And when building the hexagon_api, the problem is:

try to delete the space in "",like [asm volatile(" dmlink(%0, %1)" : : "r"(tail), "r"(next));] to [asm volatile("dmlink(%0, %1)" : : "r"(tail), "r"(next));]

You are probably using a wrong compiler. It is recommended to use the Hexagon docker image to avoid issues like this.
