This should be relative to <(DEPTH)

[Alexander Potapenko, 2013/11/19 15:28:08]

Ditto.

[Alexander Potapenko, 2013/11/19 15:28:08]

Is there any upstream build config, doc or script that contains these flags?
Can you add a link here?

[bradn, 2013/11/22 17:49:17]

So if you use all_dependent_settings here you shouldn't need to inject it all
over the place. See other comment.

+        'libraries': [
+          '-lcxx',

[bradn, 2013/11/22 17:49:17]

You shouldn't need to do this as you're building this yourself and normal
dependency propagation should add this.

+          '-lcxxabi',
+        ],
+        'include_dirs': [
+          'include',

[Alexander Potapenko, 2013/11/19 15:28:08]

Must be relative to <(DEPTH)

[bradn, 2013/11/22 17:49:17]

In a gyp file this should be ok without <(DEPTH) actually, actually.

[Alexander Potapenko, 2013/11/19 15:28:08]

Why do you need this one?

+        '-shared',

[Alexander Potapenko, 2013/11/19 15:28:08]

-shared should be implied by the target type.

+        '-lc',
+        '-lcxxabi',

[Alexander Potapenko, 2013/11/19 15:28:08]

Provided that you have libcxxabi in the dependencies, is -lcxxabi required?
