"MathMore does not exist", 5.22/00 on cygwin/Vista

ROOT
1

Hi all.

I am getting the following errors when I try to fit a histogram using the latest pro release (5.22/00) on my laptop [Vista Home Premium SP1 with a cygwin installation(*)]:

Error in <TWinNTSystem::DynamicPathName>: MathMore does not exist
Error loading one dimensional GSL integrator

A google search suggested that I needed to install GSL, which I did, to no avail.

I went back to older releases (5.20/00 and 5.19/02) and the problem disappeared. Digging into root/config.log, I see that MathMore is never installed (therefore, not needed?), even for the older root versions that do not give me this problem (**)

So, I am not really sure why 5.22 is so particular about a missing MathMore library, and what I need to do to make these errors go away.

Many thanks.

Hi,

this problem has been already fixed in the latest ROOT release, 5.23.04 and also in the patched branch of 5.22. A new patched release, 5.22.00.b will be soon available.

Otherwise ROOT will build automatically Mathmore, if you have a version of GSL in your system greater than 1.08.
You can easily download GSL from ftp://ftp.gnu.org/gnu/gsl/ and then compile and install using configure and then make.

Best Regards

Hmmm, ok. It sounds like I downloaded an oider GSL version (or I did something else wrong). I will have a look when I get a chance tonight.

Thanks!

Hi,

if you have not installed GSL in a non-standard place (like /opt or /usr or /usr/local), you can set also the environment variable $GSL to your GSL installation prefix before configuring ROOT.

Hi Christos,

Just a small detail: As on Windows there is no standard place like /opt or /usr or /usr/local, just specify the GSL installation location in your configure step, e.g. ./configure win32gdk --build=debug --enable-mathmore --with-gsl-incdir=$HOME/gsl/1.10/include --with-gsl-libdir=$HOME/gsl/1.10/lib
Cheers, Bertrand.
