problem with boost::shmem on Solaris 10 Sun Studio 11
by Clarke, Trevor 31 Aug '06

31 Aug '06

I'm trying to use boost::shmem and I'm having trouble on Solaris. The same code works fine on Windows with VS8. I'm getting: Error: Redefining boost::shmem::detail::segment_manager<boost::shmem::detail::CharType, ... After use in boost::shmem::detail::segment_manager<char, boost::shmem::simple_seq_fit... The offending line in boost::shmem is typedef segment_manager<CharType, MemoryAlgorithm, IndexType> segment_manager; in boost::shmem::detail::segment_manager::index_config The code in my application is mpLast->mNext = reinterpret_case<my_list_node*>(mpSegment->construct<my_list_node>(boost ::shmem::anonymous_instance)()); whieh mpSegment is a segment_manager*. Any idea what is going on? -------------------- Trevor R.H. Clarke tclarke at ball.com <mailto:tclarke@ball.com> Ball Aerospace & Technologies Corp

Graph - compiling with gcc-4.1.1
by Todd A. Gibson 31 Aug '06

31 Aug '06

I have code utilizing the boost graph library. It has compiled fine for some time under gcc-3.x and fails on gcc-4.1.1 (x86-32). Pasted at the end of this message are the relevant compile errors. A quick google search reveals that two other folks have reported this same error (in different boost graph-using applications) with gcc-4.1 using different Linux distributions. My questions are: 1) Has this been reported here before? 2) If yes, has a patch been posted? My graph code lies beneath several layers of application code, so I wanted to check here before spending the time trying to build a simple test case which reproduces the error. Thanks. -TAG Todd A.

[regex] - Bug in boost::regex ??
by kiran 31 Aug '06

31 Aug '06

Hi I am trying to extract a pattern from a file. Actually there are 2 occurances of the pattern in the file, one in line 2-3 and other in line 4. But the program is only reporting the occurance in line 4. The reason why i am giving (.|\n) coupled 'match_not_dot_newline' with is that i want the regex to be perl compatible. Why is the program not reporting the first occurance ? Is this a bug ? I am attaching the code and file. Thanks Kiran.

Using regex on a file
by Dave 31 Aug '06

31 Aug '06

Hello all, I would like to programmatically search a (large) binary file for a particular text string and get a boolean result back - either the string appeared or it did not. I imagine whatever I end up implementing will be platform-independent, but I'll state anyway that I am using Visual C++. My first thought was to use regex_search and pass it two stream iterators, one pointing to the beginning of the file and one representing the end of the file. Alas, this won't work since regex_search requires bidirectional iterators, which stream iterators are not. I would appreciate any suggestions as to how I can most efficiently and elegantly achieve my goal. Thank you! Dave

[Serialization] Runtime error in release but not in debug builds (Visual C++ 8)
by Dieter Buys 31 Aug '06

31 Aug '06

Hi, My program is now crashing when I do a release build and try to serialize my data, but in the debug version it works just fine. Area where it is crashing appears to be: std::ofstream ofs(saveAsDialog.GetPath()); boost::archive::binary_oarchive oa(ofs); Specifically on the second line, where it attempts to create the archive on the file stream, it just crashes. At this point I have no idea what could be causing it. I am using MS Visual C++ 8. Cheers, Dieter Buys

Alas, this won't work since regex_search requires bidirectional > iterators, which stream iterators are not. You might consider using a file_iterator from Spirit. It is a random-access iterator for files, which sounds like exactly what you need. Check it out at http://www.boost.org/libs/spirit/doc/file_iterator.html. -- Todd

Problem building 1.33.1 for Intel Mac -- Seeking patches if they exist.
by Bennett Smith 30 Aug '06

30 Aug '06

Hi, I am attempting to build Boost 1.33.1 for an Intel Mac. Some of the libraries do not build successfully, and I think it is related to the different architecture. One of the errors I get is: ld: Undefined symbols: __Z9test_mainiPPc Does anyone have patches for Boost 1.33.1 that would make it build everything successfully on an Intel Mac? BTW, I also tried doing a build of the 1.34.0 release candidate files and everything there seems to build fine. I just don't really want to base our project on 1.34 until it is officially released. Thanks for any help you can offer. Cheers -- Bennett

I think if this functionality were added, it should NOT be called Boost.Bio or refer to bioinformatics in any way, because this isn't bioinformatic-specific. But in general adding these string algorithms would be useful - they are used in many fields. - James Jones Administrative Data Mgmt.

is mpl::for_each depricated?
by Ovanes Markarian 30 Aug '06

30 Aug '06

Hi! Unfortunately I can not find online documentation for the mpl::for_each algorithm. Which I know from C++ Metaprogramming book. Is it depricated? I need at least the header file name. Would be nice if docs would be updated, at least stating, that this function is depricated. With Kind Regards, Ovanes Markarian
