DESCRIPTION

    SpaceFM is a multi-panel tabbed file manager with built-in VFS, udev-based
    device manager, customizable menu system, and bash integration.


PACKAGES

    Find or add packages, forum threads, and other info for your distro:
        https://github.com/IgnorantGuru/spacefm/wiki/Distros

    For other distros:
        See INSTALLER below

    NOTE: Enabling kernel polling is recommended after installing SpaceFM.  See
          the ENABLE KERNEL POLLING section below or visit:
    http://ignorantguru.github.io/spacefm/spacefm-manual-en.html#devices-kernpoll


INSTALLER

    A self-extracting installer is available (spacefm-x.x.x-installer.sh):
        https://github.com/IgnorantGuru/spacefm/tree/pkg
            (To save a file, click on its filename and click 'View Raw')

    The installer requires the build dependencies listed below in BUILD.  If
    any dependencies are missing, examine the error, install missing packages,
    and try again.

    The installer MUST be run in a terminal.  It automatically builds and
    installs.  Run it like this:

        bash spacefm-x.x.x-installer.sh

    or to see options:

        bash spacefm-x.x.x-installer.sh --help

    To reinstall or upgrade, just run the latest installer again.

                      libstartup-notification0 libstartup-notification0-dev
                      dbus libdbus-1-3 libdbus-1-dev

    configure will report anything missing when you run it as shown below.

2)  Use these commands to download the SpaceFM tarball and build:

        # Download & Extract
        mkdir /tmp/spacefm-build && cd /tmp/spacefm-build
        wget -O spacefm.tar.gz https://github.com/IgnorantGuru/spacefm/tarball/master
        tar xzf spacefm.tar.gz
        cd IgnorantGuru-spacefm-*

        # Build & Install
        ./configure
        make -s
        sudo make install
        sudo update-mime-database /usr/local/share/mime > /dev/null
        sudo update-desktop-database -q
        sudo gtk-update-icon-cache -q -t -f /usr/local/share/icons/hicolor
        sudo gtk-update-icon-cache -q -t -f /usr/local/share/icons/Faenza

        # Remove Temporary Files
        cd / && rm -rf /tmp/spacefm-build

    NOTES:
    a) If configure reports missing dependencies, install them and run
       configure again before proceeding to make.

    b) Enabling kernel polling is recommended after installing SpaceFM:
       http://ignorantguru.github.io/spacefm/spacefm-manual-en.html#devices-kernpoll

    c) SpaceFM supports ktsuss, gksu, gksudo, gnomesu, kdesu, and xdg-su.
       To build with an additional custom su program ('/usr/bin/mysu' in this
       example), add:
          --with-preferable-sudo=/usr/bin/mysu   # to the configure command


BUILD GTK3

The GTK3 build of SpaceFM uses the newer GTK libraries.  BE SURE to use a
GTK3 theme which supports your CURRENT version of GTK3 (no theme warnings
should appear when spacefm is run in a terminal), or use adwaita.  Use of GTK3
without any theme is NOT recommended.

PACKAGERS:  Due to the unfinished and changing nature of GTK3, some users
may prefer the GTK2 build.  Please consider providing both spacefm-gtk2 and
spacefm-gtk3 packages for your users.

1)  Install required build dependencies (below are Debian package names -
    packages names on your distro may vary but should be similar):

        autotools-dev bash build-essential desktop-file-utils libc6 libcairo2
        libglib2.0-0 libglib2.0-dev libgtk-3-0 libgtk-3-dev libgtk-3-bin
        libpango1.0-0 libx11-6 shared-mime-info intltool pkg-config fakeroot
        libudev0 (>=143) libudev-dev

    Also Recommended: udevil|pmount|udisks eject lsof wget ktsuss|gksu|kdesu

        wget -O spacefm.tar.gz https://github.com/IgnorantGuru/spacefm/tarball/master
        tar xzf spacefm.tar.gz
        cd IgnorantGuru-spacefm-*

        # Build & Install
        ./configure --with-gtk3
        make -s
        sudo make install
        sudo update-mime-database /usr/local/share/mime > /dev/null
        sudo update-desktop-database -q

       To build with an additional custom su program ('/usr/bin/mysu' in this
       example), add:
          --with-preferable-sudo=/usr/bin/mysu   # to the configure command


BUILD HAL

Device features are extremely limited with HAL.  Use of this build is only
recommended if udev is not installed.  SpaceFM HAL support is no longer
actively developed, yet please report any build problems.

1)  Install required build dependencies (below are Debian package names -
    packages names on your distro may vary but should be similar):

        autotools-dev bash build-essential desktop-file-utils libc6 libcairo2
        libglib2.0-0 libglib2.0-dev libgtk2.0-0 (>=2.18) libgtk2.0-dev
        libgtk2.0-bin libpango1.0-0 libx11-6 shared-mime-info intltool
        pkg-config fakeroot
        hal libhal-dev libhal-storage-dev libhal-storage1 libhal1
        dbus libdbus-1-3 libdbus-1-dev libdbus-glib-1-2 libdbus-glib-1-dev

    Also Recommended: wget ktsuss|gksu libstartup-notification0
                      libstartup-notification0-dev

    configure will report anything missing when you run it as shown below.

2)  Use these commands to download the SpaceFM tarball and build:

        # Download & Extract
        mkdir /tmp/spacefm-build && cd /tmp/spacefm-build
        wget -O spacefm.tar.gz https://github.com/IgnorantGuru/spacefm/tarball/master
        tar xzf spacefm.tar.gz
        cd IgnorantGuru-spacefm-*

        # Build & Install
        ./configure --enable-hal
        make -s
        sudo make install
        sudo update-mime-database /usr/local/share/mime > /dev/null
        sudo update-desktop-database -q
        sudo gtk-update-icon-cache -q -t -f /usr/local/share/icons/hicolor
        sudo gtk-update-icon-cache -q -t -f /usr/local/share/icons/Faenza

        # Remove Temporary Files
        cd / && rm -rf /tmp/spacefm-build

    NOTES:
    a) If configure reports missing dependencies, install them and run
       configure again before proceeding to make.

    b) Enabling kernel polling is recommended after installing SpaceFM:

    c) SpaceFM supports ktsuss, gksu, gksudo, gnomesu, kdesu, and xdg-su.
       To build with an additional custom su program ('/usr/bin/mysu' in this
       example), add:
          --with-preferable-sudo=/usr/bin/mysu   # to the configure command


BUILD NEXT

The git 'next' branch of SpaceFM is a work in progress which eventually becomes
the next release version.  To build from this branch, install the required
build dependencies listed above for your build, then:

    # Download & Extract
    mkdir /tmp/spacefm-next && cd /tmp/spacefm-next
    wget -O spacefm-next.tar.gz https://github.com/IgnorantGuru/spacefm/tarball/next
    tar xzf spacefm-next.tar.gz
    cd IgnorantGuru-spacefm-*

    # Build & Install
    ./configure
    make -s
    sudo make install
    sudo update-mime-database /usr/local/share/mime > /dev/null
    sudo update-desktop-database -q
    sudo gtk-update-icon-cache -q -t -f /usr/local/share/icons/hicolor
    sudo gtk-update-icon-cache -q -t -f /usr/local/share/icons/Faenza

    # Remove Temporary Files
    cd / && rm -rf /tmp/spacefm-next


BUILD DEBUG

If SpaceFM crashes or hangs on your system, you can help to correct this
problem by reporting it, including a full backtrace.

IF you are using Arch Linux, you can perform step 2 below, then install the AUR
spacefm-git package, which enables debugging.

For other distros:

1)  Install build dependencies for your build (see BUILD sections above).

2)  Install the 'gdb' GNU Debugger, and debugging symbols for gtk.  For example
    on Debian, this is done like this (packages on other distros should have
    similar names):

    apt-get install gdb libc6-dbg libglib2.0-0-dbg libgtk2.0-0-dbg librsvg2-dbg

3)  Use these commands to download the SpaceFM tarball and build:

        # Download & Extract
        mkdir /tmp/spacefm-build && cd /tmp/spacefm-build
        # substitute 'next' for 'master' below if next branch is desired
        wget -O spacefm.tar.gz https://github.com/IgnorantGuru/spacefm/tarball/master
        tar xzf spacefm.tar.gz
        cd IgnorantGuru-spacefm-*

        # Build & Install
        CFLAGS='-ggdb3 -O1' STRIP='!strip' ./configure  # pass any options here
        make -s
        sudo make install
        sudo update-mime-database /usr/local/share/mime > /dev/null
        sudo update-desktop-database -q
        sudo gtk-update-icon-cache -q -t -f /usr/local/share/icons/hicolor
        sudo gtk-update-icon-cache -q -t -f /usr/local/share/icons/Faenza

        # Remove Temporary Files
        cd / && rm -rf /tmp/spacefm-build

4)  Run spacefm with the debugger:

        gdb /usr/local/bin/spacefm

    In gdb, enter 'run' at the prompt.  SpaceFM will start.  When the crash
    occurs, gdb will freeze SpaceFM.  If SpaceFM hangs, press Ctrl-C in gdb to
    interrupt it, or run 'killall -s KILL spacefm' in another terminal.

5)  In the terminal running gdb enter 'bt full'.  Provide the output with your
    detailed bug report at https://github.com/IgnorantGuru/spacefm/issues

    NOTE: When SpaceFM is built this way, it may run more slowly and use more
    memory.  Once you are done debugging, be sure to install a normal
    (optimized) build.


CREATE DEB PACKAGE

To build a deb file of SpaceFM on your Debian-based distro:

1)  Install build dependencies for your build (see above), plus debhelper.

2)  Use these commands to download and extract the SpaceFM tarball (be sure to
    USE A TMP BUILD PATH THAT DOES NOT CONTAIN SPACES):

        mkdir /tmp/spacefm-build && cd /tmp/spacefm-build   # no spaces in path
        # Note: you can change "master" to "next" if you want the next branch:
        wget -O spacefm.tar.gz https://github.com/IgnorantGuru/spacefm/tarball/master
        tar xzf spacefm.tar.gz
        cd IgnorantGuru-spacefm-*

3)  Move the distros/debian directory into the source directory:

        mv distros/debian .

    NOTE: For newer Debian versions, some adjustments to the control file
    (dependencies) may be necessary, or use official Debian packages.

4)  IF GTK3 support IS desired:

        cp debian/control-gtk3 debian/control
        cp debian/rules-gtk3 debian/rules
        sed -i 's/^spacefm \(.*\)/spacefm-gtk3 \1/' debian/changelog

5)  IF hal support IS desired (cannot be used with GTK3 unless you edit rules):

        cp debian/control-hal debian/control
        cp debian/rules-hal debian/rules
        sed -i 's/^spacefm \(.*\)/spacefm-hal \1/' debian/changelog

6)  Build package:  (the package files will appear in the parent directory)

        dpkg-buildpackage -b -uc
        cd .. && rm -rf IgnorantGuru-spacefm-* spacefm.tar.gz

7)  To install the package you built:

        dpkg -i spacefm*.deb


UNINSTALL

If you installed from a package, use your package manager to remove SpaceFM.
Otherwise, run these commands AS ROOT:

    rm /usr/local/bin/spacefm /usr/local/bin/spacefm-auth
    rm -r /usr/local/share/spacefm
    rm /usr/local/share/pixmaps/spacefm.png
    rm /usr/local/share/pixmaps/spacefm-*.png
    rm /usr/local/share/icons/hicolor/*/apps/spacefm.png
    rm /usr/local/share/icons/hicolor/*/apps/spacefm-*.png
    rm /usr/local/share/icons/Faenza/apps/48/spacefm.png
    rm /usr/local/share/icons/Faenza/apps/48/spacefm-*.png
    rm /usr/local/share/locale/*/LC_MESSAGES/spacefm.mo
    rm /usr/local/share/applications/spacefm*.desktop
    rm /usr/local/share/mime/packages/spacefm-mime.xml
    update-mime-database /usr/local/share/mime > /dev/null
    update-desktop-database -q
    gtk-update-icon-cache -q -t -f /usr/local/share/icons/hicolor


ENABLE KERNEL POLLING

    You may need to enable kernel polling for device media changes to be
    detected by SpaceFM.  For example, if you insert a CD and SpaceFM still
    says 'no media', this is a symptom that kernel polling is not enabled.

    Kernel polling is a newer feature of the Linux kernel and udev, so some
    distros don't yet have it enabled by default.  To use kernel polling,
    your Linux kernel may need to be 2.6.38 or newer, and udev may need to
    be version 173 or newer.

    TO DETERMINE IF KERNEL POLLING IS ENABLED:

        cat /sys/module/block/parameters/events_dfl_poll_msecs
        cat /sys/block/sr0/events_poll_msecs

    If you get 0 or -1 from both of those commands, kernel polling may be
    disabled.

    TO ENABLE KERNEL POLLING PERMANENTLY (survives a reboot), add the
    following command to your /etc/rc.local file (anywhere before the
    'exit' line in that file):

        echo 2000 > /sys/module/block/parameters/events_dfl_poll_msecs

    Any number between 2000 and 5000 (milliseconds) should be reasonable -
    the higher 5000 means poll every 5 seconds, which is less overhead but
    a little slower.

    OR pass this option to the kernel boot command line in grub:

        block.events_dfl_poll_msecs=2000

    OR add a udev rule to enable kernel polling on removable devices:

        echo 'ACTION=="add", ATTR{removable}=="1", \
              ATTR{events_poll_msecs}=="-1", ATTR{events_poll_msecs}="2000"' \
              > /etc/udev/rules.d/61-removable-storage-polling.rules

    A reboot will be required for the above changes to take effect, or...

    TO ENABLE KERNEL POLLING TEMPORARILY AND IMMEDIATELY, enable common
    polling for the block module:

        sudo bash -c 'echo 2000 > /sys/module/block/parameters/events_dfl_poll_msecs'

    OR you can enable polling just for a single device like this (/dev/sr0
    in this example):

        sudo bash -c 'echo 2000 > /sys/block/sr0/events_poll_msecs'

    This change should be immediate - media will be detected.  However, the
    above change will be lost when you reboot.
