MinGW build target

MinGW build target

[Glenn Burkhardt]

What's the correct build target for MinGW-w64?  I tried using

      --build=x86_64-w64-mingw64

with gdb-7.11.1 and x86_64-6.1.0-release-posix-seh-rt_v5-rev0, and it's 
trying to compile ser-unix.c.  That doesn't seem right, and, of course, 
MinGW doesn't include <sys/socket.h>.

Why do you need an explicit argument?  Doesn't config.guess guess
correctly?  If not, maybe your uname needs and update/upgrade?

In any case, it sounds like x86_64-w64-mingw32 is what you want.

To answer the question of "why" - on Windows, the config.guess output is
not always what you want, as it depends on how you execute that script.
In our case, we build using a cygwin environment, so config.guess
returns a cygwin triplet. So, when you actually want to build a MinGW
debugger, you have to pass the MinGW triplet explicitly.

Thanks - that works better.  I suppose that the '32' on 'mingw32' is an 
artifact that predates the MinGW-w64 fork of the MinGW code base.

Correct.  The MinGW-w64 code doesn't include 'uname'.  I'm using Msys2 
as a shell, along with its support programs, which include 'uname'.  On 
Msys2,
