Dear Pete and Dan, Thank you very much for the above instructions. I did not succeed to compile spdlib from source code, but I succeeded to install the executables from conda. As far as I understand, conda would automatically install all the dependencies that are needed by SPDlib.
However, I can not find the python binding file "spdpy.so" from anywhere. I suppose that conda would only install the compiled binaries instead of python binding. Am I right? Therefore, I hg cloned the repository and compiled the python folder. It compiles successfully, but when I import spdpy The following error message shows: ImportError: /usr/local/site-packages/spdpy.so: undefined symbol: _ZN6spdlib13SPDFileReader14readHeaderInfoENSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEPNS_7SPDFileE I wonder if you have any idea what happens? I also tried to compile spdlib source code after conda figured out all the dependancies, and I got an error message for HDF5: src/libspdio.so.3.0.0: undefined reference to `H5::H5Location::createAttribute(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, H5::DataType const&, H5::DataSpace const&, H5::PropList const&) const' src/libspdio.so.3.0.0: undefined reference to `H5::H5File::H5File(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned int, H5::FileCreatPropList const&, H5::FileAccPropList const&)' src/libspdio.so.3.0.0: undefined reference to `H5::CompType::insertMember(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned long, H5::DataType const&) const' src/libspdio.so.3.0.0: undefined reference to `H5::CommonFG::createDataSet(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, H5::DataType const&, H5::DataSpace const&, H5::DSetCreatPropList const&) const' src/libspdio.so.3.0.0: undefined reference to `H5::CommonFG::createGroup(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, unsigned long) const' src/libspdio.so.3.0.0: undefined reference to `H5::Attribute::write(H5::DataType const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) const' src/libspdio.so.3.0.0: undefined reference to `H5::CommonFG::openDataSet(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) const' collect2: error: ld returned 1 exit status CMakeFiles/spdtileimg.dir/build.make:98: recipe for target 'spdtileimg' failed make[2]: *** [spdtileimg] Error 1 CMakeFiles/Makefile2:142: recipe for target 'CMakeFiles/spdtileimg.dir/all' failed make[1]: *** [CMakeFiles/spdtileimg.dir/all] Error 2 Makefile:149: recipe for target 'all' failed make: *** [all] Error 2 It seems like that there is am version conflict with HDF5... I wonder how can I get python binding working with conda installation. Otherwise I can not use the python importers to convert other files into SPD format. BTW, I also would like to know if the point viewer is also compiled with Conda. Do I need to install that from https://sourceforge.net/projects/spdpointsviewer/ ? I appreciate again all your help.
