![]() Latest version of ND4S: N-Dimensional Arrays for Scala is 0.7.2 and it was released on. ![]() ND4S is a free, open-source extension of the Scala programming language operating on the Java Virtual Machine - though it is compatible with both Java and Clojure. ![]() Once the transform has been broken up into subtransforms of sufficiently small sizes, FFTW uses hard-coded unrolled FFTs for these small sizes that were produced (at compile time, not at run time) by code generation these routines use a variety of algorithms including Cooley-Tukey variants, Rader's algorithm, and prime-factor FFT algorithms. The former only includes the shared libraries (the minimum needed by programs that link with FFTW) and the latter. Note that this source package builds two binary packages, according to the Redhat convention: fftw and fftw-devel. The source package can be found at: fftw-2.1. I installed the following packages from source tarballs: fftw3.0.1, numeric, and python24. To decompose transforms of composite sizes into smaller transforms, it chooses among several variants of the Cooley-Tukey FFT algorithm (corresponding to different factorizations and/or different memory-access patterns), while for prime sizes it uses either Rader's or Bluestein's FFT algorithm. This is the most reliable way to install the FFTW package. It works best on arrays of sizes with small prime factors, with powers of two being optimal and large primes being worst case (but still O(n log n)). So, my next question is, how do I link the libboost_python.dylib file (located at /usr/local/Cellar/boost-python/1.61.0/lib) to the _index.It does this by supporting a variety of algorithms and choosing the one (a particular decomposition of the transform into smaller transforms) it estimates or measures to be preferable in the particular circumstances. The missing symbol was found in the libboost_python.dylib file:Ġ000000000031d08 S _ZN5boost6python6detail13current_scopeE To check that I ran nm -g on the boost-python dylibs (which were installed using brew, along with the other mentioned dependencies). usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1226.10.1)īased on this, what I think is happening is that the boost-python dynamic library was not properly linked to _index.so during compilation. If you install FFTW in a non-standard location, specify this with FFTWINCLUDEPATH and FFTWLIBPATH, which are referenced in wrappers/Makefile. ![]() Then, compile fftwpp.so in the wrappers directory of fftw++ normally this is just 'make fftwpp.so'. usr/local/opt/fftw/lib/libfftw3.3.dylib (compatibility version 8.0.0, current version 8.4.0) For compiling, the first thing that you need to do is have FFTW compiled with -with-pic. Next I checked what libraries are linked to the _index.so file using otool -L: /Users//.ENV/lib/python2.7/site-packages/STEME-1.9./stempy/_release_build/_index.so: My understanding is the the file _index.so is looking for the symbol _ZN5boost6python6detail13current_scopeE but can't find it. The application does not have information about the ports which have never been built since its inception. In /Users//.ENV/lib/python2.7/site-packages/STEME-1.9./stempy/_release_build/_index.so The application fetches data for installed files from the buildbot every time a port is built. Referenced from: /Users//.ENV/lib/python2.7/site-packages/STEME-1.9./stempy/_release_build/_index.so I am able to compile the package without any errors, but when I try to run the program with the steme -help command, I get an error: 15:07:55,571:ERROR: ImportError: dlopen(/Users//.ENV/lib/python2.7/site-packages/STEME-1.9./stempy/_release_build/_index.so, 2): Symbol not found: _ZN5boost6python6detail13current_scopeE I'm trying to build a python package that is dependent on several libraries including boost, boost-python, and fftw.
