when tring to import pyreadr this issue is coming..I think all the functionalities of libiconv is now in libc6. In ubuntu 2204 the libiconv is not there..So what may be the reason for this issue.

versions used ubuntu 22.04 python 3.11 pyreadr 0.5.2

in order to be able to try to reproduce the issue, please indicate how you installed python, please indicate how you installed pyreadr. Although probably that would not solve the issue, try now with the latest version pyreadr 0.5.3. If you installed from pip and you are not using miniconda/miniforge etc, you can try to compile from source, that may solve the issue

The issue is solved once I used the Pyreader wheel file for installing pyreadr.. Eralier I used the Pyreadr tar file for installing the same, that is when the issue occured..

Somehow I was using Ubuntu 24.04 and everything was fine. I updated my environment and then the problem arose. The solution is to statically link iconv in setup.py. However, for other distros (or old ubuntu), linking raises an error. I have not found a good way to detect in which situation we are before hand, for now I have introduced that for ubuntu iconv should be statically linked, but not for other distros.

Earlier I was using the tar file for installing the package so it used to compile the entire package, so later I used the wheel(.whl) file for installing the package and hence it is already compiled my issue is resolved..
