Hi, GiNaC 1.3.0 is out and available. The changes are: - No funny announcements anymore. - The Clifford classes have been generalized to allow working with Clifford algebras generated by arbitrary symmetric tensors or matrices. Also, a lot of new functions for Clifford algebras have been added, including automorphisms and Moebius transformations. [Contribution by V. Kisil] - Added some basic symbolic and numeric integration facilities. [Contribution by C. Dams] - The multiple polylogarithm Li() now evaluates numerically for arbitrary arguments. - New functions G(a,y) and G(a,s,y) added (another notation for multiple polylogarithms). As always, this release can be downloaded from ftp://ftpthep.physik.uni-mainz.de/pub/GiNaC/ Enjoy, Jens

It looks like flex and/or bison are missing on your system. Check the output of `configure', if those utilities are *installed*, there should be lines like these: checking for flex... flex checking for yywrap in -lfl... yes checking lex output file root... lex.yy checking whether yytext is a pointer... yes checking for bison... bison -y Best regards, Alexei.

This was indeed the problem. I didn't know flex and bison where among the prerequisites for final users. Thanks a lot, Roberto -- Prof. Roberto Bagnara Computer Science Group Department of Mathematics, University of Parma, Italy http://www.cs.unipr.it/~bagnara/ mailto:bagnara@cs.unipr.it
