failed to build

[itrack]

Hi,
I tried nix-build but I get the following error:

[ 46%] Built target valhalla-odin
make: *** [Makefile:156: all] Error 2
error: builder for '/nix/store/qnych883vd3yly0h450q5h5l9dl59f2q-valhalla.drv' failed with exit code 2
error: 1 dependencies of derivation '/nix/store/xdi1ymjz73fj1ni2xd9rjsli8qap226x-valhalla-go.drv' failed to build

Do you have any idea what the solution could be?
Thank you!

@itrack Hi, actually, I run this on Mac and I fixed it by adding -DENABLE_SINGLE_FILES_WERROR=OFF into cmakeFlags, then it works for me. you can have a try.
