Is there anything special I have to do to enable the molecule editor in kalzium? The menu item is grayed out for me.

opengl + avogadro

Thanks, Avagadro is missing. openSUSE isn't packaging it for 11.3 some reason.

Is avagadro a runtime or buildtime dependency? I installed avagadro but it didn't seem to enable the molecular model viewer.

kalzium/CMakeLists.txt has:
if (OPENBABEL2_FOUND AND Avogadro_FOUND AND EIGEN2_FOUND)
# avoid compilerwarnings about redefinitions
# todo: use check_function_exits() ?
message(STATUS "Kalzium molecular editor enabled")
if (WIN32)
add_definitions(-DHAVE_SNPRINTF -DHAVE_STRCASECMP -DHAVE_STRNCASECMP)
endif (WIN32)
add_subdirectory(compoundviewer)
else (OPENBABEL2_FOUND AND Avogadro_FOUND AND EIGEN2_FOUND)
message(STATUS "Kalzium molecular editor disabled")
endif (OPENBABEL2_FOUND AND Avogadro_FOUND AND EIGEN2_FOUND)

Looks like a build dependency to me.

I checked the build output, it is definitely a build dependency. Thanks for your help.

Old thread, but it was useful to me.

For those who cannot enable molecular editor, eigen2 is another dependency:

Code: Select all

if (OPENBABEL2_FOUND AND Avogadro_FOUND AND EIGEN2_FOUND)
  # avoid compilerwarnings about redefinitions
  # todo: use check_function_exits() ?
  message(STATUS "Kalzium molecular editor enabled")
  if (WIN32)
    add_definitions(-DHAVE_SNPRINTF -DHAVE_STRCASECMP -DHAVE_STRNCASECMP)
  endif (WIN32)
  add_subdirectory(compoundviewer)
else (OPENBABEL2_FOUND AND Avogadro_FOUND AND EIGEN2_FOUND)
  message(STATUS "Kalzium molecular editor disabled")
endif (OPENBABEL2_FOUND AND Avogadro_FOUND AND EIGEN2_FOUND)


And from the output of cmake:

Code: Select all

-----------------------------------------------------------------------------
-- The following external packages were located on your system.
-- This installation will have the extra features provided by these packages.

   * OCaml - OCaml is needed by Kalzium for the Equation Solver
   * LibFacile - libfacile is needed by Kalzium for the Equation Solver.
   * OpenBabel2 - OpenBabel is needed by Kalzium for the 3D-molecule viewer
   * Eigen2 - A generic C++ template library for dense and sparse matrices
   * Avogadro - Advanced molecular editor
   * Chemical mime data - Needed to open CML molecules from the file manager


For ubuntu and derivate users:

Code: Select all
