Issue #12663 has been updated by Martin Dürst.

File mkmf.log added
File Makefile added
File extconf.h added
Status changed from Closed to Open

I'm sorry, but r55849 did not fix this at all. I still get exactly the same error messages. I'm attaching various files that have been created in ext/win32/resolv.

Bug #12663: Compilation error on cygwin
https://bugs.ruby-lang.org/issues/12663#change-60043

* Author: Martin Dürst
* Status: Open
* Priority: Normal
* Assignee: Nobuyoshi Nakada
* ruby -v: ruby 2.4.0dev (2016-07-30 trunk 55776) [x86_64-cygwin]
* Backport: 2.1: UNKNOWN, 2.2: UNKNOWN, 2.3: UNKNOWN
----------------------------------------
I get the errors below when compiling on cygwin. The problem may already be two or three days old; I'm sorry I overlooked it.
