Sure, will try that next, although I claim the stack trace will be no more
illuminating ;-)
And in case anyone's curious, here are the different link lines used in the
automake and trunk checkouts (with some stuff removed for readability)
Automake:
--------
/bin/sh ./libtool \
--tag=CXX \
--mode=link \
mpicxx \
-O2 \
-felide-constructors \
-funroll-loops \
-fstrict-aliasing \
-std=c++0x \
-Wdisabled-optimization \
-fopenmp \
-o libmesh.la \
(various .lo objects) \
(various .la objects) \
-lz \
-L/opt/packages/petsc/3.3-p4/lib -lpetsc \
-L/opt/packages/hypre/2.8.0b/lib -lHYPRE \
-L/opt/packages/mpich2/mpich2-1.4.1p1/lib \
-L/opt/packages/gcc_4.6.3/lib/gcc/x86_64-apple-darwin12.0.0/4.6.3 \
-L/opt/packages/gcc_4.6.3/lib \
-lflapack -lfblas -lmpichf90 -lpthread -lgfortran \
-lquadmath -lm -lmpichcxx -lstdc++ -lpmpich -lmpich \
-lopa -lmpl -lSystem -lgcc_ext.10.5 -ldl
Trunk:
------
libtool \
--tag=CXX \
--quiet \
--mode=link \
mpicxx \
-dynamiclib \
-Wl,-undefined,dynamic_lookup,-flat_namespace \
-o
/Users/moose/projects/libmesh/lib/x86_64-apple-darwin12.0.0_opt/libmesh.dylib
\
(various .o files) \
-Wl,-undefined,dynamic_lookup,-flat_namespace
So I'd say the important differences are the following:
1.) The libtool used (trunk uses my hand-built one, automake uses one that
has been generated in libmesh's top-level directory)
2.) automake branch passes more system libraries on the link line
( -lSystem, -lgcc_ext.10.5, -ldl, -lgfortran) than trunk.
I guess next I'll try to have my hand-built libtool (rather than libmesh's)
first in my PATH, see if that makes a difference...
