Re: SLEPc demo

The demos are linked to lapack because umfpack needs to be linked to lapack.

I thought that umfpack required blas.

I haven't had any success when installing atlas3-base-dev or setting ATLAS_DIR. I only see the problem when running the SLEPc demo. From 'ldd demo' I get

  liblapack.so.3 => /usr/lib/atlas/liblapack.so.3 (0xb6821000)

Maybe I didn't understand you question properly?

Can you remind me why DOLFIN is linked to lapack? I recall a thread on this a few weeks ago.

I discussed the same issue with Anders earlier. The sse2 version does not install in /usr/lib/atlas as expected. Try setting ATLAS_DIR, or, perhaps better, install atlas3-base-dev instead og atlas3-sse2-dev

Has anyone tried running the demo that uses SLEPc (demo/la/eigensolver/cpp)? When I run it, I get

./demo: symbol lookup error: /usr/lib/atlas/sse2/liblapack.so.3: undefined symbol: ATL_dGetNB

Any ideas?
