Potential Bug

1 post

Dear Quantlib Maintainers,

I’m an analyst trying to set QuantLib with Anaconda Python up on Mac OSX El Capitan 10.11.6.

0. After some strange ac file errors compiling, and a compile with pointer errors under testing, I finally got the lastest version of QuantLib to compile with “brew”.

1. brew currently defaults to 1.7 I got brew to compile 1.8 by modifying the ruby formula.

2. The quantlib test-suite reports all tests passed

—

A. I downloaded Quantlib-SWIG 1.8 and compiled and installed it.

B. I got a strange symbol when trying to import the library in python:

ImportError: dlopen(/Users/mark/anaconda/lib/python3.5/site-packages/QuantLib/_QuantLib.cpython-35m-darwin.so, 2): Symbol not found: __ZN8QuantLib10DateParser14parseFormattedERKSsS2_

  Referenced from: /Users/mark/anaconda/lib/python3.5/site-packages/QuantLib/_QuantLib.cpython-35m-darwin.so

  Expected in: flat namespace

 in /Users/mark/anaconda/lib/python3.5/site-packages/QuantLib/_QuantLib.cpython-35m-darwin.so

C. I get a similar error in when running the tests included in the Python director of QuantLib-SWIG-1.8.

D. I read that Removed DateParser::split method
 (deprecated in version 1.6). is this related?

I’d be happy to write a detailed OSX guide for 1.8 as the instructions, but would need help solving this last issue which I now think has to do with this DateParser change.

Any hints or suggestions?

Hello,

I'm not sure about DateParser; the linker complains about a function which was not removed. It might just be a coincidence.

May you check that the location of `libQuantLib.so` (that you build and installed with brew) is in your `LD_LIBRARY_PATH` environment variable?
