Environment

The OME C++ libraries and programs are configured and built to use a set of search paths for different components. It should not be necessary to override these defaults. The bf command will be able to autodetect the installation directory configure paths on most platforms, and the OME C++ libraries are also able to determine the paths on most platforms so long as the library search path is configured correctly. However, the following environment variables may be used to override the defaults if this proves necessary:

Installation root

OME_FILES_HOME

The root of the installation (if applicable). Setting this will allow the installation to be used in a location other than the one configured. It will also default all the following variables unless they are explicitly overridden individually. This is not useful if an absolute installation path has been configured (e.g. if using /usr/local).

Basic paths

These may be shared with other packages if configured to do so (e.g. if using /usr/local). See GNUInstallDirs for more details. Not all of these paths are currently used, but may be used in the future.

OME_FILES_BINDIR

Programs invocable directly by an end user (on the default PATH)

OME_FILES_SBINDIR

Programs invocable directly by an end user or admin (not on the default PATH)

OME_FILES_LIBEXECDIR

Programs not typically invoked directly (called internally by the OME-Files tools and libraries as needed)

OME_FILES_SYSCONFDIR

Configuration files

OME_FILES_SHAREDSTATEDIR

Shared state

OME_FILES_LOCALSTATEDIR

Local state

OME_FILES_LIBDIR

Libraries

OME_FILES_INCLUDEDIR

C and C++ include files

OME_FILES_OLDINCLUDEDIR

C and C++ include files (system)

OME_FILES_DATAROOTDIR

OME_FILES_SYSDATADIR

Read-only architecture-independent data

OME_FILES_INFODIR

Package-specific paths

These are used by specific packages and their dependees and are not shared with other packages. They are all subdirectories under the basic paths, above.

OME_FILES_LIBEXECDIR

OME-Files program executables

OME_QTWIDGETS_ICONDIR
