ubuntu 23: radian fails to start

[fpcarv]

Hi!

After installing successfully the radian package it fails to start saying that it can't find libR.so ...

Traceback (most recent call last): File "/home/francis/.local/bin/radian", line 8, in sys.exit(main()) ^^^^^^ File "/home/francis/.local/lib/python3.11/site-packages/radian/app.py", line 121, in main RadianApplication(r_home, ver=version).run(options, cleanup=cleanup) File "/home/francis/.local/lib/python3.11/site-packages/radian/app.py", line 218, in run rchitect.init(args=args, register_signal_handlers=True) File "/usr/local/lib/python3.11/dist-packages/rchitect/setup.py", line 49, in init raise Exception(load_lib_error()) Exception: Cannot load shared library: /usr/local/lib/R/lib/libR.so: undefined symbol: u_versionToString_70

However libR.so is there, at the place radian says it's looking for it:

$ ls -l /usr/local/lib/R/lib/libR.so -rwxr-xr-x 1 root root 13267328 fev 4 2023 /usr/local/lib/R/lib/libR.so

Am I doing something wrong?

Thanks for any help!

It is a rpath issue of your libR. For some reasons, radian seems to fail to set the correct ldpaths to discover the dependencies needed. Could you show the results of ldd libR.so?
