Hi all, Now PyPy looks for lib-python/lib_pypy starting from the (real) location of its ``libpypy-c.so``, no longer from the ``pypy`` executable. Linux distribution packagers, take note! At a minimum, the ``libpypy-c.so`` must really be inside the path containing ``lib-python`` and ``lib_pypy``. Of course, you can (and likely should) also put a symlink to it from somewhere else. It is what you had previously to do with the ``pypy`` executable. Now it must be done with ``libpypy-c.so`` instead (and you no longer have to use a symlink for the ``pypy`` executable, as long as it finds its ``libpypy-c.so``). If, instead, you edit PyPy to change the way it is installed, then please take a moment to check that *embedding* works correctly. Test case: https://bitbucket.org/cffi/cffi/raw/default/demo/embedding.py https://bitbucket.org/cffi/cffi/raw/default/demo/embedding_test.c A bientôt, Armin.
