Hi.
I'd like a little guidance regarding the use of
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
.
That's all good so far and the following example compiles and runs.
------------------------
// Main.cpp
#define BOOST_TEST_MODULE Main
#include
------------------------
// Test1.cpp
#include
BOOST_AUTO_TEST_CASE(test1)
{
BOOST_CHECK(true);
}
------------------------
// Test2.cpp
#include
BOOST_AUTO_TEST_CASE(test2)
{
BOOST_CHECK(true);
}
------------------------
My problem arises when I try to include in a
precompiled header.
------------------------
// Pch.h
#ifndef PCH_H_INCLUDED
#define PCH_H_INCLUDED
// Boost headers.
#include
#endif // PCH_H_INCLUDED
------------------------
// Main.cpp
#define BOOST_TEST_MODULE Main
#include
------------------------
// 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 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
#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.
