How to display compiler output or custom build steps output when building with xcode?

Question

How can I see the output from the compiler of from the custom build steps (pre-action or post-action)?

Answer 1

Per my answer here ( Is it normal for Xcode not to detect if a pre-action failed? ) this is an issue that's been discussed in the dev forums. Pre-/post-action script non-zero status doesn't seem to have an affect, nor does the output seem to make it into any logs.
