Please disregard that. It was a bug in ubuntu 11 that just got fixed. That's the good news. Bad news is my program still gets killed for over use of ram and swap space. Are you really sure 1.6.0 has the improvement to simplified index in them? Tell me do we have an algorithm for taking 2 symetry trees acting on the same indexes and merging them to create one with the symetrys of both? If we had that I'm pretty sure I could write a far more efficient simplification algorithm. Quoting Stephen Montgomery-Smith <stephen@missouri.edu>:

You probably need to do

sudo ldconfig

Sorry thats a school boy error yes I'm running ubuntu 11.4, kernal 2.6.38-8-generic, gnome 2.32.1 (yes most of this isn't relevant but I'm going for completeness)

1.9GiB ram, AMD Athlon 64 X2 dual core processor

ginac 1.6.0 was installed with the standard install commands included in the install file ./configure make sudo make install make check

all tests passed

my terminal after I tried ldconfig looked like this.

peter@peter-ubuntu:~$ man ldconfig peter@peter-ubuntu:~$ ldconfig /sbin/ldconfig.real: Can't create temporary cache file /etc/ld.so.cache~: Permission denied peter@peter-ubuntu:~$ cd Documents peter@peter-ubuntu:~/Documents$ gcc main.cpp -o main -lcln -lginac peter@peter-ubuntu:~/Documents$ ./main ./main: error while loading shared libraries: libginac.so.2: cannot open shared object file: No such file or directory

For give me but prior to using this system all I did was a bit of darwin tinkering and before that MS-dos. I'm not too clear on the specifics of how linux handles it's libraries.

You didn't tell us about your system or how and where you installed the library. Buy maybe you do have to run ldconfig?
