Hello Balaji,
liblac is the library produced from deal.II.
Concerning your undefined references, could you please give us your
configuration line and more information about the Trilinos version you
are using?
Thank you,
Markus

Hi,
I am new to deal.II. I just installed it and tried the examples first
to get a feel of the software so that I may use the library in my own
code. I found several problems with it. First of all, the trilinos
library does not work with deal.II out of the box. Some extra links
are needed. For example, on linking step-1 we get the following:
/usr/bin/ld: warning: libtrilinos_stratimikosamesos.so.1, needed by
/usr/lib/libdeal_II_2d.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libtrilinos_stratimikosaztecoo.so.1, needed by
/usr/lib/libdeal_II_2d.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libtrilinos_stratimikosifpack.so.1, needed by
/usr/lib/libdeal_II_2d.so, not found (try using -rpath or -rpath-link)
... (for many other libraries in the libtrilinos package)
So I wrote a simple shell script to fix this:
$ ll /usr/lib/libtrilinos_*.so | awk '//{print "ln -s " $10 " " $8
".1"}' | sudo sh
After this I tried linking and I encounter the following error:
/usr/lib/liblac.so: undefined reference to
`Epetra_CrsMatrix::ReplaceGlobalValues(int, int, double*, int*)'
/usr/lib/libdeal_II_2d.so: undefined reference to
`Teuchos::PrintActiveRCPNodes::PrintActiveRCPNodes()'
/usr/lib/liblac.so: undefined reference to
`Epetra_CrsMatrix::ReplaceMyValues(int, int, double*, int*)'
/usr/lib/liblac.so: undefined reference to
`Epetra_CrsMatrix::SumIntoMyValues(int, int, double*, int*)'
/usr/lib/libdeal_II_2d.so: undefined reference to
`Teuchos::PrintActiveRCPNodes::~PrintActiveRCPNodes()'
/usr/lib/liblac.so: undefined reference to
`Epetra_CrsMatrix::SumIntoGlobalValues(int, int, double*, int*)'
collect2: ld returned 1 exit status
I am not sure which version of liblac deal.II needs and I also don't
know what should be the package that contains this library. Can you
help me with this please?
Thanks,
Balaji
