Eclipse CDT cannot parse methods on elements in STL containers

Question

I'm using Eclipse Juno with CDT to develop my C++ project with custom makefile. I am also using C++11 features, which I got to work with Eclipse's parser following advice here on SO.

The problem is that Eclipse is unable to parse methods or fields accessed on STL container elements. E.g.:

mainapp.h

typedef struct _PlayerCalibrationData {
    [...]
    std::string getSamplesStr()
    {
            [...]
    }
} PlayerCalibrationData;

std::vector<MainApp::PlayerCalibrationData> m_calibrationData;

mainapp.cpp

m_calibrationData[0].getSamplesStr();

getSamplesStr() will be underlined and marked as an error, with the message "Method 'getSamplesStr' could not be resolved".

The compiler doesn't complain, though, regardless of whether I invoke it from Eclipse or from the command line.

Also, when I type m_calibrationData., all vector methods pop up via content assist (i.e. it's not an issue of Eclipse not finding the vector include), but as soon as I access an element via [] or at(), content assist is quiet and anything typed manually is marked as an error.

Is it normal that this doesn't work? If yes, is there a way I can turn off assist/correction for template-based containers specifically?

EDIT

I now also tried disabling c++11 support, and if I do that the problem disappears -- but then of course the c++ 11 types and syntax aren't recognized.

EDIT 2

I imported a second project, entered exactly the same settings, and for this project the parsing works. The only difference is the project layout (different location of makefiles). But even if I delete and re-import the first project, it still doesn't work.

The problem is most likely the same as this, although that's not for eclipse. I'd post a bug for cdt — BЈовић
Seems like CDT is not properly parsing the return value of operator[] for std::vector. Do you also get errors like "Invalid arguments" for statements like foo.push_back(m_calibrationData[0])? See this bug — Adam Paetznick

this worked for me:

"your project name" -> right click -> properties:

C/C++ General -> Preprocessor Include Paths, Macros etc. -> switch to the tab named "Providers":

for "Configuration" select "Release" (and afterwards "debug")
switch off all providers and just select "CDT GCC Built-in Compiler Settings"
uncheck "Share setting entries between projects (global provider)"
in the "Command to get compiler specs:" add "-std=c++11" without the quotes (may work with quotes too)
hit apply and close the options
rebuild the index

this works for me on both mashines, at home and at work win7 x64, latest official eclipse with cdt mingw-w64 gcc 4.7.2 from the mingwbuilds project on sourceforge
