    <p>So I made some kind of database with boost_multi_index like this:</p> <pre><code>#include &lt;boost\multi_index_container.hpp&gt; #include &lt;boost\multi_index\ordered_index.hpp&gt; #include &lt;boost\multi_index\member.hpp&gt; using namespace boost::multi_index; using namespace std; struct list_entry{ int id; string name; string* data; }; typedef multi_index_container&lt;list_entry, indexed_by&lt; ordered_unique&lt; tag&lt;int&gt;, member&lt;list_entry, int, &amp;list_entry::id&gt;&gt;, // unique id ordered_unique&lt; tag&lt;string&gt;, member&lt;list_entry, string, &amp;list_entry::name&gt;&gt;, // unique name ordered_non_unique&lt; tag&lt;string*&gt;, member&lt;list_entry, string*, &amp;list_entry::data&gt;&gt; // some data associated with the id/name &gt; &gt;table; class Database { private: table music, names; typedef table::index&lt;int&gt;::type list_id; typedef table::index&lt;string&gt;::type list_string; //some more code here }; </code></pre> <p>and it compiles fine with Visual Studio 2010.</p> <p>However I wanted to switch my project over to Code::Blocks with MinGW and it seems like he's not so happy with that, this is the compile log:</p> <pre><code>.\source\db.h|19|error: template argument 3 is invalid| .\source\db.h|15|error: template argument 2 is invalid| .\source\db.h|15|error: template argument 1 is invalid| .\source\db.h|14|error: template argument 2 is invalid| .\source\db.h|13|warning: 'typedef' was ignored in this declaration [enabled by default]| .\source\db.h|24|error: 'table' does not name a type| .\source\db.h|25|error: 'table' does not name a type| .\source\db.h|26|error: 'table' does not name a type| C:\Program Files\boost_1_54_0\boost\system\error_code.hpp|222|warning: 'boost::system::posix_category' defined but not used [-Wunused-variable]| C:\Program Files\boost_1_54_0\boost\system\error_code.hpp|223|warning: 'boost::system::errno_ecat' defined but not used [-Wunused-variable]| C:\Program Files\boost_1_54_0\boost\system\error_code.hpp|224|warning: 'boost::system::native_ecat' defined but not used [-Wunused-variable]| C:\Program Files\boost_1_54_0\boost\asio\error.hpp|244|warning: 'boost::asio::error::system_category' defined but not used [-Wunused-variable]| C:\Program Files\boost_1_54_0\boost\asio\error.hpp|246|warning: 'boost::asio::error::netdb_category' defined but not used [-Wunused-variable]| C:\Program Files\boost_1_54_0\boost\asio\error.hpp|248|warning: 'boost::asio::error::addrinfo_category' defined but not used [-Wunused-variable]| C:\Program Files\boost_1_54_0\boost\asio\error.hpp|250|warning: 'boost::asio::error::misc_category' defined but not used [-Wunused-variable]| C:\Program Files\boost_1_54_0\boost\asio\ssl\error.hpp|34|warning: 'boost::asio::error::ssl_category' defined but not used [-Wunused-variable]| C:\Program Files\boost_1_54_0\boost\asio\detail\winsock_init.hpp|116|warning: 'boost::asio::detail::winsock_init_instance' defined but not used [-Wunused-variable]| ||=== Build finished: 7 errors, 10 warnings (0 minutes, 15 seconds) ===| </code></pre> <p>I'm completely clueless since the error is not any more specific than that and I couldn't find any related problem.</p> <p>So I hope someone can give me an answer here, if more information is required I will edit it in afterwards.</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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
