FDFMerge is a server based, command-line driven application that merges FDF (Forms Data Format) file information into a PDF (Portable Document Format) Form file.

Memory Requirements

Minimum free memory available to run the application: 512 MBytes

Windows Installation

Windows installation is handled by the installer and does not require any special handling.

Unix Installation

Setting environmental variables (All Unix Platforms)

In this release, there are two additional environmental variables that need to be set for FDFMerge on all UNIX platforms. If you run FDFMerge from the fdfmerge script created during installation, these environmental variables will be set by the script. If you run fdfmergeapp directly, you will need to set these environmental variables to run FDFMerge. Once FDFMerge is installed, you can view the variables needed by looking at the fdfmergeapp script created by the installer.

Setting the Appligent home directory (All Unix Platforms)

The environmental variable that stores the location of the Appligent home directory is APPLIGENT_HOME. The default location for the Appligent home directory is /usr/local/appligent. The Appligent home directory contains the library files and resources needed to run FDFMerge.

It also contains license information for FDFMerge.


export APPLIGENT_HOME=/usr/local/appligent

Setting the APDFL library path (All Unix except AIX)

The APDFL library path must be added to the LD_LIBRARY_PATH variable. The APDFL library path is located in a subdirectory of the APPLIGENT_HOME directory.

The path should be set to ${APPLIGENT_HOME}/APDFLX.X.X/Libs



Setting the APDFL library path ( AIX Only )

The APDFL library path for AIX must be added to the LIBPATH variable. The APDFL library path is located in a subdirectory of the APPLIGENT_HOME directory.

The path should be set to ${APPLIGENT_HOME}/APDFLX.X.X/Libs



Registration numbers for FDFMerge

In previous versions of FDFMerge, the FDFMerge registration number was required as a command line option with the -r flag each time fdfmergeapp was run. An FDFMerge script was provided that automatically added -r and the registration number to the fdfmergeapp command line when the script was run.

In the current release, in addition to getting the registration number from the command line, FDFMerge can get the registration number from a license file in the Appligent home directory. On UNIX systems, license files are created by the installation script and stored in the ${APPLIGENT_HOME}/license directory. For Windows, the license file is created by the installer and stored in the All UsersApplication DataAppligentLicense directory. With a valid license file, the -r is no longer required on the command line. The -r option can still be used as in previous versions, and will override the value in the license file.
