I can confirm I also get this error, both with the minimal test case you provided, and in the real code-base that I'm using/working on at the moment. This is currently preventing me from upgrading to Boost 1.40. John B Nil Geisweiller wrote:
It is weird, I tried with 2 settings
Ubuntu 9.04, gcc-4.3.3, boost 1.40 Ubuntu 9.10, gcc-4.4.1, boost 1.40
And I get the compiling errors:
/usr/include/boost/property_map/property_map.hpp: In instantiation of ‘boost::property_traits<int>’: /usr/include/boost/graph/two_bit_color_map.hpp:46: instantiated from ‘boost::two_bit_color_map<int>’ /home/a-lin/Sources/test/test.cpp:10: instantiated from here /usr/include/boost/property_map/property_map.hpp:31: error: ‘int’ is not a class, struct, or union type /usr/include/boost/property_map/property_map.hpp:32: error: ‘int’ is not a class, struct, or union type /usr/include/boost/property_map/property_map.hpp:33: error: ‘int’ is not a class, struct, or union type /usr/include/boost/property_map/property_map.hpp:34: error: ‘int’ is not a class, struct, or union type
Has anyone experienced problem too?
Thanks Nil

Hi,
it seems there is a conflict between strong_components.hpp and variant, maybe the method boost::get is wrongly overloaded.
The problem occurs with 1.40 but not with 1.37, and it is still occurs with the last svn.
I attach a minimal code to reproduce the bug + compile error
###### test.cpp ######
//uncomment the line below to get the bug #include <boost/graph/strong_components.hpp> #include <boost/variant.hpp>
typedef boost::variant < int, float > intorfloat;
int main() { int i(2); intorfloat iof(i); return boost::get<int>(iof); //problem is here }
Works for me :/ MSVC 2008, Vista, Boost 1.40.
