C :: How To Include Single Header Files Into Project
Oct 2, 2014
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?
I'm trying to print a single linked list backward with functions/classes. I have created the main file and 3 header files. But I'm getting an error on one of the header files, linkedListIterator after adding #include "linkedListType.h". It says that "linkedLlistType.h" is calling itself. And when I try to run it, I get an error of "too many header files." I have tried changing the headers many times, but nothing seems to work.
.cpp file:
/*(Printing a single linked list backward) Include the functions reversePrint and recursiveReversePrint, as discussed in this chapter, in the class linkedListType. Also, write a program function to print a (single) linked list backward. (Use either the class unorderedLinkedList or the class orderedLinkedList to test your function.)*/
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 have started using code::blocks for practicing ,(was using bloodshed dev C++ til now). The thing is that m not able to compile multiple programs stored under a single project , as i have created project by the name of a topic and have decided to solve all problems related to that topic under that project.
When there was only one .cpp file in the project it compiled successfully ,but as soon as i created a second file and compiled it it says "main can be declared only once"
main.cpp Code: #include <iostream> using namespace std; int ReadNumber(); void WriteAnswer();
[Code] .....
The compiler complains: io.cpp||In function 'int ReadNumber()':| io.cpp|3|error: 'cin' was not declared in this scope| io.cpp||In function 'void WriteAnswer()':| io.cpp|7|error: 'cout' was not declared in this scope| io.cpp|7|error: 'endl' was not declared in this scope|
In io.cpp file, should I put the two statements ("include <iostream>" and "using namespace std") at the top, outside of the functions?
Or should I put the two statements inside each of the functions?
I have one requirement. I have a project lets Say baseProject.vcxproj. It has some header files. Another project lets say dependentProject.vcxproj loads baseProjects's dll and uses some of its header files.
When some other project lets say unrelatedProejct includes the header file from e dependentproject which includes baseproject's header file. It makes to change the include driectory setting of unrelatedproject. How to avoid this.?
I created a simple program that writes some text to two different text files. how to create a program that would retrieve the information from those two files, and put them in a single file, first the content of input1 and then the content of input2. how to do this. Here is the program that I created that creates the two files.
#include <iostream> #include <fstream> #include <string> int main() { using namespace std; string input1; ofstream fout("input1.txt");
I've tried to form together the following code so that I can process multiple files from one user specified directory. However, when I run the program it works great for the first file, but all other files are blank. The problem starts on the following line:
I have a piece of code in C with header files included. I run it on Mac OS X Maverick with XCode 4.6.2 installed. GCC is also installed. Note that Command Line Tools in XCode are already installed.
When I compile it, the error I receive says something like this:
add.c:1:19: error: stdio.h: No such file or directory add.c:2:20: error: stdlib.h: No such file or directory add.c:3:20: error: unistd.h: No such file or directory
However when I run it on Ubuntu, it compiles without a problem.What to do?
So I've been making a header file and put variables in their own namespace to avoid conflicts. My question is, do functions in the header file normally go in a namespace too, or should they just be named in a way which makes them unlikely to be accidentally copied?
My teacher talks about header files just having definitions and not declerations. I am writing a program that has a .h file and a related .cpp file along with a main.cpp it would be nice to have the .cpp file associated with the .h file compiled into an object file that would than just be referenced when the .h file is included. Am I making any sense?
I want to use two header files in my program. Here is exactly what I want to do.
-In the first header I have a binary tree and a structure. -In the second file I have another functions that need to use the structure in the first header. -I also want to use a function from the second header in the first. -And finally I want to do actions with both headers in a "main.cpp" file that contains only int main() function.
How to include the headers in each other and in the main.cpp to be able to do the actions above?
I try to include the first header in the second one and the second one in the first header. Then I include both headers in the main.cpp file. But the compiler shows me many errors.
I'm working with CGAL - Computational Geometry Algorithms Library, which is a library of geometry functions declared as several thousand header-only files. When I run a basic program (source code [URL] ) I get this output: [URL]
I have tried switching angle brackets to quotes. I have also started reading up on CMake.
Do I need to walk the dependency tree and add all of those files to my CMakeLists.txt? Or is there a way to tell the compiler to look in subdirectories?
I have some header files with generic functions. And in one of them, I define TRUE and FALSE. Recently I started using another header file and it defined TRUE and FALSE as well. That caused GCC to throw an error, and not compile. In my case I can put #IFNDEF around the values so that if it is already defined they don't get defined again, but is there a better way to handle duplicate names? I assume the case would be the same for duplicated functions, how does that get handled?
I have a problem with making header files in c, i get the code written only in main.c and then i have to create a files with extension .h and extension .c but how to do it.
So say I create a header file which contains a list of structs, and I want to use these structs through out my source and some of my classes... how would I accomplish this?
When I try to do it via #include, I get re-definition errors, due to the nature of #pragma once. If I switch to #ifndef then I lack defenitions in files other than the source.
Is there a way to define things such as structs across multiple files, which doesn't lead to re-definition errors, and doesn't involve manually re-created all the structs for each file?
I'm having with header files, specifically to do with the string data type. The objects work perfectly when I put them inside the .cpp but when I set it to include the exact same code in a .h, I get a string of error messages.
