For now, this is a workaround.

I can confirm this patch works at samba-4.19.4.

Using regular profile with clang as default compiler and lld as default linker

I can confirm this patch still works in net-fs/samba-4.20.0

Hello, I can confirm that this fix is still possible in samba-4.20.2. Here is a way to "apply" the patch without modifying the ebuild or the samba's source code.

1) Create a file in /etc/portage/env/fix-samba-clang (the name of the file is completely optional, but it should be in the /etc/portage/env directory)

2) Inside the file, insert the following line and save the file:

LDFLAGS="${LDFLAGS} -Wl,--undefined-version"

3) Add the following line into /etc/portage/package.env file to make samba use the LDFLAGS defined above during emerge:

net-fs/samba fix-samba-clang

4) Compile samba -> it should be fine now
