= Creating Custom Relink Scripts for Drivers and Agents for Progress/<nop>OpenEdge =

Custom relink scripts may be needed when our standard scripts are incompatible with your database installation and/or environment. The Progress **<code>probuild</code>** utility enables you to create such custom scripts. 

# Locate the **<code>buildenv</code>** script, typically found in the <code>$DLC/probuild/eucapp</code> directory. 
# Ensure that the environment variable settings in the <code>buildenv</code> script are accurate for your system.
# Set and export 
{{{
PROLOAD&#061;$DLC/probuild
export PROLOAD
}}}
# Type the following command at your command line:
{{{
$PROLOAD/eucapp/probuild 
}}}
# At the **Install Link Script Into** prompt, enter the full path to your **{{{~/openlink/bin}}}** directory. 
# Click **Continue**.
# Select **ESQL/C Large Client Full** from the product list. 
# Click **Continue**. 
# Give your relink script an appropriate name. For example:
{{{
ldpro7
ldpro8
ldpro9
}}}
# Give the executable to be produced an <nop>OpenLink-style Database Agent name. For example:
{{{
pro73e_sv
pro83b_sv
pro91b_sv 
}}}
# Click **Continue**. 
# Do not specify any special configurable elements. 
# Click **Continue**.
# Locate the database agent object code in the {{{/lib}}} sub-directory of your <nop>OpenLink installation. Object code files are named similarly to {{{pro7_sv.o}}}, {{{pro8_sv.o}}}, and {{{pro9_sv.o}}}.  
# Enter the full path to the relevant Database Agent object code ({{{proxxx_sv.o}}}) under "Object Files.' 
# Click **Continue**. 
# Exit {{{probuild}}}. 
# Repeat the [[RelinkMulti-TierDatabaseAgents|relink process]] with your new relink script.
