Hi, Vladimir!
I apply your solution to my code and below is fragment of rule "run" of
my generator class, those generate path's to sources:

        local headers ;
        for src in $(sources) {
            local src-dir = [ $(src).path ] ;
            local src-name = [ $(src).name ] ;
            local path-const src-path = [ path.join $(src-dir)
$(src-name) ] ;
            headers += $(src-path) ;
            ECHO "src-path: $(src-path)" ;
BUT! Here is output when I build my project with that generator
(see ECHO for debug purpose):

src-path: test/main.cpp
src-path: test/person.hpp
src-path: test/string.hpp
src-path: test/tc_clear.cpp
src-path: test/tc_ctr_copy.cpp
src-path: test/tc_ctr_def.cpp
src-path: test/tc_ctr_fill.cpp
src-path: test/tc_insert.cpp
src-path: test/tc_insert_after.cpp
src-path: test/tc_insert_child.cpp
src-path: test/tc_insert_tree.cpp
src-path: test/tc_op_assign.cpp
src-path: test/tc_push_pop.cpp
src-path: test/tc_swap.cpp
src-path: test/tree_traits.hpp
src-path: test/type_list.hpp
src-path: test/value_gen.hpp
src-path: doc/src/dirs.hpp
src-path: doc/src/groups.hpp
src-path: doc/src/mainpage.hpp
src-path: include/dotconf/tree.hpp
src-path: include/dotconf/tree_iterator.hpp

It is relative path's - but I need absolute path's.
How I can get full (absolute) path's to source files?
