I have been trying to compile a static version of the boost libraries, however when I try to launch the program it says fatal error LNK1104: cannot open file 'libboost_serialization-vc100-mt-s-1_53.lib'
I have checked in the boost/stage/lib folder and that file is not there. I compiled boost with b2 link=static yet the file still isn't there.
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 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....
I'm currently working on a Microsoft (unmanaged) C++ project which utilizes Boost C++ libraries. It's been quite a while since I've done C++ and I have no previous experience using the Boost libraries.
We are using Boost 1.55 and MSVC 2013. We used CMake to generate the Visual Studio solutions and projects based on the original project layout.
We've successfully built and tested on other environments. In the MSVC - Windows environment, we've run into issues using Boost's Property Tree support. Specifically, the issue seem to center around trying to put properties into PTNodes.
Consider the following code snippet:
void XXX:: SomeFunction() {
PTnode ptNode;
ptNode(Mapper::KEY_INPUT, Tracer::SOME_VALUE);
ptNode(Mapper::KEY_OUTPUT)(Tracer::SOME_OTHER_VALUE, Tracer::ADDITIONAL_VALUE);
SetResults(ptNode);
[Code] ....
This work around seems insert the nodes successfully into the tree.
We are able to verify by finding the inserted items in ::SetResult().
Why this might be failing in VisualStudio C++?
Is this an issue of compiler flags?
precompiler definitions?
Linker options??
Memory mode/model??
Are there some basic behaviour differences in MSVC C++ and other C++ environments which we are unaware of?
I've tried to identify all instances of the node insert pattern and use the work around. But, we really need to find out what the issue is (as there could be other manifestations).
Later i used trial version of vc2010 and created a static library using the below link. Its worked. [URL] .....
But now I'm using VC2003.Details as follows,

I used the same procedure & created the Static lib. But couldn't use this lib file in my main project.B'cos the project's property window doesn't have the :

Couldn't find. Here with i attached missed property in VC2003. How can i set this property? Is any other way to use static lib in main project (application)?
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?
From my book:
"A static function might have this prototype:
static void Afunction(int n);
A static function can be called in relation to a particular object by a statement such as the following:
aBox.Afunction(10);
The function has no access to the non-static members of aBox. The same function could also be called without reference to an object. In this case, the statement would be:
CBox::Afunction(10);
where CBox is the class name. Using the class name and the scope resolution operator tells the compiler to which class Afunction() belongs."
Why exactly cant Afunction access non-static members?
What are the workarounds for accessing the non-static member variables of some class(Say A) inside static member functions of another class(Say B)? I am coding in c++. Class A is derived with public properties of class B. Any pointers?

My question according to what i just wrote:
1. Is that mean that Do() is only available for use by Dog itself because Dog is 'oryginal' Dog, and if i create new dogs - instances of oryginal Dog (dog1, dog2 ...) they cant access because Do is only available fo 'oryginal' one? Is that correct thinking?
2. If i would want to have something common (e.g value) for all dogs is that good way to create static field/method for Dog instead of non-static once then all instances of Dog would access Dog static member to get/change it? Just stupid example: static method GetAmountOfLegs() which return 4 Then all instances can take/call that value from Dog. Is that correct thinking?

Is there any code I can use to determine my compiler version and which Standard It uses? I know the following code determine that my compiler followed ANSI But how about a version of that? ****My OS is now Ubuntu
Code:

printf("File :%s

return 0;

Is there any way to add version number when build a file so the version is added in the properties.
I doing this in a MFC c++ project in a .rc file. Is there a way (or a similar way) of doing this in C? Here its stored in the details section with product version 6.0.8:

When you are creating a project or program, how do you number your versions?
Like when you release it, it becomes v1.0, am i right?
then every release or build after that might become v1.1 or v1.0001 or v1.0.1.2
Is there a certain global system for how you Number your versions or is it just up to the developer?
I'd like to use the Big Integer Library [URL], but I have issues to use it. I'm using Xcode as compiler and I don't know how to include the library in my project files. When I drag all the files in the project directory and write the statement #include <BigInteger.hh> on the top of the declaration of the main function, even whiteout any other code, I get lots of build error on the .hh and .cc file.
how to include the library on my project.
I have written library in c++ for c++ application. Here, data exchange between library and client through structure. This structure has 20 members ( strings, integers, reals, pointers).
In some flows, library needs few members should get filled in the structure. for ex, application filled 3 integers information and passed to structure. But, in memory, whole structure is occupied.
I think, If library provides functions for every combination, then it would end up with lot of functions. I want to avoid that.
How to optimize data exchange between client and library? ( number of members may be filled sometimes 1, 2, 3, .. 20)

I have a set of projects. Each one builds either a static library or an executable. What I'd like to do, is at build time I want to embed a version string representing the version of the executable as well as the version of each library. These version strings will come from an external source (in my case it's based on a "git describe" call, but that's beside the point). Embedding such strings can be highly valuable for traceability. (Versions of 3rd-party libraries are not necessary.)
I'm using qmake as my build system, but this should work more or less similarly with any build tool. What I'd ideally like to do is define this process in such a self-contained way that a an absolutely minimal amount of additional code is required in order to leverage it. Preferably, nothing more than an include(version.pri) in each project's .pro file in order to collect the versions. (Retrieving them later, such as to respond to a --version command-line flag, can be done via traditional C++ methods.)
What I've done so far is to define a singleton VersionTracker class, and then tweak the build system so that "MODULE" and "VERSION" are preprocessor symbols defined at build time. I've also tweaked the build system so that a file in each project, version.cpp, is rebuilt (and regenerated if necessary) on every build regardless of changes. This source file can capture the information in the preprocessor symbols into each static library and the executable.
Now, here's the problem. How can I get the information from those version.cpp files into the VersionTracker class? I thought I could use a global object's constructor to do it, but it turns out the symbols are stripped out when the static libraries are linked so I only get the executable's version. I also found a page on stackoverflow detailing a very clever way to call a registration function at class definition time, but again the class definition appears to be stripped out if it's defined in the version.cpp file of a static library and not referenced elsewhere.
Everything I've read basically says you either need to use linker flags to prevent symbol stripping entirely, which is probably an adoption-killer for this hack, or you need to use an explicit registration function called from the executable. I'd prefer to avoid this since it is just another thing a programmer could forget to update when a library dependency is added or removed.
My last idea, which I haven't tried yet, would be to put each version.cpp into a separate static library from the one it is describing. This version-only library could be linked without symbol stripping. I don't love this concept but it might work.
I haven't yet figured out how shared libraries can be worked into this framework at all. I'll worry about that after I get static libraries working.
Is there a way I can extract Machine / Hardware ID and OS Version using VC++?
View 3 Replies View RelatedIs there any way to do date math using standard C libraries? I looked around in the time.h but didn't see what I needed.
What I need to do is be able to add a certain number of minutes to a date and have it give the current date/time. For example, add 15918765 minutes to 01/01/1980 00:00 and have it tell me 04/07/2010 4:45PM. I really don't want to write this myself or go platform-specific.
Does this exist somewhere or am I SOL?
I know I can use -isystem path to mark a path as containing system headers which shouldn't be included when generating warnings, and this works, but it doesn't work when the warnings are generated by instantiating templates from the library in my source code. Is there any way to ignore these template-instantiation-generated warnings too?

There are many libraries in C++, but how are they made?
For example: SDL, SFML, Open CV, STK
There are no special functions in C++ from which we can create such libraries, If I wanted to create a library that processes sound signals, how would I do that? How can I access the mic, speakers and process the signals.
Open CV processes videos but which functions does it use?
I want to write a small game library that uses GLFW.
So I have for example a window class that uses GLFW functions.
To do that my window class must include the GLFW header files.But I don't want, that if I use my library later and I include my window class, that all GLFW functions are included, too.
How I can prevent this and hide GLFW from users of this library completely, so they theoretical don't notice that this library use GLFW ?
And a second question, is it possible, if I export my game library statically that the GLFW lib files are hidden in my own lib files, so that I have finally only one lib file that is needed to use my library ?
