[Trilinos-Users] Unusual Problem with Linking

[James Willenbring]

Jatin,

 

Are you linking against the epetra library in addition to the galeri
library, and is the epetra library listed to the right of the galeri
library?  If so, what does your link line look like, and what arguments did
you pass to the Trilinos configure process?

 

Jim

Hi,

I have linked trilinos package libraries to my C++ project with cmake.

But when I try to include amesos package in my project, it gives an linking
error as follows,

/user/jrelan/home/trilinos-9.0.0/Linux_Serial/lib/libgaleri.a(Galeri_Utils.o
): In function `Galeri::Solve(Epetra_RowMatrix const*, Epetra_MultiVector
const*, Epetra_MultiVector const*)':

collect2: ld returned 1 exit status

why is this happening only when i use amesos, nox or galeri, but works ok
when I use epetra objects.

your kind help would be appreciated.

Regards,
Jatin

OK. But when I configure with --disable-shared then make and make
install works fine.

Trilinos 8.0, it is

Is is so also for Trilinos 9.0.

How to use -DHAVE_CONFIG_H?

regards,
AA.
