[Boost-users] Problem with <boost/test/unit_test.hpp> in precompiled header.

Hi.

I'd like a little guidance regarding the use of <boost/test/unit_test.hpp>
please. I'm using mingw--gcc-3.4.5 with CodeBlocks 8.02. I'm dynamically
linking to boost_unit_test_framework-mgw34-d-1_36.dll via
boost_unit_test_framework-mgw34-d-1_36.lib. I have BOOST_TEST_DYN_LINK
defined and I've worked out that I need to have #define BOOST_TEST_MODULE
<whatever> defined in one source file prior to #include
<boost/test/unit_test.hpp>.

That's all good so far and the following example compiles and runs.

------------------------

// Main.cpp
#define BOOST_TEST_MODULE Main
#include <boost/test/unit_test.hpp>

------------------------

// Test1.cpp
#include <boost/test/unit_test.hpp>

BOOST_AUTO_TEST_CASE(test1)
{
        BOOST_CHECK(true);
}

------------------------

// Test2.cpp
#include <boost/test/unit_test.hpp>

BOOST_AUTO_TEST_CASE(test2)
{
        BOOST_CHECK(true);
}

------------------------

My problem arises when I try to include <boost/test/unit_test.hpp> in a
precompiled header.

------------------------

// Pch.h
#ifndef PCH_H_INCLUDED
#define PCH_H_INCLUDED

// Boost headers.

#include <boost/test/unit_test.hpp>

#endif // PCH_H_INCLUDED

------------------------

// Main.cpp
#define BOOST_TEST_MODULE Main
#include <boost/test/unit_test.hpp>

------------------------

// Test1.cpp
#include "Pch.h"

BOOST_AUTO_TEST_CASE(test1)
{
        BOOST_CHECK(true);
}

------------------------

// Test2.cpp
#include "Pch.h"

BOOST_AUTO_TEST_CASE(test2)
{
        BOOST_CHECK(true);
}

------------------------

The compiler is exiting with no errors but no output binary is produced. The
build log reports:

I do not understand why the header file <boost/test/unit_test.hpp> objects
to being included via a precompiled header file in this way. The following
simple case also works fine.

------------------------

// Pch.h
#ifndef PCH_H_INCLUDED
#define PCH_H_INCLUDED

// Boost headers.

#define BOOST_TEST_MODULE Main
#include <boost/test/unit_test.hpp>

#endif // PCH_H_INCLUDED

------------------------

// Main.cpp
#include "Pch.h"

BOOST_AUTO_TEST_CASE(test1)
{
        BOOST_CHECK(true);
}

------------------------

I'll start having a look at the Boost source and see if I can work out what
I'm doing wrong, but if anyone can see a problem with what I'm trying to do
here I'd be grateful if they could point it out for me.

Thanks
Neutrino.
