Hi...
I recently ran into a number of problems trying to change wix project
behavior based on environment variable settings. A number of the things that
sounded intuitive to me didn't work.
For example
<?ifdef $(env.A) ?>
<?define myVar="foo" ?>
<?else?>
<?define myVar="bar" ?>
<?endif?>
didn't work because ifdef returns false for all environment variables always
whether they are set or not.
<?if $(env.A) ?>
<?define myVar="foo" ?>
<?else?>
<?define myVar="bar" ?>
works as long as $(env.A) is defined, but if it's not, Candle generates an
exception.
Is there any way to test for environment variable existence before you try
to use it in Wix?
Thanks
Mark
