[Trilinos-Users] How to compile correctly

[Alicia M Klinvex]

Hello Nelson,

I'm copying your message to the rest of the user mailing list so that someone else can help you with linking.

And don't apologize for "bothering me."  This is what we're here for! :-)

Best wishes,
Alicia

Hello Alicia Klinvex,

I can understand how the class Tpetra::CrsMatrix
works but i have some dudes about construct the row and column map
you pointed before. The main goal is construct
the mass and stiffness sparse matrix in trilinos way for then call
Anasazi.

At instance, look for example this part of my code

typedef double scalar_type;
typedef int   local_ordinal_type;
typedef long  global_ordinal_type;

typedef ArrayRCP< size_t >              RowPointersType;
typedef ArrayRCP< local_ordinal_type >  ColumnIndicesType;
typedef ArrayRCP< scalar_type >   	ValuesType;

typedef Tpetra::CrsMatrix<scalar_type> TpetraCrsMatrix;
typedef Tpetra::Operator<scalar_type> TpetraOp_type;
typedef TpetraCrsMatrix::map_type map_type;


///data for K
RCP< const map_type > rowMap;
RCP< const map_type > colMap;
RowPointersType       ArowPointer(reinterpret_cast<size_t*>(ArowPtr), 0, 
rowPointersize, true);
ColumnIndicesType     AcolumnInd(AcolIdx,  0, Anz,            true);
ValuesType  	      Avalues(Aval,        0, Anz,            true);

// Create Stiffness CrsMatrix sparse matrix.
TpetraCrsMatrix K(rowMap, colMap, ArowPointer, AcolumnInd, Avalues);

I can not figure out how to create the maps to works in serial.
Even, in the end of compilation i have this error.
There is an order in the linking Trilinos library?
There are no reference in google about it but   DSO missing from command 
line yes.

ld: eigen_amesos.o: undefined reference to symbol 
'_ZN6Tpetra11DistributorD1Ev'
/usr/local/trilinos-11.12.1/lib/libtpetra.so.11: error adding symbols: 
DSO missing from command line
make[1]: *** [../amls] Error 1
make[1]: Leaving directory `/home/nelson/Amls/src'



Thanks and sorry for bother you.

Regards

Nelson
