multiple definition of `main'

multiple definition of `main'

[Devrim Erdem]

Hello,

I am having a problem of multiple definitions which I couldn't figure out.

The full linker is here :

Obj_Linux_IA32/Graphics.a(DynModel.o): In function `Gfx::TestModel 
type_info function':
/vires/devrim/Projects/Fstd/Src/Modules/Graphics/DynModel.hh(.text+0x0): 
multiple definition of `main'
.Obj_Linux_IA32/Graphics.a(Graphics.o)(.text+0x0):/vires/devrim/Projects/Fstd/Src/Modules/Graphics/Graphics.cc: 
first defined here
collect2: ld returned 1 exit status

This happens when I use the class TestModel ( which is in DynModel.hh ). It is true that Graphics.cc has a main but it is definetely not multiply defined.

I had experienced similar problems when I implement a class method in header file out of the class scope without using the "inline" word. Adding inline would fix those. This one makes me clueless. 

Any ideas...?

gcc-2.95.3-124 on SuSE 7.3

Regards.

RE: multiple definition of `main'

[???]

Including of header file equal to insert the the whole of the header file
into the line where '#include' appeared.
if you have header file myheader.h, mycfile1.c,mycfile2.c:

/*************************myheader.h***********************************/
void myfunction(){printf("a function in a header file without inline");}
/*************************end of
myheader.h***********************************/


/*************************mycfile1.c***********************************/
#include "myhdaer.h"
void main(){}
/*************************end of
mycfile1.c***********************************/

/*************************mycfile1.c***********************************/
#include "myhdaer.h"
void something(){}
/*************************end of
mycfile1.c***********************************/

then mycfile1.c equal to :

void myfunction(){printf("a function in a header file without inline");}
void main(){}

and mycfile2.c equal to:

void myfunction(){printf("a function in a header file without inline");}
void something(){}

when you link the two file together, you will get a multiple definitions
error,
but if myfunction is inlined ,it's ok.
