Currently, Linux, FreeBSD, Solaris + 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 SPARC for Solaris using the Forte compiler. + 3) Invokes the GCC compiler. + 4) Builds a set of MySQL Cluster Carrier Grade Edition binaries; for + more information about these, see --extended-help. + + 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 Cluster Carrier Grade Edition 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 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 make sure that a 64-bit version is built then you + should add the flag --64.

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, EXAMPLE, 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, EXAMPLE, 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, EXAMPLE, 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. + + 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. + + --with-debug[=full] + This option will ensure that the version is built with debug + information enabled; the optimisation level is decreased to -O. + + --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 + (cannot be overridden). + + --with-pic: Build all binaries using position independent assembler + to avoid problems with dynamic linkers (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: + + --with-fast-mutexes + Include an alternative implementation of mutexes that is faster on + Linux 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. + + Compiler options: + ----------------- + + This section describes the compiler options for each of the different + platforms supported by thisscript. + + The --fast option adds -mtune=cpu_arg to the C/C++ flags (provides + support for Nocona, K8, and other processors). + + Use of the --debug option adds -g to the C/C++ flags. + + FreeBSD/x86/gcc + --------------- + No flags are used. Instead, configure determines the proper flags to + use. + + Linux/x86+Itanium/gcc + ------------- + No flags are used. Instead the configure script determines the + proper flags to use for both normal and debug builds. 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.) + + Linux/x86+Itanium/icc + ------------- + Flags used: + CC = icc -static-libgcc -static-libcxa -i-static + C++ = icpc -static-libgcc -static-libcxa -i-static + C/C++ flags = -mp -restrict + + On Itanium we also add -no-ftz and -no-prefetch to CC and C++ flags. + + The non-debug versions also add the following: + C/C++ flags += -O3 unroll2 -ip + + The fast version adds: + 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. + + Solaris/x86/gcc + --------------- + All builds on Solaris are 64-bit, so -m64 is always used in the + C/C++ flags. LDFLAGS is set to -m64 -static-libgcc -O/-O2. + + Solaris/Sparc/Forte + ------------------- + Uses cc-5.0 as CC + Sets ASFLAGS=LDFLAGS=xarch=v9, so that we compile Sparc v9 binaries + C flags = -Xa -strconst -xc99=none + C++ flags = -noex + C/C++ flags = -mt -D_FORTEC -xarch=v9 + + For non-debug builds, the following flags are also used: + + C/C++ flags = -xO3 + + MacOSX/x86/gcc + -------------- + C/C++ flags include -fno-common -arch i386. + + 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.
