Test library fails to link on OS X 10.3 Panther

Scott Lamb! I have the exact same set up as you have and I end up with the same error message as you do. Same as your earlier message: I've downloaded boost-1.30.2 and boost-jam-3.1.7 to my PowerBook running Mac OS X 10.3 (Panther). After installing boost-jam without problems, I'm attempting to build the boost test library as follows: $ uname -a Darwin spiff.local 7.2.0 Darwin Kernel Version 7.2.0: Thu Dec 11 16:20:23 PST 2003; root:xnu/xnu-517.3.7.obj~1/RELEASE_PPC Power Macintosh powerpc $ gcc_select Current default compiler: gcc version 3.3 20030304 (Apple Computer, Inc. build 1495) $ cd boost-1.30.2/libs/test/build $ bjam -sTOOLS=darwin ----- Same errors as you: ...failed darwin-Link-DyLib-action libs/test/build/bin/libboost_prg_exec_monitor.dylib/darwin/debug/ runtime-link-static/shared-linkable-true/ libboost_prg_exec_monitor.dylib... ... ...failed darwin-Link-DyLib-action libs/test/build/bin/libboost_test_exec_monitor.dylib/darwin/debug/ runtime-link-static/shared-linkable-true/ libboost_test_exec_monitor.dylib... ... ...failed darwin-Link-DyLib-action libs/test/build/bin/libboost_unit_test_framework.dylib/darwin/debug/ runtime-link-static/shared-linkable-true/ libboost_unit_test_framework.dylib... ... ...failed updating 6 targets... ...updated 283 targets...

compilation problem with property_map?
by lr 27 Jan '04

27 Jan '04

hello all, i was wondering if anyone could help me with this compilation error. gcc indicates that the error is in put(), specifically it cannot match the operator for [bool&] on property_map.hpp:316. the full output is included below. the origin of the error is caused in destructor code (when objects get out of scope in testgdlgraph.cpp). if i need to supply more information about the code i am writing let me know. i am hesitant because it is fairly complicated, as i am having trouble trying to replicate this problem in a simple example. thanks leonid ps. boost rocks, keep up the good work! the compiler error: /usr/include/boost/property_map.hpp: In function `void boost::put(const boost::put_get_helper<Reference, PropertyMap>&, K, const V&) [with PropertyMap =

vector_indexing_suite issue
by Jeff Holle 27 Jan '04

27 Jan '04

I am successfully using vector_indexing_suite in following code: class_<std::vector >("vector_B") .def(vector_indexing_suite<std::vector >()) ; However, I find that it requires that the B class conforms to the Equality Comparable concept where the STL standard only demands it to conform to the Assignable concept. I'm wondering if this is necessary, and if so how the operator== method should be coded. Can it simply always return true or false? Or compare "this" pointers?

CVS head build problem
by Jeff Holle 26 Jan '04

26 Jan '04

I downloaded the boost CVS head this morning and in attempting a re-build it, I found that my compiler, gcc v3.3, choked on the parmeter "-Wno-long-double". This problem was solved by changing line 61 of boost/tools/build/v1/gcc-tools.jam to: flags gcc CFLAGS : ; Suspect this wasn't a proper changed, but it worked for me.

boost::mpl:: operators ...power metafunction?
by Andy Little 26 Jan '04

26 Jan '04

Hi, I am implementing the mpl math operators for my physical_quantities type. Ideally I would like to declare a boost::mpl::power<A,B> metafunction. I would like to do: typedef Power_type<...> P ; pq_xx a; boost::mpl::power< pq_xx, P >::type b = run_time_power( a); OTOH: boost::mpl::power< P, pq_xx >::type b = run_time_power( a); (param order ... TBD) I am assuming it is ok to specialise plus, minus, multiplies etc in the boost::mpl namespace? I could of course put power (or whatever name) outside the boost::mpl namespace but that is not ideal. Any thoughts? regards Andy Little

bind1st and bind2nd together
by Hossein Haeri 25 Jan '04

25 Jan '04

Dear all, I've got a ternary function (which is std::find), and want to bind the first and second parameters (to the begining and the end of a std::vector). Then send the result to compose2 to check the equality for the end of the vector. Here is what I did: copy_if(istream_iterator<Terminal>(cin), istream_iterator<Terminal>(), back_inserter(temp), compose2(equal<set<Terminal>::iterator>(), bind1st(bind1st_3(ptr_fun(f), V_.begin()), V_.end()), V_.end()))); (I've prepared any goodie needed by ternary functions for the above statement: ptr_fun, bind1st_3, ...) Dev-C++ 4.9.8.0 (GCC 3.3.2 I think), gives me several errors (including "Reference to Reference" problem), and I'm nearly convinced not to continue it this way. Now, how do you, boost guys, do that?

MPL Issue in apply.hpp in CVS
by Martin Ecker 25 Jan '04

25 Jan '04

Hello, I wanted to use boost::variant, so I got the Boost libraries from CVS. While developing a small test program I discovered an issue in the MPL header file apply.hpp that prevented successful compilation on MSVC 7.1. In particular, starting on line 245 in boost/mpl/apply.hpp it says // ISO98 C++, with minor concession to vc7 template< typename F, AUX_APPLY_N_PARAMS(i, typename T) > struct BOOST_PP_CAT(apply,i) { // Metafunction forwarding confuses vc7 typedef typename F::template apply< AUX_APPLY_N_PARAMS(i, T) >::type BOOST_MPL_AUX_LAMBDA_SUPPORT( BOOST_PP_INC(i) , BOOST_PP_CAT(apply,i) , (F, AUX_APPLY_N_PARAMS(i,T)) ) }; The first typedef in that struct should be // Metafunction forwarding confuses vc7 typedef typename F::template apply< AUX_APPLY_N_PARAMS(i, T) >::type type; Regards, Martin ---------------------------------------------------------------- Visit my pages on the Web: XEngine Project Page: http://xengine.sourceforge.net Private homepage: http://members.liwest.at/GroovingArts

Interval Library?
by David Brownell 25 Jan '04

25 Jan '04

I think I am looking for functionality that is contained with the Interval library, but am having a hard time digesting the documentation for this particular library. I would like an Interval that goes from a min_value to a max_value, where each value is the previous value + N. For example, the interval {2, 6, 10, 14, 18} has a minimum value of 2, a maximum value of 18, and increments by 4. Given this interval, I would like a function, Foo, that works as follows: Interval(2, 18, 4) i; i.Foo(2) == 2 i.Foo(6) == 2 i.Foo(0) == 2 i.Foo(18) == 18 i.Foo(20) == 18 i.Foo(5) == 6 i.Foo(3) == 6 Is this something that can be done with the Interval library, or am I missing the point? :) Thanks in advance for your help!

Hello, I fairly new to the Boost tool. I have just build the Boost.Python 1.30.2. To get started I used the examples "getting_started1.cpp and getting_started2.cpp." and build the required DLLs using the bjam tool. I get following error when I try to import the module "getting_started1" into python : "ImportError: DLL load failed: The specified module could not be found." Can someone help me resolve this error? I am using PythonWin 2.2.1. Nitin
