Hi all,

i wrote one code like this

File1.c

_____________________________________________

void f1() {
printf("From f1()\n"
}

int main() {
printf("Frim main() File1.c\n"
f1();
f2();
}
_____________________________________________


File2.c

_____________________________________________

void f2() {
printf("From f1()\n"
}

int main() {
printf("Frim main() File2.c\n"
f1();
f2();
}
_____________________________________________


As you can guess at the time of compilation i am getting
the error main muliple define.

Is it any way to add some directive in the code to make
two different exe, one from file1 and one from file2.

I don't want to change the code for each compilation.


Regards,
Amar

File1.c

_____________________________________________

void f1() {
printf("From f1()\n"
}

#ifdef _USE_FILE1_MAIN_

int main() {
printf("Frim main() File1.c\n"
f1();
f2();
}

#endif
_____________________________________________


File2.c

_____________________________________________

void f2() {
printf("From f1()\n"
}

#ifndef _USE_FILE1_MAIN_
int main() {
printf("Frim main() File2.c\n"
f1();
f2();
}
#endif
_____________________________________________



and compile with -D directive.

Say you want to use the file1 main for exe,
gcc -D_USE_FILE1_MAIN_ in your make file.
If you want to use the other one dont use
-D_USE_FILE1_MAIN_


Hope this helps

Many many thanks for your tip.

Yeah, you put f1() and f2() in funcs.c

Then it's simply

gcc -o prog1 file1.c funcs.c
gcc -o prog2 file2.c funcs.c
