Requirements
-----------
To build Cego, you need the following library packages available from www.lemke-it.com:
   
   lfc-1.4.1.tar.gz
   lfcxml-1.0.27.tar.gz

Furthermore, you need the GNU readline library available via http://tiswww.case.edu/php/chet/readline/rltop.html    

Tested platforms and compliers
----------------------------
Cego has been successfully tested on

       Solaris SPARC and x86 ( primary development platform ( x86) )
       Linux ( secondary )
       Mac OS X ( secondary )
       Windows/MinGW/MSYS ( compiled and tested )
       FreeBSD ( compiled and tested )
       HP-UX  ( compiled, but not heavy tested )
       
using GNU C++ compiler or Forte C++ ( Solaris )

Installation
------------
Run the configure script with the following options

    $ ./configure --prefix=<prefix-dir>

where prefix-dir is the base directory of the previous installed base and xml libraries.
For 64bit compile, you have to set the CFLAGS variable

    $ ./configure --prefix=<prefix-dir> CFLAGS=-m64 LDFLAGS=-m64

where -m64 is the valid compile option vor GNU gcc.

For Forte C compiles ( Sun Solaris ), you should specify
 
    $ ./configure --prefix=<prefix-dir> CFLAGS=-m64 LDFLAGS=-m64
 
Please note : For 64bit compile, you also need appropriate 64bit compiled versions of libBase,
libXML and the readline library

For multithreaded performance reasons, use for Solaris compiles additional compiler flags ( Forte CC )
and the the libumem library ( libumem is highly recommended ) 

On a M5000 ( UltraSPRC VII ), I used the following flags 

    $ ./configure --prefix=<prefix-dir> CFLAGS="-m64 -mt -KPIC -xprefetch=yes -xarch=sparcfmaf -fma=fused 
      		  			-xchip=sparc64vi" LDFLAGS="-xarch=sparcfmaf -lumem"

Please note: On an AMD Athlon(tm) 64 Processor 3800+ Socket 939 with Solais x86, the linkage 
of the libumem slows down application performance of about 20% 

On FreeBSD 8.1, cego has been sucessfully compiled using the clang++ compiler with the following options
With cego 2.10.0, code adaptions have been taken place to avoid compiler warnings

   $ export CC=clang 
   $ export CXX=clang++
   $ ./configure --prefix=<prefix-dir>

Run make

    $ make

This builds the Cego executable programs. You can install
the resulting files with the install command

    $ make install

If compiled  succesful, you can check the database by typing 

    $ make basecheck
    ( cd samples/chkdb; ./checkSQL; ./expImpCheck 10000)

This builds up a sample database and performs several checks on the database.
If succesful, the output should appear as listed above

More sophisticated checks can be performed by running the quality gate checks

    $ make gatecheck
    
For logging, a status table is written and printed out at the end, when all quality gates have been passed.
If succesful, all checks should be marked as ok, otherwise an error indicates the failed gate checks.

A C++ programming sample can be build with

   $ make cgplustest 

A C-Wrapper ( to link with plain C ) programming sample can be build with

   $ make cgwtest 

Have fun !
