Hi, I have a problem when I try to create expressions containing harmonic polylogarithms from strings. The example program (based on section 5.15.2 of the tutorial) #include <ginac/ginac.h> int main() { GiNaC::symbol x; GiNaC::symtab table; table["x"] = x; GiNaC::parser reader(table); GiNaC::ex e = reader("H({0},x)"); std::cout << e << std::endl; } terminates with the message terminate called after throwing an instance of 'GiNaC::parse_error' what(): GiNaC: parse error at line 0, column 0: unexpected token, got: "{" [GiNaC::ex GiNaC::parser::parse_primary()(parser/parser.cpp:161)] However, using the H({0},x) in ginsh works fine. I am using GiNaC version 1.6.1 on a 32bit Linux PC running openSUSE 11.3. The program was compiled with g++ version 4.5.0. Is this a bug or is this syntax for lists no longer supported? Thanks for your help. Best regards, Jan Piclum.
