Linking the Object Files

To link instrumented object files, you must specify the option -l pgo if invoking the

linker directly. If the linker is invoked through the C/C++ or COBOL compiler and you

have specified one of the options to create an instrumented object file, the compiler

automatically inserts the -l pgo option. EpTAL supports invoking the linker through

the compiler only on the workstation (via ETK), and not on the NonStop server;

however EpTAL on the workstation does

not

automatically insert the -l pgo option.

HP Enterprise Toolkit (ETK) Considerations

For each source file that is to generate instrumented object code at compile time, you

must add the appropriate compiler driver flags to the Additional box on the compiler's

General page. You can add the information at the project level, in which case it applies

to all source files in the project, or at the file level to select a subset of files to be

instrumented. Enter the flags exactly as you would enter them on the command line

invoking a compiler driver.

In addition, you must specify the dynamic-link library zpgodll as input at link time. Enter

pgo in the Dynamic and Static Libraries text box on the Linker Input property page. If

the box already specifies other libraries, append pgo to the list, using a semicolon (;)

as the separator.
