Dear libMesh developers, For certain reasons, I need to compile a 32-bit libMesh on a 64-bit machine. What I did was: 1. I compiled mpich2 in 32 bit mode, i.e. by saying export CFLAGS=-m32 export LDFLAGS=-m32 export CPPFLAGS=-m32 export FC=gfortran export F90=gfortran export FFLAGS=-m32 export F90FLAGS=-m32 prior to configuring mpich2 (without problems). 2. I compiled PETSc-2.3.3-p11 against that mpich2 (without problems). 3. I set the above variables again, before calling libMesh's "./configure". 4. I said "make" in the libMesh directory. What I get is: src/geom/elem_refinement.C: In member function ‘unsigned int Elem::_cast_node_address_to_unsigned_int(unsigned int)’: src/geom/elem_refinement.C:160: error: cast from ‘Node*’ to ‘unsigned int’ loses precision It seems to me that libMesh configured for 32-bit mode (in particular determining LIBMESH_SIZEOF_INT and LIBMESH_SIZEOF_VOID_P to be equal), but then compiled without the "-m32" option. This is confirmed by saying "make -n" and observing that the command to be executed does not contain "-m32". What did I do wrong?
