           Summary: Cannot create a 64-bit wineprefix with old wow64
           Product: Wine

Since commit cb87d40cd4a8837826ea76efc91371ab09eb9d63 I have been unable to
create a 64-bit wineprefix when I build Wine. This is running without first
using "make install".

wine: created the configuration directory '/tmp/wine/wineprefix'
wine: WINEARCH set to win64 but '/tmp/wine/wineprefix' is a 32-bit
installation.

Whereas /tmp/wine/wineprefix does not initially exist. It is created by Wine,
but then insists it's 32-bit and immediately exits.

- New wow64 works fine
- 32-bit works fine
- -O0 and -O2 make no difference
- The prebuilt debs work fine

makefiles: Create wine as a symlink to tools/wine/wine.

This commit cannot be reverted, but checking out the commit before fixes the
issue.

My process as per
https://gitlab.winehq.org/wine/wine/-/wikis/Building-Wine#shared-wow64

1. Build 64-bit-only
2. Build 32-bit
3. Build 64-bit-wow

This is the same process I have always used.

I know there's been a number of changes in this area so I don't know how to
work around it.

In all cases I use Debian Stable chroots (with schroot) but the same result
using Debian Testing.

If it's me doing something stupid then I apologise in advance.

Console

I missed an important point:

wineboot = OK
WINEARCH=win32 wineboot = OK
WINEARCH=win64 wineboot = fail
WINEARCH=wow64 wineboot = fail

So it's when WINEARCH is forcing a new 64-bit wineprefix.

Also, I tried with-mingw and without-mingw and it makes no difference.

It's hard to tell without seeing the details of your chroot, but it sounds like
the 32-bit build doesn't see the 64-bit one. Are you running from the wow64
build dir? You should have a loader-wow64 symlink in there.

Directory tree

I've attached some text from my mad ramblings at
https://forum.winehq.org/viewtopic.php?p=147464#p147464 and the view of the
tree from within the chroots used. I don't know if any of it is of any use.

The builds take place in the chroots and they can see each other. They don't
run in the chroots though, I run them directly (Ubuntu). It's always worked
well.

> Are you running from the wow64 build dir?

Sorry, I didn't answer that.

I am running wine64/wine (the wow64 build).

I see, that's because the wine symlink points into the 32-bit only dir. You
probably need to build that one as wow64 too, or else run wine from the
wine64only dir.

Running from wine64only does indeed work! Tested with 32-bit and 64-bit
programs and everything is back to normal.

Does that make this an invalid bug? The behaviour has changed, apparently.
Assuming I was compiling correctly in the first place (I did use the [old] Wiki
as a guide).

The documentation (Wiki) does need updating. I'll look at that later if someone
doesn't beat me to it. (Please beat me to it)

I've added e6677fe356686186ac7b75552f2263f035360d47 which makes it possible to
use --enable-tools in the wow64 tree instead of using a separate 32-bit tools
tree.

Resolving FIXED, though it could as well be marked INVALID, it's more a
documentation issue than a real bug.
