I have the following simplified scenario:
template< typename T>
struct A
{
A() : action_( [&]( const T& t) { })
{}
private:
boost::function< void( const T& )> action_;
};
When compiling with Visual C++ 2010, it gives me a syntax error at construction of action_:
1>test.cpp(16): error C2059: syntax error : ')'
1> test.cpp(23) : see reference to class template instantiation A<T>' being compiled
What is strange is that the same example, with no template parameter, compiles just fine:
struct A
{
A() : action_( [&]( const int& t) { })
{}
private:
boost::function< void( const int& )> action_;
};
I know that one workaround to the problem is to move the action_ initialization in the constructor body, instead of initialization list, like in the code below:
template< typename T>
struct A
{
A()
{
action_ = [&]( const T& t) { };
}
private:
boost::function< void( const T& )> action_;
};
... but I want to avoid such workaround.
Did anybody encountered such situation? Is any explanation/solution to this so called syntax error?
