Before compiling, you need to adapt the following to your environment:
|
||||
|
||||
Variables in install.sh script:
|
||||
--------------------------------------------------------------------------
|
||||
Variable name Variable description
|
||||
--------------------------------------------------------------------------
|
||||
USER Database management system administrative username
|
||||
PORT Database management system port
|
||||
VERSION Database management system version (PostgreSQL only)
|
||||
|
||||
Variables in Makefile:
|
||||
--------------------------------------------------------------------------
|
||||
Variable name Variable description
|
||||
--------------------------------------------------------------------------
|
||||
LIBDIR Database management system absolute file system
|
||||
path for third party libraries (MySQL only)
|
||||
|
||||
Then you can launch './install.sh' if you want to compile the shared
|
||||
object from the source code and create the user-defined functions on the
|
||||
database management system.
|
||||
If you only want to compile the shared object, you need to call only the
|
||||
'make' command.
|
||||
|
||||
|
||||
Notes:
|
||||
|
||||
To get as small shared libraries as possible compile with GCC 4.3 on
|
||||
both 32-bit and 64-bit architecture and strip the libraries with 'strip'
|
||||
command.

Before compiling, certain enviroment variables have to be set,
|
||||
depending on the project used. For project lib_mysqludf_sys variables
|
||||
PLATFORM_SDK_DIR and MYSQL_SERVER_DIR have to be set, while for project
|
||||
lib_postgresqludf_sys variables PLATFORM_SDK_DIR and
|
||||
POSTGRESQL_SERVER_DIR.
|

Variables:

PLATFORM_SDK_DIR Directory where the Platform SDK is installed
|

MYSQL_SERVER_DIR Directory where the MySQL is installed
|

POSTGRESQL_SERVER_DIR Directory where the PostgreSQL is installed

Procedure for setting environment variables:
