|
|
- Return the full path to a shared library file installed in
|
|
- ``$SAGE_LOCAL/lib`` or the directories associated with the
|
|
- Python sysconfig.
|
|
-
|
|
- This can also be passed more than one library name (e.g. for cases where
|
|
- some library may have multiple names depending on the platform) in which
|
|
- case the first one found is returned.
|
|
-
|
|
- This supports most *NIX variants (in which ``lib<libname>.so`` is found
|
|
- under ``$SAGE_LOCAL/lib``), macOS (same, but with the ``.dylib``
|
|
- extension), and Cygwin (under ``$SAGE_LOCAL/bin/cyg<libname>.dll``,
|
|
- or ``$SAGE_LOCAL/bin/cyg<libname>-*.dll`` for versioned DLLs).
|
|
-
|
|
- For distributions like Debian that use a multiarch layout, we also try the
|
|
- multiarch lib paths (i.e. ``/usr/lib/<arch>/``).
|
|
-
|
|
- This returns ``None`` if the file does not exist.
