Hi,
I'm trying to dllexport/dllimport an inline function, but I get this
warning:
```
inline function ‘g_strcmp0’ declared as dllimport: attribute ignored [-
Wattributes]
```
This is when cross compiling my code on Linux for Windows using mingw.
The relevant code is
```
GLIB_API inline
int g_strcmp0 (const char *str1,
const char *str2)
{
if (!str1)
return -(str1 != str2);
if (!str2)
return str1 != str2;
return strcmp (str1, str2);
}
```
Where GLIB_API is defined to `__declspec(dllexport)` when compiling the
DLL and `__declspec(dllimport)` when including the header from
application.
The goal is to get that function inlined when doing `if (g_strcmp0(a,
b))`, but get address from instance in the DLL when doing
`do_sort(array, g_strcmp0)`.
I believe dllimport of inline function should be supported, it compiles
fine with MSVC. It is even documented there:
https://learn.microsoft.com/en-us/cpp/cpp/defining-inline-cpp-functions-with-dllexport-and-dllimport?view=msvc-170
I believe (but not tested myself) that clang had the same issue but got
fixed years ago: https://reviews.llvm.org/D3772
For context, I'm hitting this issue when working on that GLib patch:
https://gitlab.gnome.org/GNOME/glib/-/merge_requests/2926
Is there a trick to get that working with GCC? Or should that issue be
reported somewhere?
Regards,
