Dear Yumi,

in the first case (error_log_solving_DLP_on_arm.txt) I see in the log file:

Error:Linear Algebra: Unsupported combination: group size =
1, p =
37858785688058251908976098251106649423874744726099768156267414181577309352921,
4 limbs

It seems you are trying to run the generic mpfq code (pz) whereas your number
has only 4 limbs, thus you should use COMPILE_MPFQ_PRIME_FIELD_p_4.

Best regards,
Paul
