Hi,

in my developement I use to include some tests that check that a header file 
compiles. Other boost developers do the same. How this is done now?

We write a .cpp file including the  header file

// check_header1_compiles.cpp
#include <boost/header1.hpp>

and add it to the list of compile test

test-suite LIB_inclusion :
    [ compile check_header1_compiles.cpp : : ]
    [ compile check_header2_compiles.cpp : : ]
    ...
    [ compile check_headerN_compiles.cpp : : ]

Even if this is simple, the creation of the file is tedious. Do you know a 
simple way to do it?

Has boost a policy about header files compilation? If not I  think that we 
need it, and that this must be as easier to do as possible, for example by 
declaring the list of header files that need to pass this check.

test-suite LIB_inclusion :
    [ check_header_compiles : header1.hpp header2.hpp  ... headern.hpp : ]

I have not tried to define the rule check_header_compiles using bjam, but I 
suppose that this is possible.
Has some one already do something similar?

What do you think?

Vicente
