I want to iterate over all files in a directory matching something like "somefiles*.txt". Does boost::filesystem have something built in to do that, or do I need a regex or something against each leaf()? ...
My application converts past and present dates from local time to UTC. I need to ensure I will honor any future DST updates to Windows while still correctly handling past dates. The application is written in C++ and is running on Server 2003. Options I've researched: gmtime() and localtime() are not always correct for past dates bec...
Hello experts I have been trying to emulate a copy_if by the following codes but my compiler (g++-4.0) just keeps complaining. What's technically wrong? Thanks for your help! template <class STL> // a std container of class A, but I don't know if it's a list or vector or deque void export_(STL& Alist) { //a member function for_each(Al...
BOOST_FOREACH is really neat, but the C macro style of writing is somewhat off-putting. Is there a trick to avoid the all-caps spelling? ...
I just started using Boost::regex today and am quite a novice in Regular Expressions too. I have been using "The Regulator" and Expresso to test my regex and seem satisfied with what I see there, but transferring that regex to boost, does not seem to do what I want it to do. Any pointers to help me a solution would be most welcome. As a ...
I have a simple struct : struct MyType { std::string name; std::string description; } and I'm putting it in a shared memory : managed_shared_memory sharedMemory(open_or_create, "name", 65535); MyType* pType = sharedMemory.construct<MyType>("myType")(); // ... setting pType members ... If the two applications communicating w...
I have a situation where a boost::function and boost::bind (actually a std::tr1::function and bind) are being deleted while still in use. Is this safe? I would normally avoid it, but the offending code is a bit entrenched and my only other option is adding a new thread. typedef function<int(int)> foo_type; foo_type* global_foo = NULL...
I have three legacy applications that share a lot of source code and data. Multiple instances of each of these applications be executed by a user at any time, e.g. a dozen mixed application executions can be active at a time. These applications currently communicate through shared memory and messaging techniques so that they can maintain...
I am using BOOST_FOREACH to iterate through the characters of a C++ string like this: void foobar(const string& str) { BOOST_FOREACH(const char ch, str) { // Do something with ch } return; } This piece of code works fine with the following compilation modes: Multi-threaded (Release) (/MT) Multi-threaded Debu...
Hi, I'm trying to set up a timer using the boost library. Basically, this is what I wrote: class ContactList { public: ContactList(); virtual ~ContactList(); int Start(); int readFromFile(); int dumpList(); void checkContacts(const boost::system::error_code& error); void initializeTimer(); private: std...
What is the difference between Boost::bind and Boost Phoenix::bind? ...
I'm trying to use Boost::bind and std::copy to print out the values in a list of lists. Obviously, I could use loops, and I may end up doing so for clarity, but I'd still like to know what I'm doing wrong here. Here is the distilled version of my code: #include <boost/bind.hpp> #include <iterator> #include <algorithm> #include <list> ...
I'm using phoenix::bind and receiving this error message: error C2039: 'bind' : is not a member of 'phoenix' The code line where I'm using bind and where the error is pointing is: phoenix::bind( &OptionalInputPort::eraseDataEditor ) ( phoenix::var( *optionalPort ) ) and I can't figure out what is the pro...
I'm getting a lot of errors compiling code using the boost libraries, mainly when I'm using Spirit namespace. The errors are syntax errors on boost files like: boost/spirit/home/classic/dynamic/lazy.hpp(33) : error C2143: syntax error : missing ';' before '<' or boost/spirit/home/classic/dynamic/lazy.hpp(33) : error C4430: miss...
Is there a non-hacky (i.e. no assembly, ...) way to use boost functions to create callbacks with non-static class methods? Currently for static methods: list<function<void (LuaState&)> > _callbacks; I was thinking something along the lines of list<tuple<function<void (void *, LuaState&)>, void*> _callbacks; but boost functions doe...
UPDATE: Found a way to make it compile, see below. Hello, I'm having issues compiling boost programs under cygwin. I've installed the default boost and g++ packages from the cygwin project's setup.exe. On my Linux systems, I can compile a program reg.cpp using the following: g++ -I/usr/include/boost -lboost_regex -o reg reg.cpp On c...
Hi, I am trying to run blocking_udp_echo_server.cpp from Boost asio example on MacOSX 10.5. But it crashes: From the console: /Developer/SDKs/MacOSX10.5.sdk/usr/include/c++/4.0.0/debug/safe_iterator.h:127: error: attempt to copy-construct an iterator from a singular iterator.

Hello everyone. For some reason, I cannot get ptr_list to insert elements. boost::ptr_list<int> somelist; int *someint = new int(123); int *someint2 = new int(456); somelist.push_back(someint); boost:: ptr_list<int>::iterator i = somelist.begin(); somelist.insert(i,someint2); Any help, please? ...
I have to update an application to use Boost 1.34 instead of 1.37, and it's causing me a ton of trouble. One of the biggest problems at the moment is that I don't know Boost threads very well. With 1.34, I get... error C2039: 'this_thread' : is not a member of 'boost' ...for the code boost::this_thread::sleep(boost::posix_time::mill...
