I may just be being thick, but I can’t seem to see an equivalent of the VisualStudio ‘Rebuild’ option - ie, single-click to recompile all the source files in the Project.
At the moment, it seems that I have to do ‘Clean’ first, then ‘Build’
What am I missing? 
in my perception is does a build right after a clean…
or … it used to do that,
and it still should, according to the build settings.
No - mine is definitely not doing a build after a “Clean”
previous release did however.
I have:
Standard behaviour is to rebuild after a clean.
Maybe you have inopportunely modified an option which makes the C build not triggered after a clean.
Give a look to your project’s properties:
Properties > Builders > CDT Builder > Edit…
The “after a clean” checkbox should be checked (actually, the only one not to be checked should be “During auto builds”)
these are all checked (for the ones that i can edit)
and it still doesn’t work
And is the Build Automatically option of the Project menu still checked?
That fixed it 
Thanks,
but i don’t understand how that got disabled…
