Question

I’m having a problem with eclipse C++ juno. My project compiles and runs from command line but eclipse (juno) keeps saying there are thousands of errors. For example there’s a function SetRun in my code, and eclipse mentions this error: “called Invalid arguments ‘Candidates are: void SetRun(?)'”, whereas SetRun is of type static void SetRun (uint32_t run);

I have quite a lot of similar errors like that, where eclipse doesn’t seem to understand the type of the function and puts a ‘?’ instead.

I also have many errors like this: “symbol ‘*’ could not be resolved.”

I also have many includes that can’t be resolved, although they are resolved just fine by the compiler.

I think this is all part of the same issue.

I should also note that I had this working with eclipse previously, but now everytime I open eclipse it appears that way.

If I build the project from eclipse, it build successfully.

I tried updating the index but it didn’t change a thing.

What can I do to make eclipse stop telling me about these errors?

edit:

here is an example of a include that is not resolved:

#include "ns3/core-module.h"

Answer 1

You have to manually add include and symbols paths in your project preferences. Follow this instructions. You can find a lot more information about it just goggling set up include paths eclipse.

It is normal that even though you Eclipse editor cannot resolve the path, your compiler can, because they use independent settings.

EDIT: Looks like in your case you are interested in using ns-3 in Eclipse, then you should follow this instructions.
