[Trilinos-Users] [Trilinos-Help] Problem with shared installation

[James Willenbring]

Amjad,

You are pulling in two lapack libraries on the link line:

/home/amjad/softwares/petsc-2.3.3-p11/externalpackages/fblaslapack/lapack3/d
potrs.f:1:
multiple definition of `dposv_'

/home/amjad/softwares/petsc-2.3.3-p11/externalpackages/fblaslapack/linux-gnu
-openmpi/libflapack.a(dposv.o):/home/amjad/softwares/petsc-2.3.3-p11/externa
lpackages/fblaslapack/lapack2/dposv.f:1:

This is what is causing the multiple definitions.  For Trilinos 8.0, it is
necessary to use -DHAVE_CONFIG_H when building your code that will link
against Trilinos.

Jim

Subject: [Trilinos-Help] Problem with shared installation

Hi,
I faced the following error while installing trilinos-8.0.0 with
--enable-shared (becuase after this I have to install DEal.II as
shared library)
Please recommend solution.


Linking epetra as a shared library
changing directory to ../../epetra/src

Also tell me about this "Any code that links to Trilinos libraries
must define HAVE_CONFIG_H"

AA
