Did you move the code to a different file path after running setup.sh?

That is the most likely cause of this error: the file path to the binary data files is stored at compile time. If you move the code, you should run make clean and re-run setup.sh to ensure all the C code is recompiled.

[rkhan2022]

Thanks for your valuable suggestion. I am going to reinstall both star charter and ephemeris-compute-430 again directly under my home folder, after that I will report you about the development.

No I have not move the directory anywhere.
Now I have tried as follows and gets error1
