Hi,
When environment variable _BuildArch is not defined. The following code fails
with "Undefined preprocessor variable '$(env._BuildArch)'".
<?ifdef $(env._BuildArch)?>
<?warning You should not see this?>
<?if $(env._BuildArch) != null and $(env._BuildArch) = "x86" ?>
<?define _X86_ = "yes"?>
<?endif?>
<?endif?>
Actually I think I should use <if $(env._BuildArch) != null> for the first
statement. But I got "Undefined preprocessor variable '$(env._BuildArch)'" for
that too.
The warning text "You should not see this" is NOT displayed, which means the
the first statement is evaluated false. Then why is the <?if?> inside that
<?ifdef> is evaluated?
How can I check if an environment variable is defined or not?
I am using Wix 3.0. Thanks for any comment or suggestion!
