I think it should be the only reason. If not, you may need to reconsider your design. Another simple option is that you build the statically linked binaries in advance for all archs that you need to support, and then copy them onto the target at rootfs time. I think multiconfig could solve your problem, but I myself haven't tried it out.

Hello,

We're building a custom image and using glibc as the standard library.=C2=A0 We have a need for a couple recipes that produce binaries that need to be 100% statically linked (using musl).=C2=A0= Is this possible to do?

Usually, it's not possible to do so.

Is this achievable with the multilib class?

No.

Is there another approach that is worth looking into or is this not possible?

You could look into multiconfig support. That may solve your problem. But it's a little hacky.

=C2=A0 It is not desirable in our case to change the default libc to musl, we'd prefer to only use musl in a couple recipes if at all possible.

Is it about license? I think it should be the only reason. If not, you may need to reconsider your design.

Another simple option is that you build the statically linked binaries in advance for all archs that you need to support, and then copy them onto the target at rootfs time.
