Hi there, I try to build torch-ros but get the following error: [ 4%] Building CXX object CMakeFiles/torch-ros.dir/src/std/string.cpp.o [ 8%] Building CXX object CMakeFiles/torch-ros.dir/src/std/string_vector.cpp.o [ 12%] Building CXX object CMakeFiles/torch-ros.dir/src/std/string_map.cpp.o [ 16%] Building CXX object CMakeFiles/torch-ros.dir/src/std/variable.cpp.o [ 20%] Building CXX object CMakeFiles/torch-ros.dir/src/std/variable_vector.cpp.o [ 24%] Building CXX object CMakeFiles/torch-ros.dir/src/std/variable_table.cpp.o [ 28%] Building CXX object CMakeFiles/torch-ros.dir/src/ros/init.cpp.o [ 32%] Building CXX object CMakeFiles/torch-ros.dir/src/ros/callback_queue.cpp.o [ 36%] Building CXX object CMakeFiles/torch-ros.dir/src/ros/node_handle.cpp.o [ 40%] Building CXX object CMakeFiles/torch-ros.dir/src/ros/master.cpp.o [ 44%] Building CXX object CMakeFiles/torch-ros.dir/src/ros/this_node.cpp.o [ 48%] Building CXX object CMakeFiles/torch-ros.dir/src/ros/message_buffer.cpp.o [ 52%] Building CXX object CMakeFiles/torch-ros.dir/src/ros/subscriber.cpp.o [ 56%] Building CXX object CMakeFiles/torch-ros.dir/src/ros/publisher.cpp.o In file included from /opt/ros/indigo/include/ros/serialization.h:37:0, from /opt/ros/indigo/include/ros/publisher.h:34, from /opt/ros/indigo/include/ros/node_handle.h:32, from /opt/ros/indigo/include/ros/ros.h:45, from ~/deepnet/torch-ros/src/ros/torch-ros.h:9, from ~/deepnet/torch-ros/src/ros/publisher.cpp:1: /opt/ros/indigo/include/ros/message_traits.h: In instantiation of ‘static const char* ros::message_traits::MD5Sum::value(const M&) [with M = RawMessage]’: /opt/ros/indigo/include/ros/message_traits.h:255:104: required from ‘const char* ros::message_traits::md5sum(const M&) [with M = RawMessage]’ /opt/ros/indigo/include/ros/publisher.h:112:7: required from ‘void ros::Publisher::publish(const M&) const [with M = RawMessage]’ /home/zhang/deepnet/torch-ros/src/ros/publisher.cpp:34:20: required from here /opt/ros/indigo/include/ros/message_traits.h:126:34: error: ‘const class RawMessage’ has no member named ‘getMD5Sum’ return m.getMD5Sum().c_str(); ^ /opt/ros/indigo/include/ros/message_traits.h: In instantiation of ‘static const char* ros::message_traits::DataType::value(const M&) [with M = RawMessage]’: /opt/ros/indigo/include/ros/message_traits.h:264:106: required from ‘const char* ros::message_traits::datatype(const M&) [with M = RawMessage]’ /opt/ros/indigo/include/ros/publisher.h:112:7: required from ‘void ros::Publisher::publish(const M&) const [with M = RawMessage]’ ~/deepnet/torch-ros/src/ros/publisher.cpp:34:20: required from here /opt/ros/indigo/include/ros/message_traits.h:143:36: error: ‘const class RawMessage’ has no member named ‘getDataType’ return m.getDataType().c_str(); ^ /opt/ros/indigo/include/ros/message_traits.h: In static member function ‘static const char* ros::message_traits::MD5Sum::value(const M&) [with M = RawMessage]’: /opt/ros/indigo/include/ros/message_traits.h:127:3: warning: control reaches end of non-void function [-Wreturn-type] } ^ /opt/ros/indigo/include/ros/message_traits.h: In static member function ‘static const char* ros::message_traits::DataType::value(const M&) [with M = RawMessage]’: /opt/ros/indigo/include/ros/message_traits.h:144:3: warning: control reaches end of non-void function [-Wreturn-type] } ^ make[2]: * [CMakeFiles/torch-ros.dir/src/ros/publisher.cpp.o] Error 1 make[1]: * [CMakeFiles/torch-ros.dir/all] Error 2 make: *\ [all] Error 2

I'm using ros indigo so I wonder if this is a version issue. Which version of ros is this package supported? Thanks in advance!

Ah so everything fixed after I instal md5 :)

I have the same problem, but even install md5 by $luarocks install md5, the problem still exists.

Any suggestions?

Thanks a lot!
