There is an error when building docker:

I can't seem to reproduce this error: ``` ---> c215d77c7ff4 Step 10/15 : FROM scratch ---> Step 11/15 : COPY --from=builder /builddir/sslscan /sslscan ---> 49d45d65664c Step 12/15 : COPY --from=builder /lib/libz.so.1 /lib/libz.so.1 ---> e0c99f39eba2 Step 13/15 : COPY --from=builder /lib/ld-musl-x86_64.so.1 /lib/ld-musl- x86_64.so.1 ---> 6b63a33358a0 Step 14/15 : USER 65535:65535 ---> Running in 1843bec11fce Removing intermediate container 1843bec11fce ---> 7b696eb989b1 Step 15/15 : ENTRYPOINT ["/sslscan"] ---> Running in fb3ef2ddfd7f Removing intermediate container fb3ef2ddfd7f ---> cded6018ffc1 Successfully built cded6018ffc1 ``` This is using the `master` branch of sslscan, along with Docker v24.0.5. What code branch and Docker version are you using?

    Fixed cipher enumeration against servers that require unsafe legacy renegotiation.

I am working on Mac OS M1 Max, Sonoma 14.1.2.
My Docker version is 24.0.6, build ed223bc.

I did run again and got the same:

Does ld-musl-x86_64.so.1 exist in the alpine:latest Docker image for you? The build works fine on for me on x64 Kali Linux - so I presume this is an OSX/M1 related problem?

[jtesta]

It just occurred to me: alpine:latest is likely the ARM build on MacOSX/M1, whereas its x86_64 on our machines. Hence, there is no ld- musl-x86_64.so.1 on ARM; its probably called ld-musl-arm.so.1 or something. @derekmizak: on line 26 of the Dockerfile, could you change it to read "COPY --from=builder /lib/ld-musl-*.so.1 /lib/" and try again?

[derekmizak]

@jtesta - it worked. Thank you. All is fine - can be closed.
Line 26 of Docker file changed to:

COPY --from=builder /lib/ld-musl-*.so.1 /lib/

[rbsec]

@derekmizak that should be merged into master now.

@jtesta, I suspected that it would be something like that when I saw the error - but TBH I've never really looked at the ARM docker images.

[derekmizak]

It is fixed - thank you.
