    <p>I have a rather embarrasing question, as this problem was no issue on a linux machine and on my Windows XP machine. But now, after having finally switched to Windows 7 64bit, I ran into the basic problem of making Eclipse find my C++ include files...</p> <p><strong>My setting:</strong><br> I am running Windows 7 64bit. I have installed cygwin to "C:\Program Files\cygwin" and Eclipse Juno 64bit to "C:\Program Files\eclipse".</p> <p><strong>My problem:</strong><br> I created a basic "Hello World" C++ Makefile project with Cygwin toolchain. Compilation works without problems, but Eclipse still complains that it cannot find the include to "iostream".</p> <p><strong>What I tried:</strong><br> In Project Properties -> C/C++ General -> Paths and Symbols -> Includes, I set the Include directory for GNU C and GNU C++ to</p> <pre><code>C:\Program Files\cygwin\lib\gcc\i686-pc-cygwin\4.5.3\include </code></pre> <p>which contains the iostream include in a subdirectory. <strong>This didn't work</strong></p> <p>Then I tried the exact directory</p> <pre><code>C:\Program Files\cygwin\lib\gcc\i686-pc-cygwin\4.5.3\include\C++ </code></pre> <p>containing iostream. This time, the include was found, but even after rebuilding the index, Eclipse still coulnd't resolve std, cout and endl. Then I tried the include directory of the 3.x version of gcc</p> <pre><code>C:\Program Files\cygwin\lib\gcc\i686-pc-cygwin\3.4.4\include\C++ </code></pre> <p>and it worked. Unfortunately, I require the 4.x version of gcc, so this is no permanent solution for me.</p> <p><strong>My Question:</strong><br> How I can I resolve this problem and make Eclipse find the gcc 4.x include directories and use them correctly?</p>

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.
