Installation
To build the ibm_db2 extension, the DB2 application development header files and libraries must be installed on your system. DB2 does not install these by default, so you may have to return to your DB2 installer and add this option.
If you add the DB2 application development header files and libraries to a Linux or Unix operating system on which DB2 was already installed, you must issue the command db2iupdt -e to update the symbolic links to the header files and libraries in your DB2 instances.
ibm_db2 is a PECL extension, so follow the instructions in Chapter 7 to install the ibm_db2 extension for PHP. Issue the configure command to point to the location of your DB2 header files and libraries as follows:
bash$ ./configure --with-IBM_DB2=/path/to/DB2 |
