Is your component in main.wxs or in some other file. If it is in main.wxs, is it above or below your definition?
<?define?> in wxs works like #define in cpp: you have to define it before you use it, and the definition exists for the file it is in (unless included in other files). That is why .wxi files exist (see the help for <?include?>). -----Original Message----- From: jo...@msli.com [mailto:jo...@msli.com] Sent: Friday, July 24, 2009 12:19 PM To: General discussion for Windows Installer XML toolset. Subject: Re: [WiX-users] correctly define preprocessor var in wxs? In my main wxs, I have <?define MyVar="foo.exe" ?> <?ifndef MyVar ?> <?error MyVar must be defined ?> <?endif?> which does cause candle to fail if I comment out the define. And in a Component, I have Target="[INSTALLDIR]$(var.MyVar)" If I run candle with out: -dMyVar="foo.exe" I get the error: Undefined preprocessor variable '$(var.MyVar)'. If I run candle with: -dMyVar="foo.exe" Candle succeeds. What is my malfunction?
