[Buildroot] [PATCH] lftp: new package.

["Arnaud Rébillout" <rebillout@syscom.ch>]

Hi Thomas,

thanks for your comments, I'll send a second revision with everything fixed.

Here is a piece of the m4 file which describes the macro 
(lftp-4.4.10/m4/lftp.m4, line 246):

> AC_DEFINE(HAVE_POSIX_FALLOCATE, 1, [Define if you have a working 
> posix_fallocate()])
> AC_DEFUN([LFTP_POSIX_FALLOCATE_CHECK],[
>    dnl * Old glibcs have broken posix_fallocate(). Make sure not to 
> use it.
>    dnl * It may also be broken in AIX.

In order to test that, the configure script compiles and runs a piece of 
C code.

There's two problems with that.

First, the code won't compile because uClibc doesn't define 
posix_fallocate. To solve that, we can fix the m4 macro with a #define.
It's quite easy, though I don't know exactly how to do it properly.

But after that comes the second problem: the test is supposed to run 
this piece of code. How are we supposed to run cross-compiled code on 
the host ?
I can imagine it's a typical problem, but I don't know how it's supposed 
to be handled.


Regards,
Arnaud.
