Hi again,
I show more about the error when configuring.
this is the message I get when running the "./configure" command.
checking for readline... no
configure: error: readline library not found
If you have readline already installed, see config.log for details on the
failure. It is possible the compiler isn't looking in the proper directory.
Use --without-readline to disable readline support.
I don't know about the headers.
Thanks for your attention
