$ wine cb70i.exe
i386_set_ldt: Invalid argument
Did you reconfigure your kernel with "options USER_LDT"?
This error message is not helpful, as that kernel option is no more available since FreeBSD 5.
Strangely enough, the error only occurs on my laptop (FreeBSD 11.1-STABLE #1 r32t738 with i386-wine-2.0.3,1 or i386-wine-devel-2.21,1), but not on my desktop PC (FreeBSD 10.3-STABLE #1 r314643 with i386-wine-1.8.5,1).
Is this issue specific to cb70i.exe (what is that program?), more generally an issue (i.e. running winecfg)?
I can confirm i386-wine runs on 11.1-p1 without issue.
I get this error with all DOS programs and some Windows programs. winecfg runs without errors. cb70i.exe is the executable of the ChessBase 7.0i application (18 or so years old). I have uploaded a partial installation (sufficient to check if the error occurs) to http://steige.info/austausch/cb.zip (6 MB). If you don't get the error, it will ask you for the original CD. (That's the copy protection.)
On FreeBSD 11.1-p4 I get to the CD prompt screen, no error as described below. Would you be able to test with a FreeBSD 11.1 kernel?
I did test it with 11.1, as that's the OS version currently installed on my laptop where the error happens (see first message). I guess that some old files may be left somewhere in the file system, particularly wine configuration files and directories, that might influence the outcome of wine running.
I can try to update my desktop OS (and wine version) too and see if I run into the same error there (with similar old config files left). Currently, all Windows programs seem to work on the desktop (10.3 kernel), while DOS programs don't ("Data segment size exceeds process limit") - but that would be another issue.
I just tried with 11-STABLE (FreeBSD 11.1-STABLE #0 r326821) and I was unable to reproduce the error.
Yes, the data segment size issue in unrelated - I believe Gerald has fixed this a few releases back.
Please update you kernel and packages, maybe that fixes it? Also, are you using binary base/packages or compiling things yourself?
Meanwhile I upgraded my desktop OS from FBSD 10.3-STABLE to 11.1-STABLE and the i386-wine port too, with the result that I get the same error on the desktop too.
I use to compile everything from source. The i386-wine port, however, just installs a binary package. Maybe that's the problem. I could not find the error message anywhere within /usr/src, but it is contained in the libwine.so binary. This error message should not be there. It should not be compiled in, at least not with that text.
The code in question (responsible for this message) is
#elif defined(__NetBSD__) || defined(__FreeBSD__) || defined(__FreeBSD_kernel__)

The last changes relevant to BSDs have made in 2012. Of the three changes
since then, two were Linux-specific and one add GNU/Hurd support.
So I'd guess something is special about your system, Friedrich? Any
non-standard kernel options? Security settings?
I am not aware of anything special. Now I played around on my laptop:
11.1-STABLE GENERIC kernel => error
11.1-STABLE GENERIC kernel and running wine as root => same error
10.x-STABLE GENERIC kernel => works
As the first error line says "invalid argument", I assume that the i386_set_ldt() function throws an EINVAL error. This should be easy to debug, but I guess that a 32-bit wine within FreeBSD/amd64 needs a cross-compiler to compile?
The i386_set_ldt() function seems to be defined in /usr/include/x86/sysarch.h and implemented in /usr/src/lib/libc/i386/sys/i386_get_ldt.c, which calls sysarch() which in turn is implemented in /usr/src/sys/i386/i386/sys_machdep.c. I set DEBUG to 1 in that file, inserted additional printf's and reinstalled world and kernel, but all of that did not make the debug output appear.
Hi Friedrich, would you please attach your /etc/make.conf, /etc/sys.conf and kernel configuration (if you are not using GENERIC). Given that is works on our systems the issue is likely a local change on your side. Lets try isolate it.

There is no /etc/sys.conf. I have attached /etc/sysctl.conf instead, but only for the desktop computer. The sysctl.conf on the laptop contains comments only.
Hmmm, this is an interesting nut to crack. It would be interesting to know what errno(2) is set to. I agree with Gerald that the message wine gives is the opposite of useful.
Given that a GENERIC kernel does not work, I can suggest the following:
a) try the binary kernel provided by  (if you didn't do this already)
b) try the binary base (and lib32_ provided by 
c) try a kernel compiled without CPUTYPE?=core2 in make.conf
d) try a base work compiled without CPUTYPE?=core2 in make.conf
Please also try steps a, b and c, d together (i.e. both kernel and base either binary or compiled without CPUTYPE?=core2).
My thinking is a compiler error (when CPUTYPE?=core2 enables some extract instructions and optimisations) is causing the problem. I'm sure that wine is not the program - unless you are compiling your own version using WINE_CROSS_BUILD=yes?
errno(2) is EINVAL (invalid argument), see above. The question is: which parameter is invalid and why. In order to debug this, I would certainly need to cross-compile wine myself. I tried that with CFLAGS="-m32 -march=i686 -mmmx -msse -msse2 -mfancy-math-387 -DCOMPAT_32BIT -L/usr/lib32 -B/usr/lib32" ./configure --without-freetype && make, but /usr/local/bin/ld complained about incompatible libgcc and libc.
What is ""? Did you intend to supply an URL?
I tried out (c) and (d), i.e. new world+kernel with the CPUTYPE line commented out in make.conf. Same error.
Sorry,  is https://download.freebsd.org/ftp/snapshots/amd64/11.1-STABLE/
So rebuild i386-wine you need to:
- create an i386 chroot/jail
- in that chroot/jail run:
# make -C /usr/ports/emulators/i386-wine-devel -DWINE_CROSS_BUILD
The resulting package can be installed on amd64 (you will need to use the '-f' option as the architecture will be incorrect in the package).
Would you please also post your /boot/loader.conf file.
I'm able to reproduce the issue on an up-to-date 11-stable GENERIC kernel.
This is on an amd64 box (Intel SandyBridge with integrated graphics card).
Booting my previous kernel (11-stable (r324724) from 2017-10-18) with new
userland and without altering any of the config files the problem's gone.
That may help narrow down the possible regression window. The port I'm
using is emulators/i386-wine-devel and this happens with several games.
My config is fairly conservative, with the possible exception of make.conf:
I also happen to have the latest version of sysutils/devcpu-data installed.
/boot/loader.conf on desktop:
/boot/loader.conf on the laptop contains comments only.
concerning (a) in comment #16: same error with binary kernel. I have not tried (b) as I am afraid it might overwrite some of my config.
Preparing the jail and the required ports within it took some time, but I finally succeeded. First results: In the line
ret = i386_set_ldt(index, (union descriptor *)&entry_copy, 1)
index is 512, and ret is set to -1.
According to my regression tests the breakage was introduced on 2017-10-22 with revision 324855:
Assign to kib, as the committer of the commit. kib, in summary:
- wine started failing on FreeBSD 11-Stable with a failed call to i386_set_ldt
- in this case 'index=512' is causing the problem
- the issue appears to have been introduced in r324855
The change in question is https://svnweb.freebsd.org/base?view=revision&revision=324302. Temporarily setting max_ldt_segment back to 1024 works around the problem (but I doubt that this is the solution).
I wonder if there's a sane way to ensure the index remains below 512 without introducing other nasty side-effects...
max_ldt_segment=1024 fix this problem.
May be solution is update post install message for wine ports with text like:
If you get message: "Did you reconfigure your kernel with "options USER_LDT"?"
then add to /boot/loader.conf
this fix problem.

post install message update
I met this problem too, however setting max_ldt_segment=2048 in /boot/loader.conf didn't helped me. Any ideas?
Thanks for proposing this patch!
From a language and formatting perspective, instead of
To fix message: "Did you reconfigure your kernel with "options USER_LDT"?"
add to /boot/loader.conf
I suggest something a little different:
If you receive a message of "Did you reconfigure your kernel
with "options USER_LDT"?" add the line
to /boot/loader.conf and reboot.
David, you're a native speaker, what do you think? Since it seems
to help some users, I'm fine making this change if you agree, i.e.,
Approved: gerald (maintainer) - and I can also apply once we have
That said, kib@, this being a regression caused by your commit
can you please look into this?
(In reply to Gerald Pfeifer from comment #29)
Look at what ?
The decision to provide default max LDT size 512 is backed by the fact that a segment descriptor size is 8 bytes, and LDT must be contiguous in the KVA. The consequence is that if we allow more that 512 descriptors by default, we must allocate two or more contiguous page frames. This can break in situation where KVA is highly fragmented due to the load.
So the default is on the upper safe limit, and if user is confident that she both needs it and that the machine load would not cause the fragmentation, there is the knob to adjust it. That said, I do not believe that there are legitimate use cases when single process needs more that dozen or two segment descriptors, so 512 should be ample.
If the process does need so many descriptors, the limit is bumped, and you get some error, then it is almost certainly unrelated both to the limit and to the commit. Start debugging it, perhaps look at the failing syscall arguments to see what is going on (ktrace/truss).
I take it, no one is going to debug Wine, so let's just commit pkg-message patch.
dbn@ can you give your + on https://bz-attachments.freebsd.org/attachment.cgi?id=193326 ?
I'll take care of the wine and wine-devel ports in a minute and can
than also take care of dbn's ports later on unless he does.

David, will you be taking care of the i386*wine* ports, or shall I?
Gerald, please will you take over maintainership of the i386-wine ports. I sent you an email with the information I have.
