  This script can be used by developers of MySQL, early adopters wanting 
  to try out early versions of MySQL before binary versions are 
  available, anyone needing a version with a special patch included that 
  needs to be built from source code, or anyone else wanting to exercise 
  full control over the MySQL build process.

  This help text is targeted towards those that want to debug and test 
  MySQL using source code releases. If you have downloaded a source code 
  release and simply want to build a usable binary, you should read the 
  --sysadmin-help instead.

  The script is also designed to be used by anyone receiving a source 
  code release of MySQL Cluster Carrier Grade Edition. The default
  behaviour is to build the standard MySQL Cluster Carrier Grade Edition
  package. Three environment variables can be used to change the 
  default behaviour:

  MYSQL_DEVELOPER
    Defining this variable is similar to setting the --developer flag
  MYSQL_DEVELOPER_PACKAGE=package
    Defining this variable is similar to setting the --package=* 
    variable
  MYSQL_DEVELOPER_DEBUG
    Defining this variable sets the --with-debug flag

  Options used with this script always override any default behaviour. 
  The default package is MySQL Cluster Carrier Grade (standard) Edition. 
  For developers, the default package is MySQL Cluster Carrier Grade 
  Extended Edition.

  More information for developers can be found in --help, 
  --sysadmin-help, and --extended-help.

  The most common usage for developers is to set the three variables 
  mentioned previously and then simply to run the script without any 
  additional parameters, using them only when needing to change some 
  things like not requiring debug build. If some of these environment 
  variables have already been set, you can use the corresponding options 
  to unset them and reverse their effects.

  This script can be used to build MySQL Cluster Carrier Grade Edition
  based on a source code release you received from MySQL. It can also
  be used to build many variants other variants of MySQL, in particular
  various performance-optimised versions of MySQL.

  It is assumed that you are building on a computer which is of the 
  same type as that on which you intend to run MySQL/MySQL Cluster.

  The simplest possible way to run this script is to allow it to use the 
  built-in defaults everywhere, invoking it simply as (from top-level
  MySQL directory):

  shell> BUILD/build_mccge.sh

  This performs the following operations:
    1) Detects the operating system. Currently, Linux, FreeBSD, Solaris 
      8/9/10/11, and Mac OS X are supported by this script.
    2) Detect the type of CPU being used. Currently supported processors 
      are: x86 for all supported operating systems, Itanium for Linux 
      with GCC, and x86 + SPARC for Solaris using the Forte compiler and
      finally x86 on Linux using the Intel compiler.
    3) Invokes the GCC compiler.
    4) Builds a set of MySQL/MySQL Cluster binaries; for
      more information about these, see --extended-help.
    5) Default compiler is always gcc.
  
  The default version assumes that you have a source code tarball from 
  which you are building, and thus autoconf and automake do not need to 
  be run. If you have downloaded a BitKeeper tree then you should read 
  --developer-help.

  If you are building MySQL/MySQL Cluster for commercial 
  use then you need to set the --commercial flag to ensure that the 
  commercial libraries are compiled in, rather than the GPL-only 
  libraries. The default is to build a GPL version of MySQL Cluster 
  Carrier Grade Edition.

  If your building on a Solaris SPARC machine and you want to compile
  using SunStudio you must set 
  --compiler=forte; if you want to build using the Intel compiler on 
  Linux, you need to set --compiler=icc. If you want to use the AMD
  compiler Open64 set --compiler=open64.

  A synonym for forte is SunStudio, so one can also use
  --compiler=SunStudio.

  If you want to make sure that a 64-bit version is built then you 
  should add the flag --64. This is always set on Solaris machines and 
  when check-cpu is able to discover that a 64-bit CPU is being used. If 
  you want to ensure that a 32-bit binary is produced, use --32 instead.

  If you need the binaries to be installed in a different location from 
  /usr/local/mysql, then you should set --prefix to point to where you
  want the binaries installed.

  Using a data directory other than the default (PREFIX/data) can be 
  done when starting the MySQL Server, or by invoking this script with 
  the --datadir option.

  If you want your binaries stripped of surplus debug or other 
  information, use the --strip option.

  If you want debug information in the binary (for example, to be
  able to send gdb core dumps to MySQL Support), then you should add the 
  flag --with-debug; if you want a production build with only debugging 
  information in the binary then use --debug.

  If your aim is not to build MySQL Cluster Carrier Grade Edition, you 
  can also use this script to build MySQL Classic and MySQL Enterprise Pro 
  versions; see the --extended-help for descriptions of these packages.

  Extended help text for this script:
  -----------------------------------
  This script is intended to make it easier for customers using MySQL
  Cluster Carrier Grade Edition, customers using performance-optimised
  MySQL versions and developers to build the product from source on 
  these platforms/compilers: Linux/x86 (32-bit and 64-bit) (either using
  gcc or icc), Linux Itanium, Solaris 8,9,10 and 11 x86 and SPARC using
  gcc or SunStudio and MacOSX/x86/gcc.

  The script automatically detects CPU type and operating system; The
  default compiler is always gcc.

  To build on other platforms you can use the --print-only option on a
  supported platform and edit the output for a proper set of commands on
  the specific platform you are using. MySQL also provides custom builds
  for any type of platform that is officially supported for MySQL
  Cluster. For a list of supported platforms, see
  http://www.mysql.com/support/supportedplatforms/cluster.html.

  Using the --package option, it is also possible to build a "classic"
  version of MySQL having only the MyISAM storage engine, a "Pro"
  package including all storage engines and other features except MySQL
  Cluster, and an "extended" package including these features plus MySQL
  Cluster (this is the default if the --developer option is used).

  Different MySQL storage engines are included in the build, depending
  on which --package option is used. The comment and version strong
  suffix are also set according to the package selected.

  --package=cge
    storage engines:
      ARCHIVE, BLACKHOLE, CSV, FEDERATED, MYISAM, NDB
      (All storage engines except InnoDB)
    comment: MySQL Cluster Carrier Grade Edition GPL/Commercial version 
             built from source
    version string suffix: -cge

  --package=extended
    storage engines:
      ARCHIVE, BLACKHOLE, CSV, FEDERATED, MYISAM, INNODB, NDB
      (All storage engines)
    comment: MySQL Cluster Carrier Grade Extended Edition GPL/Commercial 
             version built from source
    version string suffix: -cge-extended

  --package=pro
    storage engines:
      ARCHIVE, BLACKHOLE, CSV, FEDERATED, INNODB, MYISAM
      (All storage engines except NDB)
    comment: MySQL Pro GPL/Commercial version built from 
             source
    version string suffix: [none]

  --package=classic
    storage engines: CSV, MYISAM
    comment: MySQL Classic GPL/Commercial version built 
             from source
    version string suffix: [none]

  All packages except Classic include support for user-defined
  partitioning. All packages include support for Performance
  Schema.

  If --with-debug is used, an additional "-debug" is appended to the
  version string.

  --commercial
    This flag prevents the use of GPL libraries which cannot be used
    under a commercial license, such as the readline library.

  --developer
    This option changes a number of things to make the version built
    more appropriate to the debugging and testing needs of developers. 
    It changes the default package to "extended". It also changes the 
    default warning mode from "none" to "normal", which allows an 
    extensive list of warnings to be generated.

  --error-inject
    This flag is used only when the --developer option is also used, and
    enables error injection in both the MySQL Server and in MySQL
    Cluster data nodes.

  The following is a list of the default configure options used for all
  packages:

  --prefix: /usr/local/mysql (can be overridden)

  --libexecdir: <prefix>/bin (can be overridden)

  --localstatedir: <prefix>/data, unless --datadir is used, in which
    case it defaults to <datadir>/data (can be overridden by setting
    --localstatedir explicitly).

  --enable-local-infile: Enable use of the LOAD DATA FROM  LOCAL INFILE
    command (cannot be overridden).

  --enable-thread-safe-client: Enable the multi-threaded mysql client
    library (cannot be overridden).

  --with-big-tables: Enable use of tables with more than 4G rows (cannot
    be overridden).

  --with-extra-charsets=all: Enable use of all character sets supported
    by MySQL (cannot be overridden).

  --with-ssl: Enable use of yaSSL library included in the MySQL source
    if possible (GCC and same CC and CXX).
    (cannot be overridden).

  --with-pic: Build all binaries using position independent assembler
    to avoid problems with dynamic linkers (cannot be overridden).

  --without-example-engine: Ensure that the example engine isn't built,
    it cannot do any useful things, it's merely intended as documentation.
    (cannot be overridden)

  --with-csv-storage-engine: Ensure that the CSV storage engine is
    included in all builds. Since CSV is required for log tables in
    MySQL 5.1, this option cannot be overridden.

    (Note that MyISAM support is always built into the MySQL Server; the
    server *cannot* be built without MyISAM.)

  --with-mysqld-ldflags=-static
  --with-client-ldflags=-static
    Ensures that binaries for, respectively, the MySQL server and client
    are built with static libraries except for the system libraries,
    which use dynamically loaded libraries provided by the operating
    system. Building with --developer sets these to all-static instead, 
    to build everything statically.

  In addition there are some configure options that are specific to
  Linux operating systems:

  --enable-assembler
    Include assembler code optimisations for a number of mostly string
    methods. Used for x86 processors only.

  Neither of the preceding options can be disabled.

  MySQL Cluster Carrier Grade edition also adds the following options
  (also used by the extended package):

  --with-ndbcluster
    Include the NDB Cluster storage engine, its kernel, management
    server, and client, as well as support for the NDB and MGM APIs.

  --without-ndb-debug
    Do not include specific NDB debug code, not even in debug versions
    (cannot be overridden).

  Package-specific options:
  -------------------------
  --with-innodb
    Specifically included in the "pro" and "extended" packages, and not 
    in any of the others.

  --with-comment
    Sets the comment for the MySQL version, by package, as described
    above.

  --with-server-suffix
    Sets the server suffix on the MySQL version, by package, as
    described above.

  Other options used:
  -------------------
  --with-readline
    Use the GPL readline library for command editing functions; not
    available with commercial packages.

  --with-libedit
    Use the BSD licensed library for command editing functions; used for
    commercial packages.

  --with-zlib-dir=bundled
    Use the zlib package bundled with MySQL.

  --with-mysqld-libs=-lmtmalloc
    Used on Solaris to ensure that the proper malloc library is used.
    Investigations have shown mtmalloc to be the best choice on Solaris,
    also umem has good performance on Solaris but better debugging
    capabilities.

  Compiler options:
  -----------------

    This section describes the compiler options for each of the different
    platforms supported by this script.

    The --fast option adds -mtune=cpu_arg to the C/C++ flags (provides
    support for Nocona, K8, and other processors), this option is valid
    when gcc is the compiler.

    Use of the --debug option adds -g to the C/C++ flags.

    In all cases it is possible to override the definition of CC and CXX
    by calling the script as follows:
    CC="/usr/local/bin/gcc" CXX="/usr/local/bin/g++" BUILD/build_mccge.sh

  Feedback profiler on gcc
  ------------------------
  Using gcc --generate-feedback=path causes the following flags to be added
  to the compiler flags.

  --fprofile-generate
  --fprofile-dir=path

  Using gcc with --use-feedback=path causes the following flags to be added
  to the compiler flags. --fprofile-correction indicates MySQL is a multi-
  threaded application and thus counters can be inconsistent with each other
  and the compiler should take this into account.

  --fprofile-use
  --fprofile-dir=path
  --fprofile-correction

  Feedback compilation using Open64
  ---------------------------------

  Using Open64 with --generate-feedback=path causes the following flags to
  be added to the compiler flags.

  -fb-create path/feedback

  Using Open64 with --use-feedback=path causes the following flags to be
  added to the compiler flags.

  --fb-opt path/feedback

  Linux/x86+Itanium/gcc
  -------------
    For debug builds -O is used and otherwise -O3 is used.Discovery of a
    Nocona or Core 2 Duo CPU causes a 64-bit binary to be built;
    otherwise, the binary is 32-bit. To build a 64-bit binary, -m64 is
    added to the C/C++ flags. (To build a 32-bit binary on a 64-bit CPU,
    use the --32 option as described previously.)

    When gcc 4.5 is used and the user set --with-link-time-optimizer then
    also --flto is added to compiler flags and linker flags.

  Linux/x86+Itanium/icc
  -------------
    Flags used:
    CC  = icc -static-libgcc -static-intel
    C++ = icpc -static-libgcc -static-intel
    C/C++ flags = -mp -restrict

    On Itanium we also add -no-ftz and to CC and C++ flags.

    Note that if the user of this script sets CC or CXX explicitly then
    also -static-libgcc and -static-intel needs to be set in the CC and
    CXX.

    The non-debug versions also add the following:
      C/C++ flags += -O3 unroll2 -ip

    The fast version adds (if --with-link-time-optimizer is used):
      C/C++ flags += -ipo

    On discovery of a Core 2 Duo architecture while using icc, -xT is also 
    added to the C/C++ flags; this provides optimisations specific to Core 
    2 Duo. This is added only when the --fast flag is set.

  Linux/x86/Open64
  ----------------
    For normal builds use -O3, when fast flag is set one also adds
    --march=auto to generate optimized builds for the CPU used. If
    --with-link-time-optimizer is set also -ipa is set. There is also
    a special flag --with-mso which can be set to get --mso set which
    activates optimisation for multi-core scalability.

  FreeBSD/x86/gcc
  ---------------
    No flags are used. Instead, configure determines the proper flags to 
    use.

  Solaris/x86/gcc
  ---------------
    All builds on Solaris are by default 64-bit, so -m64 is always used in
    the C/C++ flags. LDFLAGS is set to -m64 -O/-O2/-O3. If for
    some reason a 32-bit Solaris is used it is necessary to add the flag
    --32 to the script invocation. Due to bugs in compiling with -O3 on
    Solaris only -O2 is used by default, when --fast flag is used -O3 will
    be used instead.

    Sets -m64 (default) or -m32 (if specifically set) in LDFLAGS and
    C/C++ flags.

  Solaris/Sparc/Forte
  -------------------
    Uses cc as CC and CC as CXX
    Note that SunStudio uses different binaries for C and C++ compilers.

    Set -m64 (default) or -m32 (if specifically set) in ASFLAGS,
    LDFLAGS and C/C++ flags.

    Sets ASFLAGS=LDFLAGS=compiler flags=xarch=sparc, so that we compile
    Sparc v9 binaries, also -mt is set in all those since we're always
    building a multithreaded program.

    C flags   = -xstrconst    This flag is set only on SPARC
    C++ flags = -noex

    Set the following C/C++ flags:
    -fsimple=1
    -ftrap=%none
    -nofstore          This flag is set only on x86
    -xbuiltin=%all
    -xlibmil
    -xlibmopt

    Set the C++ flag:
    -noex
    -features=no%except    This flag is set only on x86

    When compiling with fast we set (-ipo only used if we have
    set --with-link-time-optimizer):
    C/C++ flags: -xtarget=native -xunroll=3 -xipo
    LDFLAGS: -xipo

    When not compiling with fast we always set -xtarget=generic

    When compiling with fast on SPARC we also set:
    C/C++ flags: -xbinopt=prepare
    LDFLAGS: -xbinopt=prepare

    When compiling with fast on x86 we also set:
    C/C++ flags: -xregs=frameptr
    When not compiling with fast we set on x86
    C/C++ flags: -xregs=no%frameptr

    On SPARC we set
    ASFLAGS = LDFLAGS = C/C++ flags = -xarch=sparc

    The optimisation level is
    -xO         Debug builds
    -xO2        Production build on SPARC
    -xO3        Production build on x86
    -xO4        Fast builds on SPARC/x86

  MacOSX/x86/gcc
  --------------
    C/C++ flags include -fno-common -arch i386.
    When 64-bits builds then i386 is replaced by x86_64.

    Non-debug versions also add -Os -felide-constructors, where "-Os"
    means the build is space-optimised as long as the space optimisations
    do not negatively affect performance. Debug versions use -O.
  
    Mac OS X builds will always be 32-bit by default, when --64 is added
    the build will be 64 bit instead. Thus the flag --m64 is added only
    when specifically given as an option.

  --with-ndb-port=PORT
    Change the default port for the MySQL Cluster management server.

  --with-ndb-port-base=PORT
    Change the default port base for MySQL Cluster data nodes.

  --without-query-cache
    Build the MySQL Server without the query cache, which is often not
    of value in MySQL Cluster applications.

  --with-atomic-ops=rwlocks|smp|up
                          Implement atomic operations using pthread
                          rwlocks or atomic CPU instructions for
                          multi-processor (default) or single-processor
                          configurations.

  --without-geometry      Do not build geometry-related portions of the
                          MySQL Server. Seldom used in MySQL Cluster
                          applications.

  --with-ndb-cc-flags=FLAGS
    This option can be used to build MySQL Cluster with error injection
    on the data nodes. It can be used to pass special options to
    programs in the NDB kernel for special test builds.
    The option for enabling data node error injection is -DERROR_INSERT.
