Hi, I am trying to compile GT v2.26 on 32-bit image of Ubuntu 16.04. Everything works fine until somewhere in the middle of the process I get the following error, indicating the machine is out of virtual memory. I have a 4gig swap file and a 32 GB or memory so it's highly unlikely that this is not enough. I have successfully compiled GT multiple time on a 64-bit machine, so I was wondering if there are any compatibility issues with 32-bit architectures. Thanks in advance, Vaggelis Making all in inference make[4]: Entering directory '/media/sf_shared/graph-tool-2.26/src/graph/inference' CXX layers/graph_blockmodel_layers_imp.lo In file included from layers/graph_blockmodel_layers_imp.cc:25:0: layers/../blockmodel/graph_blockmodel.hh: In lambda function: layers/../blockmodel/graph_blockmodel.hh:300:29: warning: attributes at the beginning of statement are ignored [-Wattributes] [[gnu::fallthrough]]; ^ layers/../blockmodel/graph_blockmodel.hh: In member function ‘void graph_tool::BlockState<Ts>::remove_vertices(Vlist&)’: layers/../blockmodel/graph_blockmodel.hh:666:21: warning: attributes at the beginning of statement are ignored [-Wattributes] [[gnu::fallthrough]]; ^ layers/../blockmodel/graph_blockmodel.hh: In member function ‘void graph_tool::BlockState<Ts>::add_vertices(Vlist&, Blist&)’: layers/../blockmodel/graph_blockmodel.hh:759:21: warning: attributes at the beginning of statement are ignored [-Wattributes] [[gnu::fallthrough]]; ^ virtual memory exhausted: Cannot allocate memory Makefile:793: recipe for target 'layers/graph_blockmodel_layers_imp.lo' failed make[4]: *** [layers/graph_blockmodel_layers_imp.lo] Error 1 make[4]: Leaving directory '/media/sf_shared/graph-tool-2.26/src/graph/inference' Makefile:751: recipe for target 'all-recursive' failed make[3]: *** [all-recursive] Error 1 make[3]: Leaving directory '/media/sf_shared/graph-tool-2.26/src/graph' Makefile:422: recipe for target 'all-recursive' failed make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory '/media/sf_shared/graph-tool-2.26/src' Makefile:603: recipe for target 'all-recursive' failed make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory '/media/sf_shared/graph-tool-2.26' Makefile:490: recipe for target 'all' failed make: *** [all] Error 2 -- Sent from: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/
