Issue #10632 has been updated by Luis Lavena.


Can you provide specifics about the version of mingw-w64 you used?

You say "4.9.2", but there are many builds of it. Care to provide the link to the compiler you downloaded?

Thank you.

Bug #10632: 2.2rc1 Fails to Compile with Mingw64 NET_LUID
https://bugs.ruby-lang.org/issues/10632#change-50563

* Author: Charlie Savage
* Status: Open
* Priority: High
* Assignee: 
* Category: platform/mingw
* Target version: current: 2.2.0
* ruby -v: ruby 2.1.5p273 (2014-11-13 revision 48405) [x64-mingw32]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
Ruby 2.1.* compile correctly with mingw64.  Ruby 2.2rc1 does not.  The error is:

<pre>
gcc version 4.9.2 (x86_64-posix-seh-rev0, Built by MinGW-W64 project)

 } NET_LUID, *PNET_LUID;
</pre>

My config line (same I use for ruby 2.1.x):

<pre>
$ ./configure --prefix=/ --enable-shared=yes CPPFLAGS=-Ic:/mingw64/mingw64/local/include LDFLAGS=-Lc:/mingw64/mingw64/local/lib --build=x86_64-w64-mingw32 --host=x86_64-w64-mingw32
</pre>

Let me know if you need additional info.
