I want to run a program which requires HDF5 1.8.21 (old ver). Now, I downloaded and compiled HDF5 1.8.21 in a separate folder (/opt/hdf5/hdf5-1.8.21/hdf5/bin). But because my desktop already has HDF5 Version 1.10.1 (new ver), which I can not remove, as it will break some other packages. What is the best way to overcome this problem? Is there a way by which I can safely set a path or environment such that while the above mentioned program is running, older version of HDF is used? Thanks.

The easiest solution:

PATH=/opt/hdf5/hdf5-1.8.21/hdf5/bin:$PATH <your-special-case-program>

Make a shell script or a .desktop file easy launch.

  • Thanks for the suggestion. I tried this but it is not working. It seems that the program I am trying to run calls another program(s)/script(s). Can you please tell me, if I set the PATH as suggested above, should it still work? – Aman_X Oct 16 '19 at 8:51
  • @Aman_X, Could you edit question and add output of echo $PATH and the output when you tried the command I gave in my answer. – user.dz Oct 16 '19 at 9:09
  • I have edited my question. The output after using the command you gave does not give an error, but the output is same as before. In other words, my program does not detect the new PATH. – Aman_X Oct 16 '19 at 9:24
  • @Aman_X, Could you show me what you see when you run your program? Are you compiling and testing a program from source ? – user.dz Oct 16 '19 at 9:30
