Hi all,

I am trying to build orocos-rtt-1.12.1 for powerpc. I received this error:

 [ 83%] Built target orocos-rtt-dynamic_xenomai

 [ 83%] Built target message

Then I edited DataSourceAdaptor.hpp: line 512 - 514 :

Original:

     typename DataSource<const Result&>::shared_ptr t2 = DataSource<const Result&>::narrow( dsb.get() );
            if ( t2 )
            return new detail::DataSourceAdaptor<const Result&, Result>( t2 );

Modified:

    typename DataSource9::shared_ptr t2 = DataSource10::narrow( dsb.get() );
            if ( t2 )
            return new detail::DataSourceAdaptor<Result, Result>( t2 );
        

Then the error dissappeared and the rtt is installed successfully.

This is definitely not a clean way to build rtt for powerpc. I am wondering if anyone has encountered this problem and what is the solution?

Greetings, Lin
