Checking the compiler version in a script file

[Martin Reinders]

Hi everyone,

Is it possible to ensure that a script file is processed by a minimum version of Inno Setup, such as "6.3 or better"?

It seems that there is no directive for that purpose, but perhaps I overlooked it.

Background:

I just updated to Inno Setup 6.3.1 on my computer and removed the UTF-8 byte order marker from the script file.

If the product is built by a coworker on a different computer where Inno Setup is not yet updated, the UTF-8 script file would be interpreted as ANSI and the result would be wrong.

I know, in this particular situation (upgrade from 6.2 to 6.3) the ArchitecturesAllowed will be changed in a backward incompatible way (e.g. "x64" to "x64compatible") which means that an older Inno Setup compiler fails to compile the script.

But still: checking for the compiler versions seems a useful feature to me, and I wonder if that is possible.

Best regards,
Martin

Try this:

#if Ver < EncodeVer(6, 3, 0)
#error Your version is cool but 6.3 is better!
#endif

Greetings,

Martijn

Yes, ISPP can be used to enforce that:

#if Ver < 0x06010200
  #error Requires Inno Setup v6.1.2 to compile.
#endif

Thanks, Martijn and Gavin, that is perfect.
