lr-scummvm: request for comments and testing

BiZzAr721

I figured out why I had no mouse. I noticed other Retroarch cores had no mouse either, so I started looking at settings, and retroarch config. I erased all lines pertaining to input, and the mouse worked again. I couldn't narrow it down to exactly what caused the issue. I ended up abandoning my old crowded Retroarch.cfg and using the clean one from the RetroPie. Happy New Year!

I want to update emulator from Emulation Station setup, but it seems is not possible to complete installation, also tried to uninstall and reinstall but installation stil not complete, any suggestions?

takes a lot of time to rpi install this core hope works fine, i have one game that works weird with the default scummvm

@DarishZone I have a wired 250 mb line, and the download & build of the lr-scummvm core took a lo-oong time. Did you get any messages / errors?

mitu

@DarishZone What's the error ? Post the actual error and maybe we can find a solution.

I'm sorry but i don't have that, i'm pretty sure install, which is loong indeed, interrupt with some error on terminal then a message on Emulation Station, seems it not compile for some reason. I will eventually try again and takes some photos, thx!

@Dipkid me too same network aswell and faild to install..

Hi all! I've been traveling and didn't have time to catch-up the forum.
there were some recent commits to the lr-scummvm upstream that changed the Makefile, maybe it broke.
Yes, @DarishZone if you can post the error that would be very useful. Anyway I will also try to compile the core soon and see what is going on. Thanks for reporting!

I just tried installing lr_scummvm on a fresh install and was greeted with the following error:

Could not successfully build lr-scummvm - ScummVM port for libretro
(/home/pi/RetroPie-Setup/tmp/build/lr-scummvm/backends/platform/libretro/build/scummvm_libretro.so not found).

When scrolling a little bit up (I used SSH) I see

collect2: error: Id returned 1 exit status
Makefile:424: recipe for target 'scummvm_libretro.so' failed
make: *** [scummvm_libretro.so] Error 1

and a lot of undefined references above that. The error seems to happen quite at the end, the build process ran for 1h 15 before that...

@jandalf81 There should be a full log file of the installation under ~/RetroPie-Setup/logs - check the most recent one. It would be good if you'd get the file and upload it's contents to pastebin.com to take a look.

jandalf81

@mitu Yeah, sorry. I submitted that post too fast. I'm uploading to pastebin as I type this, will update with a link any minute now

EDIT:
The upload to pastebin failed (it's too large). The whole log (still in the gzipped archive) is here: https://www.dropbox.com/s/zrlw601gzuihsuf/rps_2019-01-11_194137.log.gz?dl=0

@jandalf81 thanks for the log. Indeed the recent commits broke the build for RPI at the final linking stage, hence why it takes a while to compile but fails at the very end. By the looks it seems it needs some flags adjustment in the Makefile.

Unfortunately I won't have time today to fix it, but if you are comfortable using the console, what you can do in the meantime is to force compilation to the last working commit.

With an editor, e.g. nano, open the file $HOME/RetroPie-Setup/scriptmodules/libretrocores/lr-scummvm.sh.

The first function in the file is sources_lr-scummvm(), in there find the line:

gitPullOrClone "$md_build" https://github.com/libretro/scummvm.git

and replace it with this:

gitPullOrClone "$md_build" https://github.com/libretro/scummvm.git master 20d71cd7189ae7fdd453a3041f3103bffabea13e

Afterwards save the changes, exit the editor and try to install again.

When I figure out what is going on will update. Thanks!

DarishZone

Will test that fix in the meanwhile! Thanks

hhromic

@DarishZone thanks! let me know if it worked for you. As soon as I have some time I will take a look to fix the issue properly

DarishZone

@hhromic It works! thanks so much

hhromic

@DarishZone thanks for the feedback. As soon as I figure out the issue I'll report back. Cheers!

Update
I found the problem now, indeed it was an incorrect variable in the updated Makefile. I sent a pull request to upstream to fix it here.
Hopefully it gets merged soon and the build will be fixed instantly. If they take too long, I may provide a temporary patch in the RetroPie script.
Thanks for the report guys!

Thanx! I have to revert the lines to original ones on lr-scummvm.sh or can i leave as edited?

hhromic

@DarishZone now that you built the core successfully, yes you should revert these lines. You can do this now if you wish.

When the PR is accepted, I will also have to slightly update the scriptmodule, so you also will have to update your RetroPie-Setup . I will provide an update here in the forum with more info once things are in place.

Anyway, the new commits in scummvm don't bring any changes to the core itself so you don't need to recompile it again from the build you just did.

Edit to make sure you revert the script properly, run this:

git -C $HOME/RetroPie-Setup checkout scriptmodules/libretrocores/lr-scummvm.sh

Update

The upstream Makefile is now fixed and the lr-scummvm scriptmodule was updated accordingly. You are all encouraged to update your RetroPie-Setup script installation if you want to re-build the core.

Speaking of which, another recent commit was merged that implements a core option to control the Mouse pointer speed when using a mouse device (in contrast to using a gamepad). The new option is named scummvm_mouse_speed and it can be found under the core options in RetroArch. Because it is a libretro option, it can be set on a per-game basis as well.

~~I haven't build the core with this new commit yet, but it should build fine. If you happen to re-compile the core, please let us know how it went.~~ Tested now, it compiles and runs fine :)

Happy point-n-clicking!
