Issues cross-compiling bet for windows with mingw-w64

[satindergrewal]

Tried cross-compiling bet for windows on Ubuntu 18.04 with mingw-w64 and got same issues as #261

sudo apt-get install -y \
  autoconf automake build-essential git libtool libgmp-dev \
  libsqlite3-dev python3 net-tools zlib1g-dev libsodium-dev \
  gettext wget libcurl3-gnutls ninja-build libssl-dev \
  libcurl4-gnutls-dev libevent-dev

sudo apt-get install -y \
  autoconf automake build-essential git libtool libgmp-dev \
  libsqlite3-dev python3 python3-mako net-tools zlib1g-dev libsodium-dev \
  gettext

sudo apt install mingw-w64

export target_host=x86_64-w64-mingw32

export AR=$target_host-ar
export AS=$target_host-as
export CC=$target_host-gcc
export CXX=$target_host-g++
export LD=$target_host-ld
export STRIP=$target_host-strip

git clone https://github.com/chips-blockchain/bet
cd bet
./configure

# Same configurator error as ARM compilation

Please hold on any efforts to make it cross-compile for now. I need to test something and push update for that in build system.

[satindergrewal]

I just noticed that the build system which is derived from c-lightning project doesn't has Windows installation support in it. So, that probably means this build system wasn't meant to compile for Windows and most probably will have issues.

Still exploring it further.

Another relevant comment from the dependency repository ccan, which indicates this code might be hard to compile for windows as is in current state: rustyrussell/ccan#28 (comment)

I tried again in Ubuntu 16.04 Docker container and got little different error this time:

apt-get update && \
	DEBIAN_FRONTEND=noninteractive apt-get install -y \
	autoconf automake build-essential sudo git libtool libgmp-dev \
	libsqlite3-dev python3 python3-mako net-tools zlib1g-dev libsodium-dev \
	gettext wget libcurl3-gnutls ninja-build libssl-dev \
	libcurl4-gnutls-dev libevent-dev
sudo apt install build-essential libtool autotools-dev automake pkg-config bsdmainutils curl git
sudo apt install g++-mingw-w64-x86-64

Closing this issue, since it seems it'll not be feasible to achieve it with current dependency setup.
Unless specific dependencies in ccan are identified and are setup to compile/use individually, this issue might not resolve.
