Geopackage Export plugin isn't loading

The GeopackageExport plugin requires access to external files (DLL's on Windows and lib*.so on Linux). These should have been included in the binary package for the plugins.

On Windows the folder containing the plugin and support DLL's must be added to the PATH environment variable. Do this by either:

  • Editing/Adding the PATH environment variable for the System or User (Control Panel>System and Security>System - Advanced system settings - Environment Variables)
  • Adding a line like "@set PATH=%HOMEPATH%.od\bin\win64\Release;%PATH%" (adjust "%HOMEPATH%.od\bin\win64\Release" to reflect your installation) to the bat script used to start OpendTect

Plugins not loading

  1. Try manually loading the plugin.

  2. Check the OpendTect log file for error messages and see if there is already a solution outlined elsewhere in this page.

Per-user Installation and Multiple OpendTect versions

The OpendTect-6.4-plugins won't work in OpendTect 6.2 and the OpendTect-6.2-plugins won't work in OpendTect 6.4. Here is a way to use the plugins with mutliple versions of OpendTect.

Use the OD_USER_PLUGIN_DIR environment variable

For Windows

1.Create ODPlugins\6.4.0 and ODPlugins\6.2.0 folders in the C:\Users\%username% folder

2.Install the OpendTect-6.2-plugins in the 6.2.0 folder and the OpendTect-6.4-plugins in the 6.4.0 folder as per the Installation instructions.

3.Create a "bat" file to start each version of OpendTect that sets the OD_USER_PLUGIN_DIR environment variable to the appropriate folder before starting OpendTect. Here is what odt_6_4.bat might look like:

@set OD_USER_PLUGIN_DIR=%HOMEPATH%\ODPlugins\6.4.0
start "" "C:\Program Files\OpendTect\6.4.0\bin\win64\Release\od_start_dtect.exe"
For Linux

1.Create ODPlugins\6.4.0 and ODPlugins\6.2.0 folders in the users home directory

    mkdir ~/ODPlugins
    mkdir ~/ODPlugins/6.4.0 
    mkdir ~/ODPlugins/6.2.0

2.Install the OpendTect-6.4-plugins in the users 6.4.0 folder and the OpendTect-6.2-plugins in the 6.2.0 folder as per the Installation instructions.

3.Create executable shell scripts to start each version of OpendTect that sets the OD_USER_PLUGIN_DIR to the appropriate folder before starting OpendTect. Here is what odt_6_4.csh might look like:

    #!/bin/csh -f
    setenv OD_USER_PLUGIN_DIR "$HOME/ODPlugins/6.4.0"
    /path to OpendTect 6.4/start_dtect

libstdc++.so.6: version 'GLIBCXX_3.4.??' not found

This happens when the plugin is built with a gcc version different to the version used to build OpendTect. Solutions are:

  1. (Easy and seems to work ok but could break something) Rename the libstdc++.so.6 file in the OpendTect installation bin/lux64 folder to say old_libstdc++.so.6 and restart OpendTect.

  2. (Hard) Install the same version of gcc that OpendTect was built with and rebuild the plugin.

  3. (Hardest) Build OpendTect from source using your installed gcc.
