Jan 3, 2014I've recently integrated a scripting functionality into my game engine (squirrel), but I can't figure out how to dynamically link the library.I have to dynamically link some libraries for licencing sake, but I'm forced to statically link Squirrel. How can I statically link Squirrel, but dynamically link the others?

May 8, 2012i'm iterating through the system processes an when i find a process that belongs to a text oriented application, i want to read that text inside the external app. For example, when i get the process to an instance of notepad, i want to get the text contained inside notepad. i've tried to do it using Process.MainWindowHandle pointer, but with no success. How to do it? (This is for an "nanny" app i'm writing, which need access to text in external applications so that i can detect any unappropriated words)

C++ :: Accessing Symbols In Application From Within Dynamic Library MinGW
Apr 17, 2013I am porting an application from Linux to Windows. Since it is a GTK app most of the stuff works; I have to touch a little here and there. One problem though I cannot find the solution as it seems. The application uses a plugin system for easy expandable functionality. The interface to the plugin is very simple: an init function, a worker function, and a deinit function. The plugins shall have access to the main applicationsymbols (functions global variables). I cannot find a working (and feasible) way under Windows to make the linking work. I always get "undefined reference" errors for symbols which exist in the application. I am using MinGW 4.6.2. I made a stripped down demo application to be able to better (and faster) test the principle. I am using the dlfcn-win32 project from Ramiro Polla [URL]... for the dynamic loading stuff and it works like a charm.
Here is the project:
plugintest.tar.gz
plugintest.zip
It tried a number of commandline options to the linker for the application (--export-all-symbols, --export-dynamic, -rdynamic (apparently not supported in MinGW)) as well as for the shared objects (--allow-shlib-undefined, --enable-auto-import, --enable-runtime-pseudo-reloc).
As you can see in the provided makefile under Linux it is just "-shared" for the .so. Under Mac OS X (Darwin) it is "-bundle -bundle_loader <app name>".
Either it is a different configuration / environment or I must have overlooked something. How to do this and if it is even possible in Windows?
Here is a .zip archive of the dlfcn stuff with modified makefile, which works on the cmd.exe command prompt; MSYS is not required. Just adjust the MinGW installation path in config.mak and type 'make" and 'make install'. dlfcn-win32-r19.zip
C++ :: Application That Has One Static Library Dependency - Linking Error
Feb 16, 2012I am trying to build an application that has one static library dependency, however I am getting this error when linking:
1>ClCompile:
1> All outputs are up-to-date.
1>LINK : fatal error LNK1104: cannot open file 'TestWrapperLib.obj'
Why I might be getting that? I have the .lib in the depends line, and the directory where it is at in the include line.

View 2 Replies View RelatedC# :: How To Start Application And Automatically Pass Input To That Application
May 9, 2012I want to create an application that starts an application and passes input to that application. I know how to start a process using the classes in System.Diagnostics, but I don't know how to pass data to the process.
For example, and this is just an example, I would like to be able to automatically start an application that requires a username and password and automatically enter the username and password. Of course, that might open the door to security vulnerabilities, but that's not the point of the exercise.
How to implement the functionality I described? Is there a general way to go about doing this or does it depend entirely on the idiosyncrasies of the application in question?
C++ :: Shared Library Vs Static Library?
Jan 17, 2014I've been reading about libraries; How to make them, how to use them, the different types of libraries, etc..
When using a shared library, does the program require that library to be installed on the computer after the program has been compiled into an .exe?
Ie.. if somebody downloaded a "Helloworld.exe" that I had compiled on my computer using a shared library (that wasn't part of a standard operating system), would they also need that shared library on their computer for the program to run without errors?
and for Static Libraries, when I compile a program using a static library, does it include in the final binary only the functions of the library that are actually used, or does the compiler add in the entire library?

how to link the case 2 to days and case 3 to months?

C/C++ :: How To Link Elements Of Array
Mar 15, 2012I am trying to take the Array v[]={0,1,2,3,4,5,6,7,8,9} and put some of the numbers together so I can create a math problem. I have used next_permutation to get the possible combinations of the numbers. I am trying to check every combination to see if they work. Like v[1]v[2]v[4]v[0]v[3] to get then number 12403 (that is where I am having the problem) that I can subtract from v[7]v[2]v[0]v[1]= 7201 to get the answer 5202. How can you put v[1]v[2]v[4]v[0]v[3] together to get the number 12403?

Feb 16, 2015I'm getting a massive 1300 char link error with VC10. It appears to complain that it can't see the constructor although the constructor is definitely there.
Error:
test_GatewayNS.obj : error LNK2019: unresolved external symbol "public: void __thiscall std::allocator<class BinarySearchVector::ElementTemplate<class Gateway,unsigned __int64> *>::construct(class BinarySearchVector::ElementTemplate<class Gateway,unsigned __int64> * *,class BinarySearchVector::ElementTemplate<class Gateway,unsigned __int64> * const &)"
[Code] ....
However, the constructors seem to be there and if I copy them into my program just to make sure - the compiler complains that they are already defined:
namespace BinarySearchVector {
template <class ElementType, class IdType> class ElementTemplate //allows comparison functions to be redefined {
public:
ElementTemplate(IdType myId) : id(myId), tickCount(0), requestingDeletion(false) {};

Any clues as to what I'm missing ?

C++ :: MinGW And Export Link Libs?
Jan 5, 2012I'm building an app using VC++. The app links to a DLL built using TDM-GCC (which uses MinGW I think). Obviously, the DLL comes with a link lib.
If the lib is linked to another MinGW app, the DLL functions get found by name. So if the DLL builder updates his DLL, the MinGW app carries on working.
However, if the same lib is linked to a VC++ app, the functions get found by ordinal value. But MinGW doesn't seem to have any means of guaranteeing that a later build of the DLL will use the same numbering scheme. So his new DLL will break the pre-existing VC++ app that used it.
In VC++ this problem could be solved by using a DEF file but that doesn't seem to work in MinGW. So my question is:- can a DLL built with MinGW be somehow instructed to export its functions only by name - or at least to export them so that any other compiler will import them by name and not by ordinal numbers?
C++ :: Link Between (STL) Container And (Fstream) File I/O?
Nov 9, 2012I did some of the projects using STL container and it is pretty much efficient to retrieve the data's information quickly (i.e. sets, sets & maps). I read many C++ OOP book and none of them make me clear about the Link Between (STL) Container and (Fstream) File I/O. Can they link together ?
I am going to design a small Library Book Management Project. I am planning to develop it using the STL Algorithms & containers. Objective of this project is to keeping the records of books issued and deposited by students in a particular date. User will be given a facility to retrieve student's information, book information and he/she can modify/update specific book's, student's information by changing issue date, deposited date, Book's publication etc.
My intention is to create a File I/O where user can input & update/modify daily transaction inside the file called (xx.dat) file in project directory. Is it possible to create 'set' container inside the file (xx.dat) ? Or, It's impossible ? Or, do i have to do this in other way?
