Question

I’m trying to configure Mingw64(mingw-w64-v3.1.0.tar.bz2).

I ran ./configure and got following messages.

configure: Configuration Options Summary:
configure:
configure:   WinCE runtime........: no
configure:   Win32 runtime........: yes
configure:   Win64 runtime........: no

The configuration itself was fine. I was able to install it.

But directory name which mingw was installed is lib32

I think I haven’t installed Mingw64 for 64bit as configuration message said.

How can I configure it for 64bit?

I’ve tried –build option like ./configure –build=x86_64-w64-mingw32.

Was it helpful?

Solution

First, you need to make sure you have a cross-compiler GCC and binutils (i.e. x86_64-w64-mingw32-[gcc,ld,dlltool,...]) in PATH. Then, you can configure the mingw-w64-crt (do not use the toplevel configure itself) with:

/path/to/mingw-w64-crt/configure --host=x86_64-w64-mingw32 --enable-lib64 --disable-lib32

But the question is, why do you want to do this? There is a lot that can go wrong when building a toolchain, and there is a multitude of binaries available for virtually any platform.
