=========  Installing LibRaw ========

I. Installation steps

1. Unpack the distribution file:

 $  tar xzvf LibRaw-0.xx.yy.tar.gz

2. If you wish to use LibRaw demosaic pack(s), unpack them in the same folder:

 $  tar xzvf LibRaw-demosaic-pack-GPL2-0.xx.yy.tar.gz
 $  tar xzvf LibRaw-demosaic-pack-GPL3-0.xx.yy.tar.gz


3. Go to LibRaw folder and run ./configure and make:

 $ cd LibRaw-0.xx.yy
 $ ./configure  [...optional args...]
 $ make

4. install by run make install as root:
 
 $ sudo make install  


II. ./configure options

--enable-openmp
--disable-openmp

  Enable/disable OpenMP support if compiler supports it.
  OpenMP is enabled by default.


--enable-lcms
--disable-lcms

  Enable/disable LCMS color engine support. If enabled, ./configure will try to 
  find lcms library.  Both LCMS-1.x and LCMS-2.x are supported
  LCMS support is enabled by default


--enable-examples
--disable-examples

  Enables/disables examples compilation and installation. Enabled by default


--enable-demosaic-pack-gpl2
--enable-demosaic-pack-gpl2=FOLDERNAME
--enable-demosaic-pack-gpl2=no
--disable-demosaic-pack-gpl2

  Enables/disables support of additional demosaic methods licensed under GPL2
  You need to download and unpack LibRaw-demosaic-pack-GPL2 archive to use 
  this feature.
  ./configure will try to find demosaic pack in:
     
     a) If folder is specified via  --enable-demosaic-pack-gpl2=FOLDERNAME 
        command-line option, then only this folder will be checked.
        
     b) If no folder is specified in --enable-demosaic-pack-gpl2 switch:

          ./LibRaw-demosaic-pack-GPL2 (in LibRaw folder)
         ../LibRaw-demosaic-pack*GPL2* - upper level folder

        If several ../LibRaw-demosaic-pack*GPL2* folders exists in upper level 
        catalog, then ./configure will NOT use any of them due of ambiguity.
        Specify exact folder name in this case using
          --enable-demosaic-pack-gpl2=FOLDERNAME
     
 

--enable-demosaic-pack-gpl3
--enable-demosaic-pack-gpl3=FOLDERNAME
--enable-demosaic-pack-gpl3=no
--disable-demosaic-pack-gpl3
        
        Same as above, but for GPL3-licensed demosaic pack.
