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

I am not really an expect on precompiled headers
usage, but I believe your problem might be caused
by usage of unnamed namespace in Boost.Test headers.
Usually it can be worked around by adding extra static.
I'll look into fixing this.
Would you mind opening a ticket for this?
