Release 59348 and above not fully backward compatible (GLibC)

[YoannVarquet]

Hi,

I installed an older version through pip3 a one of my system, and it works great, (awesome job!), however, since New API, 2.0, the DLL are not compatible with my system. I use Nvidia with an old JetPack and can't move from it, and I get an GlibC imcompatibility issue. Having a lot of things running on it, I cannot just afford to upgrade GlibC, way too much hassle.

Current GlibC is 2.27.

I guess I'll be installing Yoctopuce from source, but it would be nice to have it backwards compatible.

Best wishes Y.

This issue should be fixed now. Could you validate that it solve your issue?

I am experiencing this issue on Ubuntu 20.04 and Ubuntu 18.04 with yoctopuce 2.0.61039. It is working fine on Ubuntu 22.04

  File "/home/user/project/venv/lib/python3.9/site-packages/yoctopuce/yocto_api.py", line 1122, in yloadYapiCDLL

During handling of the above exception, another exception occurred:

We have been able to reproduce your issue. We should have a fix very soon.

That's great news. Thanks for the prompt response!

For others running into similar issues, here's how I fixed it in the meantime:

1. Download the YoctoLib.cpp source: https://www.yoctopuce.com/FR/downloads/YoctoLib.cpp.61199.zip
2. Extract it on your machine.
3. Because I am on Linux, I had to run sudo apt-get install libusb-1.0-0-dev
4. Then run build.bat or build.sh depending on your platform.
5. Wait for the compiling to be done.
6. Now copy "libyapi.so.1.0.1", rename to "libyapi-amd64.so" and replace the incorrect shared library with it (in my case it was in: /home/user/project/venv/lib/python3.9/site-packages/yoctopuce/cdll/libyapi-amd64.so On other platforms, the names and paths will be different.

After that all worked as expected!

Could you validate that the following binaries are working on your computer: https://www.yoctopuce.com/FR/downloads/YoctoLib.pythonV2.61305.zip

I can confirm this is working on Ubuntu 20.04 after updating libyapi-amd64.so

[srinsoz]

Ok. We have just officially release the fix.
