Compile Monero 0.9 on Arch Linux

The example shows how to compile the current github version of Monero, as of 8 Sep 2016, on Arch Linux.

Dependencies

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

#install git to download latest Monero source code from github
sudo pacman -Su --needed git

# install dependencies to be able to compile Monero
sudo pacman -Su --needed base-devel cmake boost miniupnpc unbound graphviz doxygen libunwind pkg-config openssl curl gtest

Compilation

# download the latest monero source code from github
git clone https://github.com/monero-project/bitmonero.git

# go into monero 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 -
#

# apply a patch for gcc 6.1
wget -q -O - https://raw.githubusercontent.com/moneroexamples/compile-monero-09-on-arch-linux/master/fix_value_initialization.patch | git apply  -v -

# compile
make release

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/monero/ folder. This can be done in the following way:

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

This should result in:

/opt/monero/
├── monero-blockchain-export
├── monero-blockchain-import
├── monerod
└── monero-wallet-cli

Now we can start the Monero daemon, i.e., monerod, and let it download the blockchain and synchronize itself with the Monero network. After that, you can run your the monero-wallet-cli.

# launch the Monero daemon and let it synchronize with the Monero network
/opt/monero/monerod

# launch the Monero wallet
/opt/monero/monero-wallet-cli

Useful aliases (with rlwrap)

monerod and monero-wallet-cli do not have tab-compliton nor history. This problem can be overcome using rlwrap.

# install rlwrap
sudo pacman -Su rlwrap wget

# download monerod and monero-wallet-cli 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 ~/.monero/monerocommands_simplewallet.txt /opt/monero/monerod'" >> ~/.bashrc
echo "alias monerowallet='rlwrap -f ~/.bitmonero/monerocommands_bitmonerod.txt /opt/monero/monero-wallet-cli'" >> ~/.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/monero-dev/libs is the folder where they are going to be copied to.

# create the folder
sudo mkdir -p /opt/monero-dev/libs

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

This should results in the following file structure:

/opt/monero-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
├── libringct.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/monero-dev/headers is assumed to hold the headers.

# create the folder
sudo mkdir -p /opt/monero-dev/headers

# find the header files (i.e., those with extension of *.h)
# and copy them to /opt/monero-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/monero-dev/headers

This should results in the following file structure:

# ... only part shown to save some space
├── src
│   ├── blockchain_db
│   │   ├── berkeleydb
│   │   ├── blockchain_db.h
│   │   ├── db_types.h
│   │   └── lmdb
│   ├── blockchain_utilities
│   │   ├── blockchain_utilities.h
│   │   ├── blocksdat_file.h
│   │   ├── bootstrap_file.h
│   │   ├── bootstrap_serialization.h
│   │   └── fake_core.h
│   ├── blocks
│   │   └── blocks.h

How can you help?

Constructive criticism, code and website edits are always good. They can be made through github.
