Re: USE_READLINE

[RLake@...]

Not that I know anything about the cygwin environment, but don't you need
to add -lreadline somewhere in the link options?

Hi all !

I've tried both solutions without success. I have noticed that
#ifdef USE_READLINE
#include <readline/readline.h>
#include <readline/history.h> ...
has already been added to lua.c. So it should have worked out of the box,
right?
The error messages are reported below.

So the problem is with cygwin/gcc. Does anybody know how to configure gcc
to get
everything working in the cygwin environment?

Thanks again!

The failure messages I got were:
