Hi, I'm trying to build Python 3.2.3 against system expat library, that lies out of the ordinary directory structure (under /opt). I also have an older version of expat library in the system. No matter what shell variables or options I pass to configure and make, pyexpat gets linked against the system expat, which results in errors during tests:
pyexpat.cpython-32dmu.so: undefined symbol: XMLSetHashSalt anyone has any idea what to pass to configure/make to link pyexpat with the other expat? You'll have to upgrade your expat. The XMLSetHashSalt is new in 2.1.0 and makes it possible to avoid an algorithmic complexity attack; Python uses it in its newest bugfix releases. See for example <http://bugs.python.org/issue14234>.
Sorry, I think I misread your request. Please ignore the reply.
