Sorry for the bump, but I've done a lot more looking since I asked this and come up with nothing. Do people use external tools? Is it the case that not a single C developer using Eclipse CDT does any static analysis :p ? Or am I looking in the wrong places?

No, that's because it is not quite clear what you are doing 
|
Well, I'm writing firmware for the PIC32 using piccbuilder. The compiler is pretty much GCC 3.4, but goes by the name "pic32-gcc".
I avoid any dynamically allocated memory, so I'm not too interested in detecting memory leaks. But there are lots of little things that I know static analysis tools can pick up that aren't malloc-related mistakes

CDT got built-in static analysis in 7.0 using young Codan framework which has limited set of checkers at the moment. It is possible to do SA with an external tool but you may need to be a bit determined in order to set it up well.
|
So... where do I begin? Has anyone written up how to do it with one particular tool?

Why are you using internal builder?
|
So far I haven't had any reason not to. But, I gave it a shot, and it made no difference. I set the build command to
scan-build make -k -j4 all
...which, looking in the console, does exactly the same thing as...
No reports are generated, nothing seems to be done by scan-build whatsoever. Everything is compiled as normal.
Incidentally, I've never been able to get Eclipse to "clean" a project using the external builder. It just says
make -k -j4 all
make: Nothing to be done for `all'.
I don't understand what "run your external tool in Make Targets View" means. Does it require that I manually write a makefile first?

I just figured out why this is... that output seems to be from a subsequent automatically triggered build (of course), and I don't see the results of clean (right click on the project, select "Clean") because it's automatically cleared from the console (???).
Once I created the target in the make file view, it left it in the console, I saw this:
make: del: Command not found
make: [clean] Error 127 (ignored)
So it's trying to use "del" on Debian instead of "rm". Not sure if that's an issue with Eclipse or piccbuilder.

Which toolchain did you use creating the project? I see rm -f in any project I tried and I am on Windows.
BTW which version of eclipse you are using? You are on debian, I hope you are not using 3.2, are you?

You should disable Project->Build Automatically, that's what most of users do.

I suggest to switch to external builder. Ensure you can build and clean in context menu (right-click on the project) but it is really a separate issue.
Then you can create a new "Target" in the Make Targets View. It does not have to be related to makefile. For your case, I would uncheck "Use builder settings" and enter whatever command you want to use for static analysis ([scan-build make all] I suppose? or "clang Hello.cpp") You can use "Make target" field to organize your targets (i.e. move "all" there), it is simply appended to the build command. Uncheck "Run all project builders", you don't need that.
The advantage of running in the Make Targets View (vs. Run/Launch/External-Tool facility or plain command line) is that you get Error Parsers parse build output and create markers for jumping and visualizing the errors in UI. You may need to adjust the parsers or create a new one, but it's possible GCC Error Parser would be able to pick some as it is.
Another way is to create a different build configuration (project context menu->Build Configurations->Manage->New and replace build command with "scan-build make". Whatever suits you better.

Toolchain is piccbuilder (pic32-gcc), listed as "PIC Cross Target Application". Eclipse is 3.5.2, CDT is 6.0.2
If the "del" instead of "rm" is a problem with piccbuilder, I'll file a bug there.

Yeah, I tried that. It ran scan-build, but it didn't actually do anything. That is, the code was compiled and linked, but no reports were generated.
Maybe I can take the makefile generated by Eclipse and see whether I can do it from the command line.

Ah, that was the first thing I tried, with the same results.
It doesn't have to be clang/scan-build though. The whole point of this post was to just to get *something* to work. I'll keep tinkering with it.
