error while loading shared libraries: libmkl_intel_lp64.so

Hi,

Thank you for releasing the codes. I met problem with marching cube at last of the demo, the error is:

./isosurface/computeMarchingCubes: error while loading shared libraries: libmkl_intel_lp64.so: cannot open shared object file: No such file or directory

However I’ve tried many methods to reinstall mkl, add this file to lib path and even move it to the same folder with computeMarchingCubes, neither of these methods work.

Any idea on solving this would be appreciated.

Thanks!

I think you can modify LIB_PATH to correct mkl path. The LIB_PATH provided by the author is set to author’s path, which is not correct. However, the author has provided a link library available in this github repo, which is in the current folder path.

Maybe you can try this: ./isosurface/tbb/tbb2018_20180822oss/lib/intel64/gcc4.7

Thanks to @qiao1025566574 for providing an alternative to the original method. I have made slight changes based on his suggestion and seems to fix the issue. Everything works nicely afterwards. In the demo.py script, I have changed the create_obj function as follow:

def create_obj(pred_sdf_val, sdf_params, dir, i):
    import mcubes
    new_dim = int(pred_sdf_val.shape[0] ** (1.0 / 3)) + 1
    u = pred_sdf_val.reshape(new_dim, new_dim, new_dim)
    vertices, triangles = mcubes.marching_cubes(u, 0)
    mcubes.export_obj(vertices, triangles, "demo/result.obj")
