Hi Litecoin friends!
Im looking for a tut on how to cross compile the latest Litecoin on Ubuntu for windows. Most of the tut availible on the net are heavy out dated.

This is what i did so far without luck 
Just reinstalled my Ubuntu 20.4 server to try it again with a clean setup up
sudo apt-get update
apt-get upgrade -y
apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev -y
sudo apt-get install libdb4.8-dev libdb4.8++-dev libminiupnpc-dev libzmq3-dev libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libqrencode-dev g++-mingw-w64-i686 mingw-w64-i686-dev g++-mingw-w64-x86-64 mingw-w64-x86-64-dev curl -y
update-alternatives --config x86_64-w64-mingw32-g++
sudo apt-get install -y libxkbcommon-dev
sudo apt install xcb
sudo apt-get install libpcre3 libpcre3-dev
sudo apt-get install libpng-dev
sudo apt-get install -y libjpeg-dev
wget https://github.com/litecoin-project/litecoin/archive/refs/tags/v0.18.1.tar.gz
tar -xvzf v0.18.1.tar.gz
cd litecoin/depends
make download
make
cd ..
./autogen.sh
./configure --enable-glibc-back-compat --prefix=`pwd`/depends/x86_64-pc-linux-gnu LDFLAGS="-static-libstdc++"
make clean
make
make install
cd depends
make HOST=x86_64-w64-mingw32 -j4
cd ..
./configure --prefix=`pwd`/depends/x86_64-w64-mingw32

cd depends
make HOST=i686-w64-mingw32 -j4

Ill post the errors i get later…
ps this is still outdated
Change https://download.qt.io/official_releases/qt/5.9/$($(package)_version)/submodules to https://download.qt.io/archive/qt/5.9/$($(package)_version)/submodules
Simply use a desktop Linux and the qt installer from the official website?
meh i like pushing my self to do it the hard way 
so i can learn more
had this problem
util/time.cpp:85:5: error: ‘gmtime_r’ was not declared in this scope; did you mean ‘gmtime_s’?
fixed it with

Okay, install it on desktop and uninstall desktop after, nobody will find out 
I’ll tell it nobody
Also I don’t understands why u try to compile windows stuff on Linux 
By the way I don’t understand compiling windows stuff in anyway
already done that
Managed to build everything, even the latest release 
I am having an issue with this as well but it seems to be with the ./configure step. It compiles fine but even with the ./configure --prefix=pwd/depends/x86_64-w64-mingw32 and other steps, the configure output always comes out with target os: Linux. This of course causes it to only compile the linux binaries.
Sorry for late reply .Yes its building for linux and windows. Ill be updating my paste with some dependencies that i forgot to add like MiniUPnPc 
Everything some compile without any problems
Hello, thanks for sharing, it helps me a lot.
There is an error using Make install
