Creating an Archive Library - 2

• Have our main program:

> cat > hwcgimain.c
#include <stdio.h>

extern void helloworld(void);

main()
{
  printf("Content-type: text/plain\n\n");
  helloworld();
}
> c89 -c -D_POSIX_SOURCE hwcgimain.c   

• Link the program:

> c89 -o hwcgi hwcgimain.o -L. -lhw     

-L switch specifies library location (. is CWD)
