I've downloaded a file that I need to include in a new project. It's called phidget21.h and it's sat on my desktop. I've tried copying it to lots of various places. But I still can't get a new source file to compile. I think I haven't copied it to the right place yet. Where should I have copied it to?
I'm a beginner with C and wonder how to include single header files (*.h) in to my project. I mean header files which are not included to the standard installation package.
I thought it would work if I just copy the newheader.h file in to library folder c:MinGWinclude, but it didn't work. Is there some kinf of GCC -command or procedure to add these single header files or how it should work?
All of those standard header files are working well and I don't have any problems with them.
if I include iostream twice in my project why is that valid? Wouldn't the linker see that there are two definitions of it and report a error, but it works?
Basically, I have made a program which implements the platform specific layers (such as entry function, file loading, timing functions etc.) that gets compiled into a .exe (or platform equivalent).
But I want to make this portable and reusable across other projects, so the entry function for the platform will call the function "AppMain" which is the generic main function that is not reliant on the underlying platform etc. (i.e defined in a .h file that the project module will implement).
Ideally I would want to build the AppMain code into its own library. However, This AppMain code would want access to the Platform functions such as the functions compiled into the .exe.
This has confused me somewhat and has forced me to build both the AppMain module and the Platform Code into the same exe file so they can use each others functions.
Is there any way I can create a header file (with all the function prototypes in) but they do not get implemented in the Platform code but rather they can be 'guaranteed' to be available at runtime?
Here is what I am trying to achieve in a high level view:
win32layer.cpp: (implements all the functions defined in Platform.h)
in this scenario of course I could not compile the platform functions as the application has not been created and thus appmain cannot call the platform functions because that has not been created etc....
my programme showing error 'unable to open inclde file ****' i fallowed the general procedure i.e., options-->directories--> ( inclde proper path) still not working..
I have four source files. The main source file includes two other source files. The two other source files both include the fourth source file. In the fourth source file I have an include guard. Will the code from the fourth source file exist in two locations in the compiled code? Is this something that is compiler dependent? An example of this is shown in the code below.
I get the following error in XCode whenever I try to access the member I created 'randomGen' in a separate class in a different header file. I have made sure to include the header file and have tried to access it through an object.
This is the code I enter when trying to access the method from randomiser.h in main.cpp. It is also an overloaded function with doubles and integers:
RandomG randomiser; randomiser.randomGen(); // 'Call to member function 'randomGen' is ambiguous'
This is the code inside randomiser.h:
#include <string> #include <iostream> using std::string; using std::cout; using std::endl; class RandomG {
[Code] ....
This is the error inside xcode: [URL] ....
I have tried seperating the code for the functions in another class (main.cpp) and then running and it seems to works, so I'm not sure why I can't put everything in the .h file and then access it?
I would like it in a seperate file so it doesn't clutter my main. I am writing a game with SDL so that might be confusing and I would like the window to have a random title and other random properties, so it would be easier to use a function.
I have written my program and it works when I keep everything in the header files, and then have my main. I am now splitting them up into implementation files, but Eclipse keeps giving me errors. It gives me error at every opening brace of the constructor and functions. It says on all of them "Redefinition of (name of constructor or method), Previously declared here." What am I doing wrong, because it works in the header file?
I wanted to share the value of a variable from Sender Program to Receive after program and want to calculate difference between send and receive. After studying Header file concept I program following three.
Now I am struck. How to to compile? I link all these file. I used following method:
Then I run Sender and after that Receiver.I per my knowledge, Receiver should give difference but it gives error :
Code: Receiver.c: In function "main": Receiver.c:10:42: error: "Send" undeclared (first use in this function) printf(" Total Receive is %d ",Receive-Send);
Code: Sender.c #include <stdio.h> int Send ; void main(){
I have been working a project in C++. I have TTTMain.cpp file that has all the function calls, TTTFuntions.cpp that has all the functions, I have TTT.h file that has all the prototypes and variables and additionally I have Winner.h that has enum class Winner declaration in it. Here is my block of codes:
Winner.h file:
#ifndef winner #define winner enum class Winner {
[Code]....
My question is when I compile this gives me error on
I made my header file. If cpp file with definitions is in project compiler knows it has to be linked, but if it's not compiler doesn't know. If I include standard library or boost I don't have to manually link cpps. How to do so including my header automatically links cpp? Maybe problem is with something else?I use VS 2013.
My socket.cpp program got error. it showed "socket.h: no such file or directory". I had put my header file (socket.h) in the same place with my source file.
