[Bioc-devel] GSVA/configure.ac problem

from what you say here about the directory structure and the LIB_GSL
environment variable i think you probably do not have the GSL
installation from http://gnuwin32.sourceforge.net/packages/gsl.htm but
from Cygwin at http://cygwin.com which does preserve the GSL versioning
scale from the unix platform.

i've observed that after the small change at the configure.ac file
(replacing the version requirement of 1.6 by 1.12) the devel version
compiles and builds in the windows machine in Seattle without problems,
so i'll push this change to the release and update the README file to
point out that under windows if the user has Cygwin, he/she needs to set
LIB_GSL to the root of the GSL installation and add the corresponding
C:/GSL/architecture/bin to the PATH, while if the user has
gnuwin32.sourceforge.net installation needs to do the above trick of
duplicating the file.


thanks!!
