How To Compile Altcoin For Windows on Linux Using mxe and mingw

We are going to make altcoin qt for windows on ubuntu. We have clone peercoin and made a funcoin by replacing some parameter, I am assuming you have developed your coin.

First install required dependencies

sudo apt-get install autoconf automake autopoint bash bison bzip2 p7zip-full cmake flex gettext git g++ gperf intltool libffi-dev libtool libltdl-dev libssl-dev libxml-parser-perl make openssl patch perl pkg-config python ruby scons sed unzip wget xz-utils

sudo apt-get install g++-multilib libc6-dev-i386

move to any folder, here I am going in mnt folder and taking the fresh mxe clone.

cd /mnt
git clone https://github.com/mxe/mxe.git

Now compile boost

make MXE_TARGETS="i686-w64-mingw32.static" boost

Compile qt

make MXE_TARGETS="i686-w64-mingw32.static" qt

mxe does not support barkeley db and miniupnpc, so we have to compile these explicitly

compiling the barkeley db:

cd /mnt
wget http://download.oracle.com/berkeley-db/db-4.8.30.tar.gz
tar zxvf db-4.8.30.tar.gz
cd /mnt/db-4.8.30
touch compile-db.sh
chmod ugo+x compile-db.sh

now edit the compile-db.sh script file and put the below content and save

#!/bin/bash
MXE_PATH=/mnt/mxe
sed -i "s/WinIoCtl.h/winioctl.h/g" src/dbinc/win_db.h
mkdir build_mxe
cd build_mxe

CC=$MXE_PATH/usr/bin/i686-w64-mingw32.static-gcc \
CXX=$MXE_PATH/usr/bin/i686-w64-mingw32.static-g++ \
../dist/configure \
 --disable-replication \
 --enable-mingw \
 --enable-cxx \
 --host x86 \
 --prefix=$MXE_PATH/usr/i686-w64-mingw32.static

make

make install

for running the file command 

./compile-db.sh

 compiling miniupnpc

cd /mnt
wget http://miniupnp.free.fr/files/miniupnpc-1.6.20120509.tar.gz
tar zxvf miniupnpc-1.6.20120509.tar.gz
cd /mnt/miniupnpc-1.6.20120509
touch com-min.sh
chmod ugo+x com-min.sh

now edit the com-min.sh script file and put the below content and save

#!/bin/bash
MXE_PATH=/mnt/mxe

CC=$MXE_PATH/usr/bin/i686-w64-mingw32.static-gcc \
AR=$MXE_PATH/usr/bin/i686-w64-mingw32.static-ar \
CFLAGS="-DSTATICLIB -I$MXE_PATH/usr/i686-w64-mingw32.static/include" \
LDFLAGS="-L$MXE_PATH/usr/i686-w64-mingw32.static/lib" \
make libminiupnpc.a

mkdir $MXE_PATH/usr/i686-w64-mingw32.static/include/miniupnpc
cp *.h $MXE_PATH/usr/i686-w64-mingw32.static/include/miniupnpc
cp libminiupnpc.a $MXE_PATH/usr/i686-w64-mingw32.static/lib

for running the file command 

./com-min.sh

now add mxe bin to env PATH:

export PATH=/mnt/mxe/usr/bin:$PATH

now paste funcoin or take clone from github

cd /mnt
// paste your altcoin code
cd /mnt/funcoin
touch compile-coin.sh
chmod ugo+x compile-coin.sh

now edit compile-coin.sh file and paste the below content

#!/bin/bash
MXE_INCLUDE_PATH=/mnt/mxe/usr/i686-w64-mingw32.static/include
MXE_LIB_PATH=/mnt/mxe/usr/i686-w64-mingw32.static/lib

i686-w64-mingw32.static-qmake-qt4 \
 BOOST_LIB_SUFFIX=-mt \
 BOOST_THREAD_LIB_SUFFIX=_win32-mt \
 BOOST_INCLUDE_PATH=$MXE_INCLUDE_PATH/boost \
 BOOST_LIB_PATH=$MXE_LIB_PATH \
 OPENSSL_INCLUDE_PATH=$MXE_INCLUDE_PATH/openssl \
 OPENSSL_LIB_PATH=$MXE_LIB_PATH \
 BDB_INCLUDE_PATH=$MXE_INCLUDE_PATH \
 BDB_LIB_PATH=$MXE_LIB_PATH \
 MINIUPNPC_INCLUDE_PATH=$MXE_INCLUDE_PATH \
 MINIUPNPC_LIB_PATH=$MXE_LIB_PATH \
 QMAKE_LRELEASE=/mnt/mxe/usr/i686-w64-mingw32.static/qt/bin/lrelease funcoin-qt.pro

make -f Makefile.Release

now run the file by command ./compile-coin.sh

You will get the .exe file in release folder.

When error:

compilation terminated.
Makefile.Release:12634: recipe for target 'build/txdb-leveldb.o' failed
make: *** [build/txdb-leveldb.o] Error 1

Run this
