These are all symbols from libreadline. Please find the place this library is sitting at on your system and link explicitly against it by adding either -lreadline or /path/to/readline.a to the command that starts with `g++ -g -O2...' above. If you cannot find this libaray, you may get it from <ftp://ftp.gnu.org/gnu/readline/>, compile and install it. HTH. (BTW: It's only ginsh that uses libreadline for command-line editing, completion and such. The rest of GiNaC works without it.) Regards -rbk. PS: BTW, you have probably received warnings like this one when configuring GiNaC: checking for readline/readline.h... no checking for readline in -lreadline... no PPS: Just to make sure, since you have the SPARC/EGCS-2.91.xx combination: You did add `-O2 -fno-schedule-insns' to the CXXFLAGS when you compiled CLN, didn't you? Personally, I don't know of anybody who has tried out GiNaC on such a system yet, but I don't know why it shouldn't work. Can you please drop me a note when you find out it's working? -- Richard Kreckel <Richard.Kreckel@Uni-Mainz.DE> <http://wwwthep.physik.uni-mainz.de/~kreckel/> - To UNSUBSCRIBE, email to ginac-list@ginac.de with a subject of "unsubscribe".
