The following procedures produced the l64 binaries of PyQ on CentOS7. How can I get the l32 binaries? How can I get it without root? Thx. ============================ [http://code.kx.com/wiki/Contrib/PyQ](http://code.kx.com/wiki/Contrib/PyQ) login as root unzip kdb to /root/q easy\_install pip pip install -i [https://pypi.enlnt.com](https://pypi.enlnt.com) pyq ./python.q ./p.k ./l64/py.so ./l64/p.so ---

Thx. I think your suggestion should work in python 32 bit. But that would be limited by the 32 bit address space. I have just found that qPython is a native python driver that works w/o any C++ bridge. And it worked on centos7 + python 64 bit ^\_^ [http://www.devnet.de/exxeleron/qpython/](http://www.devnet.de/exxeleron/qpython/) ---

I have just found that qPython is a native python driver that works w/o any C++ bridge. PyQ and qPython solve two different problems.  qPython is a Python client for kdb+, while PyQ is Python running inside the kdb+ process. Take a look at the access times for PyQ: \<[https://pyq.enlnt.com/slides/#/4\](https://pyq.enlnt.com/slides/#/4%5C)\>.  I bet you won’t achieve that with any client-side solution.    ---

Alex: Your response to the “Sorting half of a list” is quite interesting ^\_^ IIRC I have compiled PyQ on centos6.6 32 bit, copied the binaries to centos6.6 64 bit, and ran kdb 32 bit embedded in python 64 bit. I have yet to try that on centos7 64 bit. Cross-compiling requires a bit of work. Does the embedded kdb in PyQ listen on any network port? Thx.
