Bug ID: 59080
           Summary: 64-bit Linux wine-loader requires 32-bit dynamic
                    linker
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: loader
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

As of
https://gitlab.winehq.org/wine/wine/-/commit/8c3f205696571558a6fae42314370fb...
(since wine 10.2), the loader defaults to the 32-bit loader, however this
requires the 32-bit dynamic linker to be present (e.g. `/lib/ld-linux.so.2`). I
feel this is undesirable; I had to install multilib files (32-bit glibc) to be
able to run wine correctly. Note that I encountered this issue using
pre-compiled wine binaries distributed as part of the Firefox cross-compile
toolchain. I didn't look too deeply (but didn't see anything as part of that
commit), but if there's some wine compile-time checks which determine whether
this behavior occurs, perhaps that is to blame (e.g., if the server which
compiled the wine toolchain had multilib files). Maybe this behavior should do
a quick sanity check (like looking for the presence of `/lib/ld-linux.so.2`)
before switching to the 32-bit loader?

If you don't have 32-bit support you can force new wow64 mode with
WINEARCH=wow64. Presumably the Firefox toolchain could be compiled for new
wow64 mode as well.
