undefined symbol: deflateInit_ about seal-python HOT 12 CLOSED

add /usr/local/lib or the SEAL/native/lib to /etc/ld.so.conf and refresh it sudo ldconfig
it's your interpreter does not find the dynamic link library caused.

em, have you tried in python3.7?
I got it, it's a problem

from seal-python.

I will try it with python3.7 although I expect the result to be the same as this used to work with python3.8 before the ms-seal update to 3.4.5. I expect this may be an issue with ms-seal itself or some quirk we aren't aware of as im not too familiar with binding c++ to python so learning as I go.

How did you reproduce it? was it on an ubuntu system with more up to date packages or inside an arch docker container as above?

from seal-python.

you can try to build with the cmake, so there is a ImportError, etc
I remain the CMakeLists.txt in the src folder, change the path before use it.
I'm dealing with it now if you have any idea, please tell me.

from seal-python.

I will try this in a moment, once I have had lunch. I have no cause in mind as yet, but I will look into it too.

from seal-python.

OK, Here is a solution.
Before you compile the SEAL lib, change the SEAL/native/src/CMakeLists.txt line 101 Static_PIC to Shared. then you will get the SEAL/native/lib/libseal.so
then change the lib path in setup.py or src/CMakeLists.txt.
But do attention, the path is sensitive now.

ok will try it now and let you know if it works on my end too.

from seal-python.

Hmm not sure I have done this right as im getting

ImportError: libseal.so.3.4: cannot open shared object file: No such file or directory

So I must not have installed it properly.

To confirm the changes I need to make are:
change this to Shared from Static_PIC which Is very specific i'm sure I haven't messed that up:

but then for the next one so that it finds seal

Hmm thats interesting if I run the exact same source in the ubuntu docker it works fine again ... Hmm not sure what is going on with the differences here but I will look into it. It just seems so bizarre to be acting so differently given the exact same installation steps.

If I find out what is causing this problem between ubuntu and arch I will let you know.
Thanks for all your work thus far.

add /usr/local/lib or the SEAL/native/lib to /etc/ld.so.conf and refresh it sudo ldconfig

Ok trying that now

from seal-python.

Yep that worked, ah yes of course!
Archlinux puts its shared objects in /usr/lib wheras other distros store theirs in /usr/local/lib
And I have confirmed the tests work fine. and you solved the undefined symbol error in the process.
Thanks @Huelse
