error: 'template' (as a disambiguator) is only allowed within templates

I'm trying to compile some old code (robocup soccer simulation server circa 2003) with a current c compiler:

gcc-c++-4.7.2-2.fc17.x86_64

The function below generates the error in the subject of this question. Any advice about how to modify the function to get rid of the error would be much appreciated.

int getInt( const std::string& param ) const
{ return rcss::conf::Builder::template get< int >( param ); }

From C++03, 14.2.4

When the name of a member template specialization appears after . or -> in a postfix-expression, or after nested-name-specifier in a qualified-id, and the postfix-expression or qualified-id explicitly depends on a template-parameter (14.6.2), the member template name must be prefixed by the keyword template.

In your example, rcss::conf::Builder does not depend explicitly on a template-parameter, which makes the template keyword useless (VC allows it).

I am assuming that Builder is a class and get is a static template method of that class.

The keyword template is telling the compiler that get is a template method. However, gcc is saying that you shouldn't use that keyword if it's not already within a template.

So, removing the template keyword should make it work.
