[CLAM] two problems in GNULinux version

[Vicen]

Hi all again! I hope I'm subscribed to the list. In the CLAM subscribers 
web appears my name (vicen.gomez at iua.upf.es)  :)

Only two little questions, for the public version:

I've tried to compile all the Tutorial examples of the 
/CLAM/examples/Tutorial directory:

All work well except the fourth. The compiler found an error in the line 
accessing to an attribute of an Spectrum object:

        Array<Complex<TData> > &cplx = spec.GetComplexArray();

The error is:

.../UserTutorial4.cxx:48: non-template type `Complex' used as a template
.../UserTutorial4.cxx:48: ANSI C++ forbids declaration `' with no type
.../UserTutorial4.cxx:48: conversion from 
`CLAM::Array<CLAM::ComplexTmpl<double> >' to non-scalar type 
`CLAM::Array<int>' requested
.../UserTutorial4.cxx:48: cannot initialize `CLAM::Array<int> &' from 
`CLAM::Array<CLAM::ComplexTmpl<double> >'
.../UserTutorial4.cxx:53: request for member `SetReal' in 
`(+cplx)->CLAM::Array<int>::operator []((&i))', which is of 
non-aggregate type `int'
.../UserTutorial4.cxx:54: request for member `SetImag' in 
`(+cplx)->CLAM::Array<int>::operator []((&i))', which is of 
non-aggregate type `int'

Error 1
make[1]: Leaving directory `/home/vicen/clam/CLAM/examples/Tutorial'
make: *** [UserTutorial4] Error 2


On the other hand, when I tried to compile some other programs I've this 
linker error:

I've installed all fltk packages I've seen via apt-get install, before 
checking out all the things. They are:

fltk-doc - Documentation for the Fast Light Toolkit
libfltk1 - The Fast Light Toolkit, a GUI toolkit inspired by libForms
libfltk1-dbg - The Fast Light Toolkit, and the Fluid user interface designer
libfltk1-dev - The Fast Light Toolkit, and the Fluid user interface designer
libfltk1-example - The Fast Light Toolkit, and the Fluid user interface 
designer

Maybe I missed some dependence or I've done anything incorrect.... 
(Note: The AnalisysSynthesis example compiled well, though).


    Thank you,
