static library

CREATION OF STATIC LIBRARY

--------------------------------------------

The creation of static library is illustrated below with the help of different stages.

step1:

--------

vi file1.c /* The file to be called */

#include

void call()

{

printf("hai");

}

--> gcc -c file1.c

In this step,the object file of the code is obtained.

step 2:

--------

/*Header file which has prototype of file1.c*/

vi h1.h

void call();

--> ar rs libstat.a file1.o

The above command enables the object file generated in the previous stage

to be placed in the archiver.

step3:

-------

/*create "include" and "lib" folder(\home\student) */

note: create these folders in \home\student folder.

(a):copy h1.h file to include folder

(b):copy libstat.a to lib folder

step 4:

--------

vi program.c

#include

void main()

{

call();

return 0;

}

This is the application program making use of the static library.

step 5:

--------

gcc --static -I /home/student/include -L /home/student/lib -o program program.c -lstat

note -I stands for include and -L for lib and l for linking

Compiling the application code must be done using the above command

step 6:

-------

./program

Executing the application code
