virStorageVolTarget has no member called backingStore, resulting in compile errors.
Thanks for the report. Here's a patch:

That will fix the compilation failure, but doesn't match the error message. I think the correct fix is:
- if (vol->target.backingStore != NULL) { + if (vol->backingStore != NULL) {
No, it should be
if (vol->backingStore.path != NULL) {
Both 'backingStore' and 'target are embedded instances of virStorageVolTarget struct, so you have to check the 'path' field of that struct for NULL
