ERROR: displaylink is not available for the 'aarch64' architecture

[Ace]

Hello everyone, I’m pretty new to linux and my machine is the Raspberry Pi 4B which I’m trying to alternatively make a desktop mainly for practicing python programming. I have here a ASUS MB16AC monitor which has displaylink and displayport.

My problem is that when I tried to build displaylink from AUR using pamac, I’m getting an error saying “displaylink is not available for the ‘aarch64’ architecture”.

Building displaylink…
==> ERROR: displaylink is not available for the ‘aarch64’ architecture.

You must’ve noticed that it’s only building the displaylink and that’s because I have a success upon building the evdi driver which has the same error “evdi is not available for the aarch64 architecture” when I’m building it the first time and I fixed it with editing the build file and adding ‘aarch64’ to the list of architectures supported.

Could someone help me with this error? Thank you!

Edit the build file (pkgbuild) in pamac before clicking build.

Find the line similar to:

arch=(i686 x86_64)

and modify it:

arch=(i686 x86_64 aarch64)

And then try building it.
It may or may not successfully build.

Hello, thanks for your response. I’ve tried that fix before I’ve posted this and was no luck.

Here’s the output to the build after the modification.

PKGBUILD: line 50: cd: displaylink-5.3.1.34: No such file or directory

Ok . I thought fake root was not installed but it just that the module seems like it can not be pre-loaded. Looks like there is an issue with the path in line 50 of your PKGBUILD. The directory may be actually named something else.

[Ace]

I think so. Maybe it has to do with fakeroot being not able to open a shared file that it can not locate the directory.

[Darksky]

Most likely an incorrect path on the line 50. Hard for me to see what is going on from here with out building it. Today is Thanksgiving holiday here and I do not have time to do it.

[Ace]

It’s okay, I can wait. But for the meantime, I’ll grasp the flow of the build file. Maybe I can do it manually line by line to see where the error occurs.

cd $srcdir
chmod +x displaylink-driver-$pkgver.run
./displaylink-driver-$pkgver.run --target $pkgname-$pkgver --noexec
cd “$pkgname-$pkgver”

if [ “$CARCH” == “i686” ]; then
ARCH=“x86”
elif [ “$CARCH” == “x86_64” ]; then
ARCH=“x64”
fi

ARCH+="-ubuntu-1604"

echo “Installing DisplayLink Manager $ARCH”

echo “Installing firmware packages”
install -D -m644 *.spkg $COREDIR

echo “Installing license file”
install -D -m644 LICENSE “${pkgdir}/usr/share/licenses/${pkgname}/LICENSE”
}

As per my understanding, I’m changing directory to src and run the code bellow to the terminal and then changing to its directory.

./displaylink-driver-$pkgver.run --target $pkgname-$pkgver --noexec

Am I correct?

[Ace]

Here’s the output of me manually doing this line by line in the terminal.

[Ace]

Now, I found where the error occured. This line of code is not working that’s why there’s no directory to find.

./displaylink-driver-$pkgver.run --target $pkgname-$pkgver --noexec

should I use sudo on this and change ownership to mine and not root? Thanks!

[0n0w1c]

What type of file is it?

Try running:

$ file ./displaylink-driver-$pkgver.run

Does it show ARM aarch64 file?

[Ace]

Here is the output.

file ./displaylink-driver-5.3.1.34.run
./displaylink-driver-5.3.1.34.run: POSIX shell script executable (binary data)

[0n0w1c]

As you are running it as sudo, ownership of the file will not matter.

https://support.displaylink.com/knowledgebase/articles/679060

Shows support for:

./arm* ./x86* and ./x64*

. So in your IF statement, I suggest trying:

ARCH="arm".

Edit: And if that does not work, try ARCH=“arm64”

[0n0w1c]

I assume arm-linux-gnueabihf is a directory, similar in contents as the two ubuntu directories. I then further assume the binary driver is in there… but I fear it is armhf and not arm64.

[Darksky]

This is not going to happen on arm64. The only directory there for arm is 32bit.

[Ace]

@0n0w1c
I changed my IF statement and added arm and arm64, and I got this error.

I think this one is crucial, because there’s no ‘arm-ubuntu-1604’ or ‘arm64-ubuntu-1604’ directory.

ARCH+="-ubuntu-1604"

Inside the path file dislaylink-$pkgver:

[aces@aces-desktop src]$ cd displaylink-5.3.1.34/
[aces@aces-desktop displaylink-5.3.1.34]$ ls
3rd_party_licences.txt    ella-dock-release.spkg        LICENSE                  x64-ubuntu-1604
arm-linux-gnueabihf       evdi.tar.gz                   ridge-dock-release.spkg  x86-ubuntu-1604
displaylink-installer.sh  firefly-monitor-release.spkg  udev-installer.sh

Therefore displaylink is not available in arm64 machines? or will it still run even if it’s for arm 32bit on arm64 machines?

No matter what you do it is not going to work. The arm directory has a pre-compiled 32bit lib it wants to install to your system.

And I have no clue why they are furnishing the 32 bit libusb since libusb is in the repo.

And the DisplayLinkManager in the same directory is a 32 bit executable binary.
