Install Money Manager EX in Ubuntu 16 - MMEX

Money Manager EX is a nice tool to keep track of personal finances and expenses. And while installers exist for windows, in Linux one has to compile the software alone. This has proven to be somewhat more difficult than expected, but with the right dependencies and following the guide it is possible.

Compile from git repository and install

Following the Ubuntu guide from Github one needs to do,
  1. Install dependencies
    sudo apt-get update && sudo apt-get upgrade
    sudo apt-get install git build-essential automake libwxbase3.0-dev libwxgtk3.0-dev libwxgtk-webview3.0-dev python-dev build-essential cmake git libgtk-3-dev libwebkitgtk-dev libwxgtk3.0-dev libwxgtk-webview3.0-dev libwxsqlite3-3.0-dev
    (In the github documentation the latter libwsqlite3-3.0-dev is not mentioned, however it is necessary for compiling. Without this I was getting errors while compiling)
  2. Clone the git repository
    git clone --recursive
    (I found that the --recursive parameter is important, otherwise I got some files missing in the end)
  3. For the release (no debugging build) configure and compile as
    cd moneymanagerex/build
    mkdir release
    cd release
    cmake -DCMAKE_BUILD_TYPE=Release ../../
    make package
  4. After this you can install it with
    sudo make install
  5. and finally run from the terminal window with
MMEX running under Ubuntu 16

Note: For make you can pass the argument "-j x" where x is the number of threads to use.

Creating a desktop launcher

Create a file called Mmex.desktop (yes, .desktop) on your desktop.
nano ~/Desktop/Mmex.desktop
Paste the following into the file
#!/usr/bin/env xdg-open
[Desktop Entry]
Comment=Money Manager
Make the file executable with
chmod +x ~/Desktop/Mmex.desktop
You should be left with the following, a nice desktop launcher.
Mmex desktop launcher and the location of the Icon
What is what?
Exec - command that gets executed
Name - The visible name of the file (hence you don't see the .desktop extension)
Comment - Additional comment if you like
Icon - path to the icon to display, otherwise blank launcher image

A job is running for dev-mapper-cryptswap1.device

If you notice that booting Ubuntu takes a long time and you see the following error message on the booting screen after pressing 'ESC',
A job is running for dev-mapper-cryptswap1.device (50s / 1m30s)

This is caused by the system looking for an encrypted swap partition, however most likely you have not created one. Which is normal, now when a lot of RAM is available, and a swap partition is not necessary. This is all due to a misconfiguration entry in the fstab, which tells the system to try and mount the said (non existing) partition.


The solution is to remove or comment out the "cryptswap" entries from /etc/fstab and /etc/crypttab.

This can be done easily by editing the above mentioned files as commenting out the lines that say cryptswap by placing a "#" in front of the matching lines.
sudo nano /etc/fstab
sudo nano /etc/crypttab
The result is shown below in the image, where the lines referring to the cryptswap partition are already commented out.

Reminder: 'CTRL + O' saves the file, 'CTRL + X' exits the nano text editor.

Both fstab and crypttab have an entry for cryptswap1, shown as already commented out
