[Boost-users] Compile errors using BOOST_FOREACH on Fedora Linux

22 May 2009

      I have a class defined like this:

class SomeObject
{
public:
...

virtual void Method();

...

private:
typedef boost::shared_ptr<AnotherObject> AnotherObjectPtr;

...

std::vector<AnotherObject> m_objects;

...
};

void SomeObject::Method()
{
...

BOOST_FOREACH(AnotherObjectPtr object, m_objects){
object->DoSomething();
}
}

The code compiles fine using Boost 1.39.0 on Mac OS X 10.5 (PowerPC).

However, when I compile the same code on Fedora 10 (Intel), I get 
compile errors like:

.../boost_1_39_0/boost/foreach.hpp:221: error: expected 
nested-name-specifier before ‘int’
.../boost_1_39_0/boost/foreach.hpp:221: error: two or more data types in 
declaration of ‘parameter’

.../SomeObject.cpp:110: error: no matching function for call to

.../SomeObject.cpp:110: error: no matching function for call to

.../SomeObject.cpp:110: error: no matching function for call to

‘not_(boost::foreach::is_noncopyable<std::vector<boost::shared_ptr<AnotherObject>,

These error are quite puzzling, and I'm not sure what is causing the 
problem especially since the code compiled fine on another platform, 
which suggests it might be fine.
What is needed to fix this problem so the code will compile successfully?
