Hi,
currently it's not possible for me to set project dependencies. I've 5 projects in my workspace. In the projects window, I selected my active project and right-clicked to get the popupmenu. After that I clicked "Properties" and then the button "Projects dependencies...". Here then, I clicked the checkboxes of two dependant projects. All seems to be ok.
After closing and reopening the dependencies window the checkboxes are marked as expected. I saved the project and closed Code::Blocks. After reopening Code::Blocks, the named checkboxes are no longer marked, the dependencies are gone.
