In building the Wavelet Frequency Inverse test I encounter this problem:

I am not exactly sure of what this error means.

There was a change made a few days ago here:

> <https://github.com/InsightSoftwareConsortium/ITKIsotropicWavelets/commit/80fefd47f5177d29328b0106bd2ff53fa84b0396#diff-199a2912568e5aa187aa5b572a8e01ee>

This fixes the error, but must have not made it into the source when executing git pull --recurse-submodules yet.

The remote module’s commit hash in ITK has not been updated to the latest commit in the module yet. See

> <https://github.com/InsightSoftwareConsortium/ITKIsotropicWavelets/commits/master>

  
vs.  

> <https://github.com/InsightSoftwareConsortium/ITK/blob/master/Modules/Remote/IsotropicWavelets.remote.cmake>

But there is a gerrit topic that will hopefully bring those changes in:  
[http://review.source.kitware.com/#/c/23823](http://review.source.kitware.com/#/c/23823)

In the meantime, you can either use the module from outside ITK or replace the commit hash locally.

Hi @melrobin , thanks for reporting this, I should have opened a PR for ITK after that change. Here is the patch: [http://review.source.kitware.com/#/c/23849/](http://review.source.kitware.com/#/c/23849/)

Meanwhile, you can apply this patch just changing the hash in the file `Modules/Remote/IsotropicWavelets.remote.cmake` in your ITK source folder, and rebuild. Hopefully this will be merged soon.

```auto
GIT_TAG 80fefd47f5177d29328b0106bd2ff53fa84b0396

```

Let me know how it goes with the module!

@dzenanz updated the hash for some remote modules [here](http://review.source.kitware.com/#/c/23823/), so now you should be able to compile the IsotropicWavelets module. Thanks for reporting it!
