For singular, it gets worse. The last time I fixed the linker problem and got past that first fail, it generated segmentation faults on a couple other source files. I managed to fix those problems by changing the compiler option to 'gcc -O2' from '-O3', and successfully built Singular. I opened a ticket at the Singular site, "#353: gcc-4.6.1 compile segmentation fault", but later got a reply from the Singular folks that "it looks like a gcc problem, please notify gcc ..." so I don't think they're working on it. I've noticed that gcc-4.6 and/or the libc files for Ubuntu 11.10 get updated frequently, so I try to rebuild after every update, but so far they haven't fixed whatever fails.
