Memory!

[Francisco Frutos <frutos at linmpi dot mpg dot de>]

Hi Brian!

I'm using the Sun cc and not gcc. Because of the XForms, I cannot compile
my program with gcc and if I try it, then I get a lot of error messages
and no executable. How kann I check memory accesses without checkergcc?

I'm using gsl_multiroot subroutines in the following form:

F.f = &function; 
F.n = 2;
F.params = 0; 

and then I got by compiling with cc such warnings:

./rootfinder.c", line 175: warning: assignment type mismatch:
        pointer to function(pointer to const struct gsl_vector_struct
{uint size, uint stride, pointer to double data, pointer to st... "="
pointer to function(pointer to struct gsl_vector_struct {uint size, uint
stride, pointer to double data, pointer to struct g...

I don't know if that could create memory problems!

Thanks in advance!

Greetings from katlenburg-Lindau!
