# Compile Monero 0.9 on Ubuntu 16.04 x64

The example shows how to compile the current github version of Monero, as of 10 Jul 2016, on Ubuntu 16.04 x64.

Dependencies

Before proceeding with the compilation, the following packages are required:

# update Ubuntu's repository sudo apt update #install git to download latest Monero source code from github sudo apt install git # install dependencies to be able to compile Monero sudo apt install build-essential cmake libboost-all-dev miniupnpc libunbound-dev graphviz doxygen libunwind8-dev pkg-config # or git and all dependencies in one command # sudo apt install git build-essential cmake libboost-all-dev miniupnpc libunbound-dev graphviz doxygen libunwind8-dev pkg-config

Compilation

# download the latest bitmonero source code from github git clone https://github.com/monero-project/bitmonero.git # go into bitmonero folder cd bitmonero/ # apply patch for using Onion Blockchain Explorer (optional) # https://github.com/moneroexamples/onion-monero-blockchain-explorer # curl https://raw.githubusercontent.com/moneroexamples/compile-monero-09-on-ubuntu-16-04/master/res/tx_blob_to_tx_info.patch | git apply -v - # # compile the release version. make # or make -j number_of_threads, e.g., make -j 2 # alternatively `make release` can be used instead of `make`. This compiles # the source code without compiling unique tests which is faster, and can # avid problems if there are compilation errors with compiling the tests

Installation

After successful compilation, the Monero binaries should be located in ./build/release/bin as shown below:

./build/release/bin/ ├── bitmonerod ├── blockchain_converter ├── blockchain_dump ├── blockchain_export ├── blockchain_import ├── cn_deserialize ├── connectivity_tool ├── simpleminer └── simplewallet

I usually move the binaries into /opt/bitmonero/ folder. This can be done as follows:

# optional sudo mkdir -p /opt/bitmonero sudo mv -v ./build/release/bin/ * /opt/bitmonero/

This should result in: bash /opt/bitmonero ├── bitmonerod ├── blockchain_converter ├── blockchain_dump ├── blockchain_export ├── blockchain_import ├── cn_deserialize ├── connectivity_tool ├── simpleminer └── simplewallet

Now we can start the Monero daemon, i.e., bitmonerod , and let it download the blockchain and synchronize itself with the Monero network. After that, you can run your the simplewallet .

# launch the Monero daemon and let it synchronize with the Monero network /opt/bitmonero/bitmonerod # launch the Monero wallet /opt/bitmonero/simplewallet

Useful aliases (with rlwrap)

bitmonerod and simplewallet do not have tab-compliton nor history. This problem can be overcome using rlwrap.

# install rlwrap sudo apt install rlwrap # download bitmonerod and simplewallet commands files wget -O ~/.bitmonero/monerocommands_bitmonerod.txt https://raw.githubusercontent.com/moneroexamples/compile-monero-09-on-xubuntu-16-04-beta-1/master/monerocommands_bitmonerod.txt wget -O ~/.bitmonero/monerocommands_simplewallet.txt https://raw.githubusercontent.com/moneroexamples/compile-monero-09-on-xubuntu-16-04-beta-1/master/monerocommands_simplewallet.txt # add aliases to .bashrc echo "alias moneronode='rlwrap -f ~/.bitmonero/monerocommands_bitmonerod.txt /opt/bitmonero/bitmonerod'" >> ~/.bashrc echo "alias monerowallet='rlwrap -f ~/.bitmonero/monerocommands_simplewallet.txt /opt/bitmonero/simplewallet'" >> ~/.bashrc # reload .bashrc source ~/.bashrc

With this, we can just start the daemon and wallet simply using moneronode and monerowallet commands. rlwrap will provide tab-complition and history for the monero programs.

Monero C++11 development (optional)

If you want to develop your own C++11 programs on top of Monero 0.9, Monero’s static libraries and headers will be needed. Below is shown how they can be setup for use to write your own C++11 programs based on Monero. An example of such a program is access-blockchain-in-cpp.

Monero static libraries

When the compilation finishes, a number of static Monero libraries should be generated. We will need them to link against in our C++11 programs.

Since they are spread out over different subfolders of the ./build/ folder, it is easier to just copy them into one folder. I assume that /opt/bitmonero-dev/libs is the folder where they are going to be copied to.

# create the folder sudo mkdir -p /opt/bitmonero-dev/libs # find the static libraries files (i.e., those with extension of *.a) # and copy them to /opt/bitmonero-dev/libs # assuming you are still in bitmonero/ folder which you downloaded from # github sudo find ./build/ -name '*.a' -exec cp -v {} /opt/bitmonero-dev/libs \;

This should results in the following file structure:

bash /opt/bitmonero-dev/ └── libs ├── libblockchain_db.a ├── libblocks.a ├── libcommon.a ├── libcrypto.a ├── libcryptonote_core.a ├── libcryptonote_protocol.a ├── libdaemonizer.a ├── libgtest.a ├── libgtest_main.a ├── liblmdb.a ├── libminiupnpc.a ├── libmnemonics.a ├── libotshell_utils.a ├── libp2p.a ├── librpc.a └── libwallet.a

Monero headers

Now we need to get Monero headers, as this is our interface to the Monero libraries. Folder /opt/bitmonero-dev/headers is assumed to hold the headers.

# create the folder sudo mkdir -p /opt/bitmonero-dev/headers # find the header files (i.e., those with extension of *.h) # and copy them to /opt/bitmonero-dev/headers. # but this time the structure of directories is important # so rsync is used to find and copy the headers files sudo rsync -zarv --include = "*/" --include = "*.h" --exclude = "*" --prune-empty-dirs ./ /opt/bitmonero-dev/headers

This should results in the following file structure:

# only src/ folder with up to 3 level nesting is shown /opt/bitmonero-dev/headers/src/ ├── blockchain_db │ ├── berkeleydb │ │ └── db_bdb.h │ ├── blockchain_db.h │ ├── db_types.h │ └── lmdb │ └── db_lmdb.h ├── blockchain_utilities │ ├── blockchain_utilities.h │ ├── blocksdat_file.h │ ├── bootstrap_file.h │ ├── bootstrap_serialization.h │ └── fake_core.h ├── blocks │ └── blocks.h ├── common │ ├── base58.h │ ├── boost_serialization_helper.h │ ├── command_line.h │ ├── dns_utils.h │ ├── http_connection.h │ ├── i18n.h │ ├── int-util.h │ ├── pod-class.h │ ├── rpc_client.h │ ├── scoped_message_writer.h │ ├── unordered_containers_boost_serialization.h │ ├── util.h │ └── varint.h # ... the rest not shown to save some space
