I am trying to run a file compiled in c and I get the following error message:
"error while loading Shared Libraries: libpq.so. 5: Wrong ELF class: ELFCLAS64"
I did a search and identified that this type of error is due to x64 and x86 libraries, but did not find in any corner how to solve this problem.
I already installed the postgresql and libpq5 packages but it didn’t help.
