Building extension error: 'isnan' is not declared in this scope

[LeoZDong]

Hi,

I installed the dependencies as required and tried to build the extensions via python setup.py build_ext --inplace. But I get the error: im2mesh/utils/libmise/mise.cpp: In function ‘PyObject* __pyx_pf_7im2mesh_5utils_7libmise_4mise_4MISE_6to_dense(__pyx_obj_7im2mesh_5utils_7libmise_4mise_MISE*)’: im2mesh/utils/libmise/mise.cpp:4126:249: error: ‘isnan’ was not declared in this scope */ (( /* dim=0 */ (__pyx_v_out_view.data + __pyx_t_24 * __pyx_v_out_view.strides[0]) ) + __pyx_t_25 * __pyx_v_out_view.strides[1]) ) + __pyx_t_26 * __pyx_v_out_view.strides[2]) )))) != 0);

and many other subsequent errors taht all said "‘isnan’ was not declared in this scope."

Any idea why this is happening?

Thanks a lot!

Seems like I have to manually replace all isnan in mise.cpp with std::isnan. This worked for me.
