Problem with ACLIC linking friend functions under WinXP + root 4.04.02

Hello ROOTERs,

I am trying to use ACLIC on a macro that uses a class (TQuaternion) that I previously loaded (in a library called libMath, see attached session) Methods of the class are correctly linked (for exemple ACLIC does not complain about Tquaternion::operator+(double))

But for friend function (like Tquaternion operator+(double, Tquaternion&) ) ACLIC linker Complains about not finding the corresponding function.

When compiling the macro under Visual I have not problem When interpreting the macro I have no problem (see attached session) Finally if I comment the line " q2 = a + q; " ACLIC also works

Does somebody has a hint of what I might be doing wrong ?


Compiled for win32.
