1. BASIC INSTALLATION WITH MANDATORY DEPENDENCIES
=================================================

Installed Linux distribution of choice on platforms i386 or amd-64 (currently Debian-based distributions and Arch-based distributions are covered). You will not need to do this if you
already have a Linux distribution installed. Left this step in to highlight the
Linux distribution the commands below were executed on.

login and open a terminal to get a shell prompt

Download MANDATORY DEPENDENCIES (browser)
-----------------------------------------
Download and install the Qt SDK from http://qt-project.org/
Once that is completed test qmake is ok with: qmake --version (should report 4.9.8 or higher)


DEBIAN-BASED DISTRIBUTION INSTRUCTIONS
--------------------------------------

Install git with:
$ sudo apt-get install git
Said Y to prompt about all git files installed (git-gui et al)

Install FLEX and BISON
----------------------

You will need flex v2.5.9 or later
$ sudo apt-get install bison
$ sudo apt-get install flex
-----------------------------------

ARCH-BASED DISTRIBUTION INSTRUCTIONS
------------------------------------

Install git:
$ sudo pacman -S git

INSTALL FLEX and BISON
----------------------
$ sudo pacman -S flex bison

NEXT STEPS
----------
$ vi gcconfig.pri

Ensure you have the following lines (which are now also in gcconfig.pri.in which has
been updated to reflect the new dependencies in version 3)

QMAKE_LEX  = flex
QMAKE_YACC = bison
win32 {
  QMAKE_YACC = bison --file-prefix=y -t
  QMAKE_MOVE = cmd /c move
  QMAKE_DEL_FILE = rm -f
}

Build!
------
$ make clean
$ qmake
$ make

To compile translation you need QT tool - lrelease
If it is not found using he defaults in src/src.pro then set the full path and filename in gcconfig.pri
QMAKE_LRELEASE = /usr/bin/lrelease

When build first time you get number of error messages on .qm files missing:
    "RCC: Error in 'Resources/application.qrc': Cannot find file 'translations/gc_fr.qm'"
You can ignore these messages for your build. The .qm files will be created during the
build at a later point in time via the "lrelease" command you configured in gcconfig.pri)

If your QT build includes its own local compress libs then you should comment the line below in gcconfig.pri,
otherwise you will need to have the compress libraries installed separately. 
#LIBZ_INCLUDE =
#LIBZ_LIBS    = -lz

You will now have a release3 binary but with none of the release3 dependencies compiled in.
Get latest GOLDEN CHEETAH source files
--------------------------------------
$ mkdir -p ~/Projects/Live
$ cd ~/Projects/Live
$ git clone git://github.com/GoldenCheetah/GoldenCheetah.git
$ cd GoldenCheetah

Configure MANDATORY DEPENDENCIES
--------------------------------
$ cd qwt
$ cp qwtconfig.pri.in qwtconfig.pri
$ cd ../src
$ cp gcconfig.pri.in gcconfig.pri
$ vi gcconfig.pri

Comment out the D2XX_INCLUDE and SRMIO_INSTALL lines for now (put # in first character of the line
to comment out), we will install that in a moment, if we need to.

If you are building for your local host you may find that you get better performance if
compiling with gcc -O3 (tree vectorization can have a significat impact) [or -Ofast]

If so you might like to uncomment:

QMAKE_CXXFLAGS += -O3

Save and exit

$ cd ..

BUILD WITH BASIC CONFIGURATION
$ qmake -recursive
$ make

Congratulations you have now build a basic GoldenCheetah and can run this safely. See below for
optional dependencies you can install to support other features.

ADDING OPTIONAL DEPENDENCIES WHEN BUILDING VERSION 2
====================================================

D2XX - For Powertap downloads via USB
-------------------------------------

Download the FTDI drivers from http://www.ftdichip.com/Drivers/D2XX.htm (e.g. I used Linux 
64-bit drivers from http://www.ftdichip.com/Drivers/D2XX/Linux/libftd2xx1.0.4.tar.gz)

Extract into your home directory (I put mine into ~/Projects/ with archive manager which
created a sub-directory ~/Projects/libftd2xx1.0.4

$ cd src
$ vi gcconfig.pri

Uncomment the D2XX_INCLUDE entry and make it match (my home is /home/markl)
D2XX_INCLUDE = /home/markl/libftd2xx1.0.4

Make clean is needed if you have previouslt built, since source files examine #defines before
including this feature. You can skip it if you know why ;)
$ make clean
$ qmake
$ make

You now have D2XX support, for downloading from a PT via a USB cradle.

SRMIO - For SRM powercontrol V downloads via Serial
---------------------------------------------------

$ cd ~/Projects
$ git clone git://github.com/rclasen/srmio srmio
$ cd srmio

Get automake and tools, if you don't already have them (I didn't after a fresh install)
$ sudo apt-get install automake
$ sudo apt-get install libtool

Generate the configure script, run it, build and install srmio
$ sh genautomake.sh
$ ./configure
$ make
$ sudo make install

Lets go config GC and build with SRMIO
$ cd ~/Projects/Live/GoldenCheetah/src
$ vi gcconfig.pri

Uncomment the SRMIO_INSTALL and replace with the target used from srmio install:
SRMIO_INSTALL = /usr/local/

At the bottom of gcconfig.pri you will see the include directory should reference from
the base install location (/usr/local) make sure it says:

SRMIO_INCLUDE = $${SRMIO_INSTALL}/include
SRMIO_LIB = $${SRMIO_INSTALL}/lib/libsrmio.a

Make clean is needed if you have previouslt built, since source files examine #defines before
including this feature. You can skip it if you know why ;)
$ make clean
$ qmake
$ make

You now have SRM support built in.

LIBKML - For export to Google Earth
-----------------------------------

You will need Google Earth 5.2 or later and therefore libkml that supports this. Unfortunately at the time of writing
the officially packaged libkml is too old, so you will need to install from source, which means you will need to have
subversion installed and expat. You may be able to use the currently packaged libkml with

$ sudo apt-get install libkml-dev

if this does not work you will need to build from source:

    $ sudo apt-get install subversion
    $ sudo apt-get install expat libexpat1 libexpat1-dev

    Once svn is installed you can grab the libkml source and configure build etc:
    $ cd ~/Projects
    $ svn checkout http://libkml.googlecode.com/svn/trunk/ libkml
    $ cd libkml

    You will need automake and friends (see SRMIO above)
    $ sh autogen.sh
    $ ./configure
    $ make
    $ make install
    $ sudo make install

    If you get errors about use of 'long long' then edit:
    - src/kml/{convenience,dom,engine,regionator,xsd}/Makefile
    - examples/{engine,gpx,gx,hellonet,helloworld,regionator,xsd}/Makefile
    - and look for the flag -pedantic and remove it. I got this on Linux 64bit builds ymmv.

Once libkml is installed and built:

$ cd ~/Projects/Live/GoldenCheetah/src
$ vi gcconfig.pri

Ensure KML_INSTALL=/usr/local

Make clean is needed if you have previously built, since source files examine #defines before
including this feature. You can skip it if you know why ;)
$ make clean
$ qmake
$ make

You can now export rides to Google Earth kml format.

ADDING OPTIONAL DEPENDENCIES WHEN BUILDING VERSION 3
====================================================


NOTE: When you run version 3 it will refresh ride metrics and CP files -- this only occurs the
      first time it runs (and will refresh only rides that change after that). I find it is best
      to import ride files once your build where you want it. i.e. don't import until you have
      got all your dependencies sorted.

NOTE: To reduce the dependencies on 'dormant' code there are a number of new pieces of source
      that are included in the release3 tree. Notably; qtsoap from qt-solutions, since they
      work but are likely to be archived and deprecated. If and when that happens we may well
      adopt whatever classes Trolltech introduce.


LIBICAL - Diary integration with Google or MobileMe calendars
-------------------------------------------------------------

$ cd ~/Projects/Live/GoldenCheetah/src

$ sudo apt-get install libical-dev
$ vi gcconfig.pri

ICAL_INSTALL=/usr/include
ICAL_LIBS=-lical

Since the src.pro wants ICAL installed in a different place we need to hack it, *** this will
be fixed shortly ***

$ vi src.pro

Comment out the ICAL_LIBS entry:

#ICAL_LIBS = $${ICAL_INSTALL}/lib/libical.a

$ make clean
$ qmake
$ make

You should now have diary functions.

NOTE: That upload to MobileMe and Google requires a functioning https lib in QT. Depending
      upon the version installed this might not be the case and will need to be built and
      configured -- this is beyond the scope of this walkthough. Sorry.

LIBVLC - Video playback in Realtime (Experimental)
--------------------------------------------------

You will need libvlc 1.1.9 or higher (1.1.8 is ok but will segv on exit)
$ sudo apt-get install libvlc-dev

$ vi gcconfig.pri

Comment out VLC_INSTALL and it should read:

VLC_INSTALL = /usr/include/vlc/

$ make clean
$ qmake
$ make
