inline void foo(){}

int main(){foo();}

That seemingly innocent code gives the following linker error:

$gcc -std=c99 -Wall -Wextra -pedantic inlinetest.c

/tmp/cc4A48Yu.o: In function `main':

inlinetest.c:(.text+0x12): undefined reference to `foo'

collect2: ld returned 1 exit status

Edit:
I didn't check that you were coding in C. I never tried to inline a function in C, so i don't know why that happens.

Dunno.

Clean out the project directory, etc.?

I don't think inline functions are part of C. As far as I remember were supposed to replace (at least partially) macro's and were something new of C++ that did not appear in C.
Plus , you don't return an integer in main.

So, after all it was like i was saying at my first post? it acts like C++. Inline functions are like macros, they expand then called, so you can't produce object code from them.

No, inline functions are part of C99, and some compilers supported it as an extension before C99.
