Hello, thanks for putting this repo up. I've managed to get most of the dependencies installed and issues worked out, but now getting the following compile issue after running make (on osx 10.10.1):

[ 44%] Linking CXX executable FractureBEM_vis
Undefined symbols for architecture x86_64:
  "openvdb::v2_2_0::initialize()", referenced from:
      FractureSim::VDBWrapper::VDBWrapper(double, double, bool) in libFractureLib.a(VDBWrapper.cpp.o)

      ...

  "openvdb::v2_2_0::GridBase::getName[abi:cxx11]() const", referenced from:
      FractureSim::VDBWrapper::getSegments(double, bool) const in libFractureLib.a(VDBWrapper_mesh.cpp.o)
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
make[2]: *** [FractureBEM_vis] Error 1
make[1]: *** [CMakeFiles/FractureBEM_vis.dir/all] Error 2
make: *** [all] Error 2

Any advice for solving this? My guess is there is as issue of the openVDB installation, althoguth not sure how I would check. I do have openvdb 2.2.0 installed. I'm also assuming osx binaries arn't available. Although that would be great.

The full output and other relevant files are attached

Thanks again,

Hello again, unfortunately more Ubuntu issues. Both examples are crashing for me.

Taken from the .bat files I have run both verbatim

FractureRB bowl.bullet bowl.csv -o out/bowl -n 500 -i 1e3 -f 5e6 --default-solver

as well as

FractureRB glass.bullet glass.csv -o out/glass -i 1e5 -f 1e7 -s 2

bowl one raises

...

This may be a / issue? should it be vdbmat/grains?

and the glass one raises

These both crash at the same place if re-run.

I am running the version with the bug fixes you pushed this morning. I did not recompile openVDB with the fix but I I saw it causes crashes with stack limits and mine is 1,000,000 so that should be fine.

Thanks again for your help! I look forward to being able to use this.

Hello David!

I noticed that the source code for the HyENA library is not provided in your project, and the link given in your README is no longer valid. Could you please provide the source code for this library?

Thanks,
KL

Hello,

Pardon the installation question but I'm unable to get past one of the final make linking steps.

Here is one of them:

CMakeFiles/FractureRB.dir/src/FractureRB_fragments.cpp.o: In function FractureSim::FractureRB::doCollisionUpdate()': FractureRB_fragments.cpp:(.text+0x17a4): undefined reference tobtRigidBody::setMassProps(double, btVector3 const&)'

Bullet is successfully installed and pasts tests, I have also tried with various releases of the bullet library. BULLET_COLLISION path is definitely correctly set to the libBulletCollision.so file and BULLET_INCLUDE is correct as well. I also tried using the .a files. FractureBEM and FractureBEM_vis successful link.

Before I started muckign around with the make file I was wondering if this was an issue you were aware of or knew how I might remedy it. I've already tried everything else I know of. I am on ubuntu.

The full output is attached.
Thanks a lot!
