3. System Administrator Notes

3.1 Dependencies

In order to compile and run mtCellEdit you must have several packages already present on your system:

These must also include library headers, which some operating systems provide in separate packages.

mtCellEdit then requires various libraries that I have created:

Package Dependencies Description
libmtKit zlib Low level C routines, including strings, UTF-8, ZIP file handling, preferences, trees.
libmtcelledit libmtKit The spreadsheet engine, including all file handling and general operations.
libmtPixy libmtKit, zlib, libpng, libjpeg, giflib, FreeType, Pango, Cairo The core pixel engine, including all file handling and general operations.
libmtCedUI libmtKit, libmtPixy, libmtcelledit, FreeType, Pango, Cairo Toolkit agnostic UI code, e.g. graph and sheet rendering.
libmtQEX libmtKit, libmtPixy, Qt5 Various Qt function utilities including preferences editor.

The other optional parts of the suite have these dependencies:

Package Dependencies Description
libmtPixyUI libmtKit, libmtPixy Toolkit agnostic UI code, e.g. undo stack
mtCedCLI libmtKit, libmtcelledit, libmtCedUI, readline Command line spreadsheet
mtCedUtils libmtKit, libmtcelledit Command line text tools
mtEleana libmtKit, libmtcelledit, libmtPixy, libmtQEX, Cairo, Qt5 General election analysis
mtNetlog libmtKit, libmtcelledit Network logging
mtPixy libmtKit, libmtPixy, libmtPixyUI, libmtQEX, Qt5 Pixel image editor
mtPixyCLI libmtKit, libmtPixy, libmtPixyUI, readline Command line pixel image editor
mtPixyUtils libmtKit, libmtPixy Command line pixel image tools
mtRaft libmtKit, libmtcelledit, libmtQEX, Qt5 Directory analysis
mtRDC libmtKit, libmtcelledit Random data creator

3.2 Compilation

As outlined above you must build and install the packages in this order:

In all cases you use these commands to compile the programs:

  ./configure
  make

Don't forget to study the makefile and configure script before doing anything. For the complete set of configure options use:

  ./configure --help

The build system I have created uses simple hand built scripts and makefiles. I find this the best way to build the various components of the project. More elaborate systems like GNU Autotools are of no interest to me as they do not solve any problems I have (portability outside the GNU/Linux ecosystem is of no interest to me).

3.3 Installation

Once compilation is completed, use this to install (you must have root user rights):

  make install

You can change the destination directory at this stage if you are creating a package by using:

  make install DESTDIR=/my/chosen/directory/

3.3.1 Program man Pages

All of the programs in the mtCellEdit suite have usage information contained in the associated man page. This can be read in the usual way using the man program, such as this example:

  man cedutils

3.4 Uninstalling

You can uninstall the program and libraries by using (you must have root user rights):

  make uninstall

You will also need to remove any preferences files which are kept in the user directories such as /home/user/.config/mtcelledit/prefs.txt

3.5 Package Management

I aim to get my software working on as many different GNU/Linux systems as possible. To achieve this rationally without testing on hundreds of systems, I work towards compatibility with these system types: Debian, Fedora, and Arch. In doing so I will also achieve compatibility with similar systems.

To achieve these goals as quickly and as easily as possible I use various scripts in the /pkg/ directory to install and test the software (including how I package the software using native package management tools such as pacman, dpkg and rpm). The README.txt file in /pkg/ documents how I do these things, step by step.

The scripts for the different systems all do very different jobs but their interface at the command line is identical. For example to build and install on different platforms using the native package management system you could use:

  ./build_arch.sh --preconf "CC=clang"
  ./build_debian.sh --conf "debug"
  ./build_fedora.sh --conf "--libdir=/usr/lib64"

If your system doesn't use pacman, dpkg, or rpm then you can always use the classic ./configure, make, make install based script using the same arguments:

  ./build_install.sh --preconf "CC=clang" --conf "--libdir=/usr/lib64"

And if you want to remove all of the installed packages from your system, just use one of these:

  ./build_arch.sh remove
  ./build_debian.sh remove
  ./build_fedora.sh remove
  ./build_install.sh remove

Here are the options that are available to these 4 scripts:

flush Clear out the temporary files after a compilation.
remove Remove all installed files from a previous build and install.
--preconf ARG Add environment variable settings such as CC or CFLAGS.
--conf ARG Pass arguments to the configure script such as --libdir or debug.
--bcfile ARG If you want to pass different configure lines to different packages you would use a custom built bcfile. See /pkg/ for a few examples example of this. When using --bcfile the options --preconf and --conf do nothing.

Normally all of the different packages are built in sequence. However you can also pass specific package names to build and install just those items, such as:

  ./build_install.sh libmtkit libmtcelledit mtnetlog

To remove these items you would use:

  ./build_install.sh libmtkit libmtcelledit mtnetlog remove

3.6 Qt Port

I have designed mtCellEdit to work with the Qt toolkit, either version 4.8 or 5.

Qt version 5 is now the default target for mtCellEdit, and is the current version of the Qt platform. It works well on modern and powerful hardware, but it uses rather more resources than Qt4 so will not be the best choice for everyone.

Qt version 4.8 is still used by older systems and has the benefit over Qt 5 as being rather more resource frugal. As always you must consult the configure script help system to ensure you are using the correct settings for things like the system directory you will be installing to.

After installing all of the core library components listed earlier you do the following:

mtQEX

  ./configure --use-qt4
  make
  sudo make install

mtCellEdit

  ./configure --use-qt4
  make
  sudo make install

Menu Icons

Qt 4 sometimes struggles to find the correct icon theme for desktop environments outside GNOME, XFCE, and KDE. This can be fixed by using these command lines:

  gconftool-2 --type string --set /desktop/gnome/interface/icon_theme elementary
  DESKTOP_SESSION=gnome /usr/bin/mtcelledit-qt4

Change "elementary" to the name of your chosen theme. If you use the standard "gnome" theme then this command isn't needed.

If you wish to call this version of mtCellEdit from inside a local .desktop file (located in ~/.local/share/applications) you would use this line:

  Exec=env DESKTOP_SESSION=gnome /usr/bin/mtcelledit-qt4 %f

Preferences File

If you install the Qt4 version on your system with a different binary name as above, it will use a slightly different preferences file to the Qt5 version:

  ~/.config/mtcelledit-qt4/prefs.txt

If you want to share the preferences between the two different programs you would call the program like this:

  mtcelledit-qt4 -prefs ~/.config/mtcelledit-qt5/prefs.txt
