Re: [WiX-users] preprocessor variable $(var.Build)

Oliver,

I'm still a bit unsure about where you are getting the error (I.e. are you building the installation from the command line? Within Visual Studio 2005? Somewhere else?). Unfortunately, I also don't use Votive so the vast majority of this reply is guesswork!

I suspect that the MSBuild variable "Configuration" is being set, but that when you are seeing the error it is because this variable is never being passed to WiX.

Depending on your build process, to get the information to WiX you may need to pass it via the command line (e.g. -dWixVariableName=$(MSBuildVariableName) ), in which case you would access it using $(var.WixVariableName), or set an environment variable (e.g. set SomeEnvironmentVariable=$(MSBuildVariableName) ) and access it in WiX using $(env.SomeEnvironmentVariable).

It is likely that Votive is intended to do this for you (like I said, I don't use Votive, so I don't know for certain), in which case you may have uncovered a bug.

I also notice that you mention that you found a batch file setting "var.Build" to "$(ConfigurationName)". If true, this may not be desirable, since within WiX you may then need to reference that variable as $(var.var.Build). Within it's scripts, WiX requires the addition of the var prefix to indicate that you want to use a WiX variable (not an environment variable or system setting), but you do not specify that prefix when defining the variable.

Hopefully this offers at least some additional information which may help you determine where you need to look.

Regards,

Richard

Well, seems like $(Configuration) is set by Votive, but inside the WiX-code I can not access it?

With : <Property Id='MyProp' Value=$(Configuration)/>

I get the Errormessage:

Error 1 Ill-formed preprocessor variable 'Configuration'. Variables must have a prefix (like 'var.', 'env.', or 'sys.') and a name at least 1 character long. Z:\Projects\Aldi - Intranet\EwsSetup\Features\Ews_Mmc.wxs 5 1 EwsSetup

Those three throw "Undefined preprocessor variable":

On the properties of the .wixproj in the linker tab, there I can set userdefined variables, there I added "Configuration=$Configuration" but even then, I can not access this variable like above inside my WiX-code.

The variable $(Configuration) is set by most MSBuild scripts automatically (C#, VB, VJ#, WiX, etc.). Also, $(ConfigurationName) is usually set as well, but I’d probably go with $(Configuration). You won’t be able to know what the configuration is outside of MSBuild, but assuming that you’re using C# or VB.NET, then you should already have this defined for you by the time you call your Pre-build event.

If you’re using Votive (and therefore wix.targets), then you also get $(Configuration) defined for you. I’m not sure if $(ConfigurationName) is defined. If not, it’s a bug.

Alright, just found out, where this variable was set. It is set on the commandline while calling the batch-file to start the compilation of the setup.

The batch-file is called as "Pre-build event command line" in VS2005. The variable "var.Build" is set to the value of "$(ConfigurationName)". The last is homemade of VisualStudio. How can I access this "ConfigurationName" under WiX-V3?

WiX doesn't support that as it's a Visual Studio-specific concept. Votive might, though. JRock?
