Hello, I'm new to GiNaC. In fact I've just installed the Debian package. But when I tried to compile the examples given in the section "A Tour of GiNaC" in the info pages it won't work. The object file is correctly made; but the linking process just returns a lot of errors. I used the command g++ $(ginac-config --libs) example.c++ ld returns many error messages (too much to send them). Basicly there two types. First many messages like example.o(.text+0x47): In function `main': : undefined reference to `GiNaC::symbol::symbol[in-charge](std::basic_string<char, std::char_traits<char>, std::allocator< char> > const&)' And for (I think) every reference in the object file. And second there also messages like: /usr/lib/libginac.so: undefined reference to `cerr' /usr/lib/libginac.so: undefined reference to `cln::compare(cln::cl_R const &, cln::cl_R const &)' (Very much of them, too). I have checked ginac-config. It seems to report the right libraries. When I tried static linking some of the messages disappeared, but only a few. Can anyone tell me, how I can get those examples run? Thank in advance, Paul PS: My systems configuration: g++ (GCC) 3.2.3 20030309 (Debian prerelease) GiNaC 1.0.11-1 (the debian packages: libginac-dev 1.0.11-1 & libginac0 1.0.11-1) CLN 1.1.5-1 (Debian: libcln2 1.1.5-1) and Debian GNU/Linux 2.4.17
