creating an nmrl archive library - 2

• Have our main program in hwcgimain.c call an external:

#include <stdio.h>

extern void helloworld(void);

main()

{

printf("Content-type: text/plain\n\n");

helloworld();

}

shell/iX> gcc -c -D_POSIX_SOURCE hwcgimain.c

• Link the program:

shell/iX> gcc -o hwcgi hwcgimain.o -L. -lhw

shell/iX> ld -o hwcgi hwcgimain.o -L. -lhw

• -L. specifies library search directory (. is CWD)

• -lhw refers to libhw.a
