\section Building Building MaxScale with CMake
You can also build MaxScale with CMake which makes the build process a bit more simple.
All the same dependencies are required as with the normal MaxScale build with the addition of CMake
version 2.6 for regular builds and 2.8.12 or newer if you wish to generate packages.
CMake tries to find all the required directories and files on its own but if it can't find them or you wish to
explicitly state the locations you can pass additional options to CMake by using the -D flag. To confirm the variable
values, you can run CMake in interactive mode by using the -i flag or use a CMake GUI (for example, ccmake for command line).
It is highly recommended to make a separate build directory to build into. This keeps the source and build trees clean and
makes it easy to get rid of everything you built by simply deleting the build directory.
To build MaxScale using CMake:
cd <path to MaxScale source>
mkdir build
cd build
cmake ..
make
make install
This generates the required makefiles in the current directory, compiles and links all the programs and installs
all the required files in their right places.
If you have your headers and libraries in non-standard locations, you can define those locations at configuration time as such:
cmake -D<variable>=<value>
By default, MaxScale installs to '/usr/local/skysql/maxscale' and places init.d scripts and ldconfig files into their folders. Change the INSTALL_DIR
variable to your desired installation directory and set INSTALL_SYSTEM_FILES=N to prevent the init.d script and ldconfig file installation.
If you run into any trouble while configuring CMake, you can always remove the 'CMakeCache.txt' file to clear CMake's
internal cache. This resets all values to their defaults and can be used to fix a 'stuck' configuration of CMake. This
is also a good reason why you should always build into a separate directory, because you can safely wipe the build directory clean without the
danger of deleting important files when something goes wrong.
The default values that CMake uses can be found in the 'macros.cmake' file. If you wish to change these, edit the 'macros.cmake' file
or define the variables manually at configuration time.
All the variables that control the CMake build process:
INSTALL_DIR=<path> Installation directory
BUILD_TYPE=[None|Debug|Release] Type of the build, defaults to Release (optimized)
INSTALL_SYSTEM_FILES=[Y|N] Install startup scripts and ld configuration files
EMBEDDED_LIB=<path> Path to the embedded library location (libmysqld.a for static and libmysqld.so for dynamic)
MYSQL_DIR=<path> Path to MySQL headers
ERRMSG=<path> Path to errmsg.sys file
STATIC_EMBEDDED=[Y|N] Whether to link the static or the dynamic verson of the library
GCOV=[Y|N] Generate gcov output
OLEVEL=<0-3> Level of optimization
BUILD_TESTS=[Y|N] Build tests
DEPS_OK=[Y|N] Check dependencies, use N when you want to force a recheck of values
DEBUG_OUTPUT=[Y|N] Produce debugging output when configuring CMake
RABBITMQ_LIB=<path> Path to RabbitMQ-C libraries
RABBITMQ_HEADERS=<path> Path to RabbitMQ-C headers
MYSQL_CLIENT_LIB=<path> Path to MySQL client libraries
MYSQL_CLIENT_HEADERS=<path> Path to MySQL client headers
