Linking errors with qt pcl and vtk

I am trying to compile the PCL tutorial described here and I am facing these linking errors.

Is there anything missing in the CMakeList file?

Solution

  • The PostgreSQL library you are linking to is missing openssl, you can check it with

    ldd /usr/lib/libpq.so.5

    it should report something like

    libssl.so.1.0.0 => not found

    The same with vtk, but it doesn't find a valid TIFF library.

    First, check that you have both openssl and tiff libraries installed, if linking still fails, check if versions are correct.

    Second, if all libraries are installed, check if are from the correct architecture (all 32-bit or all 64-bit).

    Third, manually force your project to load libraries flags (both from command line CMAKE_MODULE_LINKER_FLAGS / CMAKE_SHARED_LINKER_FLAGS or in the target_link_libraries directive).
