C++ eclipse gives “Invalid Arguments” for const parameter

Question

I am using Eclipse Luna 2 CDT and having a wierd issue with indexer. The indexer fails with "const" for parameter. I am using C++11 and other c++11 functions work fine.

Sample Class

class Test {
public:
    int getX();
}

this works with no issue in eclipse

void method(Test& t) {
    t.getX();
}

This gives wierd invalid arguments exception:Invalid arguments 'Candidates are:int getX()'

void method(const Test& t) {
    t.getX(); //ERROR: Invalid arguments in eclipse
}

My question is why can Eclipse not work with const parameter. This works find with the build gcc build with no issue.

Answer 1

C ++ compiler, in order to prevent you from accidentally modifying objects, constants can not call non-const object suffix method.

we can fix like this:

int getX() const;

const object and non-const object both can call it.

why clang compiler work,maybe a clang issue(we could search later) or some optimization leads to ignore checking.

ADD:

9119 clang C++ unassignedclangbugs RESO DUPL no error calling non-const method on const object and something else.

I think this is clang issue,new version maybe fix.
