Apple2e: AppleWin Libretro

@Retrodade as far as i now its still working,
when you start the game you need to press a and then launch it with Verbose log

https://retropie.org.uk/docs/Runcommand/#launch-with-verbose-logging

that way it will make a log file that you can post here and we can see what is going on

also what are you running it on

You are missing a dependency.
Try to install it manually from the cli and see if it works :

sudo apt install libslirp-dev

Or add it to the modulescript in lr-applewin.sh in the function depends and reinstall the core again.

ExarKunIv

@Folly its odd that its missing
the script builds it from source

gitPullOrClone $md_build/../libslirp https://gitlab.freedesktop.org/slirp/libslirp.git

UPDATE

yes something it broken, not sure where, yet
the script does build libslirp from source and does install it
i can do a file search and its there, libslirp.so.0

i dont know why its not being found maybe @Lolonois can shed some light on this one
im trying a older commit to see if the dev changed something

Retrodade

@ExarKunIv ok great i did try the 2 methods above and it wouldn't add it

first I tried this way.

pi@retropie:~ $ sudo apt install libslirp-dev
Reading package lists... Done

Building dependency tree

Reading state information... Done

E: Unable to locate package libslirp-dev

then I tried adding it in the sh

As I mentioned already in another thread: With this outdated version you are on your own (v1.8.5 was added at 2020-04-17 to RetroPie).

Currently RetroPie is on retroarch v1.16.0, I tested lr-applewin with retroarch v1.12 onwards.

Lolonois

@Folly on RetroPie on RaspiOS Buster this lib is not available as package. There is a reason I added the source build ;-) Please avoid hinting less experienced users in the wrong direction.

Lolonois

@ExarKunIv I'd like to challenge that the scriptmodule is wrong/outdated.

I had no luck to reproduce the missing libslirp dependency.

I have tested with RP 4.8.6 (commit 656a478e):

Explicitly deleted the libslirp installation from /usr/local/lib/arm-linux-gnueabihf/ and /usr/local/lib/arm-linux-gnueabihf/pkgconfig
I have taken the scriptmodule as in the latest revision in the gist
I tried with the dialog basesd retropie-setup.sh and as well with retropie-packages.sh lr-applewin

No issues.

Can you provide a build log of lr-applewin from ~/RetroPie-Setup/logs/rps...gz via pastebin or similar?

Do you have the *.so files and symlinks in /usr/local/lib/arm-linux-gnueabihf/ after the scriptmodule did run?

Does ldd find libslirp? Issue: ldd /opt/retropie/libretrocores/lr-applewin/applewin_libretro.so | grep slirp, it should give you one match.

If there is no match. What is the content of the file/is this file below present?

$ cat /etc/ld.so.conf.d/arm-linux-gnueabihf.conf 
# Multiarch support
/usr/local/lib/arm-linux-gnueabihf   # <--- this must be there
/lib/arm-linux-gnueabihf
/usr/lib/arm-linux-gnueabihf

If it (=the marked line above) is there, do update the library dependency cache with sudo ldconfig -v | grep slirp. You should see a line like

[...]
	libslirp.so.0 -> libslirp.so.0.4.0
[...]

Then check again: Does ldd find libslirp? (see above)

With the information I had it was the most obvious hint.

I know it installed that just fine for me on my test setup. I'll have to check the symlinks

But it end up giving the same error as reteodade

I already have it working on my main system. But that was done awhile ago. But I'm going to compare that with my test setup on Monday

I find it odd that a few other people are having issues. But you aren't. And I have 1 system that's fine and 1 that's not working

Retrodade

@ExarKunIv does this mean I have possible hope getting it running on our pi4?
thanks for looking at our error log btw

ExarKunIv

@Lolonois got to love linux.
so i did a clean load to start all my comparing and what not.
and now it works just fine.
even though on friday even with a fresh and updated RP it would not start a game

as you said. you need to update the RP script and update everything.

i did a fresh load and with out updating it didn't work ( as you said it wouldn't) then i updated everything to the same commit that you did and it worked just fine after that. No error

so i did a new card and fresh image
this time i just updated retroarch, that didn't work. (was not expecting it too)
did a full update and like before it now works

So i agree, it is working as it is designed, why it didnt work before for me. i will never know

@Retrodade sorry, as

Currently RetroPie is on retroarch v1.16.0, I tested lr-applewin with retroarch v1.12 onwards.

theres not much I and @Lolonois can do.

the only thing i can say if you want to get applewin to work. you will have to update your system.
as i said above, updating retroarch to the latest which it 1.16.0 will not make it work. you need to the main Retropuie system files also
