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

[ 83%] Built target orocos-rtt-dynamic_xenomai

Error 1
make[1]: *** [tests/CMakeFiles/parser-test.dir/all] Error 2
make: *** [all] Error 2

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 DataSource<Result>::shared_ptr t2 =
DataSource<Result>::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?
