c++ - <!> Error during startup: Cannot load library in OMNET++ project while using sqlite3 -

-

i have omnet++ project, csw, references other omnet++ projects via project->properties->project references.

the reference project cb_csw_vehicle works fine. marked project project->properties->omnet++->makemake->options->target shared library. have libcb_csw_vehicle.dll, used main project csw. simulations csw run, using cb_csw_vehicle without problems.

the reference other project cb_csw_cloud, doesn't work. made same steps it:

  1. marked "create shared library" in omnet++->makemake->options->target
  2. checked project cb_csw_cloud in properties->project references of main project

i can build main project csw. can build libcb_csw_cloud.dll. when run simulation project csw, receive error:

<!> error during startup: cannot load library '../../../cb_csw_cloud/src//libcb_csw_cloud.dll': operation completed successfully.

the difference between these 2 projects, cb_csw_cloud uses sqlite3 library. added project following steps:

  1. set project->properties->omnet++->makemake->options->link->additional libraries link (-l option): sqlite3
  2. set project->properties->c/c++general->paths , symbols->library paths: c:/sqlite

since don't receive exact information, why libcb_csw_cloud not loaded, don't know causes problem. use in same way, other project cb_csw_vehicle, works. leads me suggestion, sqlite3 library causes problem. possible? can project csw have reference other project cb_csw_cloud, uses library sqlite3? or shall add library csw?

can me run csw project?

update: solved problem adding sqlite3 library run configuration , copying source code of cb_csw_cloud , cb_csw_vehicle projects csw project. difficult in omnet++ have lot of projects.

you have add link sqlite3 library in run configuration of csw project. go run | run configurations... | main tab | more>> , in dynamic libraries write path sqlite3 library. please note path has relative working directory, , without dll suffix, without lib prefix.
if dll file of sqlite3 doesn't contain lib prefix, try rename (for example sqlite3.dll libsqlite3.dll).

i'm using pygtk python 2.7 in ubuntu 14.04, following message: runtimewarning: pyos_inputhook not available interactive use of pygtk what reason ? when trigger? trying run script or use pygtk interactively? most likely, input hook grabbed interactive loop, e.g.: >>> import tkinter >>> root = tkinter.tk() # input hook grabbed tkinter immediate result evaluation >>> import gtk # gtk tries grab hook, fails /usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:127: runtimewarning: pyos_inputhook not available interactive use of pygtk the immediate result evaluation means expression results evaluated (e.g. window displayed) before entering main loop. have in mind, warning, not error, if bothers you, can import gtk module can (or, well, reasonably early) , release input hook: import gtk gtk.set_interactive(false) import tkinter root = tkinter.tk() # no warning here
