Thanks for your feedback. I have actually duplicated the astar_search while renaming the module as moastar_search (the code is the same). So "make install" works fine. However when I run a simple test example I get this error: *htm@htm-ub:~/camp$ ./moastar.py Traceback (most recent call last): File "./moastar.py", line 47, in <module> heuristic=lambda v: h(v, target, pos) File "/usr/lib/python2.7/dist-packages/graph_tool/search/__init__.py", line 2069, in moastar_search libgraph_tool_search.moastar_search(g._Graph__graph, AttributeError: 'module' object has no attribute 'moastar_search'* Is something missing ? Even if installation was successful ? -- View this message in context: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/...
