[Bioc-devel] GSL on Windows

[Dong Li]

Thanks for all replies. Now it works.

I did not choose RcppGSL package because transforming arrays into
RcppGSL objects
would cause additional overhead. Although it is much easier to use
packages. I compared both under Linux and pure C runs faster.

On Windows I found the useful resources for GSL Windows DLL and headers for
both 32 and 64-bit.

As Dan pointed out, build two directories:

C
:\GSL\i386
C:\GSL\x64

and set the
​
environment variable `LIB_GSL` as  `
C
:/GSL` instead of `
C
:\GSL`. And add C:\GSL\x64\bin to the Path in case missing the DLLs.


Best regards,

Dong
