i tried install by pip install pyq and from source code, they all show runtime error?

      File "/private/var/folders/k1/5yp6mmxd1_g2x57_qf_29f980000gn/T/pip-build-6ls07tww/pyq/setup.py", line 264, in get_python_dll
        raise RuntimeError('no python dll')
    RuntimeError: no python dll

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/k1/5yp6mmxd1_g2x57_qf_29f980000gn/T/pip-build-6ls07tww/pyq/

i see someone else have some error? but cannot find how to solve.

getting same error on Linux RedHat_6.6 (6.6-1) - 2.6.32-696.20.1.el6.x86_64 as discussed in #32 tried both q 64-bit and 32-bit using anaconda 4.4.10 (not using virtual env)

@sashkab: Are the changes of the 4.1.3 release where this issue was addressed already part of the pyq that is installed by pip?

[sashkab]

@MaxHoefl 4.1.3 is what served by pypi.org when you run pip install.

Could you please provide detailed steps you use to install PyQ? Did you use virtualenv?

[MaxHoefl]

@sashkab sure, see below:

1. install anaconda 4.4.10 (latest release)

2. create pip.conf in ~/.config/pip/ where I set

[global]
proxy=https://user:password@proxy:port

3. install q in ~/ (i have tried both licensed 64-bit and unlicensed 32-bit version for linux x86) and set QHOME=/home/user/q/.

4. pip install --upgrade pip (all fine); pip install pyq

-bash-4.1$ pip install pyq

@MaxHoefl did you attempt to use workaround from #32?

[MaxHoefl]

@sashkab Just tried workaround from #32 when using 32-bit q and 64-bit q. Both gave me Successfully installed pyq-4.1.3 that's nice but

1. when I start $ pyq with the 32-bit q installation it gives me

-bash-4.1$ pyq
Welcome to kdb+ 32bit edition
For support please see http://groups.google.com/d/forum/personal-kdbplus

2. when I start $ pyq with the 64-bit licensed q installation it gives me

-bash-4.1$ pyq
'2018.04.13T14:17:32.953 /home/hoeflm/q//l32/py.so: cannot open shared object file: No such file or directory

"q"
"py:PYSO 2:(`py;3)"

I checked, the py.so file was installed to q/l64 but it's trying to find it in l32.

[sashkab]

When starting 32-bit version of PyQ — do you use 32-bit Python? From error it seems, you have 64-bit version of Python.

[MaxHoefl]

@sashkab Yes I am using python 3.6.4 Would it be hard to make it look both in l32 and l64 when searching for py.so ?

[abalkin]

Starting with release, 4.1.4 use

conda install -c kx -c enlnt pyq

to install both kdb+ and PyQ.
