[WiX-users] Heat.exe

[David Amey]

Hi everyone!

I've been struggling with this problem for a while, if anyone can help I would really appreciate it.

Basically I'm using heat to harvest a folder, simples. However I'm using the "-var" property in the command line (to replace the "sourceDir" in the output component's source attribute), using a variable declared in the main.wxs. This replaces the "sourceDir" as expected, but when it comes to candle to compile , it flags an error as if the variable isn't populated.

Sorry if this was hard to follow or understand (incredibly frustrated!), but if you think you can help I will try and explain a bit better.

Thanks in advance!

You have to define the values for any preprocessor variables you use in
your source code. How you do that depends on how you run the compiler
(e.g., -d on the command line or DefineConstants in MSBuild) but both
are documented in WiX.chm.

Thankyou Bob,

This now works fine!

Is it possible to set the variable within the main.wxs file so that
candle picks up the value though? Sorry if this is a stupid question!

No. But you can specify the variable in the *.wixproj file. Set the DefineConstants element (or add to it). You'll need something like the following:

<DefineConstants>VariableName=Path\To\SourceDir</DefineConstants>

Please note that the debug configuration will likely have Debug defined in DefineConstants:

<DefineConstants>Debug;VariableName=Path\To\SourceDir</DefineConstants>
