make error for example code

[jzhoulon]

when I tried to compile FFT and HPCCG, it reports error as follows, is there something wrong?

Which version of DaCe are you running? It seems indeed that with the new version of DaCe something broke. Version 0.13.3 should work fine.

@leporia thank , I switch to 0.13.3 dace and it can compile succuessfully, currently, I generated serveral sdfg(HPCCG-perf.sdfg), do I need to write a python script to load it and run or is there some tool in c2dace can convert the c to a python script automatically to use it?

[leporia]

What are you trying to do? If you want to run it you can compile the resulting C++ file or for convenience make compile includes the correct header path.

Otherwise you can load the SDFG in Python. Something like this should work

import dace
from dace.sdfg import SDFG

sdfg = SDFG("main").from_file("tmp/HPCCG-opt.sdfg")

sdfg()
