I'm trying to optionally include a file in my installer at compile/link time.
If the file is included, then the installer will copy it to the appropriate
location (thus it is not optional for the user to install it). If the file is
NOT included in the installer, then it the installer skips it, and it is not an
error.
Is there a way to conditionally include a file in the installer? My automated
build system will takes care of the logic of determining whether or not the
file should be included.
As an example, I have a single feature called "Configuration":
<Feature Id="Complete" Title="Install" Level="1">
<ComponentRef Id="Configuration" />
</Feature>
In the component description, I have a config file that is required. I've
tried to add a second file (weather.lnk) that is optional:
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ProgramFilesFolder">
<Directory Id="CompanyFolderName" Name="MyCompany" >
<Directory Id="INSTALLLOCATION" Name="MyApp">
<Component Id="Configuration"
Guid="175F0351-F122-4c64-92B6-BED06F22E195">
<File Id="MyApp.exe.config"
Source="$(var.SourceRoot)\MyApp.exe.config" >
</File>
<File Id="Weather.lnk"
Source="$(var.SourceRoot)\Weather.lnk>
</File>
</Component>
</Directory>
</Directory>
</Directory>
</Directory>
If the Weather.lnk file does not exist in the given location, the linker gives
a LGHT0083 error (file not found). I'd like to annotate this file (if
possible) as optional, or somehow put a conditional around it so if it is not
found in the given location, it is not an error and is just skipped when the
installer is compiled and linked. And then assuming the successful build of
the installer, when the installer is run, it will just skip this file.
Do I need to make a separate component or feature for this particular file?
I've looked around at the descriptions of the File, Component, Feature items
and didn't see anything that was obvious to me to make it optional. I did find
the "Vital" attribute for the File - I tried setting this to "no", but still
got the link error.
Is this possible?
I'm using Wix 3.0
Thanks,
Beth
