Hi Sebastian, >This looks correct and I honestly can't see why you would still have >unresolved symbols while linking unless perhaps are you doing a debug >mode build? In which case you should use the >boost_*-vc90-mt-gd-1_36.lib import libraries. Thank you for thinking about that. Actually I do have the /MTd and /MDd variants as well, but did not mention them to keep it small :) So will try to fiddle around and post the solution here ... if i find it.

Re: [Boost-users] dynamic link error: boost::program_options::arg not found

Hello Sebastian and thank you for the follow up, I must precise that I have 2 builds of my projects: one linking to the multi threaded static runtime (/MT) and one linking to the multithreaded dynamic runtine (/MD). I defined BOOST_ALL_NO_LIB=1 to disable autolinking, and i am linking manually to libboost_filesystem-vc90-mt-s-1_36.lib libboost_program_options-vc90-mt-s-1_36.lib and libboost_system-vc90-mt-s-1_36.lib for the /MT variant, and to boost_filesystem-vc90-mt-1_36.lib, boost_program_options-vc90-mt-1_36.lib and boost_system-vc90-mt-1_36.lib for the /MD variant. For _both_ variants, I get stuck with following unresolved externals: __declspec(dllimport) public: void __thiscall boost::program_options::detail::cmdline::set_additional_parser(...) __declspec(dllimport) class boost::system::error_category const & __cdecl boost::system::get_generic_category(void) __declspec(dllimport) class boost::system::error_code boost::filesystem::detail::throws What is more suprising, is that for the dynamic version, the set_additional_parser export _does_ appear when I dumpbin /exports ./boost_program_options-vc90-mt-1_36.lib | grep set_additional_parser but the two other symbols do not appear in boost_system-vc90-mt-s-1_36.lib. Any idea what I am getting wrong ? Beginning to feel lost.

E.g.: dumpbin /exports ..\boost_1_36_0\lib.x86-nt-msvc8\boost_program_options-vc80-mt-gd-1_36.lib | grep program_options::arg The "non dll-interface" warnings are OK, but am I missing something or are you not linking against boost_program_options-*.lib ? I have to say that I currently don't use auto linking maybe you should try adding all libraries manually and turn off the auto linking feature by defining: BOOST_ALL_NO_LIB=1. Regards, Sebastian

I looked at your examples but think that you can abstract better. I don't think one should have to use sendmessage for example. Not that I do much .net dev, but I did find that winforms was the easiest ui framework I have seen. I think applying c++ and boost idioms to a winforms inspired api would be well received by many ------Original Message------ From: Felipe Magno de Almeida Sender: To: boost-users(a)lists.boost.org ReplyTo: boost-users(a)lists.boost.org Sent: Sep 18, 2008 1:33 PM Subject: Re: [Boost-users] offtopic: std C++ / STL / boost-friendly UIframework?

I'm developing cppgui. It has some widgets, and only works for win32 for now. http://www.assembla.com/wiki/show/cppgui It doesn't have any documentation, but it does have some examples. I find the interface *very easy* to use, but it is still quite incomplete. I have a few code for gtk+ but it is not working right now, I will do a rewrite of the gtk+ support for the lib in the near future.

Just idle curiosity really, but what causes the Boost major version number to be incremented? Ie., Boost version 2.0? - Rob.

Umm, just out of interest, what *is* Wascana supposed to be? The site just calls it "Desktop Developer" and while it does mention Eclipse I'm not at all clear how it's related. I've jumped around the site but wasn't able to locate any explanation of what it really is. It does mention that it 'incorporates' (among other things) wxWidget and intends to 'incorporate' boost, but what is 'incorporate' supposed to mean? JRE is listed as well (but also gdb), so again I'm wondering what is this thing? As an aside, last I looked Eclipse was Java only, so why would Wascana be of help for C++ development when it's aimed at Eclipse (or so I understand it for now) Sorry if I'm being dumb, the issue interests me for private purposes and I've got to admit I'm a bit out of touch with UI development tools atm.

[test] How to ignore a signal?
by Boris 19 Sep '08

19 Sep '08

I've a test case which receives the SIGCHLD signal on Solaris. Boost.Test catches it and prints an error message although in that test case SIGCHLD s perfectly fine. How do I make Boost.Test ignore this signal? I found BOOST_NO_SIGNAL_HANDLING back in Boost.Test 1.33.1 but it doesn't seem to exist anymore in 1.36.0? Boris

[test] memory access violation by calling <<-operator
by M. Siebeneicher 18 Sep '08

18 Sep '08

Hi boost-users, I created a class and overload the <<-operator. Now I tried to test them by assigning an instance of the class to an ostringstream, but I get always the error: "fatal error in "EmptyVertex_output_stream": memory access violation occurred at address 0xcccccce0, while attempting to read inaccessible data" It's very curious, because assigning a string directly to the ostringstream, no error occurs. I'm using boost 1.35.0 and VS2003 The code: // test_class.cpp BOOST_AUTO_TEST_CASE( EmptyVertex_output_stream) { // 1 // const string vertexNameIn1 = "test name"; const EmptyVertex emptyVertex1(vertexNameIn1); ostringstream currString1; currString1 << emptyVertex1; // Error occurs here, see class_to_test.cpp string expString1 = "EmptyVertex(name=test name)"; BOOST_CHECK_EQUAL(currString1.str(), expString1); } //class_to_test.cpp /*public friend*/ ostream& operator<<(ostream& streamOut, const EmptyVertex& vertex) { streamOut << "EmptyVertex("; // Error occurs here streamOut << vertex.getName(); streamOut << ")"; return streamOut; } Can someone give me a clue? greetz, modbom -- Ist Ihr Browser Vista-kompatibel?

[boost-users][logging] limiting/truncation the output file
by Igor R 18 Sep '08

18 Sep '08

Hello, I know the above library is not a part of the boost yet, but probably some of you had an experience with it. I log to a text file. What I need is to ensure that the file doesn't exceed some maximal size. For the sake of simplicity, I'd like just to re-create the file when it grows to much. I guess I may not just delete it externally, as it's managed by the logger. So how can I tell the logger to delete the file? (Ideally, I'd like to "scroll" the data in the file like in a queue - first in first out, but I guess it's impossible, isn't it?) Thank you, Igor'.
