Error while trying to make library in code blocks

[puneetsardana88]

Hi

I tried to make a library using code blocks. For which I went file->new->project->static library and name it as mylib and then i created a file mylib1.c and mylib1.h (with some sample functions in it like Swap) and build them. Now I again make another project hello in which i make a file main.c in which I included lib1.h. When i tried to run the program i got the message "please select the host to run the library" something like that. Then i google it and then i went to project->build options->linker setting and then i add ..\mylib\libmyl ib.a. After that i got the error

lib1.h-No such file or directory.

What should i do?

Here is the code

For library

lib1.c

// The functions contained in this file are pretty dummy
// and are included only as a placeholder. Nevertheless,
// they *will* get included in the static library if you
// don't remove them :)
//
// Obviously, you 'll have to write yourself the super-duper
// functions to include in the resulting library...
// Also, it's not necessary to write every function in this file.
// Feel free to add more files in this project. They will be
// included in the resulting library.

// A function adding two integers and returning the result
int SampleAddInt(int i1, int i2)
{
    return i1 + i2;
}

// A function doing nothing ;)
void Swap(int *a , int *b)
{
    *a=*a+*b;
    *b=*a-*b;
    *a=*a-*b;
}

// A function always returning zero
int Increa(int x)
{
    return ++x;

    return 0;
}

lib1.h

void Swap(int *a , int *b);
int Increa(int x);
int SampleAddInt(int i1, int i2);

Then another project Hello i made main.c

#include <stdio.h>
#include <stdlib.h>
#include"lib1.h"
int main()
{
    int a=1,b=2;
    Swap(&a,&b);
    printf("%d  %d",a,b);
    return 0;
}

What should i do?I am using codeblocks with mingw under windows?

I have attached the screenshot also

Where is lib1.h located?

When you #include "lib1.h" it means that lib1.h is in the same directory as main.c OR lib1.h is in a directory that is along a pre-defined path.

When you #include <lib1.h>, it means that lib1.h is in a directory that is along a pre-defined path.

It looks like top need to pre-define a path. Go to your project settings for the preprocessor. It tis there you can specify additional directories for include files.

Coulnt find these options........ ....

Ok After 1 hours of searching and testing I have been able to execute it. Now the question is to the other party we only give header files. So how can I organize libraries

No you will need to supply them with the header and the .a file.

What do you mean how do you organise libraries? Just pass them over the other party can put them in a convenient directory and link them into their program.

Since you spent time figuring out the solution, why not share it?
