thanks a lot for fixing the configure script. I have found out in the
last days that in fact this "1.6" version might have to do with the
versioning standard of GSL for windows which according to this url:


seems to follow an independent scale since it says that right now the
latest version is "1.8". so i've made the change in the devel-version of
GSVA but i'm afraid that it may not build anymore in windows. In such a
case I guess I would have to address that by updating the configure.ac
script such that if the system is unix then requires version >= 1.12 and
if it's windows then it requires version >= 1.6. I hope I don't have to
because at the moment I have no clue how I would do that.

next to this, in a recent post at BioC 


it was described an additional step that should be done to have a
successful windows installation of the GLAD package, which also requires
GSL, and which consists of duplicating the file libgsl.dll into a file
called libgsl-0.dll

i have verified in the windows xp partition of my mac, that this latter
step is absolutely necessary to have an installation of GSVA, and GLAD
too, without problems. so i wonder whether you had to do the same with
the GSL installation of your windows machines in Seattle, or you install
GSL in windows in some other way.

thanks, i've done just that and submitted the changes to devel. if i see
that the package builds and installs correctly i'll push them to

yes, you're right, thanks for clearing this up. I've also updated
accordingly the README file of the package.
