disclaimer

This program provides a Graphical User Interface (GUI) for the Komodo client tools that acts as a wrapper and presents the information in a user-friendly manner.

For security reasons it is recommended to always build the GUI wallet program from GitHub source. The details of how to build it are described below (easy to follow). Users who insist on downloading a binary release may instead use Komodo Desktop GUI Wallet - binary release v0.7.7-beta

1. Operating system and tools

   As of April 2017 the base software (Komodo v1.0.8) is mostly tested on Linux, Windows (experimental) and Mac OS X (experimental) (with same limitation as ZCash).
   The Linux tools you need to build and run the Wallet GUI are Git, Java (JDK7 or later) and Ant. If using Ubuntu Linux, they may be installed via command:

   user@ubuntu:~/build-dir$ sudo apt-get install git default-jdk ant
   

   For RedHat/CentOS/Fedora-type Linux systems the command is (like):

   user@centos:~/build-dir$ sudo yum install java-1.8.0-openjdk git ant
   

   The name of the JDK package (java-1.8.0-openjdk) may vary depending on the Linux system, so you need to check it, if name java-1.8.0-openjdk is not accepted. If you have some other Linux distribution, please check your relevant documentation on installing Git, JDK and Ant. The commands git, java, javac and ant need to be startable from command line before proceeding with build.

2. Building from source code

   As a start you need to clone the komodo-swing-wallet-ui Git repository:

   user@ubuntu:~/build-dir$ git clone https://github.com/ca333/komodo-swing-wallet-ui.git
   

   Change the current directory:

   user@ubuntu:~/build-dir$ cd komodo-swing-wallet-ui/
   

   Issue the build command:

   user@ubuntu:~/build-dir/komodo-swing-wallet-ui$ ant -buildfile ./src/build/build.xml
   

   This takes a few seconds and when it finishes, it builds a JAR file ./build/jars/KomodoSwingWalletUI.jar. You need to make this file executable:

   user@ubuntu:~/build-dir/komodo-swing-wallet-ui$ chmod u+x ./build/jars/KomodoSwingWalletUI.jar
   

   At this point the build process is finished the built GUI wallet program is the JAR file ./build/jars/KomodoSwingWalletUI.jar

3. Installing the built Komodo GUI wallet

3.1. If you have built Komodo from source code:

Assuming you have already built from source code Komodo in directory /home/user/komodo/src (for example - this is the typical build dir. for Komodo v1.0.5) which contains the command line tools komodo-cli and komodod you need to take the created file ./build/jars/KomodoSwingWalletUI.jar and copy it to diretcory /home/user/komodo/src (the same dir. that contains komodo-cli and komodod). Example copy command:

user@ubuntu:~/build-dir/komodo-swing-wallet-ui$ cp ./build/jars/KomodoSwingWalletUI.jar /home/user/komodo/src    

3.2. If you have installed the Komodo binary packages

The command line tools komodo-cli and komodod are placed by the package installer in:

/usr/bin/komodo-cli
/usr/bin/komodod

The Komodo GUI wallet knows how to find them there. You may place the file ./build/jars/KomodoSwingWalletUI.jar anywhere in your /home directory that you find convenient and start it from there.

4. Running the installed Komodo GUI wallet

   Before running the GUI you need to start komodod (e.g. komodod --daemon). The wallet GUI is a Java program packaged as an executable JAR file. It may be run from command line or started from another GUI tool (e.g. file manager). Assuming you have already installed Komodo and the GUI Wallet KomodoSwingWalletUI.jar in directory /home/user/komodo/src one way to run it from command line is:

   user@ubuntu:~/build-dir/komodo-swing-wallet-ui$ java -jar /home/user/komodo/src/KomodoSwingWalletUI.jar
   

   If you are using Ubuntu (or similar ;) Linux you may instead just use the file manager and right-click on the KomodoSwingWalletUI.jar file and choose the option "Open with OpenJDK 8 Runtime". This will start the Komodo GUI wallet.

1. Limitation: Wallet encryption has been temporarily disabled in ZCash due to stability problems. A corresponding issue #1552 has been opened by the ZCash developers. Correspondingly wallet encryption has been temporarily disabled in the ZCash Desktop GUI Wallet.
2. Issue: the GUI wallet does not work correctly if zcashd is started with a custom data directory, like: zcashd -datadir=/home/data/whatever This will be fixed in later versions.
3. Issue: GUI data tables (transactions/addresses etc.) allow copying of data via double click but also allow editing. The latter needs to be disabled.
4. Limitation: The list of transactions does not show all outgoing ones (specifically outgoing Z address transactions). A corresponding issue #1438 has been opened for the ZCash developers.
5. Limitation: The CPU percentage shown to be taken by zcashd on Linux is the average for the entire lifetime of the process. This is not very useful. This will be improved in future versions.
