I am trying to install the octave-forge package (version 2004.11.16) in order to have some useful functions on the top of
octave (version 2.1.57-7 (i686-pc-linux-gnu)) on my Fedora 3 (Red Hat) PC.
I've got some troubles, the main one seeming to come from the inexistence of the signbit function. Indeed when I do a find on my computer, I can only find
Therefore, I've been looking for a solution on the web, and I've found a patch on It was said to add the following in
dnl *** Check for signbit ***
dnl *************************
AC_MSG_CHECKING(for signbit)
- AC_TRY_COMPILE([#include <math.h>], [
+ AC_TRY_LINK([#include <math.h>], [
int s = signbit(1.0);
], [
As I didn't know in which to put it (I am a beginner ;-)), I've added it to all of them, i.e.

However, when I run autoconf on files with this patch, I get the following error:
NONE:0: /usr/bin/m4: ERROR: EOF in string
autom4te: /usr/bin/m4 failed with exit status: 1

And there, I get stucked.
Any idea around to help me and to try to FINALLY make it work?
