Hi,

Running latest Mythic with latest Merlin. Unable to build Merlin payload for windows and linux. I see following error during payload build process:


Sending Build command
there was an error compiling the agent
StdErr: 
exit status 1

@timukas I'm taking a look at this now

@timukas I pulled down and installed Mythic, the http C2 profile, and Merlin from source today. After installing them I was able to create an agent without errors.

The error you provided looks like we've modified the go.mod file to reference files in the container. Likely from our conversation at https://github.com/MythicAgents/merlin/issues/17. I removed those directories from the latest commit https://github.com/Ne0nd0g/merlin-docker/commit/6deaf8fb3c1ee15c173f5c3d7dd7f5d0407e1ed0 because they were not necessary and they bloated the image size. As a temporary workaround, you could add the instructions back to your local copy of the Dockerfile in Payload_Type/merlin/Dockerfile like this:

# Clone Merlin Agent
WORKDIR /opt/
RUN git clone -b v2.4.1 https://github.com/Ne0nd0g/merlin-agent
WORKDIR /opt/merlin-agent
RUN go mod download
