I've been trying to compile on fedora 24 and I'm running into this bug issue:

src/auto/config.log

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.69.  Invocation command line was

  $ auto/configure --enable-multibyte --enable-python --enable-rubyinterp --enable-luainterp --with-tlib --srcdir=. --cache-file=auto/config.cache

It seems the error is in src/auto/configure

What happened to make you close this issue? Did it disappear on "make reconfig" or similar? Or was it something else?

For some reason doing configure with --enable-rubyinterp was causing the issue, as soon as I dropped that flag I was able to configure and install correctly. I tried doing configure using --with-tlib as well and that did not help.

./configure --enable-fail-if-missing     --enable-luainterp --with-luajit     --enable-perlinterp     --enable-pythoninterp     --enable-python3interp     --enable-rubyinterp     --enable-tclinterp     --enable-multibyte     --enable-fontset
....
checking for tgetent in -lcurses... no
no terminal library found
checking for tgetent()... configure: error: NOT FOUND!
      You need to install a terminal library; for example ncurses.
      Or specify the name of the library with --with-tlib.

I do indeed have ncurses installed:

Are you install ncurses-devel?

$ sudo dnf install ncurses-devel

I've just installed gcc 6 on Ubuntu 16.04, and built vim using --enable-rubyinterp with no trouble. My config.log contains the errors you report; it continues:

configure:2993: checking whether the C compiler works

I conclude that those errors are not your problem. You may have concluded the same, since --enable-rubyinterp has nothing to do with that part of configure's processing.

Hi everyone!
If someone hits the same problem, the solution is to add:

LDFLAGS="$LDFLAGS -fPIC"

to 'configure' command line invocation. It seems something (probably a tool from autotools - autoconf) does not provide -fPIC into LDFLAGS in Fedora. Because when I manually compile the code (although I need to add <term.h> as include) with -lncurses, it compiles correctly. So either gcc/ld uses -fPIC without my notice, when I use gcc manually, or autoconf does not set it....
