How do you pass in parameters to the Inno Setup command line compiler?

Question

It was suggested in the IS newsgroup to use /D= but using the iscc.exe that came with version 5.2.3 I get an "Unknown option:" error.

Then in the script, how do you use the value of the command line parameter?

Answer 1

Looks like this thread is just what you're searching for: Link

You will need the IS preprocessor.

Answer 2

From the Inno Setup helpfile:

Inno Setup Preprocessor replaces the standard Inno Setup Command Line Compiler (ISCC.exe) by an extended version. This extended version provides extra parameters to control Inno Setup Preprocessor.

The "extra parameters" include the /d option.

Answer 3

You do, as MicSim says, need the preprocessor. It's included in the latest ISPack. Once it's installed, iscc supports /D.

You can then use the values defined like this (assuming you'd done /DVERSION_NAME=1.23):

AppVerName=MyApplication v{#VERSION_NAME}
