Code::Blocks 17.2 message : The Parser is still parsing files

[John R]

On Ubuntu 18.04.1, I've built myself a latest copy of the Deb 
files for Code::Blocks 17.12svn0, and installed all

All seems to work on a Hello World, except I get this message:-

The Parser is still parsing files. > Reasons:
- still need to mark files as local

And I've not found a solution.
Any suggestions?

Thx
