[petsc-users] Linking error with C++ code: undefined symbols

Tue Mar 23 19:37:00 CDT 2010

(Please let me know if I can give any additional information that would be
helpful for this problem.)

I'm trying to use Petsc in an object-oriented C++ code, developing with g++
on Mac OS X 10.5, and I'm running into some problems in the linking stage.
I've defined an object that uses Petsc (what I'm calling the GmresSolver
class), and the object compiles just fine.  However, when it comes time to
compile the driver (Laplace.cc) and link to Petsc libraries, I see a bunch
of "Undefined symbol" errors.

In my object code that uses Petsc (GmresSolver.h), I have included the Petsc
header file as:
extern "C" {
#include "petscksp.h"
}

In the driver (Laplace.cc), depending on how I include the Petsc header
file, I get different errors.  If I include it like I do in GmresSolver.h,
extern "C" {
#include "petsc.h"
}

I get a whole slew of header file syntax errors (see postscript of email).
If I just include the header file,
#include "petsc.h"

then I get the undefined symbols problem (more below).

My configure line for Petsc is
Users/charles/pkg/petsc-2.3.3-p15/config/configure.py \
   --prefix=$HOME/pkg/petsc-2.3.3-p15 \
   --with-python \
   --with-mpi=0 \
   --with-debugging=1 \
   PETSC_DIR=$HOME/pkg/petsc-2.3.3-p15

Here's my step-by-step to produce the error:

1. Compile all non-Petsc object code

2. Compile object code that uses Petsc using this command:

g++ -c -Wall  -I.  -I/Users/charles/pkg/petsc-2.3.3-p15
-I/Users/charles/pkg/petsc-2.3.3-p15/bmake/darwin9.5.0-c-opt
-I/Users/charles/pkg/petsc-2.3.3-p15/include ./GmresSolver.

(as mentioned, this works fine.)

3. Compile the driver, "Laplace.cc", and link it to Petsc's libraries:

g++  \
 -I/Users/charles/pkg/petsc-2.3.3-p15/  \
 -I/Users/charles/pkg/petsc-2.3.3-p15/include  \
 -I/Users/charles/pkg/petsc-2.3.3-p15/include/mpiuni  \
 -I/Users/charles/pkg/petsc-2.3.3-p15/include/petsc \
 -DPETSC_STATIC_INLINE=""  \
 Laplace.cc  \
 -L/Users/charles/pkg/petsc-2.3.3-p15 \
 -L/Users/charles/pkg/petsc-2.3.3-p15/lib/darwin9.5.0-c-opt \
 -lpetscts -lpetscsnes -lpetscksp -lpetscdm -lpetscmat -lpetscvec -lpetsc \
 BoundaryConditionFactory.o  BoundaryCondition.o Field.o FileIO.o
GmresSolver.o JacobiSolver.o Timer.o TimerFactory.o

(Note: I don't know why I need -DPETSC_STATIC_INLINE="", but I do, otherwise
I see a bunch of errors like "petsc-2.3.3-p15/include/petscviewer.h:117:
error: ‘PETSC_STATIC_INLINE’ does not name a type" - anyone know what that's
all about?)

This last compiler command gives the undefined symbols errors:

Is this a problem with my libpetsc.a?  Or is this problem because another
library is broken or not being linked to?  Any insight into this problem
would be greatly appreciated.  After several hours of trying to figure this
out I feel like I'm lost at sea.
