Re: Help on installation - Can't find function `int isinf(...)'

[Mats Bengtsson]

You did use the gcc compiler, did you?

I don't have access to Solaris myself, but checked in Google 
and found some answers indicating that isinf is not standardized
enough to appear on all systems, for example Solaris.

According to an old FAQ entry, the following workaround 
can be used

    #include <ieeefp.h>

    int isinf(double x) { return !finite(x) && x==x; }

configure does indeed check if isinf is available and 
defines a HAVE_ISINF preprocessor macro. If you 
manage to solve the problem in some appropriate 
lily/include/*.hh file please send a patch so other 
Solaris users can avoid the same problem.
