    <p>There is a lot of posts about that and I have already tried to apply solutions that have worked for others, but still not for me.</p> <p>First, everything was fine with a c++ project I am working on under Linux, with Eclipse Indigo, gcc-4.7.1, cx11 activated, and Gentoo Linux. My project uses a home built static library. I made some modifications regarding some template class declarations. Then, I had some unexpected 'could not be resolved' in my library.</p> <p>What I did is to rebuild the index of the library, clean the project and rebuild it. It compiles fine like it already used to before the modifications and before the index rebuild, but the 'could not be resolved' is still here.</p> <p>OK, I try to see at least if my main project builds. There is one <strong>unresolved name</strong> from the library. So I rebuild the main project index, and here, <strong>all standard keywords become underlined with a 'could not be resolved' everywhere</strong>, and no compilation possible since it finds thousands of unresolved names.</p> <p>I tried to clean and rebuild, to add many include paths in the project properties :</p> <pre><code>-I/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.1/plugin/include -I/usr/lib64/gcc/x86_64-pc-linux-gnu/4.7.1/include/g++-v4/algorithm -I/usr/lib/gcc/x86_64-pc-linux-gnu/4.7.1/include -I/usr/include -I/usr/include/linux -I/usr/local/include </code></pre> <p>That has changed nothing. </p> <p>The 'index/Search for unresolved features' finds :</p> <blockquote> <p>algorithm, cassert, cmath, cstdlib, fstream, iostream, map, set, sstream, string, tuple, utility</p> </blockquote> <p>I tryed to add explicitely the algorithm include path. But that has changed nothing.</p> <p>At the beginning of my .cpp, I have a <code>using namespace std;</code>. If I add <code>std::</code> before for example <code>set</code>, it changes nothing.</p> <p>Autocompletion after <code>std::</code> does not propose for example <code>set</code>.</p> <p>Of course, I have tried to close/reopen Eclipse, but without more success.</p> <p>Any clue please ?</p> <p>EDIT : I have replaced my .metadata by a back-up and it seems to work again. Still, the origin of the problem remains unknown. As most .metadata files are binary ones, I cannot investigate.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
