I have this code that I have run many times within the past few months without problems. However, today I get an error while running the program:
/home/gamma/root/bin/root.exe: relocation error: /home/gamma/data/data2/./spectrum_c.so: undefined symbol: gzopen
I know that someone else has been working on the computer between the time that the program worked and now, so it is possible that they changed some of the links. I have not changed the program at all between the last time it worked and now. Also, if I try to reload the program, I get the following error:
dlopen error: /home/gamma/data/./spectrum_c.so: undefined symbol: gzopen
Load Error: Failed to load Dynamic link library /home/gamma/data/./spectrum_c.so
but root still creates the .so file despite the errors. I really have no idea where to even start to fix this problem. I would appreciate it if someone could tell me what these errors mean.
