Standalone Compilation of Examples Fails

[Travis Chapman]

Hi,

I am able to successfully install deal-ii with petsc, p4est and metis, and am able to run the examples that use those libraries after the installation finishes.

And yet, when I try to compile those same examples separately, i.e., if I copy them to some other path and do, for example:

cd step-2/build

cmake .. -DDEAL_II_DIR=path/to/deal-ii/install

make,

then the compilation fails during the linking phase. A brief snapshot of the errors is copied below.  Please advise, how do I fix this?

Error message (partial):

CMakeFiles/step-2.dir/step-2.cc.o:step-2.cc:function tbb::detail::d1::task_group_context::~task_group_context(): error: undefined reference to 'tbb::detail::r1::destroy(tbb::detail::d1::task_group_context&)'

Travis,
I don't know what exactly it is that is going on here. It *looks* like a
mismatch in the versions of the Threading Building Blocks that are used when
you are building in the two directories, but I'm unsure how or why. You may
want to compare what the exact compile and linker lines are when you compile with
make VERBOSE=1
in the two directories. (I assume that the issue happens during linking, not
when you execute the program.)

Best
W.
