    <p>I am having issue in compiling code having templated classes nested within other templated classes. The major templated class, called <code>MyClass</code> has 50 template arguments accepting a default class type called <code>null_type_nn</code> doing nothing specific.</p> <p>My template arguments start all with the '_' character like below</p> <pre><code> template&lt; class T0=null_type_0 , class T1=null_type_1 , ... , class T50=null_type_50 &gt; MyClass; typedef MyClass&lt; _MyClassB, _MyClassC &gt; _MyClass1; typedef MyClass&lt; _MyClassD, _MyClassE &gt; _MyClass2; ..... typedef MyClass&lt; _MyClass1, _MyClass2, _MyClass3 , ..._MyClass50&gt; my_type_a; </code></pre> <p>If I don't call a certain member function of the class I don't have the error below; If I just construct a message and then access/use one of its data member I have no problem.</p> <p>What I can do to sort it out or help the compiler in its job?</p> <pre><code> : Assembler messages: :8851: Error: symbol `_ZN12mine_structIL10EncodingID5015ELS0_1011E11 AsciiStringLS0_1115E23AsciiAlphaNumericStringLS0_1130ES2_LS0_1019E6S Int16LS0_1066ES2_LS0_5030E11mine_unionILm1ES_ILS0_5042ELS0_15ES1_ LS0_16404E11mine_arrayILm4ES_ILS0_20ELS0_18ES2_LS0_1078ES3_LS0_2ES3_ LS0_19E5Dec32LS0_16E6SInt32LS0_64005E12mine_null_5LS0_64006E12 mine_null_6LS0_64007E12mine_null_7LS0_64008E12mine_null_8LS0_64009E12 mine_null_9LS0_64010E13mine_null_10LS0_64011E13mine_null_11LS0_64012E13 mine_n...// continues..it is a very big error!

    1. CO"`_` followed by capital letter" kind of names are reserved by compiler. It's better not to use them. Also you need to provide the line where the error is generated.

    2. COAre you serious? 50 template arguments?! And the error you posted does not contain any relevant information. Please post the complete text.

    3. COShow the full error, it is of the kind "Error: symbol `long_mangled_symbol_name_here` now the real error message comes here. Sometimes you just have to get your hands dirty and dig into the mess of a compiler output. Don't be afraid. It is just big, but logical. Mostly.

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.
