It works fine with runtime v9, and also with runtime v8 (and presumably earlier versions, too. However, I wouldn't be surprised if it's inferior to your approach. I'll do some checking and testing.

I don't know what the issue is. But to compile perl with mingw-w64 toolchain, I have to patch some files.

(Not that I doubted you ;-) Interestingly, perl builds fine for me straight out of the box with MSVC (Visual Studio-2019). This indicates that MSVC and MinGW-w64 (runtime-v9) must be taking different paths through this particular area of the perl source. I think my best chance is therefore to make the MinGW-w64 (runtime-v9) compilation follow the same path as the MSVC compilation - but, of course, that's OT for this list.

The output from v9 matches with the output of same code compiled with MSVC. To detect poll.h, curl does this https://github.com/curl/curl/blob/master/lib/select.h ___ Mingw-w64-public mailing list Mingw-w64-public@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mingw-w64-public
[Mingw-w64-public] WIN32_LEAN_AND_MEAN changes from runtime-8 to runtime-9
Hi,
The following script demonstrates a change between runtime version 8 and
runtime version 9.
/***/
#define WIN32_LEAN_AND_MEAN
#include
#ifndef _WINSOCKAPI_
#define NO__WINSOCKAPI_YET
# include
# include
#endif
#include
int main(void) {
#ifdef NO__WINSOCKAPI_YET
printf("_WINSOCKAPI_ not defined by windows.h\n");
#endif
#ifdef _WINSOCKAPI_
printf("_WINSOCKAPI_ now defined\n");
#endif
#ifdef POLLWRBAND
printf("POLLWRBAND defined\n");
#endif
return 0;
}
/***/
With 64-bit gcc-11.1.0, runtime version 8, it outputs:
_WINSOCKAPI_ not defined by windows.h
_WINSOCKAPI_ now defined
With 64-bit gcc-11.1.0, runtime version 9 (and 64-bit gcc-11.2.0, runtime
version 9) it outputs:
_WINSOCKAPI_ not defined by windows.h
_WINSOCKAPI_ now defined
POLLWRBAND defined
This seems odd to me.
Is that as expected and intended ?
I use the mingw-w64 ports provided by https://winlibs.com/
If I don't define WIN32_LEAN_AND_MEAN, then the outputs match - with
POLLWRBAND not being defined for both runtime versions.
This behaviour with v9 breaks builds of recent versions of perl, where we
hit source code like:
#if (defined(HAS_POLL) && defined(I_POLL)) || defined(POLLWRBAND)
# include
This breaks the perl build when POLLWRBAND is defined because there is no
file name poll.h to be found.
The obvious solution is to not define WIN32_LEAN_MEAN, and that's a
solution that works, but I just wanted to first check here that the failure
lies with the perl source and not with version 9.0.0 of the runtime.
There is also one other issue for perl being triggered by runtime-9 (and
for which I do already have a workaround), but I haven't yet worked out
exactly how it's triggered - so I won't ask about it until I have more
complete information.
Cheers,
Rob
