R package kernlab installation issue

Question

I am facing issues while installing the kernlab R package on CentOS using the following command:

install.packages("/home/R_Libraries/kernlab_0.9-20.tar.gz", repos = NULL, type="source")

I get the following error:

Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared object     '/opt/vertica/R/library/kernlab/libs/kernlab.so':
  libgfortran.so.3: wrong ELF class: ELFCLASS32

gfortran is installed as confirmed by the following command:

ldconfig -v|grep fortran

libgfortran.so.1 -> libgfortran.so.1.0.0

Can someone help with fixing this issue?

Answer 1

This error:

 libgfortran.so.3: wrong ELF class: ELFCLASS32

means that you've tried to load 32-bit libgfortran into a 64-bit program.

Unfortunately you didn't tell us anything that would allow us to help you. Not even where this libgfortran is coming from.

You should make sure that a 64-bit libgfortran is installed in the system location, and the above error would go away.
