C++ :: Can't Compile The Simplest Boost Asio Program
Feb 15, 2015
I can't compile the simplest boost asio program #include <boost/asio.hpp> int main(){}
Code Blocks 13.12 writes out message "swprintf was not declared in this scope". (within win_static_mutex.ipp file)
Visual Studio 2013 writes a lot more (within win_iocp_io_service.ip file), to begin with: "min is not a member of std" and there are a lot of errors in error.hpp file stating "WSA13 identificator is not defined" (WSA13, WSA100, WSA102 etc.)
Almost everything else from boost compiles good.

I am trying to initialize this chunk of code without it starting at the main menu in my state program:
boost::asio::io_service io_service;
tcp::resolver resolver(io_service);
tcp::resolver::query query(argv[1], argv[2]);
tcp::resolver::iterator iterator = resolver.resolve(query);
chat_client c(io_service, iterator);
boost::thread t(boost::bind(&boost::asio::io_service::run, &io_service));
char line[chat_message::max_body_length + 1];
This code came from a example at the boost example list: URL.....I want the networking to start when the multiplayer state initializes. This is how my program basically looks like:
//Main.cpp
main() {
if (!quit) {
while( handleing_events ) {
CurrentState->handleEvents();
[code].....
I tried to put the stuff in extern at states.h, and initialize it at Multiplayer(), but in handleEvents & ~Multiplayer, it says "c" is not defined...

What is the simplest 3D physics engine that you have used, that works well?
All I need to be able to represent is a spherical ground (planet), one or more tetrahedrons, with 1 or 0 cylinders coming out of each face, which might connect to other tetrahedrons. The tetrahedrons and cylinders have weight and can rotate around their connection point in 1 direction.
Basically, they are simple digital robots that need to walk around, so I don't need something with the complexity of Havok or Newton.

I have a input record like
acct|N|Y|N|N|rose@gmail.com
Now I need to create a logic to append a code to the end of the file using the following matrix rules.
00NNNN
01NNNY
02NNYN
03NNYY
04NYNN
05NYNY
06NYYN
07NYYY
[code].....
In the above example these four flags are "N|Y|N|N", so I need to append the matching code at the end of file "04".
desired output :
acct|N|Y|N|N|rose@gmail.com|04|
as it matches code '04':
04NYNN

I'm trying to write a program that uses the Boost library to input a string date in the format mm/dd/year and outputs to the string its corresponding day of the week. I wrote the program that I thought would accomplish this, but it doesn't seem to work. Below is the code I wrote:
#include <string>
#include <iostream>
#include "boost/date_time/gregorian/gregorian.hpp"
[Code]....
When I compile this using codeblocks it gives me the error "In function `ZN5boost9date_time19month_str_to_ushortINS_9gregorian10greg_monthEEEtRKSs':|
C:Users
osaDesktop est3........Liboost_1_55_0oostdate_timedate_parsing.hpp|67|undefined reference to `boost::gregorian::greg_month::get_month_map_ptr()'". And it takes me to the file date_parsing.hpp and highlights line 67. I don't understand why this isn't working.

My program needs to compile various source files at runtime.What is the most elegant way to compile cross platform with g++ from within my program? Is there a gcc-library I can use? I know that I could use popen() to open a Unix pipe and call g++ as command line tool. But first it isn't really cross platform and second it doesn't seem elegant to me.

I'm using ubuntu 14.04 and I want to cross compile this simple GTKmm program for Windows:
#include <gtkmm.h>

Gtk::ApplicationWindow window;
return app->run(window);
}
I don't know how to do this...When I use this command:

I'm trying to get my C program to compile but it's not working at all. I've programmed a little in C++ before but I'm not used to C. Here's my program so far:
Code:
int main(void){
// Establishes variables
int num1, num2, product;
float quotient;
[Code] .....
It keeps giving me an error message as follows:

I am currently learning OOP, and I can't figure out what the problem is with my header file. The rest of the program complies fine though. I am using g++ on UNIX.
myClass.h:9:23: error: Rectangle.h: No such file or directory
myClass.h: In function ‘int main()’:
myClass.h:13: error: ‘Rectangle’ was not declared in this scope
myClass.h:13: error: expected `;' before ‘rect’

Code:

#include "Rectangle.h"
using namespace std;
int main(){
Rectangle rect;
rect.displayMaxRectangles();
rect.process();

I wrote a program to run long simulations, in one cpu core computation. During the run, I checked the cpu occupation was always around 85%.
Since my simulation took time to run. How can I boost it up to make my cpu run at 100%? Is that because my RAM is not fast enough?
info about my laptop: cpu frequency: up to 3.2 GHz. RAM frequency: 1333 MHz.

I have in my main(), a function that creates my arg object using boost/program_options.hpp i want to pass this object to another function using templates like this:
Code:
template <typename Targ>
void Count(Targ & arg){
MyObj<string> QueryTab(arg["input-file"].as<string>()); //line number is 352
...
}
However I get an error:
Code:
../include/Filter.hpp: In member function ‘void Count(Targ&)’:
../include/Filter.hpp:352:40: error: expected primary-expression before ‘>’ token
../include/Filter.hpp:352:42: error: expected primary-expression before ‘)’ token
... obviously it does not recognize my intention, what did I do wrong?

I have an issue getting boost libraries to work with QT IDE. Here are relevant lines from my .pro file...
INCLUDEPATH += c:/users/bob/desktop/boost_1_53_0/
LIBS += -LC:c:/users/bob/desktop/boost_1_53_0/stage/lib64
After adding #include <boost/filesystem.hpp> I get error...
C:UsersobDesktopqtpuntitled5mainwindow.cpp:3: error: C1083: Cannot open include file: 'boost/filesystem.hpp': No such file or directory
The IDE does not highlight the line. The error only appears on compilation.

I have one problem deleting a file with boost. The file is opened in another application and cannot be deleted. I am supposed to received an exception error but I don't get it.
Here is my piece of code, very simple:
bool delete_file(const string &path) {
boost::filesystem::path bpath(path);
try {
if (boost::filesystem::remove(bath)) return true;
[Code] ....
I have put a breakpoint inside the catch part but it does not come to this point. Instead, the the output window of visual studio, I got these lines:
First-chance exception at 0x00007FFD2E575A88 in site_server.exe: Microsoft C++ exception: boost::filesystem::filesystem_error at memory location 0x00000070F8E3E920.

How to manage this situation?

i have written an algorithm in VC++ 2010 express edition. i have used the following header files
#include<iostream>
#include<string>
#include<sstream>
#include<ctime>
#include<cassert>
#include<fstream>
#include<vector>
[Code]...
the algorithm worked fine in vc 2010 express edition....
the following header files are not working in vc5
#include<regex>
#include<tuple>
#include<numeric>
#include<unordered_set>
#include "clip.h"
Looks like some of hte boost libraries have to added with vc5.. If any one knows how to add boost libraries with vc5.
showing lot of errors in vc5... not able to run the algorithm in vc5. Our company has only vc5.... the algorithm has to be implemented in vc 2010....

So I need to use boost/regex for regular expressions. someone told me that it needs to be built. the first problem is boost doesn't tell you how to build it and the second is i did sudo apt-get install libboost something. I don't remember the exact name of the package. it installed but i dont know how i would build it when its installed.

I have been using a Boost NonCopyable library in Microsoft Visual Studio 2013.
What I have is the following error message:
Error1error C2280: 'boost::noncopyable_::noncopyable::noncopyable(const boost::noncopyable_::noncopyable &)' : attempting to reference a deleted functionc:usersjohndocumentsvisual studio 2013projectsdonttreaddonttreaddonttread.cpp181DontTread
Now what I want to rectify the error is to throw an exception, so that the program can compile smoothly.

I have written a program that uses boost in visual studio 2012. The only boost library I used is filesystem by doing.
1)Properties->Linker->General and adding the path or the .lib to the additional dependencies. The libraries, link at compile time.However when i move the exe to a different computer, it doesn't work. Therefore the libraries were dynamically not statically linked. So my question is how do I statically link the filesystem library, so that i can include boost/filesystem.hpp in visual studio 2012?
