Static Shared Library in C - Linux
1. Create a C file with a function - example :
#include "stdio.h"
int addnumbers(int a , int b)
{
int total;
total = a + b;
return total;
}
2. The next step is to complile this file :
gcc -c moo.c
3. Use the ar (man ar - create, modify and execute from achives)
ar -cvq libmoo.a moo.o
4. The libmoo.a static library will be created.
5. Display the symbols for the object files for libmoo.a with
nm libmoo.a
6. Use the ranlib libmoo.a - for run the library
7. Now create the main program - foo.c that will use the static library
#include "stdio.h"
#include "iostream.h"
#include "string.h"
using namespace std;
//declare the function inside the program
int addnumbers(int a , int b);
int main()
{
int total = addnumbers(4,10);
printf("the sum is : %d", total);
return 0;
}
8. Compile the main program using the static library libmoo.a
gcc -o foo foo.c libmoo.a
9. Run the program to check if all are OK :
./foo ---> // that will display the sum is : 14 if all are OK
