Request to wrap wine-i386 sxs.so

[WheezyE]

Hello. I'm trying to get someone's hardware power relay (DRA-70's "PTT" switch) working in box86 with a program called soundmodem and I believe we might be running into a roadblock with hid.so not being wrapped yet. WheezyE/Winelink#10

mkdir soundmodem && cd soundmodem
wget http://uz7.ho.ua/modem_beta/ptt-dll.zip 
wget http://uz7.ho.ua/modem_beta/soundmodem114.zip #EDIT: Updated link
7z x soundmodem114.zip
7z x ptt-dll.zip
BOX86_NOBANNER=1 winetricks -q vb6run # wine-mono / dotnet are not required
wine soundmodem.exe

I suspect that PTT.DLL might be the component that calls hid.dll. If that's the case, we might also be able to fix VARA HF/FM (Winlink) compatability with the DRA-70 with hid.so wrapping.

Here's a box86_log1 of soundmodem with PTT.DLL

• Note: I took out all of wine's X11 warnings to make the log easier to read
• Box86 with Dynarec v0.2.5 ed8e01e built on Dec 10 2021 23:45:16 (this version works best with VARA HF/FM for TCP - I'll post another issue later when I find which commit breaks VARA's TCP)
• Wine-devel-7.1

I wish I could test this more with winecfg Library overrides, but I unfortunately don't own a DRA-70 myself. I'll also ask mhnadler to jump in on this thread in case we need more logging.

[WheezyE]

Omg 🤦‍♂️ hid is available from winetricks. Please disregard this.

[WheezyE]

I've been experimenting with MS Process Explorer on Windows with soundmodem.exe and noticed that sxs.dll is one of the processes that is run when PTT.DLL is present for this program. I think this one might be needed too.

On Pi4, when I install hid.dll with BOX86_NOBANNER=1 winetricks hid, the BOX86_LOG=1 is the same as above (just without hid.so). I also tried installing vcrun2012 with winetricks but that didn't get rid of sxs.so in the log. I also reinstalled and tried vcrun2019 with winetricks, but no luck

[ptitSeb]

Is this fixed with latest box86?

[WheezyE]

I'm not entirely sure if this is fixed yet (since I don't personally have the "DRA board" hardware to test with), but I'll check in with some people to see if it's working for them yet.

I'm currently working on soldering together a mockup hardware thing to pretend to be a DRA board to do more testing, so I might make a new issue in the future if I get a better testing environment.

This at least is very cool: No more `Error loading needed lib` errors

[SpudGunMan]

just tested with latest scripts and DRA did not function with vara

[ptitSeb]

can it be a box86rc issue?

[SpudGunMan]

Possibly I haven't dug deep, I assumed it was hid i/o related at the moment

[WheezyE]

Kelly, thank you for testing this. I’m still not sure if it’s a bug in wine or in box86. Would you be able to see if your DRA board works on x86 Linux? The Winelink script should install on Ubuntu and Debian. An Oracle VM or VM Ware linux install might be helpful to use as a testing tool for that. Eric

Also thank you, Seb. Sorry for the radio silence. I’ll come back to this end of January pretty soon. I’ve been taking some time off and am getting married in a few days 🙂

Yea I will try and get a test on x86 platform.

Compiled newest box86 just now same problem issue with no device to DLL

[SpudGunMan]

Same issues on x86 vm, no RA board. No matching HID found I assume

[WheezyE]

Nice job, Kelly. We might assume this is a wine issue then, instead of a box86 issue. I suppose the winehq forums or WineHQ BugZilla would be the next place to check.
