[HOWTO] compile altcoin for windows on linux using mxe and mingw

[qjusam]

All went ok with some trial and errors but i am stuck on last step with following error

/src/leveldb/libmemenv.a: error adding symbols: Archive has no index; run ranlib to add one
collect2: error: ld returned 1 exit status
Makefile.Release:453: recipe for target 'release/coin-qt.exe' failed

I have already made db by using following command

Code:

#!/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

RANLIB=$MXE_PATH/usr/bin/i686-w64-mingw32.static-ranlib \
CC=$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

Still awaiting a solution. if anyone know??

Hello everyone,

I decided to revisit this and ended up discovering the build script for BerkeleyDB initially posted in this thread by the OP is quite incorrect.

Here is the correct syntax!

Code:

#!/bin/bash

## Path to MXE source
 MXE_PATH=/home/demon/dev/mxe
## Path for mingw headers
 MXE_INCLUDE=$MXE_PATH/usr/i686-w64-mingw32.static/include

## Path to db source
 db=db-6.1.26


## Make a clean working tree / Create working DIR
## You can also use `make distclean` within build_mxe to start fresh
 rm -rf ./$db/build_mxe
 mkdir -p ./$db/build_mxe

 cd ./$db/build_mxe

## Correct naming of header file
 sed -i "s/WinIoCtl.h/winioctl.h/g" ../src/dbinc/win_db.h


## Define CC and C++ compiler & user level commands
export CC=$MXE_PATH/usr/bin/i686-w64-mingw32.static-gcc
export CXX=$MXE_PATH/usr/bin/i686-w64-mingw32.static-g++
export AR=$MXE_PATH/usr/bin/i686-w64-mingw32.static-ar
export STRIP=$MXE_PATH/usr/bin/i686-w64-mingw32.static-strip
export RANLIB=$MXE_PATH/usr/bin/i686-w64-mingw32.static-ranlib

### Find mingw headers in non-standard directory
export CPPFLAGS=-I$MXE_INCLUDE


## Configure the build
 ../dist/configure \
     --build=x86_64-pc-linux-gnu \
     --host=x86 \
     --disable-replication \
     --enable-cxx \
     --enable-mingw \
     --program-transform-name='s,.exe,,;s,\(.*\),\1.exe,' \
     --prefix=/home/demon/dev/mxe_db \
     --exec-prefix=/home/demon/dev/mxe_db

## Build DB and install it
 make -j(nproc); make -j(nproc) install

Being it's not clear exactly what you are trying to do. But compiling with MXE on linux will produce the platform versions you need. Also ofc secp has had recent updates on their repo, and you should work with whatever code may already exist with the project you're working on.

If you have levelDB issue (libleveldb.a / libmemenv.a), plz follow below instruction.

Code:

cd %coin_folder%/src/leveldb
TARGET_OS=NATIVE_WINDOWS make libleveldb.a libmemenv.a CC=/mnt/mxe/usr/bin/i686-w64-mingw32.static-gcc CXX=/mnt/mxe/usr/bin/i686-w64-mingw32.static-g++

It's really works, thanks a lot.
