I am trying to install readline using the command "python setup.py install" by navigating to the directory where i untarred readline 6.2.4.1. ncurses-6.0 is currently installed in the server. I have tried recompiling with -fPIC but that also doesnt seem to solve the problem

Command: sudo CFLAGS="-fPIC" python setup.py install

Error Log:

The issue is not -fPIC within the library you are building but instead on how the libncurses.a was build (without -fPIC). Either prefer libncurses.so or rebuild libncurses.a with -fPIC – malat
How do i rebuild libncurses.a? should i configure ncurses with --shared-enabled which should handle this indirectly? – prabesh

I tried the following and it worked.

Navigate to ncurses directory that contains configure and run the following ./configure --with-shared --without-debug make make install

Then install readline again. The error desappeared. The module was successfully installed.
