### IceWM Dependencies

#### Required

CMake-4.2.3, imlib2-1.12.6, and a graphical environment

#### Optional

asciidoc-10.2.1 (for regenerating the HTML documentation), FriBidi-1.0.16 (for languages written right to left), librsvg-2.61.4, libao-1.2.0, libsndfile-1.2.2, alsa-lib-1.2.15.3 (for the experimental icesound program), and gdk-pixbuf-xlib

## Installation of IceWM

Install IceWM by running the following commands:

    mkdir build &&
    cd    build &&

    cmake -D CMAKE_INSTALL_PREFIX=/usr \
          -D CMAKE_BUILD_TYPE=Release  \
          -D CFGDIR=/etc               \
          -D ENABLE_LTO=ON             \
          -D DOCDIR=/usr/share/doc/icewm-4.0.0  \
          .. &&
    make

This package does not have a working test suite.

Now, as the `root` user:

    make install

This package creates two `.desktop` files in the `/usr/share/xsessions/` directory. Both are not needed in a BLFS system, so prevent the extra file showing up as an option in a display manager. As the `root` user:

    rm -v /usr/share/xsessions/icewm.desktop

## Command Explanations

`-D ENABLE_LTO=ON`: This option enables Link Time Optimization and is required for this package.

## Configuring IceWM

### Config Files

`~/.icewm/keys`, `~/.icewm/menu`, and `~/.icewm/preferences`, and `~/.icewm/toolbar`, and `~/.icewm/winoptions`. The default versions are installed in `/usr/share/icewm/` and will be used if you have not copied them to `~/.icewm`.

### Configuration Information

If IceWM is the only Window Manager you want to use, you can start it with an `.xinitrc` file in your home folder. Be sure to backup your current `.xinitrc` before proceeding.

    echo icewm-session > ~/.xinitrc

Now create the IceWM configuration files:

    mkdir -pv ~/.icewm                                      &&
    cp -v /usr/share/icewm/keys ~/.icewm/keys               &&
    cp -v /usr/share/icewm/menu ~/.icewm/menu               &&
    cp -v /usr/share/icewm/preferences ~/.icewm/preferences &&
    cp -v /usr/share/icewm/toolbar ~/.icewm/toolbar         &&
    cp -v /usr/share/icewm/winoptions ~/.icewm/winoptions

You can now edit these files to meet your requirements. In particular, review the `preferences` file. You can use Logout -> Restart-IceWM on the main menu to load your changed preferences, but changes to the background only take effect when IceWM is started.

At this point you can either modify the traditional menu files to suit your requirements, or use the newer icewm-menu-fdo described later.

The syntax of the menus is explained in the help files, which you can access by running help from the menu, but some of the detail is out of date and the default selections in the menus (a few old applications on the main menu, everything else on the Programs menu) will benefit from being updated to meet your needs. The following examples are provided to encourage you to think about how you wish to organise your menus. Please note the following:

- If a program listed in the menu has not been installed, it will not appear when the menu is displayed. Similarly, if the program exists but the specified icon does not, no icon will be displayed in the menu.

- The icons can be either `.xpm` or `.png` files, and there is no need to specify the extension. If the icon is located in the "library" (`/usr/share/icewm/icons`) there is no need to specify the path.

- Most programs are in sub-menus, and the main menu will always append entries for `windows, help, settings, logout` at the bottom.

- An icon for firefox was copied to the library directory and given a meaningful name. The icon for xine is `xine.xpm` which was installed to a pixmap directory.

- The default toolbar is not altered.

If you wish to use this traditional method, there are more examples in previous releases of this book (e.g. BLFS-7.8).

Alternatively, you can create a menu which conforms to the FDO Desktop Menu Specifications, where programs can be found because they have a .desktop file in the XDG_DATA_HOME or XDG_DATA_DIR directories. Unlike most windowmanagers, icewm does not search for programs when the menu is invoked, so if you take this route you will need to rerun the following command after installing or removing programs:

    icewm-menu-fdo >~/.icewm/menu

If you wish to put icons on your desktop, you will need to install a program such as rox-filer which provides a pinboard. If you do that you will no longer be able to access the menu by right-clicking on the desktop, you will have to use the IceWM button. To ensure that the rox pinboard is running, the following commands will put it in the startup file:

    cat > ~/.icewm/startup << "EOF"
    rox -p Default &
    EOF &&
    chmod +x ~/.icewm/startup

### Tip

There are a number of keyboard shortcuts in IceWM:

- Ctrl + Alt + F`N` : go to `tty`N``.

- Ctrl + Alt + `N` : go to desktop number `N`

- Ctrl + Alt + Space : open a box on the taskbar where you can key in the name of an application and run it.
