Daphne install on ubuntu 18.04 x86_64

CaptainDatabase

I've been trying to recreate these modifications to install daphne on my Atomic Pi. I got the emulator to install, but it unfortunately still doesn't show the roms in emulation station. If anyone knows what might cause this, I'd appreciate any advice you can share!

Update: I've gotten emulation station to show roms, but the emulator is still giving me an error when trying to run saying that vldp2 is not found.

MrCoolSpan

sorry about the no response i have a lot to do
now i well try this on my new ubuntu 20.4 x64 system

CaptainDatabase

Sorry, forgot to update. Manually installing vldp2 fixed the issue. I'm not sure why the lines in the script didn't work properly, but doing it myself worked fine. 🤷‍♂️

@mrcoolspan I've installed Ubunto 20.4 and the latest updates and RetroPie from mrcoolspan .git
The setup script fails to execute and logs a dependency i cannot resolve:

E: Unable to locate package python-pyudev
Unable to install packages required by /home/arcade/RetroPie-Setup/retropie_packages.sh - Could not install package(s): python-pyudev.

@heavyholyman It's not part of the official Ubuntu repositories after 18.04 anymore:

https://packages.ubuntu.com/search?keywords=python-pyudev&suite=default&section=all&arch=any&searchon=names

Until @mrcoolspan updates the script, you could try to download and install the 18.04 version. Choose a mirror in your region, download the file, and try to install it with this command:

sudo dpkg -i python-pyudev_0.21.0-1_all.deb

I didn't test this, though. There might be other packages missing or at the wrong (newer) version in 20.04.

@clyde Thanks for the advice! It was tedious, but i finally got Daphne working properly on Ubuntu 20.04.2. To install from MrCoolSpan's git, i installed python-pyudev as you suggested. However, it first needed python-six, which i tried to install using 'sudo apt-get install python-six'. That also threw an error, but things improved after 'sudo apt --fix-broken install'. After that command, i was able to install python-six, then python-pyudev.

With the pre-reqs taken care of, i was then able to run retropie-setup and install daphne. Games launched from EmulationStation, but i prefer Attract-Mode front-end. Attract would not launch any games, and displayed an error that it could not load VLDP dynamic library. That was resolved by copying libvldp2.so to the /lib/ directory. 'sudo cp /opt/retropie/emulators/daphne/libvldp2.so /lib'

All is working now, but i sure wish daphne simply worked 'out of the box' instead of requiring the extra steps!

Clyde

@heavyholyman Good to hear that it works. As a little word of advice, I would have linked the libvldp2.so to /lib rather than copying it:

sudo ln -f -s /opt/retropie/emulators/daphne/libvldp2.so /lib/libvldp2.so

The -f option (force) will replace any existing file or link with the same name in the destination with the new link. The -s option will create a so-called symbolic link (symlink) or soft link that shows you its destination when you list it with the ls command.

ls -l /lib/libvldp2.so

(Both l are lowercase L and not ones.)

This way, you'll always know where this file in one of your system's directories came from. But this is only a measure for a tidy system and shouldn't make any operational difference. 🧐

MrCoolSpan

@clyde I have fix that ;)
just download from my git

New issue. Can't get Daphne to compile because it needs bits/predefs.h to be available. I believe it's missing from the latest version of Ubuntu.

I'm using Ubuntu 22.04.1 LTS 64-bit

mitu

@VintageVolts Please open a separate topic - you seem to have a different issue than the original poster (which was using Ubuntu 18.04).

VintageVolts

@mitu

I was using the replacement install script that the OP put out in his first post. The point I was making is that his script is having issues in a newer version of Ubuntu.

Even heavyholyman in this thread is referring to Ubuntu 20.04.2 with the conversation continuing on.

Mine just seemed to be an issue regarding running the OP's new install script, regardless of Ubuntu version.

mitu

@VintageVolts Maybe try hypseus instead of the old Daphne code, it's maintained and works for PC systems also.

VintageVolts

@mitu

Tried that already. Doesn't compile in Ubuntu 22 64-bit either. That's why I decided to see if MrCoolSpan had an answer for Daphne and Ubuntu 22 first, since its issue was already on the table, so to speak.

Hm, that's an issue - is the same error you get on the original Daphne sources or it's during the configuration phase (cmake error) ?

VintageVolts

@mitu

It's the same error.

mitu

@VintageVolts You may be missing some package dependencies.
Why are you trying to build the package manually ? You can install hypseus from RetroPie-Setup - like any other emulators - and there's no error when doing so (tested on Ubuntu 22.04).

@mitu

It's the same error.

So predefs.h is one of the headers needed to compile against 32 bit binaries in a 64 bit system. It's usually present in libc6-dev-i386 package.

I suspect you are missing the step to enable 32-bit Arch in 22.04 - tutorialforlinux link.

sudo dpkg --add-architecture i386

sudo apt install libc6-dev:i386 libc6:i386 libstdc++6:i386 
libncurses5:i386 zlib1g:i386 etc.....

But as @mitu states use RetroPie-Setup
