i don't understand what he needs, cause i have the same system (Ubuntu 9.04) and the same installation of Ginac at work and it works. I already tried to uninstall and to install new one more time - nothing changes! Please HELP!!!
It looks like there's an old (1.4.x) GiNaC library around. The compiler generated simple_function.o using new (1.5.x) GiNaC headers, but the linker picked up the old library. Find the old one and remove it. Luck! -richy. -- Richard B. Kreckel <http://www.ginac.de/~kreckel/>
