GYP variable based on build configuration

Question

Is it possible to define a GYP variable whose value depends on the choice of build configuration?

Answer 1

Just use variable $(BUILDTYPE) or $(ConfigurationName).

Better use <(CONFIGURATION_NAME) – Isobaric

Answer 2

Looks like it's impossible according to this wiki page:

• Perform “early” or “pre” variable expansion and conditional evaluation.
• ...
• Merge target settings into configurations as appropriate.

Answer 3

I think it's possible if you mean distinctions between 'Debug' and 'Release' by the 'build configuration'. Try to add the following in your *.gyp file:

...
'configurations': {
    'Debug': {
        'variables': {
            'some_variable%' : 'debug_value',
    },
    'Release': {
        'variables': {
            'some_variable%' : 'release_value',
        },
    },
}
...
