HDX RTME on Ubuntu MS Teams not optimized

[Jens Strohschnitter1709152492]

Did someone get HDX RTME work on Ubuntu ? I've installed Citrix Worspace App 2204 and HDX RTME 2.9.500 on my Ubuntu 20.04 LTS.
But using MS Teams it's showing "Citrix HDX not connected".

 

Checking the installation via /opt/Citrix/ICAClient/util/hdxcheck.sh showes correctly configured HDX optimization:

 

-------------------------------------------------------
-- Checking Microsoft Teams Optimisation Support ... --
-------------------------------------------------------
Success! libc++ is installed. Please ensure libc++(>=9.0) for proper functioning of Optimisation for Microsoft Teams
Success! libunwind is installed. Please ensure libunwind(>=12.0) for proper functioning of Optimisation for Microsoft Teams

 

Has anyone success on using RTME on Linux ?

Found it in another thread, it was a missing libunwind.so.1, what was installed by  libunwind-12 using these commands:

 

 

Look here:

https://docs.citrix.com/en-us/citrix-workspace-app-for-linux/configure-xenapp.html

 

Adding the libunwind-12 library dependency for llvm-12

Starting with the 2111 release, a new dependency called the libunwind-12 library is added for llvm-12. However, by default, it does not exist in the original repository. Install the libunwind-12 library manually in the repository using the following steps:

 

$ wget -O - https://apt.llvm.org/llvm-snapshot.gpg.key|sudo apt-key add

 

$ sudo vi /etc/apt/sources.list

 

Add the following line:

deb http://apt.llvm.org/bionic/ llvm-toolchain-bionic-12 main deb-src http://apt.llvm.org/bionic/ llvm-toolchain-bionic-12 main

 

$ sudo apt-get update 

$ sudo apt-get install libunwind-12

I had the same experience on Debian Bullseye (stable). I find it a little bit strange, that the client requires  a library version which is not included (yet) in many current distributions...

Note that gentoo Linux is affected as well. See here https://bugs.gentoo.org/855374

 

ideally the libunwind dep would be optional if it is only needed to create crash reports, the lib could be dynamically loaded as an optional thing

 

if it is really needed ABI version 8 instead of the old 1 should really be supported, for ubuntu ... and others

ugg, ran into this problem too.  not sure how they're driving the ship over at Citrix... doesn't make sense to say "here's a version for Ubuntu, oh sorry it wont work for you"

[Patrick Herbst1709162474]

i noticed that

/opt/Citrix/ICAClient/lib/libwebrpc.so

is linked against libunwind.so.1

so i figured "what the hell" and did

cd /usr/lib/x86_64-linux-gnu
sudo ln -s libunwind.so.8 libunwind.so.1

and Teams now shows its running optimized.
