Octave-Forge with Linux Fedora 3

[Carine Simon]

Hi,

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
/var/cache/man/cat3/signbit.3.bz2
/usr/share/man/man3/signbit.3.gz
/usr/share/man/man3p/signbit.3p.gz
Therefore, I've been looking for a solution on the web, and I've found a patch on http://bugzilla.ximian.com/show_bug.cgi?id=51315. It was said to add the following in configure.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);
], [
AC_MSG_RESULT(yes)
])
As I didn't know in which configure.in to put it (I am a beginner ;-)), I've added it to all of them, i.e.
/usr/share/pvm3/src/regex/configure.in
/usr/share/doc/ncurses-devel-5.4/test/configure.in
/root/tmp/octave-forge-2004.11.16/nonfree/gpc/configure.in

However, when I run autoconf on configure.in 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?

Thanks,
Carine.
