different method signatures for mingw and visual c

I am writing code to be compiled with both MinGW and Visual C compiler. I am using define like this:

I have defined VISUAL_STUDIO In my project file as follows:

Code:

---

QMAKE_CFLAGS_DEBUG += -O2 VISUAL_STUDIO
                    QMAKE_CFLAGS += -O2 -DVISUAL_STUDIO

---

I get multiple definition error for the following code

Code:

---

#ifdef VISUAL_STUDIO
int FUNCA(
#else
static inline int FUNCA(
#endif
    Pkt_t *pkt
    )

---

Can anybody help me with this or any idea to do it in different was will be appreciated?

why do you have -D in one, but not the other?

also, maybe you're just including the file too many times... It's hard to tell without a complete compilable example - see my sig.

You get a multiple definition of which symbol exactly? Are you sure this is caused by your defines and not a non-inlined function declaration in line #2?
