Building fails with missing GiNaC symbol

[Isuru Fernando]

Hi,

I'm trying to build sage 8.8.rc1 on conda with conda built dependencies and I'm getting the following error.

ImportError: /_h_env/lib/python2.7/site-packages/sage/symbolic/ring.so: undefined symbol: _ZN5GiNaC9containerISt6vectorEC1ERKS1_INS_2exESaIS3_EEb

Demangled, this is

GiNaC::container<std::vector>::container(std::vector<GiNaC::ex, std::allocator<GiNaC::ex> > const&, bool)

This is with pynac 0.7.25. I can send more details if required.

Has anybody seen this error before?

On k8s, I see this symbol when doing

objdump -TC local/lib/libpynac.so.13.0.2

Not sure why nm does not see any symbols here.

nm -D doesn’t show anything?

I never use nm. I didn't know that you need to pass -D. Yes, with -D I see the symbols as well.
