# BUILDING external libs
|
|
|
|
Based on https://forum.getmonero.org/5/support/87643/building-monero-v0-10-3-1-for-android and the internet.
|
|
|
|
Do not follow this blindly. These instructions are for 32-bit only. 64-bit building mostly involves
|
|
replacing "32" with "64".
|
|
|
|
## Prepare Ubuntu environment
|
|
|
|
```
|
|
sudo apt-install build-essential cmake tofrodos
|
|
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 arm --install-dir /opt/android/tool32
|
|
```
|
|
|
|
## 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
|
|
```
|
|
|
|
Edit Setenv-android.sh:
|
|
```
|
|
_ANDROID_EABI="arm-linux-androideabi-4.9"
|
|
_ANDROID_API="android-21"
|
|
```
|
|
Then:
|
|
```
|
|
export ANDROID_NDK_ROOT=/opt/android/android-ndk-r15c
|
|
. ./Setenv-android.sh
|
|
```
|
|
and ignore error about FIPS_SIG.
|
|
|
|
### Download and build OpenSSL
|
|
```
|
|
wget https://github.com/openssl/openssl/archive/OpenSSL_1_0_2l.tar.gz
|
|
tar xfz OpenSSL_1_0_2l.tar.gz
|
|
cd openssl-OpenSSL_1_0_2l/
|
|
perl -pi -e 's/install: all install_docs install_sw/install: install_docs install_sw/g' Makefile.org
|
|
./config shared no-ssl2 no-ssl3 no-comp no-hw no-engine --openssldir=/opt/android/openssl/android-21/
|
|
make depend
|
|
# Make sure we don't get versioned .so which Android can't deal with
|
|
make CALC_VERSIONS="SHLIB_COMPAT=; SHLIB_SOVER=" MAKE="make -e" all
|
|
mkdir -p /opt/android/openssl/android-21/lib
|
|
echo "place-holder make target for avoiding symlinks" >> /opt/android/openssl/android-21/lib/link-shared
|
|
make SHLIB_EXT=.so install_sw
|
|
```
|
|
|
|
### Make symlinks
|
|
```
|
|
cd /opt/android/tool32/sysroot/usr/include
|
|
ln -s ../../../../openssl/android-21/include/openssl
|
|
cd /opt/android/tool32/sysroot/usr/lib
|
|
ln -s ../../../../openssl/android-21/lib/libssl.so
|
|
ln -s ../../../../openssl/android-21/lib/libcrypto.so
|
|
```
|
|
|
|
## Build Boost
|
|
```
|
|
cd /opt/android
|
|
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/tool32/arm-linux-androideabi/bin:/opt/android/tool32/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=android32 --stagedir=android32 toolset=clang threading=multi threadapi=pthread target-os=android stage
|
|
```
|
|
|
|
## And finally: Build Monero
|
|
```
|
|
cd /opt/android
|
|
git clone https://github.com/monero-project/monero
|
|
cd monero
|
|
|
|
# <patch monero code as needed>
|
|
|
|
mkdir -p build/release.android32
|
|
cd build/release.android32
|
|
|
|
# only if not set already set
|
|
export PATH=/opt/android/tool32/arm-linux-androideabi/bin:/opt/android/tool32/bin:$PATH
|
|
|
|
CC=clang CXX=clang++ cmake -D BUILD_TESTS=OFF -D ARCH="armv7-a" -D STATIC=ON -D BUILD_64=OFF -D CMAKE_BUILD_TYPE=release -D ANDROID=true -D BUILD_TAG="android" -D BOOST_ROOT=/opt/android/boost_1_64_0 -D BOOST_LIBRARYDIR=/opt/android/boost_1_64_0/android32/lib -D OPENSSL_ROOT_DIR=/opt/android/openssl/android-21 -D CMAKE_POSITION_INDEPENDENT_CODE:BOOL=true ../..
|
|
make
|
|
|
|
find . -name '*.a' -exec cp '{}' lib \;
|
|
```
|
|
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`
