . I need to create a Diff?

Yes only if you want to

[Dansasbu]

Ups, I think that I will take the another option and follow your instructions here.  

[Itms]

Here is a patch: https://code.wildfiregames.com/D2244

To apply it, you should use arcanist. If you are on Debian buster or later, just install it from the repository. Else follow these instructions: quick start.

Then, you can create an account on Phabricator (that will allow you to comment directly on the patch, to be pinged if we need some information, etc).

Then, in your terminal:

arc install-certificate

in order to use arcanist with your account, and then

arc patch D2244

in order to apply the patch. You can then build with

./update-workspaces.sh --with-system-nvtt
cd gcc
make

And please report here or on the patch directly if you discover other bugs

Thanks for the report, and in advance for testing and playing!

@Itms He wanted to play A23 too any way to fix his sm38 bug ?

He will also need to update to  SVN again.

[Itms]

I don't know how was the support for arm64 for SM38. Our version never worked there, but maybe it could be patched (it's too late for us though). We can help to find patches to bugs if they exist, but that will need some tinkering from Dansasbu. But this is a good opportunity to improve our arm support for A24!

Updating SVN is not needed to test the patch.

Well he reverted to A23b so it is

Yeah makes sense. I'll probably buy a RPI4 or a Jetson so we can test on those platforms before the end of the year.

Hi, I have some news! First, I updated svn to r22827 (I checked it by:  svn info --show-item revision), then I followed the Itms instructions. The patch worked very well, no errors reported. Running the automated tests also don't show errors (binaries/system/test), however when I tried to run the game I got this

Seems to be a bug of SDL2: https://forum.odroid.com/viewtopic.php?t=30652

I run the following and the game works

sudo killall ibus-daemon

However the game runs a bit slowly, I disabled some graphics options but the enhancement is small. I will play a little more and see how it feels. Many many thanks!
