QuantLib 1.7 and QuantLib-Python: cannot complete the installation
Locked
 
|
Dear all,
I'm an italian student and I'm new in QuantLib and Python environment. Anyway I'm working on my final thesis and I'm using IPython in Anaconda Environment. I discovered QuantLib some days ago and I would link to install it on my Mac OSX 10.11.5 El Capitan. I intalled XCode and relative tools and MacPorts. I completed the installation of QuantLib and I'm trying to complete the installation of QuantLib(Swig)-Python. Unfortunately I always get this error message: $ python setup.py build python: can't open file 'setup.py': [Errno 2] No such file or directory $ cd QuantLib-SWIG-1.7./configure -bash: cd: QuantLib-SWIG-1.7./configure: No such file or directory I followed all explained steps but I still have some problems and I don't know how to fix it at all  Thank you all in advance and I'm sorry for my lack of experience in this kind of things..

Hello, are you using a release from https://sourceforge.net/projects/quantlib/files/, or did you check out the sources from GitHub?

Hi Luigi,
thank you for your answer. I downloaded QuantLib Swig from https://sourceforge.net/projects/quantlib/files/ selecting "other languages". thank you |

Ok. Once you extract the release, setup.py would be in the QuantLib-SWIG-1.7/Python folder, so you have to cd into that folder before running `python setup.py build`: $ cd QuantLib-SWIG-1.7/Python $ python setup.py build $ sudo python setup.py install The same goes for running ./configure instead; what you posted should be two different commands, not one: $ cd QuantLib-SWIG-1.7 $ ./configure $ make -C Python $ sudo make -C Python install Either way should build the module.

As I said I'm completely new in this sector (I've never worked in Terminale) but your help is essential.
Thank you Luigi, I'm going to try right know. Best regards, Stefania |

Ok I applied steps that you suggested. I think it works.
The I tried to import QuantLib as ql in IPython , I get this error message: ImportError: dlopen(//anaconda/lib/python2.7/site-packages/QuantLib/_QuantLib.so, 2): Symbol not found: __ZN8QuantLib10DateParser14parseFormattedERKSsS2_
Referenced from: //anaconda/lib/python2.7/site-packages/QuantLib/_QuantLib.so
Expected in: dynamic lookupI apologize to bother you, but I really would be able to solve the problem. Thank you in advance, Stefania

You'll need to find out where you installed the QuantLib C++ library, libQuantLib.so . On Linux systems, it would be in /usr/local/lib; there's a chance that the location is the same on your Mac, too. Once you have found the library, you need to add its location to the dynamic linker path DYLD_LIBRARY_PATH; see for instance <http://superuser.com/questions/282450/where-do-i-set-dyld-library-path-on-mac-os-x-and-is-it-a-good-idea>.

Unfortunately I’m only able to find a file named _QuantLib.so in anaconda/lib/python2.7/site-packages/QuantLib.
I tried to search the C++ library but spotlight does not return anything. I cannot figure it out what I did wrong. I opened opt/local/lib but there’s no libQuantLib.so file

Sorry if I bother you again.
I found a found called libQuantLib.la then the extension is different but this is the only file which refers to libQuantLib. Is it a problem?

libQuantLib.la is ok, but it's just a stub referring to the actual library file which should be in the same place. How did you build QuantLib? Luigi On Tue, May 31, 2016 at 8:31 PM <[hidden email]> wrote:
