Error during compilation

[rbfp]

Using the docker I've seen this come up a few times during compilation using different shellcode_types..Here's one example:

python3 Boaz.py -f /host_home/boaz_dock/payload_64.exe -o /host_home/boaz_dock/boaz8.exe -l 1 -t rc4 -c akira

Please advise on how to fix or does the docker method not work? thank you!
