Hi,
when compiling orocos-rtt-1.6.0/tests/generictask_test_3.cpp with intel compiler 10 or 11, it fails:
{{{
generictask_test_3.cpp(730): error #453: protected function "RTT::DataPortBase::operator=(RTT::DataObjectInterface *) [with T=double]" (declared at line 72 of "/opt/orocos-rtt/include/rtt/DataPort.hpp") is not accessible through a "RTT::DataPort" pointer or object
dp = new DataObject("");
^

generictask_test_3.cpp(731): error #453: protected function "RTT::DataPortBase::operator=(RTT::DataObjectInterface *) [with T=double]" (declared at line 72 of "/opt/orocos-rtt/include/rtt/DataPort.hpp") is not accessible through a "RTT::DataPort" pointer or object
dp2 = new DataObject("");
}}}

which is reasonable, since DataPort defines the operator= as protected:
{{{
template
class DataPort
: public DataPortBase
{
protected:
T minitial_value;
using DataPortBase::mconn;
using DataPortBase::operator=;
}}}
and generictask_test_3.cpp uses the operator=
{{{
DataPort dp("DName");
DataPort dp2("D2Name");

...
dp = new DataObject("");
dp2 = new DataObject("");
}}}

According to http://gcc.gnu.org/ml/gcc-prs/2001-07/msg00591.html, it shouldn't be possible to change member access with a using, and maybe so it shouldn't even compile with g++, but I can't say

thanks
