Regex Library
by Srinivas Chamarthi 11 Feb '08

11 Feb '08

Hi, I am new to C++ development and using boost regex library. I have downloaded 1_34_1 version. I have built regex library and it created boost_regex-vc80-mt-*1_34*.lib & dll files for me. But when I included headers and compiled my application but its giving me the following linker error. - *Error 1 fatal error LNK1104: cannot open file 'boost_regex-vc80-mt-gd-1_34_1.lib' ExpEval * * *so I defined *BOOST_REGEX_NO_LIB *and ran the application this time I got the following error - *This application has failed to start because MSVCP80.dll was not found. Reinstalling the application may fix this problem.* Is any one faced the similar problem ? Please help me if you know whats wrong here. Appreciate your help in advance. thanks Srinivas

Exception handler of RHEL4 isn't working after the integration of Serialization code !!!
by Arunava Saha 11 Feb '08

11 Feb '08

Hi experts, After the integration of boost serialization code, the exception handler of RHEL4 isn't working at all. Do anyone of you encountered this? Or can you point to any potential mistake for which this can happen? This is quite urgent. Thanks, Arunava.

date_time with pre and post 2007 US time zones
by Michael Albert 10 Feb '08

10 Feb '08

Greetings! I would like to use boost::date_time to convert between U.S. time zones and GMT, with dates spanning the year-2007 change of rules. There is a "custom time zone", but that takes a Posix string which, if I understand correctly, can't handle both pre- and post-2007 simultaneously. I did see a dst_calc_engine, but there doesn't seem to be a way to connect that to a dst_day_calc_rule, at least not a method standardized in the library. Am I missing something? I guess I could just derive from dst_day_class_rule and override the start_rule_as_string() and stop_rule_as_string() to be something "random"? Thank you in advance. The Boost libraries really are wonderful. (Although I guess us users tend to only write when we hit a wall :-)). Thanks! -Mike

Boost.Serialization [For MPI] Crashes
by Aydin Buluc 10 Feb '08

10 Feb '08

Hi all, I have been using the serialization library since it is the way to go for communicating whole classes in Boost.MPI. Previously, I didn't have any problems. However, I now experience a strange problem. I have successfully ran all my code in SDSC's Teragrid cluster (A cluster of Itanium processors, running intel-linux), but when I tried to do the same thing in NCSA's cluster (which is similarly composed of Itaniums with same OS) I just can't build serialization library successfully. It says: intel-linux.link.dll bin.v2/libs/serialization/build/intel-linux/release/libboost_serialization-il-1_35.so.1.35.0 OBJREAD Error: Could not create mapping for "bin.v2/libs/serialization/build/intel-linux/release/basic_oarchive.o". icpc: error: problem during multi-file optimization compilation (code 1) Both clusters use the same kernel (2.4.21), same compiler suite (icc 9.1), same architecture, same mpixx (/usr/local/apps/mpich-gm-1.2.6..14b-intel-r2/bin/mpicxx). So, that was a little frustrating. But the fact is that, it creates the multithreaded library (libboost_serialization-il-mt-1_35) even after the error. I gave it a try. Compilation is flawless, but during runtime, main() is even not called [it seg faults immediately].When I debug it, I get the following backtrace: This GDB was configured as "ia64-suse-linux"... (gdb) run Starting program: /home/ac/aydinb/ParSPGEMM/testpar Program received signal SIGSEGV, Segmentation fault. 0x6000000000011ef0 in typeinfo for boost::serialization::detail::extended_type_info_typeid_0 () (gdb) bt #0 0x6000000000011ef0 in typeinfo for boost::serialization::detail::extended_type_info_typeid_0 () #1 0x4000000000103610 in boost::serialization::detail::extended_type_info_typeid_0::less_than(boost::serialization::extended_type_info const&) const (this=0x6000000000018650, rhs=@0x6000000000018910) at libs/serialization/src/extended_type_info_typeid.cpp:22 (gdb) I said fine. Maybe the library was broken due to errors in make / make install. Since we have the same settings, I copied the libraries from SDSC (which works perfectly). Same error, same lines from the gdb :( Any insight why this might be the case? Thanks, -- Aydin

Unresolved symbol in boost::filesystem lib with MS VC++ 2005 Pro
by Noud de Beijer 08 Feb '08

08 Feb '08

Hi all, I’m using boost version 1.34.1 (downloaded from http://www.boost-consulting.com/) with Visual C++ 2005 Professional. Everything worked fine (even boost::filesystem) until I started using boost::filesystem::directory_iterator. I’m trying to compile the example below and get a unresolved symbol: "unsigned int boost::filesystem::detail::not_found_error". *) Of course, I’m linking against the boost filesystem library (if I don’t I get even more unresolved symbols). *) I do define BOOST_ALL_NO_LIB but if I don’t I still get the unresolved symbol. *) Under Linux the same example compiles, links and runs fine! *) I checked and the symbol exists in the library. *) I’m using the correct runtime *) If I comment out the boost::filesystem::directory_iterator line (so only boost::filesystem::exists()) then the example compiles, links, and runs fine! Can anybody point me in the right direction? Is this a problem with my Visual Studio setup? Or is this a problem in the boost consulting stuff? Regards, Noud <code> #include "boost/filesystem.hpp" #include <string> int main() { std::string myDirString="C:\\"; boost::filesystem::exists(myDirString); boost::filesystem::directory_iterator myIter(myDirString); return 0; } </code ___________________________________________________________ Support the World Aids Awareness campaign this month with Yahoo!

Does boost have a float-to-integer conversion?
by linux＠celticblues.com 07 Feb '08

07 Feb '08

Does boost have a float-to-integer conversion? I need a routine to convert a 32 bit single precision float (1S 8E 23M) to integer, with the end goal being that I can take the integer break it down into bytes... i.e.bits 0-7, 8-15,16-23,24-31.
