Problems Starting Omgui1

Q: libopenmodeller.so.0 cant be opened

When I try to run omgui1 I get the following message:

bin/omgui1: error while loading shared libraries: libopenmodeller.so.0: cannot open shared object file: No such file or directory

A: This is because libopenmodeller is not being picked up in your system ld path. After making sure your /etc/ld.so.conf has got /usr/local/lib in it, do the following:

sudo ldconfig

Q: libomgui1.so.1 cant be opened

When I try to run omgui1 I get the following message:

bin/omgui1: error while loading shared libraries: libomgui.so.1: cannot open shared object file: No such file or directory

A: This is because you have build the binary with dynamic library linkage and it cant find some of its associated libraries. There are a few wasy to fix this:

1. Build the binary with static linkage by editing settings.pro and setting the OMG_STATIC flag to true.
2. If you want dynamic linkage set your LD_LIBRARY_PATH environment variable to include the omgui1 libs e.g.

   •        export LD_LIBRARY_PATH=${HOME}/dev/cpp/omgui1/lib
         

     You could add the above to your .bash_profile to make it available each time you log in.
3. If you want dynamic linkage and you want the library to be globally available to all users on your sytem, edit your /etc/ld.so.conf and add the path to your omgui1 libs:

   •        ${HOME}/dev/cpp/omgui1/lib
         

     Then do:

            sudo ldconfig
         

4. Install or copy the omgui1 libs into one of the standard system paths such as /usr/lib or /usr/local/lib

Questions About Runtime Behaviour of omgui1

Q: Where does omgui store applications settings used at runtime?

A: We use QSettings to manage runtime settings. Under linux these are usually stored in your home dir as:

•      ~/.config/openModeller/OpenModellerGui.conf
      

  Under Windows, these settings are stored in the registry.
