Singular and symmetric are known to break because of misplaced libraries in link commands.  Symmetrica can be fixed by moving a '-lm' in one Makefile.  I describe the bug to the maintainer of symmetric in the following email; he has already replied and I confirmed that we would like him to fix the problem in the downloadable Symmetrica from the website.  Hopefully the official Symmetrica will contain this fix soon and we can incorporate the latest package in upcoming the upcoming Sage release.  Here's the email:

Hi,I work on the open source Sage package, and Sage fails tobuild on the latest Ubuntu 11.10 beta with the defaultcompiler gcc-4.6.1.  The problem is that Sage uses Symmetrica, and the latestgcc-4.6.1 enforces linker semantics that requires the '-lm'flag to come _after_ the .o files.   In Symmetrica, the '-lm'flag precedes the .o files, leading to the following build error:gcc -O1 -fPIC -g -DFAST -DALLTRUE -lm test.c bar.o bi.o boe.o bruch.o classical.o de.o di.o ff.o galois.o ga.o gra.o hash.o hiccup.o io.o ko.o list.o lo.o ma.o mee.o mem.o mes.o mhe.o mhh.o mhm.o mhp.o mhs.o mmm.o mms.o mod_dg_sbd.o mo.o mpp.o mps.o mse.o msh.o msm.o mss.o muir.o na.o nb.o nc.o nu.o part.o pee.o peh.o pem.o perm.o pes.o phe.o phh.o phm.o phs.o plet.o pme.o pmh.o poly.o ppe.o pph.o ppm.o ppp.o pps.o pr.o pse.o psh.o psm.o pss.o rest.o rh.o sab.o sb.o sc.o sr.o ta.o teh.o tem.o tep.o tes.o the.o thm.o thp.o ths.o tme.o tmh.o tmp.o tms.o tpe.o tph.o tpm.o tps.o tse.o tsh.o tsm.o tsp.o vc.o zo.o zykelind.o zyk.o -o test nb.o: In function convert_radical_cyclo':/home/jlh/wrk/sage-4.7.1/spkg/build/symmetrica-2.0.p5/src/!nb.c:4087: undefined reference t cos'/home/jlh/wrk/sage-4.7.1/spkg/build/symmetrica-2.0.p5/src/nb.c:4087: undefined reference t cos'/home/jlh/wrk/sage-4.7.1/spkg/build/symmetrica-2.0.p5/src/!nb.c:4087: undefined reference t cos'/home/jlh/wrk/sage-4.7.1/spkg/build/symmetrica-2.0.p5/src/nb.c:4087: undefined reference t `cos'collect2: ld returned 1 exit statusWould it be possible for you to fix this problem, for instance by simplymoving the above '-lm' to after the 'zyk.o'?  It would allow Symmetricato be built on the current Ubuntu 11.10 and later releases, and wouldallow us to use Symmetrica in Sage on Ubuntu 11.10.Thanks,John Hoebing

This is a duplicate of #10719, see also this sage-devel thread.

By the way, this is unrelated to the compiler, it's the linker.
