<br>Hi Baoyun,<br><br>Please find attached the fixed version of your code.<br><br>I didn't quite managed to replicate your report,...<br><br>but your troubles seems to be arising from your<br>definition of parameters in the template, and <br>
very likely from the way you are invoking the<br>function.<br><br><br>Note that the template construction that you are <br>using is quite convoluted, and error prone. <br><br>You may want to reconsider simplifying it.<br>
<br><br><br>In particular, <br>templating a function over the type of Filter types<br>is unusual.<br><br><br>Another practice that you really want to avoid is<br><br> template < class T><br> function( std::vector< T > & value )<br>
<br><br><br>You could write a much cleaner version of this<br>code if you convert EmGmm into a real C++<br>class, and provide an "Execute()" or Compute()<br>method for it.<br><br><br> Regards,<br><br><br> Luis<br>

<div>I want to add a small function into one of my template implemtation txx or cxx file. Before I add h<font face="Times New Roman">aha123(), I have no problem to build and run the project. After I add void haha123() into my txx file, I </font>had multiple defintion error at the link stage.</div>

<div>Belows are my .h file and .txx file for the template function. Can somebody teach me how to figure out this problem.</div>
