I have never tried to manually cross compile. I usually setup gitian builder virtual machine and simply run gitian scripts: ./bin/gbuild -m 8000 -j 12 --commit emercoin=v0.7.2emc /home/evgenij/programming/c++/emercoin/contrib/gitian-descriptors/gitian-linux.yml

And it will produce aarch64 files without any problems. You can study gitian-linux.yml to find out how it compiles aarch version, but I would personally recommended to just install gitian builder - it's much simpler.

Or I can compile aarch64 binaries with gitian builder for you and upload them to source forge. And please note: we have not tested those versions yet, so I'm not sure if they can run without any issues.

please provide an ARM linux version wallet. it is too hard to build one

Ok, I will add arm version in next release on github.

That'll be Fantastic! can you make 0.8 now that it's released?

Sorry, I do not build ARM versions, since 0.7.12. I do not have native MAC, and cross-compiler does not work correctly. If you will able to build yourself, you're welcome, I will assist you with examples, how to build for Linux/Windows.

That'd be very nice to have example, Thank you. it's for Raspberry Pi 3/4 and regular cross-compilations returns data format error

OK. How to build portable compilation for Linux:

yum install bzip2
 yum install aclocal
 yum install automake
 yum install autotools-dev
 yum install libtool
 yum install patch
 yum install xkb
 yum install libxkbcommon
 yum install autotools-dev
 yum install git
 yum install x11-xkb-utils # need for QT keyboard
 
Далее, если собирать с bip70, вручную ставить protobuf, нужный для BIP70:
https://stackoverflow.com/questions/31955260/no-package-protobuf-devel-available-error-on-centos-7
Но если с ним собирать, он цепляется как шареная библиотека, и прога не запускается. Так что собираю без него.


git clone https://github.com/emercoin/emercoin.git
cd emercoin/
git checkout 0.8.0-dev
cd depends
make HOST=x86_64-pc-linux-gnu -j 5
cd ..
./autogen.sh

./configure --prefix=$PWD/depends/x86_64-pc-linux-gnu --disable-tests --disable-util-tx --disable-gui-tests --disable-hardening --disable-debug --with-gui=qt5

How to build cross-compilation for Windows with MinGW:

1. Install MinGW
2. Into the file /usr/x86_64-w64-mingw32/include/sdkddkver.h add line:

#define _WIN32_WINNT 0x0600

Start build depends:

cd depends
make HOST=x86_64-w64-mingw32 -j 4

Build failed on Qt. Edit file depends/work/build/x86_64-w64-mingw32/qt/5.9.8-4b53a20f283/qtbase/src/corelib/tools/qbytearraymatcher.h. Add here
#include <limits>

4. Continue with same command:

make HOST=x86_64-w64-mingw32 -j 4

5. Continue cross-build

cd ..
./autogen.sh
./configure --disable-dependency-tracking --prefix=$PWD/depends/x86_64-w64-mingw32 --disable-tests --disable-util-tx --disable-gui-tests  --disable-hardening --disable-debug --disabel-asm
