wave: changing to relative paths in #line output?
by Paul Johnson 25 Mar '10

25 Mar '10

I'm evaluating wave as a cpp replacement. I'm having a problem at the moment in that the #line output shows the name of the source file as an absolute path, and my regressions are expecting a gcc-style relative path. Before I have a go at hacking this, can anyone tell me if there's some configuration that can be set to output relative paths? Or to make the output more gcc/cpp-compatible? There are a couple of other minor differences to gcc and mcpp: wave produces '#line n', for example, and the others produce '# n'. Thanks - Paul

alignment error with make_shared?
by Kenny Riddile 24 Mar '10

24 Mar '10

m_meshes is a std::vector< boost::shared_ptr<const Mesh> > in the code below, and Mesh is constructible from a const std::string& BOOST_FOREACH( const std::string& fileName, meshFiles ) { m_meshes.push_back( boost::make_shared<Mesh>(fileName) ); } Using make_shared here gives me the following error, while explicitly constructing a shared_ptr does not. Mesh isn't defined with __declspec(align('16')), but I believe it owns a member that is. Am I doing something wrong or is this a known limitation of make_shared? Also, I am using MSVC9 if that wasn't obvious. 1>C:\Work\redshirt\third_party\boost\1_42_0\boost/smart_ptr/detail/sp_counted_impl.hpp(138) : error C2719: 'd': formal parameter with

Boost static linking
by Alex Farber 24 Mar '10

24 Mar '10

I am using the Boost library with g++ on Linux. When I built this library, I executed this command: ./bjam (without parameters). My lib directory looks like this: libboost_thread.a libboost_thread.so libboost_thread.so.1.41.0 ... Building the project using Thread library, I added boost_thread to the linker dependencies list. Now my program depends on the shared library libboost_thread.so.1.41.0. For my purposes, I need to make static linking, to exclude runtime dependency. How can I do this? -- View this message in context: http://old.nabble.com/Boost-static-linking-tp27714367p27714367.html Sent from the Boost - Users mailing list archive at Nabble.com.

error in boost_serialization of static variable
by ashish srivastava 24 Mar '10

24 Mar '10

Hello I am having some problem in executing the code of boost_serialization. I'm trying to serialize the static class member variable. For that purpose I have wrapped the int static variable to tracked_int static variable. Please find the code attached with this mail. This is how I'm running the code and getting the segmentation fault. --------------------------------------------------------- $ g++ test_serialization_linklist.cpp -l boost_serialization $ ./a.out do u want to continue adding more nodes into the link list (y/n) ??y do u want to continue adding more nodes into the link list (y/n) ??y do u want to continue adding more nodes into the link list (y/n) ??n 5 6 6 6 the number of nodes present in the list = 4 Segmentation fault ----------------------------------------------------------------------------- The INTERNET now has a personality.

boost::thread SIGABRT when starting thread?
by Sean McAllister 24 Mar '10

24 Mar '10

So I'm trying to get some throughput measurements on an I/O library I'm working on, and I'm currently testing a synchronous mode so that I need two threads, one to read data and one to write. The code is quite simple: template <typename T> void sync_read_loop(pf_istream *in_sock, T *buffer, uint32_t iters) { for (int ii=0; ii < iters; ii++) { (*in_sock) >> buffer; } } template <typename T> void sync_write_loop(pf_ostream *out_sock, T *buffer, uint32_t iters) { for (int ii=0; ii < iters; ii++) { (*out_sock) << buffer; } } template <typename T> void TEST_READ_WRITE(const char* msg, t_pf_type pf_type, bool &all_passed, T (*randnum)(), bool throughput, bool sync) { const size_t BUFF_SIZE = 1024*1024; const size_t ITERS = 32; T* write_buffer = (T*)(new char[BUFF_SIZE*sizeof(T)]); T* read_buffer = (T*)(new char[BUFF_SIZE*sizeof(T)]); if (sync) {

BoostTest: Is BOOST_MESSAGE is not thread safe?

Guys, I've just noticed BOOST_MESSAGE is not thread safe instruction. It is unbelievable!! I do not want to believe it!!! Try this: #define BOOST_TEST_MAIN #include <boost/test/unit_test.hpp> #include <boost/thread/thread.hpp> void foo() { for( size_t i = 0; i < 100000000; ++i ) { BOOST_MESSAGE( "111111122222222223333333333" ); } } BOOST_AUTO_TEST_CASE( testBoost ) { size_t const SIZE = 2; boost::thread t[ SIZE ]; for( size_t i = 0; i < SIZE; ++i ) { t[ i ] = boost::thread( &foo ); } for( size_t i = 0; i < SIZE; ++i ) { t[ i ].join(); } } windows XP SP3 32bit VS 2008 SP1 boost 1.42 -- Dmytro Ovdiienko

Linking with Boost on x64
by Iskandar Prins 24 Mar '10

24 Mar '10

Hi all, I have build the bjam tool and then I run the following: bjam toolset=sun stdlib=sun-stlport address-model=64 stage When I try to link with the generated libboost_thread.so I get the following error: ld: fatal: file <my_path>/libboost_thread.so: wrong ELF class: ELFCLASS64 Does this mean that the libraries are compiled for 32bit instead of 64bit? And how can I fix this? Regards, Iskandar
