If libsvn_swig_py-1.so.0 requires symbol PyUnicode_FromFormat, it is built without Py_USING_UNICODE in pyconfig.h, for Python 2.7. On the other hand, if Python library has PyUnicodeUCS4_FromFormat, it is built with Py_UNSING_UNICODE defined and Py_UNICODE_SIZE >= 4. That is to say, that Python bindings modules are broken. >>> >>> Is there currently any workaround to this without building Subversion >> from source cod I think there are no workaround without building Python bindings from source code, except to contact with the packager of that package. >> >> Use python 3. >> >> > The bindings do not support Python 3, so that is not an option.

Even if we use Subversion 1.14 LTS, we can't use Python 3 bindings without modifying existing application programs, mainly str/bytes distinction. > > Aside from that ... unfortunately I have no help to offer on the original > problem. > Cheers, -- Yasuhito FUTATSUKI <fuat...@yf.bsdclub.org>
