[Axiom-developer] Is package SIGNEF missing?

[David MENTRE]

Hello,

While preparing screenshots for Axiom web page, I tried Tim's
integral-longer-than-the-screen but it failed on my home compiled Axiom:

(1) -> integrate(1/(x**3 * (a+b*x)**(1/3)),x)
 
   >> System error:
   Cannot open the file 
/home/david/pub/axiom-libre/axiom-dm/axiom-i386/mnt/linux/algebra/SIGNEF.o.

protected-symbol-warn called with (NIL)

However, it seems to work for a more simpler integral:


(1) -> integrate(1/(x**2),x)

          1
   (1)  - -
          x
                                          Type: Union(Expression Integer,...)

Or even more complicated one:

(1) -> integrate(x**(1/3),x)

          3+-+
        3x\|x
   (1)  ------
           4
                                          Type: Union(Expression Integer,...)
(2) -> integrate(1/(x**(1/3)),x)

         3+-+2
        3\|x
   (2)  ------
           2
                                          Type: Union(Expression Integer,...)


Is the failure only in my version or is it a new axiom bug?

Yours,
d.
