[SOLVED] Bubblewrap claims wine doesn't exist

lfitzgerald · 2021-10-19 00:12:32

I have wine installed at /usr/bin/wine and want to use it for windows games. On its own, "wine game.exe` works fine. But when I use bubblewrap it claims that wine is not installed. I assumed that the problem is that I was missing some mounts. I tried a bunch of things, I think this is the most comprehensive version:

bwrap \
    --ro-bind /bin /bin \
    --ro-bind /lib /lib \
    --ro-bind /lib64 /lib64 \
    --ro-bind /root /root \
    --ro-bind /run /run \
    --ro-bind /sys /sys \
    --ro-bind /sbin /sbin \
    --ro-bind /usr /usr \
    --ro-bind /etc /etc \
    --dir /tmp \
    --dir /var \
    --proc /proc \
    --dev /dev \
    bash

Which gives me a bubblewrapped prompt. If I then type "wine" I get "bash: /usr/bin/wine: No such file or directory". However if I do "ls /usr/bin/win*" I can see that wine is clearly there. Also "winecfg" gives "/usr/bin/winecfg: line 46: /usr/bin/wine: No such file or directory" - so even "winecfg" is clearly there, but they're refusing to see wine. I can even do "stat $(which wine)":

  File: /usr/bin/wine

So what's going on here?

Well, let's see:

$ ldd /usr/bin/wine
        linux-gate.so.1 (0xf7f6d000)
        libpthread.so.0 => /usr/lib32/libpthread.so.0 (0xf7f0f000)
        libdl.so.2 => /usr/lib32/libdl.so.2 (0xf7f09000)
        libc.so.6 => /usr/lib32/libc.so.6 (0xf7d10000)
        /lib/ld-linux.so.2 => /usr/lib/ld-linux.so.2 (0xf7f6f000)
$ readlink -m /lib/ld-linux.so.2
/lib32/ld-linux.so.2
$ ls /lib32/ld-linux.so.2
ls: cannot access '/lib32/ld-linux.so.2': No such file or directory

So that means you're missing /lib32, which you haven't mounted.
The error message is a bit misleading, it's the dynamic linker that's missing, not the wine executable.

That would make a lot more sense. Thanks for the hint, I didn't know about ldd.

But /lib32 is missing on the main system as well, and wine runs happily outside the bubblewrap (bw.sh is a wrapper for the command I posted above):

$ wine --version
wine-6.17
$ ls / | grep lib
lib
lib64
$ bwrap \
    --ro-bind /bin /bin \
    --ro-bind /lib /lib \
    --ro-bind /lib64 /lib64 \
    --ro-bind /root /root \
    --ro-bind /run /run \
    --ro-bind /sys /sys \
    --ro-bind /sbin /sbin \
    --ro-bind /usr /usr \
    --ro-bind /etc /etc \
    --dir /tmp \
    --dir /var \
    --proc /proc \
    --dev /dev \
    bash
$ ls | grep lib
lib
lib64
$ wine --version
bash: /usr/bin/wine: No such file or directory

Maybe try to use symlinks for the directories in the root that are symlinks in arch

--symlink /usr/lib /lib
--symlink /usr/bin /bin
...

Yes, using mountpoints isn't the same as symlinks.
In the "real" environment, /lib is a symlink to /usr/lib, which means /lib/../lib32/ld-linux.so.2 resolves to /usr/lib/../lib32/ld-linux.so.2, which is /usr/lib32/ld-linux.so.2
In the example /usr/lib is mounted to /lib (the fist argument to --mount is resolved!), so from there ../lib32 resolves to /lib32.
So yea, use symlinks where the host environment does.

Ah, the symlinks were indeed the problem! Specifically, instead of mounting /lib you have to symlink it. The /bin symlink seems to not be necessary for this case (although obviously there may be other problems cause by not symlinking /bin as well).

Here's a full MWE for the next person who googles this:

$ cat ./bwf.sh 
#!/usr/bin/env sh
#
# MWE for https://bbs.archlinux.org/viewtopic.php?id=270540

bwrap \
    --ro-bind /bin /bin \
    --ro-bind /lib64 /lib64 \
    --ro-bind /root /root \
    --ro-bind /run /run \
    --ro-bind /sys /sys \
    --ro-bind /sbin /sbin \
    --ro-bind /usr /usr \
    --symlink /usr/lib /lib \
    --ro-bind /etc /etc \
    --dir /tmp \
    --dir /var \
    --proc /proc \
    --dev /dev \
    bash

$ ./bwf.sh 
$ wine --version
wine-6.17

I still have to confirm that all the other stuff like graphics and sound are working, but once I do I think I'll add the wine example to the wiki. For the purposes of this thread though I think the problem is solved.
