I am trying to use the ROOT special math function wigner_6j by calling “ROOT::Math::wigner_6j(5,5,4,4,4,1)” at the command line.
The error I get is as follows
[quote]Error: Function wigner_6j(5,5,4,4,4,1) is not defined in current scope (tmpfile):1:
*** Interpreter error recovered ***
If I call another function in the same library (e.g. ROOT::Math::tgamma(.5)) I get an appropriate answer.
Any suggestions for what I might be doing wrong
The version of ROOT I am using is a as follow (ROOT 5.29/03 (trunk@39055, Jun 02 2011, 09:09:23 on linuxx8664gcc). The version is about a month old but I rebuilt it to see if that was my problem.
To build ROOT I used the following configure string “./configure --with-clang --enable-roofit --enable-minuit2 --enable-gsl-shared” followed by make.
