[Trilinos-Users] Unusual Problem with Linking

[jatin ralhan]

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?

AA.
