Dear Boost group, some how I get compiler erros while trying to BOOST_INSTALL_PROPERTY. My test program is really tiny: #ifndef DOMCLUST_VERTEX_PROPERTY #define DOMCLUST_VERTEX_PROPERTY #include <boost/graph/properties.hpp> namespace boost{ enum vertex_xx_t { vertex_xx = 1111}; BOOST_INSTALL_PROPERTY(vertex,vertex_xx); } #endif And gcc 3.2 complains: VertexProperty.h:8: `vertex_vertex_xx_t' was not declared in this scope VertexProperty.h:8: template argument 1 is invalid Could anybody of you tell me why? all the best Martin -- ----------------------------------------------------------------------------- Martin Okrslar MPI for Molecular Genetics phone: ++ 49 + 30 / 8413-1166 Computational Molecular Biology Fax: ++ 49 + 30 / 8413-1152 Ihnestrasse 73 email: okrslar@molgen.mpg.de D-14195 Berlin URL: http://cmb.molgen.mpg.de -----------------------------------------------------------------------------
