When I remove all "restrict" keyword in _kdtree_code.c, setup.py working well. But I have new error in generate.py

And I also edit name of struct in _kdtree_core.c 

typedef struct
{
...
} Node_float;

to

typedef struct Node_float
{
...
} Node_float;

When I replace all "restrict" to "__restrict", it also working well. But I still get an error in generate.py.

Hi, have you in the meantime found a way to solve this issue?

Hi, have you in the meantime found a way to solve this issue?

No I don't yet

ShunChengWu commented 3 years ago

Pytorch tries to use c++ compiler to compile a c project. an easy hack for this is to set your CXX to gcc CC=gcc CXX=gcc python setup.py build_ext --inplace

of course, this may cause errors on other modules. try to compile them separately. i.e. comment out pykdtree first and run
python setup.py build_ext --inplace, then comment out all others except pykdtree and run again with CC=gcc CXX=gcc python setup.py build_ext --inplace

DaddyWesker commented 2 years ago

I have the same error. Unfortunately, easy hack mentioned above doesn't work either. I've managed to run python setup.py build_ext --inplace after commenting pykdtree in ext_modules, but i am unable to build kdtree separately.
