[UTF] expected constructor, destructor, or type conversion before ‘(’ token

Hi, Today, I tried to build Unit Test examples on my Linux box and without success so far. I use Ubuntu Breezy, so installed Boost from packages. It seems to be Boost 1.33 version: http://packages.ubuntu.com/breezy/libs/libboost-test1.33.0 GCC on my box is: mloskot@dog:~$ g++ --version g++ (GCC) 4.0.2 20050808 (prerelease) (Ubuntu 4.0.1-4ubuntu9) Next, I checkouted Boost sources from CVS to have latest examples on my disk. As a first test I tried to build boost/libs/test/example/unit_test_example_04.cpp that mainly presents usage of BOOST_AUTO_TEST_SUITE and BOOST_AUTO_TEST_CASE macros. Here is error message I got: mloskot@dog:~/dev/boost/_cvs/boost/libs/test/example$ g++ -Wall unit_test_example_04.cpp -lboost_unit_test_framework unit_test_example_04.cpp:15: error: expected constructor, destructor, or type conversion before ‘(’ token unit_test_example_04.cpp:17: error: expected constructor, destructor, or type conversion before ‘(’ token unit_test_example_04.cpp:25: error: expected constructor, destructor, or type conversion before ‘(’ token unit_test_example_04.cpp:34: error: expected constructor, destructor, or type conversion before ‘;’ token unit_test_example_04.cpp:39: error: expected constructor, destructor, or type conversion before ‘(’ token unit_test_example_04.cpp:48: error: expected constructor, destructor, or type conversion before ‘(’ token unit_test_example_04.cpp:51: error: expected constructor, destructor, or type conversion before ‘(’ token unit_test_example_04.cpp:58: error: expected constructor, destructor, or type conversion before ‘;’ token mloskot@dog:~/dev/boost/_cvs/boost/libs/test/example$ Nothing more. I also tried to compile example as simple as possible example: #include <boost/test/unit_test.hpp> BOOST_AUTO_TEST_CASE( test1 ) { // with or without some check //BOOST_CHECK( true ); } but with the same results: mloskot@dog:~/dev/geos/_cvs/geos/tests/unit$ g++ -Wall -lboost_unit_test_framework envelope_class_test.cpp envelope_class_test.cpp:2: error: expected constructor, destructor, or type conversion before ‘(’ token I really don't have any idea what's going wrong. I tried to find some help in lists archives and the only similar problem I found is not very helpful: http://thread.gmane.org/gmane.comp.lib.boost.devel/115540 It's a bit old post and I use much newer Boost, 1.33, so it seems this post does not apply to my case. Could anyone explain me how to fix it? Honestly, I suppose that I should build Boost 1.34 from CVS but I'm not sure. I use 1.34 on Windows with VC++ 8.0 and compile my own test units and examples without problems. But I'd strongly prefer to use latest stable Boost in my project, just to not to force users to build Boost themself. Here I include (long) headers inclusion path generated by g++ -H: mloskot@dog:~/dev/boost/_cvs/boost/libs/test/example$ g++ -H -Wall unit_test_example_04.cpp -lboost_unit_test_framework .

Build a Universal Binary Boost library for Mac OSX
by Jwahar Bammi 13 Mar '06

13 Mar '06

Will appreciate a clear recipe to build Universal Binary boost libraries for Mac OSX (darwin). Boost is so wonderful, cant say the same for bjam ,,,,,,, Google'ing only pointed to the adobe patch I tried the adobe patch. Patched boost_1_33_1/tools/build/v2/tools/ darwin.jam then issued bjam -sarch=fat -sARCH=fat -sTOOLS=darwin stage (then install) did not make universal .dylibs. I suspect its got something to do with v1 vs v2 bjam or some such, i am just not grokking it. Will appreciate a ccokbook style recipe (have no particular desire to learn bjam) thanks bammi AT memento-inc DOT com

lambda and typeof, finally an effective in-place arithmetic metafunction generator.
by pongba 13 Mar '06

13 Mar '06

Okay, just image some sort of code like this: typedef mpl::vector_c<int,1,2,3> v; typedef mpl::accumulate<v,int_<0>,MPL_METAFUNC(_1*CONS(10)+_2)>::type::value result_value; // =123 Imaginably, the implementation of MPL_METAFUNC would involve BOOST_TYPEOF to deduce the type of "_1*CONS(10)+_2" so as to construct a corresponding metafunction, that is, "mpl::plus<_2,mpl::times<_1,int_<10> > >" (CONS here is used to work around the embarrassment that 10 becomes sort of variable when passed directly to operator*, so we use CONS(10) which expands into something like "int_<10>()" which entirely preserve "10" at compile-time). Arguably this is feasible, but I lack the time to implement it fully. (although it would be pretty simple, e.g. #define DEFINE_BINARY_OP(op,mpl_binray_op) \ template <typename T, typename U> \ mpl_binary_op<T,U> operator op (T t, U u) \ { \ return mpl_binary_op<T,U>(); \ } \ DEFINE_OP(+,mpl::plus) DEFINE_OP(-,mpl::minus) DEFINE_OP(*,mpl::times) DEFINE_OP(/,mpl::divide) ... Admittedly, there exists a name confliction between mpl::_1 and lambda::_1 due to the inherent difference between type and variable in the language, so we couldn't use the same _1 and _2 in both "plus<_1,_2>" and "_1+_2". Any good remedies for that?(of course we could always turn to "_1()+_2()" in which _1/2 means mpl::_1/2) My question is: Is this valuable?(IMO,it'll make arithmetic operation in metaprogramming much easier and clearer, just watch "_1*10+_2" v.s. "mpl::plus<_2,mpl::times<_1,int_<10> > >" you'll see that). And if it is, would Dave consider adding it to MPL? Thanks in advance! -- Regards!

serialization : XML Schema?
by m.korbosli 13 Mar '06

13 Mar '06

Hi, I 'm working on a project where I want to parse XML archives generated by boost serialization library, except that I didn't find any serialization's specification or XML schema describing this mechanism. Is there any documentation providing this? Thanks Accédez au courrier électronique de La Poste : www.laposte.net ; 3615 LAPOSTENET (0,34 /mn) ; tél : 08 92 68 13 50 (0,34/mn)

boost::serialization doesn't support iterators?
by 'Carlo Wood' 13 Mar '06

13 Mar '06

I looked for hours in the docs, because I couldn't believe that a serialization library that supports deep copying of pointers and STL containers wouldn't even MENTION iterators (after all, iterators are the pointers of the STL). However, it seems that boost::serialization simply does not support serializing iterators! Is this true? I really need to serialize iterators, how can I do that? -- Carlo Wood <carlo(a)alinoe.com>

Syntax of get for Variant and any_cast for Any
by Scott Meyers 13 Mar '06

13 Mar '06

It took me a little while to figure out that get<T> on a variant is really just the moral equivalent of dynamic_cast<T> with a funny syntax. I'd like to understand why, given a variant v, this syntax is used T* p = get<T>(&v); T& r = get<T>(v); instead of this: T* p = variant_cast<T*>(&v); T& r = variant_cast<T&>(v); any_cast on pointers also uses what I consider to be a counterintuitive syntax, using this (for an any object a) T* p = any_cast<T>(&a) instead of this: T* p = any_cast<T*>(&a) However, any_cast to a reference works with a syntax analogous to dynamic_cast. Implementing the "expected" syntax doesn't seem to be too difficult. For example, here's my quick cut at variant_cast: template<typename T, typename U1, typename U2, typename U3> T variant_cast(boost::variant<U1, U2, U3>& v) // ref { using namespace boost; BOOST_STATIC_ASSERT(is_reference<T>::value); return get<remove_reference<T>::type>(v); } template<typename T, typename U1, typename U2, typename U3> T variant_cast(const boost::variant<U1, U2, U3>& v) //ref-to-const { using namespace boost; BOOST_STATIC_ASSERT(is_reference<T>::value); return get<remove_reference<T>::type>(v); } template<typename T, typename U1, typename U2, typename U3> T variant_cast(boost::variant<U1, U2, U3> *pv) // ptr { using namespace boost; BOOST_STATIC_ASSERT(is_pointer<T>::value); return get<remove_pointer<T>::type>(pv); } template<typename T, typename U1, typename U2, typename U3> T variant_cast(const boost::variant<U1, U2, U3> *pv) // ptr-to-const { using namespace boost; BOOST_STATIC_ASSERT(is_pointer<T>::value); return get<remove_pointer<T>::type>(pv); } In a thread last month, Marc Mutz posted this approach to "normalizing" the syntax of any_cast: template <typename T> class any_cast2 : noncopyable { const any & m_any; public: explicit any_cast2( const any & v ) : m_any( v ) {} operator T() const { return any_cast<T>( m_any ); } }; template <typename T> class any_cast2<T*> : noncopyable { any * const m_any; public: explicit any_cast2( any * v ) : m_any( v ) {} operator T * () const { return any_cast<T>( m_any ); } }; template <typename T> class any_cast2<const T*> : noncopyable { const any * const m_any; public: explicit any_cast2( const any * v ) : m_any( v ) {} operator const T * () const { return any_cast<T>( m_any ); } }; template <typename T> class any_cast2<T&> : noncopyable { any & m_any; public: explicit any_cast2( any & v ) : m_any( v ) {} operator T & () const { return any_cast<T&>( m_any ); } }; template <typename T> class any_cast2<const T&> : noncopyable { const any & m_any; public: explicit any_cast2( const any & v ) : m_any( v ) {} operator const T & () const { return any_cast<const T&>( m_any ); } }; Maybe there are problems to these approaches -- I've hardly investigated them. But I would be interested to know if there is a good reason for the syntaxes for dynamic_cast, any_cast, and get to vary so much. Thanks, Scott
