[serialization] CW8 status...
by Rene Rivera 04 Aug '04

04 Aug '04

Robert, A quick summary of what your recent changes did for CW8, in case the metacomm tests don't soon: * test_delete_pointer pass. * test_demo_auto_ptr pass. * test_deque pass. * test_diamond pass. * test_map pass. * test_non_default_ctor pass. * test_non_intrusive pass. * test_optional pass. * test_private_ctor pass. * test_split pass. * test_vector pass. I only tested the previous failures. And for some the metacomm tests show a failure for things were previously fixed. Also it looks like some of the failures are now different, meaning you fixed something only to have it fail on something else. -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com - 102708583/icq

serialization test all fail on darwin
by Robert Ramey 04 Aug '04

04 Aug '04

I'm getting all failures in the serialization library on Darwin - gcc 3.1 A few days ago I got all passes for this platform(exception wide char xml - a separate issue). I had hoped it my go away spontaneously - as it arrived - but no luck. Does anyone have a suggestion on how to address this?

[string algo] Documentation errors
by Jeff Garland 03 Aug '04

03 Aug '04

I've been writing some code with string algorithms and I noticed a couple documentation issues: 1) First example: #include <boost/string_algo.hpp> should be #include <boost/alogorithm/string.hpp> 2) In the 'split' section example: typedef vector< string > split_vector_type; split_vector_type SplitVec; // #2: Search for tokens split( SplitVec, str1, is_any_of<char>("-*") ); // SplitVec == { "hello abc","ABC","aBc goodbye" } This doesn't work for me on gcc3.3.2 Linux (passes all regression tests) and it conflicts with the documentation of is_any_of which takes a collection not a char string as the parameter.

Re:[boost] Re: [program_options / g++ 3.3.3] Problem with UTF-8codecvt facet
by Robert Ramey 03 Aug '04

03 Aug '04

Tilman Kuepper >If a new version of the UTF-8 facet is available it may find its way >into other libraries, e. g. program_options, serialization etc. We have agreed to use Vladimir's version of this library. The serialization library has its own copy but that will disappear when I get some unrelated issues sorted out. Robert Ramey

3 important Intel regressions and some other stuff
by Stefan Slapeta 03 Aug '04

03 Aug '04

The following regressions seem to be special to Intel 8: - numeric/uBLAS The only way to solve this seems at the moment not to use the "Multithreaded Debug DLL" runtime. When we can isolate the problem, Intel should investigate. - Python The slice test case is failing! Any ideas? - random error: no operator "<<" matches these operands I've not heard any comment in the last days about that. Any ideas? Aleksey, could we have a link to http://boost.sourceforge.net/regression-logs/developer/python.html on the boost regression site? I can't find any link to this page anywhere. I'm now going to leave now and I'll return on Sunday. I don't know if I can manage to get the regressions being run automatically, otherwise you get the next results for Intel 8 + CW 9 on Sunday.

[multi_index] spurious error in CW 9
by Joaquín Mª López Muñoz 03 Aug '04

03 Aug '04

This test occasionally fails: http://tinyurl.com/72xcb but there's no error output or any failure indication, nothing. The problem shows only at times, so I guess it'll have to do with the compiler being low on resources, but couldn't say for sure. Any idea?

[regression] Discrepancy with display and results...
by Rene Rivera 03 Aug '04

03 Aug '04

I just noticed a discrepancy between the regression tables, the MetaComm one's, and the output reported for the failure. If one looks at the Spirit summary: http://www.boost.org/regression-logs/cs-win32_metacomm/developer/spirit.html Boost regression: spirit/CVS main trunk There are two failures, action_tests and action_tests_debug. But if one looks at either for the failure, you see that there is no failure: Boost regression - test run output: spirit - action_tests / cwpro8 Compiler output: call "C:\Program Files\Metrowerks\CodeWarrior\Other Metrowerks Tools\Command Line Tools\cwenv.bat" -quiet mwcc -maxerrors 5 -maxwarnings 20 -c -warn on,nounusedexpr,nounused -cwd include -DNOMINMAX -nowraplines -lang c++ -g -O0 -inline off -prefix UseDLLPrefix.h -runtime dmd -iso_templates on -I"C:\Users\Administrator\boost\main\results\bin\boost\libs\spirit\test" -I"..\libs\spirit" -I".." -I- -I"C:\Users\Administrator\boost\main\boost" -o "C:\Users\Administrator\boost\main\results\bin\boost\libs\spirit\test\action_tests.test\cwpro8\debug\unit_test.obj" "..\libs\spirit\test\./actor/unit_test.cpp" Linker output: call "C:\Program Files\Metrowerks\CodeWarrior\Other Metrowerks Tools\Command Line Tools\cwenv.bat" -quiet mwld -search -maxerrors 5 -maxwarnings 20 -export dllexport -nowraplines -g -subsystem console -o "C:\Users\Administrator\boost\main\results\bin\boost\libs\spirit\test\action_tests.test\cwpro8\debug\action_tests.exe" @"C:\Users\Administrator\boost\main\results\bin\boost\libs\spirit\test\action_tests.test\cwpro8\debug\action_tests.CMD" Run output: Running 14 test cases... *** No errors detected EXIT STATUS: 0 -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com - 102708583/icq

Another project based on Boost Graph
by Jonah Beckford 03 Aug '04

03 Aug '04

I would like to thank the Boost Graph implementers (and the general Boost community) for coming up with a great set of patterns for dealing with graphs. I have started something similar for Scheme (a Lisp dialect), and would like to acknowledge where the great ideas came from. Keep up the good work! Jonah http://www.nongnu.org/rgraph/ README excerpt: Rooster Graph is a graph library for Scheme. Patterned after the popular Boost Graph Library for C++, it allows for a very clean separation between the graph container and graph algorithms. It does not have the complete functionality of the Boost Graph Library, but it does go a bit further by having both strict- and lazy-evaluated methods; the user of the graph has pause/continue/stop control and is not constrained by memory. Rooster Graph uses Scheme macros to get the benefit of speed while having generic operations. It has only been implemented on CHICKEN Scheme, although porting it to other Scheme implementations would be quite easy.
