             Summary: [patch] bridge_softmix_binaural: Enable FFTW3 in Solaris 11.
                 Key: ASTERISK-27939
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27939
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Bridges/bridge_softmix
    Affects Versions: 15.4.1, 13.21.1
         Environment: Solaris 11.3
            Reporter: Alexander Traud
            Severity: Minor
         Attachments: solaris-binaural.patch

The library [FFTW|http://www.fftw.org/] for computing the Discrete Fourier Transform is used by the project bridge_softmix_binaural. The library includes convenience functions to (de)allocate memory:
* {{fftw_malloc(.)}}
* {{fftw_free(.)}}

Furthermore, to avoid hard to read typecast statements, those convenience functions are wrapped via even more convenience functions, like for {{double}}: {{fftw_alloc_real(.)}}. The latter is not available in Solaris 11. Therefore, the attached patch replaces that convenience function as described in the [FFTW documentation...|http://www.fftw.org/fftw3_doc/Memory-Allocation.html]
