Build error...

[amiltonwong]

Dear all,

I had followed the install step but came across the following build error: (It seems the linking to openni2 issue but I had built openni2 successfully before)

Could someone give me suggestions to fix it?

Best regards, Milton

One way to debug it might be to look at the link command you're running. See CMakeFiles/InfiniTAM.dir/link.txt in your build directory. That should tell you which OpenNI library (if any) you're linking against, e.g. mine looks like this:

/usr/bin/c++ -fPIC -O3 -march=native -Wall -Wextra -Wno-unused-parameter -Wno-strict-aliasing -stdlib=libstdc++ -Wl,-search_paths_first -Wl,-headerpad_max_install_names -stdlib=libstdc++ CMakeFiles/InfiniTAM.dir/InfiniTAM.cpp.o -o InfiniTAM Engine/libEngine.a Utils/libUtils.a -framework GLUT -framework Cocoa -framework AGL -framework OpenGL ITMLib/libITMLib.a Utils/libUtils.a /Developer/NVIDIA/CUDA-5.5/lib/libcudart.dylib -Wl,-rpath -Wl,/Developer/NVIDIA/CUDA-5.5/lib /Users/stuart/Downloads/OpenNI-MacOSX-x64-2.2/Redist/libOpenNI2.dylib -Wl,-rpath,/Developer/NVIDIA/CUDA-5.5/lib

What does your link command look like? Are you correctly linking against the OpenNI library? (Common issues include specifying the wrong path etc.) Is it the right one, built for the right architecture?

(Sometimes GCC linker errors can also be caused by linking libraries in the wrong order, but that shouldn't be the case here because you're just building InfiniTAM out of the box (I assume) and it's built regularly using GCC during development.)

[amiltonwong]

@sgolodetz Thanks for your reply. CMakeFiles/InfiniTAM.dir/link.txt in my build directory is as follows (my system is ubuntu 12.04(64bit)):

/usr/bin/c++ -fPIC -O3 -march=native -Wall -Wextra -Wno-unused-parameter -Wno-strict-aliasing CMakeFiles/InfiniTAM.dir/InfiniTAM.cpp.o -o InfiniTAM -rdynamic Engine/libEngine.a Utils/libUtils.a -lglut -lXmu -lXi -lGLU -lGL -lSM -lICE -lX11 -lXext ITMLib/libITMLib.a Utils/libUtils.a /usr/local/cuda-5.5/lib64/libcudart.so -lcuda -lOpenNI -Wl,-rpath,/usr/local/cuda-5.5/lib64

You're right. the option '-lOpenNI' may not be recognized by the system. The location of OpenNI2 in my system is '/root/Download/OpenNI2'. Could you tell me how I should modify the CMakeFiles/InfiniTAM.dir/link.txt file?

THX~

Best regards, Milton

[sgolodetz]

@amiltonwong You shouldn't modify the link.txt file directly - it's auto-generated by CMake, so any changes you make to it will be overwritten. However, you could try running a modified version of that link command from the command line in your build directory to investigate the problem.

In particular, see what happens when you hard-code the path to your OpenNI library in your linker command:

/usr/bin/c++ -fPIC -O3 -march=native -Wall -Wextra -Wno-unused-parameter -Wno-strict-aliasing CMakeFiles/InfiniTAM.dir/InfiniTAM.cpp.o -o InfiniTAM -rdynamic Engine/libEngine.a Utils/libUtils.a -lglut -lXmu -lXi -lGLU -lGL -lSM -lICE -lX11 -lXext ITMLib/libITMLib.a Utils/libUtils.a /usr/local/cuda-5.5/lib64/libcudart.so -lcuda /root/Download/OpenNI2/[whatever the path to the library is] -Wl,-rpath,/usr/local/cuda-5.5/lib64

If that then works, you may just be setting the path wrong in CMake. Take a look at the variable OpenNI_LIBRARY in the advanced view in ccmake (press 't' to toggle advanced mode and scroll down the bottom). If it's not /root/Download/OpenNI2/[whatever the path to the library is], set it to that. Also make sure that OpenNI_INCLUDE_DIR is correctly set. Then reconfigure, regenerate and build.

[olafkaehler]

It's best if you run cmake as follows:

cmake /path/to/InfiniTAM -DOPEN_NI_ROOT=/path/to/OpenNI2/

(I think the above error messages indicate that you have OpenNI 1 installed in /usr/lib or /usr/local/lib. The cmake systems finds a libOpenNI.so somewhere there and then tries to link to that. It should really test whether the detected OpenNI is v1 or v2.)

[sgolodetz]

Or just do what @olafkaehler said since he's around :) He knows more than I do...

[amiltonwong]

Thank you very much you all @sgolodetz @olafkaehler @sgolodetz, I practice your suggestion. And it built successfully by using command:

/usr/bin/c++ -fPIC -O3 -march=native -Wall -Wextra -Wno-unused-parameter -Wno-strict-aliasing CMakeFiles/InfiniTAM.dir/InfiniTAM.cpp.o -o InfiniTAM -rdynamic Engine/libEngine.a Utils/libUtils.a -lglut -lXmu -lXi -lGLU -lGL -lSM -lICE -lX11 -lXext ITMLib/libITMLib.a Utils/libUtils.a /usr/local/cuda-5.5/lib64/libcudart.so -lcuda /root/Downloads/OpenNI2/Bin/x64-Release/libOpenNI2.so -Wl,-rpath,/usr/local/cuda-5.5/lib64

And then I modified the OpenNI_LIBRARY option in ccmake, and then built it successfully.

@olafkaehler, you're right. My previous linking issue is due to OpenNI 1 installed in /usr/lib.

THX you all :)

[LiliMeng]

just change the CMakeLists.txt find_package(OpenNI QUIET) to find_package(OpenNI2 QUIET)
