Re: [Quantlib-users] Trouble installing QuantLib-SWIG

[Jack G <jac...@gm...>]

Dear Luigi,

Thanks for coming back. The configure problem turned out to be dos/unix
related - I was git cloning the files onto windows and sharing the volume
within my container, which made ubuntu unhappy. When I git clone directly
into the ubuntu container, all problems with that step are resolved.

However, I'm still having trouble at the build step. I encounter this issue
at the "make -C Python" command, and also cd'ing into the Python folder and
following your instructions to build via python (here:
https://github.com/lballabio/QuantLib-SWIG/blob/master/Python/README.txt)
when I run this command "python setup.py build". In each case, I see a lot
of deprecation warnings ending with one for "FDDividendAmericanEngine"
(I've attached the full output of my most recent attempt
in swig_stack_output.txt), followed by a very long delay. At this point
nothing happens for a very long time, in one case it eventually failed due
to virtual memory running out but on other occasions it stayed at this step
for many hours:

I've tried my own docker image, and I also tried the same using a
Dockerfile borrowed from one of your repos (I built this dockerfile
https://github.com/lballabio/dockerfiles/blob/master/quantlib-swig-devenv/Dockerfile.python3,
then ran an image, installed git and cloned the QuantLib-SWIG repo's
'binder' branch, then followed the instructions).

I feel like I'm missing something but can't see what it might be.

Thanks for the help,
Jack
