Binary (pre-compiled) wallets are available on all platforms at https://ShieldCoin.github.io

Compiling Linux Wallet on Ubuntu/Debian (faster)

sudo rm -Rf ~/SHIELD #(if you already have it)

sudo apt-get -y install git && cd ~ && git clone https://github.com/ShieldCoin/SHIELD && cd SHIELD && sh go.sh

Compiling Linux Wallet on Ubuntu/Debian

Step 1. Install the dependencies.

sudo apt-get update

sudo apt-get install libdb-dev libdb++-dev build-essential libtool autotools-dev automake pkg-config libssl1.0-dev libevent-dev bsdmainutils git libboost-all-dev libminiupnpc-dev libqt5gui5 libqt5core5a libqt5webkit5-dev libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libqrencode-dev

Note: If you are on debian, you will also need to apt-get install libcanberra-gtk-module.

Step 2. Clone the git repository and compile the daemon and gui wallet:

git clone https://github.com/ShieldCoin/SHIELD && cd SHIELD && ./autogen.sh && ./configure --with-incompatible-bdb && make

if you are using source-build libdb4.8(++)-dev you may need to use

./configure CPPFLAGS="-I/usr/local/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/usr/local/BerkeleyDB.4.8/lib"

Note: If you get a "memory exhausted" error, make a swap file. (https://www.digitalocean.com/community/tutorials/how-to-add-swap-space-on-ubuntu-16-04)

Using the wallet:

The gui wallet is in ./SHIELD/src/qt and the daemon in ./SHIELD/src directories.

Note: If you see something like 'Killed (program cc1plus)' run dmesg to see the error(s)/problems(s). This is most likely caused by running out of resources. You may need to add some RAM or add some swap space.

Optional: If you want to copy the binaries for use by all users, run the following commands:

sudo cp src/SHIELDd /usr/bin/

sudo cp src/qt/SHIELD-qt /usr/bin/

Step 3. Creating a configuration file. Type cd ~ to get back to the home folder and type:

SHIELDd.exe (or ./SHIELDd if on mac or linux)

the output from this command will tell you that you need to make a Shield.conf and will suggest some good starting values.

For Linux users, type:

nano ~/.SHIELD/SHIELD.conf (For Windows users, see below. For mac users, the command is nano ~/Library/Application\ Support\SHIELD\SHIELD.conf)

Paste the output from the SHIELDd command into the Shield.conf like this: (It is recommended to change the password to something unique.)

rpcuser=Shieldrpcusername
rpcpassword=85CpSuCNvDcYsdQU8w621mkQqJAimSQwCSJL5dPT9wQX

Optional: Add rpcport=20103, port=21103, or algo=groestl to the configuration file.

Add daemon=1.

Your config may look something like this:

rpcuser=Shieldrpcusername
rpcpassword=85CpSuCNvDcYsdQU8w621mkQqJAimSQwCSJL5dPT9wQX
rpcport=20103
port=21103
daemon=1
algo=groestl

Exit the Shield.conf by pressing ctrl + x on your keyboard then pressing y and hitting enter. This should have created a Shield.conf file with what you just added.

Type SHIELDd.exe (or ./SHIELDd if on mac or linux) and your Shield daemon should start.

To check the status of how much of the blockchain has been downloaded (aka synced) type SHIELDd.exe getinfo (or ./SHIELDd getinfo if on mac or linux).

To compile on Mac (OSX El Capitan, but test compiled on Mountain Lion v10.8):

1. Ensure you do not have qt5 nor qt installed.

   brew install qt@5.5 boost@1.57 automake miniupnpc openssl protobuf protobuf berkeley-db@4
brew link boost@1.57 --force

2. Download the wallet source and build:

   git clone https://github.com/ShieldCoin/SHIELD

   cd SHIELD

   ./building/common.sh

   ./building/build.sh

   ./building/dist.sh

Building the Mac installer (.dmg) file

Run make deploy

If you are building the .dmg (by running 'mac deploy') you may need to run these commands if you get an error regarding mysql:

brew install mysql

cd /usr/local/qt5/5.4/clang_64/plugins/sqldrivers

otool -L libqsqlmysql.dylib

Note: This may be pointing to an version of mysql that you do not have installed (like mysql55) - Alternatively, you may be able to remove the library from the sqldrivers folder.

install_name_tool -change /opt/local/lib/mysql55/mysql/libmysqlclient.18.dylib /usr/local/Cellar/mysql/5.7.12/lib/libmysqlclient.20.dylib libqsqlmysql.dylib

Note: You may also run into issues when using macdeployqtplus to create the bundle, and the library will not bundle all of the boost dylibs. It's highly recommended to use the functions provided inside of dylib-fixes.sh

Trying to build .dmg on 10.8? You will need to run this:

export CFLAGS=-Qunused-arguments

export CPPFLAGS=-Qunused-arguments

sudo -E easy_install appscript

Want to use Docker?

Check out the readme for more information.

Want to 'solo-mine' from the wallet?

You can use the wallet to mine. You need to specify the algorithm (see below) and set the "gen" flag. For instance, in the configuration specify gen=1.

Using different algorithms (for mining)

To use a specific mining algorithm use the algo switch in your configuration file (.conf file) or from the command line (like this --algo=x17) Here are the possible values:

algo=x17
algo=scrypt
algo=groestl
algo=lyra
algo=blake

Using SHIELD on Windows

1. Download the pre-compiled software. (only from official SHIELD site) https://shieldcurrency.com/
2. Install
3. In windows file explorer, open c:\Users\XXX\AppData\Roaming\SHIELD (be sure to change XXX to your windows user)
4. Right click and create a new file SHIELD.txt
5. Edit the file to have contents above (see instructions above for options)
6. Save and close the file
7. Reame the file to SHIELD.conf
8. Start the SHIELD-qt program.
9. Open up SHIELD-qt console and run getinfo (or getmininginfo) to verify settings.

(Optional)
Add tor nodes using: https://github.com/ShieldCoin/SHIELD/wiki/Using-Tor-qt-nodes

Note: You must re-start the wallet after making changes to ShieldCoin.conf. How To build on Windows
