+
+### Compilation fails accessing struct field
+
+If the code compilation fails with errors such as "reference to non-static member
+function must be called" for code such as `my_sample.my_field = value` or
+`value = my_sample.my_field` this means that the rtiddsgen version you are using

+Connext version you're using, e.g.
+
+```sh
+git checkout release/7.3.0
