[ADOL-C] fmax conflict with c++ gcc 4.4.6

[Antoine De Blois]

Hi everyone,

We recently upgraded our linux cluster from redhat rhel5 to rhel6, which comes with the upgrade gcc 4.4.6. The latter has an fmax function defined in the <cmath>, which results in a conflict with the ADOL-C implementation.

Has anyone came up with a simple fix for that? I tried to define a new namespace, as follows, without success:

namespace AD
{
template <typename ADdouble1, typename ADdouble2>
inline adouble fmax(ADdouble1 a, ADdouble2 b)
{
   return fmax(a,b);
}
}

But when I try to use it, the function get caught into the
locint StoreManagerLocintBlock::next_loc()

of tape_handling.cpp

and I do not understand why.

Thank you for your time and efforts,
Antoine
