Thread: Linker error when compiling Qt program

Hi,

I am getting linker errors when i compile 3 modules as given below

The module layout is as below

Code:

Z.h
{
int s;
void B();
}

Z.c
{
int s = 1;
void B() {
statements;
}
}

Y.c{
A() {
if (s)
B(); }

X.cpp{
extern int s;
s=0;
A();
}

Rules for compilation :

Z : Y Z.h
cc -o Z Y

Y.o : Z.h Y.c
cc -c -o Y.o Y.c

Z : Z.h Z.c
cc -c -o Z.c

Y : Y.o Z
cc -o Y Y.o Z

I get a linker error when i compile the modules as follows
/usr/lib/gcc-lib/i386-redhat-linux/3.2.2/../../../crt1.o(.text+0x1: In functi
n `_start':
../sysdeps/i386/elf/start.S:77: undefined reference to `main'
