Example dynamic_simulation_full_y gives error while linking

[eshoubak]

I am installing my build in /usr/local/GridPACK

Then I copy the examples in /usr/local/GridPACK/share to my home folder.

From there I have no problem building the hello World example. I can also build the resistor grid fine.

However trying to build the dynamic full y simulation I get a ton of errors at the linking stage, too long to list here , but first few lines are:

================================================== [ 0%] Built target dsf.x.input [ 50%] Building CXX object CMakeFiles/dsf.x.dir/dsf_main.cpp.o [100%] Linking CXX executable dsf.x /usr/bin/ld: /usr/local/GridPACK/lib/libgridpack_powerflow_module.a(pf_app_module.cpp.o): in function gridpack::parser::PTI33_parser<gridpack::network::BaseNetwork<gridpack::powerflow::PFBus, gridpack::powerflow::PFBranch> >::getCase()': /root/develop/GridPACK/src/gridpack/parser/PTI33_parser.hpp:213: undefined reference togridpack::parser::CaseParser33::CaseParser33(std::map<int, int, std::less, std::allocator<std::pair<int const, int> > >, std::map<std::cxx11::basic_string<char, std::char_traits, std::allocator >, int, std::less<std::cxx11::basic_string<char, std::char_traits, std::allocator > >, std::allocator<std::pair<std::__cxx11::basic_string<char, std::char_traits, std::allocator > const, int> > >, std::map<std::pair<int, int>, int, std::less<std::pair<int, int> >, std::allocator<std::pair<std::pair<int, int> const, int> > >*)' /usr/bin/ld: /root/develop/GridPACK/src/gridpack/parser/PTI33_parser.hpp:215: undefined reference to gridpack::parser::CaseParser33::parse(gridpack::stream::InputStream&, boost::shared_ptr<gridpack::component::DataCollection>&, double&, int&)' /usr/bin/ld: /root/develop/GridPACK/src/gridpack/parser/PTI33_parser.hpp:216: undefined reference togridpack::parser::CaseParser33::~CaseParser33()' ... ... ...

All the linking error print out "~/develop/GridPACK/src/gridpack/parser/PTI33_parser.hpp" or a variation of it having to do with the parser. The weird thing is that the above directory is my build directory which I discarded after installation finished.

After I built GridPACK all CTests passed , and as I mentioned I can compile the first two examples.

However , the dynamic simulation is what I am most interested in. Hope someone can guide me to what is going on here !

I was able to compile it manually and run it now ! As follows:

`g++ -c dsf_main.cpp -I/usr/lib/x86_64-linux-gnu/openmpi/include \ -I/usr/local/ga-5.8/include \ -I/usr/local/GridPACK/include

g++ dsf_main.o \ -L/usr/local/GridPACK/lib \ -lgridpack_timer \ -lgridpack_environment \ -lgridpack_powerflow_module \ -lgridpack_dynamic_simulation_full_y_module \ -lgridpack_parallel \ -lgridpack_partition \ -lgridpack_pfmatrix_components \ -lgridpack_ymatrix_components \ -lgridpack_components \ -lgridpack_stream \ -lgridpack_block_parsers \ -lgridpack_math \ -lgridpack_configuration \ -L/usr/local/ga-5.8/lib -lga++ -lga -larmci \ -L/usr/local/boost-1.78.0/lib -lboost_mpi -lboost_serialization \ -lboost_random \ /usr/local/petsc-3.16.4/lib/libparmetis.so \ /usr/local/petsc-3.16.4/lib/libpetsc.so.3.16 \ -L/usr/lib/x86_64-linux-gnu/openmpi/lib -lmpi_cxx -lmpi \ -o dsf_main.x`

Tracking all the symbols down took some time, but it finally worked for me.

Something might be broken in CMakeLists.txt for this example. Keeping this open in case someone wants to fix the cmake process.

Will take a look

With Cmake the issue might be linking to some default Boost installation on the system rather than the 1.78.0 version the instructions specify. I kept having linking issues even with a whittled down CMakeLists :

find_library was always picking the wrong boost libraries until I discovered the "NO_DEFAULT_PATH" option which got it to link correctly. Perhaps something similar is occurring the GridPACK Cmake files.
