[Trilinos-Users] Linking problems with LOCA and Anasazi

[Phipps, Eric T]

Hi Jonas,

What compiler are you using?  Usually multiple symbol definitions resulting from template instantiations are not a problem if the compiler is using "GNU" mode for template instantiation, where the symbols are declared "weak".  However, for GNU mode the symbols do need to be the same size, and it appears they aren't in the linker errors you showed:

/usr/bin/ld: Warning: size of symbol
`_ZN7Anasazi14sortRitzValuesERKSt6vectorIdSaIdEES4_PS0_INS_5ValueISt7complexIdEEESaIS8_EEPS0_IiSaIiEESE_'
changed from 396 in ./libtrilinos_thcm.a(SolverFactory.o) to 452 in
/home/djansen/jonas/Trilinos/8.0.5/lib/libloca.a(libloca_a-LOCA_Eigensolver_AnasaziStrategy.o)

This is probably resulting from out-of-date definitions in libtrilinos_thcm.a (which I presume is a library you have created?), possibly after updating Trilinos.  Try wiping out the library and object files, and recompiling the source code for that library and see if your linker errors go away.

Hi all,

I encounter a problem when trying to use loca and anasazi independently
in the same program. More specifically, the loca headers are included in
the .C file with the main() routine. In another .C file, which I want to
link to later, I recently added the line

#include "AnasaziBlockKrylovSchurSolMgr.hpp"

whereupon the linker produced the error at the end of this message.
It looks like some templates are instantiated twice, what can I do to
avoid this?
Thanks,
Jonas
