edit the function in file named polar_decoder_common.cc, as following
void polar_decoder_common::butterfly_volk(float* llrs, unsigned char* u, const int stage,
const int u_num, const int row)
{
volk_32f_8u_polarbutterfly_32f(llrs, u, block_power(), stage, u_num, row);//volk_32f_8u_polarbutterfly_32f(llrs, u, block_size(), block_power(), stage, u_num, row);
}
it can pass the building but I am not sure the correct results!!!!
