    text
    copied! <p>Hi all, I have a compilation error I can't seem to get through. </p> <p>Here's what I do: I declare an object of class2, and I call its function "function2". This function, in turn, declares an object of class1 and calls its function "function1". Right now, this code gets a compilation error at that point ("function1" can't be properly called):</p> <p>error: expected primary-expression before ‘)’ token</p> <p>However, if I uncomment the useless "function1", then the code compiles. I find this confusing, because this is <em>not</em> the function being called, and should not affect at all.</p> <pre class="lang-c prettyprint-override"><code>#include &lt;iostream&gt; using namespace std; template&lt;int parameter1&gt; class class1 { public: template &lt; int parameter2 &gt; void function1() { cout &lt;&lt; "We do useful things here" &lt;&lt; endl; } }; template &lt; int parameter3 &gt; class class2 { public: //template &lt; char a, char b &gt; bool function1() { // cout &lt;&lt; "Useless definition (?)" &lt;&lt; endl; //} void function2() { class1 &lt; parameter3 &gt; an_instance_of_class1; an_instance_of_class1.function1 &lt; 999 &gt; (); } }; int main(int argc, char** argv) { class2 &lt; 99 &gt; an_instance_of_class2; an_instance_of_class2.function2(); } </code></pre> <p>Does anyone know what I'm missing? Thanks in advance.</p> <p>Compiler version:</p> <pre class="lang-c prettyprint-override"><code>$ g++ --version g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 </code></pre>
