Get it here: http://search.cpan.org/~leto/Math-GSL-0.14/ 

Changes in 0.14:

    - Chebyshev Series Approximation, with tests and docs
    - Examples and new documentation in Statistics, as well as tests (Thierry)
    - Bugfixes relating to compiling on 64bit Red Hat Linux, reported by Michael Roberge
    - Improved FFT, Deriv, Integration, Chebyshev, Combination and Roots docs
    - Documentation for Math::GSL::Test 
    - Improved introduction examples in Math::GSL
    - Improved Minimization subsystem tests, but it is not functional
    - Added examples/deriv/basic

        This shows the simple fact that d/dx(sin(x)) = cos(x)

    - Added examples/sf/erfc_check (thanks to Keith Lofstrom)

        Script which tests the erfc() special function against computing
        the integral definition with gsl_integration_qagiu()

    
        This shows a considerable performance boost using Math::GSL::Vectors
        instead of List::Util when searching for the min and max elements of
        large sets of random numbers.

    - Fixed return signature of gsl_deriv_* functions to return a flat list
    - Fixed some failing tests relating to  -Duselongdouble (Sisyphus)
    - Fix location of shared objects (Sisyphus)
    - Added raw() method to RNG objects

Math::GSL 0.13_03 - More stuff!

| | Comments (0) | TrackBacks (0)
I've just sent another dev release off to CPAN, 0.13_03 to test the recent Build changes that were necessary to get AMD64 boxen to correctly compile. It turns out that they really need the "-fPIC" flag at compilation and link time or else stuff blows up:

usr/bin/ld: BLAS_wrap.o: relocation R_X86_64_32S against `a local
 symbol' can not be used when making a shared object; recompile with -fPIC
 BLAS_wrap.o: could not read symbols: Bad value
collect2: ld returned 1 exit status
error building blib/arch/auto/Math/GSL/BLAS/BLAS.so file from
 'BLAS_wrap.o' at inc/GSLBuilder.pm line 99.


This link with go active sometime tomorrow: 


New stuff since 0.13_02:

  • AMD64 Build fixes
  • Improved FFT docs
  • Improved Math::GSL::Test docs
