Mark,

Great! The changes you made have fixed the build on my end.

I also wanted to ask about concurrency - I've had a quick play with releasing the GIL in the extension code - this works well for allowing python to do other things while the query is running, but segfaults if I try to run two queries in separate python threads. Do you plan to support that kind of concurrency?

Thanks,

Ben

Hey Ben,

Glad to see you managed to resolve the issue, I just made some changes to the linker as well to hopefully make it more portable. MonetDBLite for Python is still very much in a "it works on my machine" state. Feel free to use it but be aware that it is not particularly stable yet. If you encounter any issues/bugs/segfaults feel free to contact me and I will try to resolve them.

Best,

Hi,

I fixed this issue by swapping 

../../sql/backends/monet5/lib_sql 

and

../../monetdb5/extras/pyapi/lib_pyapi

in tools/embeddedpy/Makefile.ag

And now have a working module, thanks!

Hi,

I'm aware the embedded "monetdblite" library isn't released yet - but it seems perfect for my use case so am very excited to try it. I've tried compiling the source from the pyapi branch but run into: 

"ImportError: /usr/local/lib/python2.7/dist-packages/monetdb5/lib/monetdb5/lib_pyapi.so: undefined symbol: batint_dec2_dbl" when I 

"import monetdblite" on Linux Mint 17 with python 2.7 or 3.4

Any chance of some build instructions for this module? Or do I just need to be patient for the release? :)

Ta,

Ben
