That's because you compiled it as C. I used g++ to compile these, and there was no such error.


For C, this inline issue is going to be much more messy due to lack of COMDAT support about 
`inline`. Your will need a dedicated macro for each translation unit. A dirty solution looks like this:

    ```
    #ifndef INSIDE_FOO_C
    __attribute__((__dllexport__)) inline
    #endif
    extern
    int
    g_strcmp0(const char*str1, const char*str2)
      ...
    ```

and in 'foo.c':

    ```
    #define INSIDE_FOO_C  1
    #include "foo.h"

    extern int g_strcmp0 (const char *str1, const char *str2);
    ```
