Using Preprocessor Statements to Debug the Script

InstallShield 2020

Use the #define and #ifdef statements to create an internal debugger in the script.

To deug a script by using the preprocessor statements:

1.

Wherever you want to insert a debug statement in the script, start with the following #ifdef directive:

#ifdef DEBUG

2.

On lines that follow that directive, type the debug statements.

3.

On a separate line after the debug statements, type:

#endif

4.

For debugging purposes, compile the following compiler setting:

DDEBUG=1

Here is an example of a debugging section using an #ifdef statement:

#ifdef DEBUG

    if nResult < 0 then

        WriteLine (LogFileHandle, "PlaceBitmap failed");

    endif;

#endif

The InstallScript Debugger enables you to trace program execution and inspect variables as your installation executes.
