I reinstalled ubuntu server 20 on my pi and made the setup steps again. Now it is working (even without a venv). Thank you for your help. I think i missed something in my first try but i don't know what.   Best regards, Benni ... View more

We are already using a venv (in the QEMU setup) with no success. I also tried it on the Raspberry Pi with no success. What we did: Setup a Raspberry Pi with Ubuntu Desktop 20 (Arm64) Manually creating all the scrtips for setting up the development environment from here: install-snapcraft.sh install-snapcraft.sh install-deb.sh (There is no install-deb configuration in the aarch64 setup, so we used it from the amd64 setup. Installing all required packages listed with apt here. Running the createt scripts in step 2 Creating a venv as described here Installing all depedencies including the ctrlx-datalayer Starting the venv with the command    source venv/bin/activate   Running the python interpreter with   python3​   Trying to import the ctrlx-datalayer with   import ctrlxdatalayer​    Getting the error   Python 3.9.13 (main, May 23 2022, 21:57:12) [GCC 11.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import ctrlxdatalayer System architecture: aarch64 Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python3.9/dist-packages/ctrlxdatalayer/__init__.py", line 7, in <module> from ctrlxdatalayer import client, converter, factory, provider, provider_node, \ File "/usr/local/lib/python3.9/dist-packages/ctrlxdatalayer/client.py", line 9, in <module> import ctrlxdatalayer.clib File "/usr/local/lib/python3.9/dist-packages/ctrlxdatalayer/clib.py", line 14, in <module> libcomm_datalayer = ctypes.CDLL("libcomm_datalayer.so") File "/usr/lib/python3.9/ctypes/__init__.py", line 374, in __init__ self._handle = _dlopen(self._name, mode) OSError: libcrypto.so.1.1: cannot open shared object file: No such file or directory​   I also checked teh GLIBCXX.   strings /usr/lib/aarch64-linux-gnu/libstdc++.so.6 | grep GLIBCXX   with the response   GLIBCXX_3.4 GLIBCXX_3.4.1 GLIBCXX_3.4.2 GLIBCXX_3.4.3 GLIBCXX_3.4.4 GLIBCXX_3.4.5 GLIBCXX_3.4.6 GLIBCXX_3.4.7 GLIBCXX_3.4.8 GLIBCXX_3.4.9 GLIBCXX_3.4.10 GLIBCXX_3.4.11 GLIBCXX_3.4.12 GLIBCXX_3.4.13 GLIBCXX_3.4.14 GLIBCXX_3.4.15 GLIBCXX_3.4.16 GLIBCXX_3.4.17 GLIBCXX_3.4.18 GLIBCXX_3.4.19 GLIBCXX_3.4.20 GLIBCXX_3.4.21 GLIBCXX_3.4.22 GLIBCXX_3.4.23 GLIBCXX_3.4.24 GLIBCXX_3.4.25 GLIBCXX_3.4.26 GLIBCXX_3.4.27 GLIBCXX_3.4.28 GLIBCXX_3.4.29 GLIBCXX_3.4.30 GLIBCXX_DEBUG_MESSAGE_LENGTH     I am using a Arm64 architecture so the path to libstdc++.so.6 is differnt.  I managed to get it run on my QEMU environment with amd64 architecture.I missed to step to install the datalayer dev here. Is arm64 not supported for the datalayer in the development environment? Best regards, Benni ... View more

Hey, thank you for your fast response. The error occurs when we try to run our app in the development environment. Thank you for your hints. We started to setup a dev environment manually because we don't use Windows computers and so the ctrlX Works software is not working for us. First we tried a solution by using a Raspberry Pi with Ubuntu 20 (Arm64) for development and for building our snaps. Everything worked fine until we wanted to include the datalayer in our application.  Because that didn't work we setup a QEMU environment with the scripts provided in the ctrlx automation sdk folder but with the same result (like we shown in the error code snippets above) Best regards,  Benni ...
