Re: [Boost-users] Inconsistent dll linkage trying to use boost/test as dll
by McNamara, Nate 17 Apr '10

Thanks for the quick response. Your hint plus a few tweaks to the Makefile and the test compiles again - and much faster. Unfortunately, when I run the test, I get the following unhelpful message: The application failed to initialize properly (0xc0150002). Click on OK to terminate the application. Here is the entirety of my program: #define BOOST_TEST_MODULE foo #define BOOST_TEST_DYN_LINK #include <boost/test/unit_test.hpp> BOOST_AUTO_TEST_CASE(my_test) { BOOST_CHECK_EQUAL(4, 4); } I got the same error when I tried #define BOOST_TEST_MAIN in place of BOOST_TEST_MODULE as well; as far as I can tell from the docs they are equivalent when using the dynamic library variant: http://www.boost.org/doc/libs/1_42_0/libs/test/doc/html/utf/compilation. html Thanks again for your help!

[Spirit] still stuck on expectation points
by philip tucker 17 Apr '10

17 Apr '10

Hello, Here's a summary of my problem: My original fully functioning grammar was this: start %= (constitkind >> id >> ':' >> id >> probs) % ","; // WORKS where - constitkind exposes unsigned, - id exposes string, - probs exposes a list of doubles, - start exposes a list of constituent structures (Is that jargon acceptable?) It recognizes strings such as a:b, foo:bar [ 0.00 ], extraposed x:y [ 0.00, 0.50, 0.99, 1.0 ], optional z:a [ 0.00, 0.50, 0.99, 1.0 ] I wanted to replace the grammar with this (note the expectation points which replace sequence operators): start %= (constitkind > id > ':' > id >> probs) % ","; // FAILS That won't compile. All I can glean from the error report is that I've induced a type mismatch. What's wrong? I got as far as this by thrashing: start %= (constitkind >> (id > ':') >> id >> probs) % ","; // WORKS Why do the parentheses in (id > ':') permit compilation? Thanks very much for any help you can give me.

Compiler's telling me a Boost class isn't a class.
by G S 17 Apr '10

17 Apr '10

Hi all. Just started using Boost, and these three lines (which compile in another project) fail here: // Get a list of endpoints corresponding to the server name. tcp::resolver theResolver(boost::asio::io_service); tcp::resolver::query query("10.10.10.10", "http"); tcp::resolver::iterator endpoint_iterator = theResolver.resolve(query); The compiler gripes thus: error: request for member 'resolve' in 'theResolver', which is of non-class type 'boost::asio::ip::basic_resolver<boost::asio::ip::tcp, boost::asio::ip::resolver_service<boost::asio::ip::tcp> > ()(boost::asio::io_service)' "using boost::asio::ip::tcp;" appears in an earlier included file. I don't see why this would work elsewhere and not here. Anybody have a guess as to what the problem is? Thanks!

[test] spread case over multiple translation units
by Jeff Flinn 16 Apr '10

Is it possible have multiple cpp's linked for a single master test suite? Doing the naive below results int multiply defined symbols linker errror. See below: suite1.cpp ------------------------------------- #define BOOST_TEST_MAIN #define BOOST_TEST_MODULE Master #include <boost/test/unit_test.hpp> BOOST_AUTO_TEST_SUITE(Sweet1) BOOST_AUTO_TEST_CASE(TestCase1) { BOOST_CHECK (true); BOOST_REQUIRE(true); BOOST_REQUIRE(true); BOOST_CHECK (true); } BOOST_AUTO_TEST_CASE(TestCase2) { BOOST_CHECK (true); BOOST_REQUIRE(true); BOOST_REQUIRE(true); BOOST_CHECK (true); } BOOST_AUTO_TEST_SUITE_END() suite2.cpp ------------------------------------------ #define BOOST_TEST_MAIN #define BOOST_TEST_MODULE Master #include <boost/test/unit_test.hpp> BOOST_AUTO_TEST_SUITE(Sweet2) BOOST_AUTO_TEST_CASE(TestCaseA) { BOOST_CHECK (true); BOOST_REQUIRE(true); BOOST_REQUIRE(true); BOOST_CHECK (true); } BOOST_AUTO_TEST_CASE(TestCaseB) { BOOST_CHECK (true); BOOST_REQUIRE(true); BOOST_REQUIRE(true); BOOST_CHECK (true); } BOOST_AUTO_TEST_SUITE_END()

UTF : capturing asserts
by Carla Strembicke 16 Apr '10

16 Apr '10

Hi, Just started using the BOOST unit test framework. I have legacy code that exercises asserts. This resided on both a linux and windows platform. Using 1.42 release of boost. Is there a method in which to capture assert so as to pass a test ( like BOOST_REQUIRE_THROW)? It is either that, compile code without debug on ( which I wouldn't want to do if debugging) or replace all asserts which would be painful considering it is legacy code.

Inconsistent dll linkage trying to use boost/test as dll
by McNamara, Nate 16 Apr '10

16 Apr '10

I'm a newbie, and I'm trying to get the most basic example unit test up and running. The following works: #define BOOST_TEST_MAIN #include <boost/test/included/unit_test.hpp> BOOST_AUTO_TEST_CASE(my_test) { BOOST_CHECK_EQUAL(4, 4); } However, it takes a while to compile, so I want to use the DLL version of the library. I built the DLL according to the instructions here: http://www.boost.org/doc/libs/1_42_0/libs/test/doc/html/utf/compilation/ standalone.html Then I updated my source as follows: #define BOOST_TEST_DYN_LINK #include <boost/test/included/unit_test.hpp> BOOST_AUTO_TEST_CASE(my_test) { BOOST_CHECK_EQUAL(4, 4); } When compiling the above, though, I get a seemingly unending stream of C4273 warnings: C:\Program Files\\boost\boost_1_42\boost/test/impl/compiler_log_formatter.ipp(61 ) : warning C4273: 'boost::unit_test::output::compiler_log_formatter::log_start' : inconsistent dll linkage C:\Program Files\\boost\boost_1_42\boost/test/output/compiler_log_format ter.hpp(39) : see previous definition of 'log_start' C:\Program Files\\boost\boost_1_42\boost/test/impl/compiler_log_formatter.ipp(71 ) : warning C4273: 'boost::unit_test::output::compiler_log_formatter::log_finish ' : inconsistent dll linkage C:\Program Files\\boost\boost_1_42\boost/test/output/compiler_log_format ter.hpp(40) : see previous definition of 'log_finish' C:\Program Files\\boost\boost_1_42\boost/test/impl/compiler_log_formatter.ipp(79 ) : warning C4273: 'boost::unit_test::output::compiler_log_formatter::log_build_ info' : inconsistent dll linkage etc. Any hints re: what I'm doing wrong are much appreciated.

[boost.test] 0 return code with expected failures?
by Ahmed Badran 16 Apr '10

16 Apr '10

Hi, I have a binary that runs unit tests, 3 tests fail and these tests I have marked as being expected failures after analysis. The binary however produces a non-zero exit code even with these tests marked as expected failures . Is there a way to have the binary return a zero exit code when all the failures are expected and non-zero when some other non-expected failure happens? The test setup uses automatic test registration. Regards, Ahmed

BOOST_HAS_RVALUE_REFERENCES and Visual Studio 2010 support
by Marat Abrarov 16 Apr '10

16 Apr '10

As I see Boost C++ Libraries (1.42) doesn't support rvalue references under Visual C++ 10.0 (Visual Studio 2010) - there is no definition of BOOST_HAS_RVALUE_REFERENCES (and BOOST_NO_RVALUE_REFERENCES too) for Visual C++ 10.0. Does anybody know why it is so and when will it be supported? (and will it be so?) Regards, Marat.

SVG Graphics - to be supported by IE9 - Boost GSoC project?
by Paul A. Bristow 16 Apr '10

16 Apr '10

Some may remember that Jake Voytko worked on a SVG graphic plotting package during a 2007 GSoC - dubbed Boost.Plot. In July 2009, I announced that this was available for people to 'try out' - it seems in a usable condition. Although several people made some kind remarks about it, I sensed that the 'killer' feature was using SVG SVG was *NOT supported 'out-of-the-box'* by Microsoft IE (including 8, to my surprise, and disappointment). It now seems that Microsoft have 'seen' the light' and promise that IE 9 will provide good and portable support for SVG. http://blogs.msdn.com/ie/archive/2010/03/18/svg-in-ie9-roadmap.aspx They have finally realised the 'small is beautiful' applies to graphics - especially now that many are being displayed on phones with limited speed links. SVG graphics need a tiny amount of code, especially when compressed, and can be expanded without 'going all pixelly'. Boost.Plot is special in that it is in C++ and it has a Boost license. It allows you to add just a few lines of code to the end of your C++ program to take data from any STL container (all or part) and produce a plot as a Scale Vector Graph (.svg) file. So it is already suited to sending near real-time plots to phones. BUT while Boost.Plot provides zillions of functions to TechniColor your XY plots, it doesn't do much to help produce other displays - even things as simple as pie charts. And the underlying SVG interface functions are perhaps rudimentary. So I wonder if there is any enthusiasm for a Google Summer of Code project for NEXT summer 2011 to get this into a reviewable state? (Sadly I think we have just missed GSoC for this year). Paul PS A few demo plots are attached for your amusement. The latest version is available on SVN https://svn.boost.org/svn/boost/sandbox/SOC/2007/visualization/ Docs are available to build as html and pre-built as pdf (patience - 6 Mbyte!) https://svn.boost.org/svn/boost/sandbox/SOC/2007/visualization/libs/svg_plot /doc/pdf/svg_plot.pdf or http://tinyurl.com/coqlbg (or ask if you want zips instead). --- Paul A.
