# BUILDING external libs (64-bit)
## Prepare Ubuntu environment
```
sudo apt-get install build-essential cmake tofrodos libtool-bin
sudo mkdir /opt/android
sudo chown $LOGNAME /opt/android
```
## Install Android NDK
```
cd /opt/android
wget https://dl.google.com/android/repository/android-ndk-r15c-linux-x86_64.zip
unzip android-ndk-r15c-linux-x86_64.zip
android-ndk-r15c/build/tools/make_standalone_toolchain.py --api 21 --stl=libc++ --arch aarch64 --install-dir /opt/android/tool64
```
## Build OpenSSL
Best is to compile openssl from sources. Copying from your phone or elsewhere (don't!) ends up in misery.
### Setup environment
```
cd /opt/android
wget https://wiki.openssl.org/images/7/70/Setenv-android.sh
fromdos Setenv-android.sh
```
Apply the following patch:
```

### Make symlinks
```

## Build Boost
```
cd /opt/android
wget https://sourceforge.net/projects/boost/files/boost/1.64.0/boost_1_64_0.tar.gz/download -O boost_1_64_0.tar.gz
tar xfz boost_1_64_0.tar.gz
(cd boost_1_64_0; ./bootstrap.sh)
```
The NDK r15c above gives errors about fsetpos and fgetpos not found(!?!), so we "just" comment them out in the include file:
`nano /opt/android/tool32/include/c++/4.9.x/cstdio` (`//using ::fgetpos`, `//using ::fsetpos`)
Then:
```
export PATH=/opt/android/tool64/aarch64-linux-android/bin:/opt/android/tool64/bin:$PATH
./b2 --build-type=minimal link=static runtime-link=static --with-chrono --with-date_time --with-filesystem --with-program_options --with-regex --with-serialization --with-system --with-thread --build-dir=android64 --stagedir=android64 toolset=clang threading=multi threadapi=pthread target-os=android stage
```
## Build & prepare zeromq
Only needed for zeromq versions (>v0.11.0.0).
```
cd /opt/android
git clone https://github.com/zeromq/zeromq3-x.git
export PATH=/opt/android/tool64/aarch64-linux-android/bin:/opt/android/tool64/bin:$PATH
export OUTPUT_DIR=/opt/android/zeromq
./configure --enable-static --disable-shared --host=aarch64-linux-android --prefix=$OUTPUT_DIR LDFLAGS="-L$OUTPUT_DIR/lib" CPPFLAGS="-isystem /opt/android/tool64/include/c++/4.9.x -fPIC -I$OUTPUT_DIR/include -Wno-error -D__ANDROID_API__=21" LIBS="-lgcc"
make
make install
git clone https://github.com/zeromq/cppzmq.git
cp cppzmq/*.hpp zeromq/include/
```
## And finally: Build Monero
```
cd /opt/android
git clone https://github.com/monero-project/monero
cd monero
```
```
# <patch monero code as needed>
# also, don't abort on warnings (this is only an issue >v0.11.0.0):

```
Ignore the warning from the last command - all static libraries are now in `lib`.
# Bringing it all together
- Copy all .a libraries into the appropriate `external-libs` folders.
- Copy `/opt/android/monero/src/wallet/wallet2_api.h` into `external-libs/monero/include`
