No, it should generate an array containung a dump of
the "ansi" termcap entry. Please see the file2c(1)
manpage.

Yes, that's the cause. Why did you do that?
FreeBSD's ncurses port contains a patch so the tgetent()
function (which is used by rtermcap) returns the actual
termcap entry in the buffer. The original ncurses code
(which is terminfo based) doesn't do that.
When you linked rtermcap with the wrong library, you
restored the original behaviour of tgetent(), so the
output of rtermcap was empty, so file2c produced invalid
source.
