expression must have pointer-to-struct-or-union type
      float altitude = fabsf(safe_asinf(D->z))

This error is the same as #49874 and it should should be solved by a recent commit 5aa6a2ec06

Download the latest developer build and see if the error is fixed.
Let us know if it worked, so we can take further actions.

I tried a build from today (blender-2.78-1ee43c5-win64) and the original error is gone, instead i get a different one:
Failed loading render kernel, see console for errors.

Console:

@Katharsas the error is already reported in #49901. You can subscribe to that task to follow when it gets fixed.

Since the original bug was fixed, i'll close this task.

I actually made an account so I could confirm that in the Daily build

blender-2.78-5e31e07-linux-glibc219-x86_64

While the main release still has this bug present.
