The only win4lin-capable kernel marked stable currently is win4lin-sources-2.6.6-r1, since win4lin-sources-2.4.26-r1 have been masked and win4lin-support is broken in gs-sources since 2.4.25_pre6 half a year ago. The latest stable win4lin version in the portage tree however is 5.0.8, which very unfortunately doesn't work with the 2.6 kernel series. According to http://www.netraverse.com/member/downloads/kernel_patch.php at least Win4Lin 5.1.10 is required to work with a 2.6 kernel. My attempt to get the 5.0.8 version working with win4lin-sources-2.6.6-r1 resulted in a "can't find /proc/ksyms" message from the Win4Lin init script and Win4Lin refusing to start (something like "The Win4lin modules haven't been loaded. Please make sure your kernel is compiled for Win4lin support.") As far as I can see it's currently impossible at all to use Win4Lin for users who stick to stable. This should be addressed.
Do win4lin-sources-2.4.26-r2 work?
No. Unforunately they fail to compile not unsimiliar to the problem that affected the gs-sources kernel series. I attached the .config used in my attempt to compile the kernel. The compilation aborts after: gcc -I. -I/usr/src/linux-2.4.26-win4lin-r2/include -D__KERNEL__ -I/usr/src/linux-2.4.26-win4lin-r2/include -Wall -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=athlon -DMODULE -DMODVERSIONS -include /usr/src/linux-2.4.26-win4lin-r2/include/linux/modversions.h -DMODULE -DMODVERSIONS -include /usr/src/linux-2.4.26-win4lin-r2/include/linux/modversions.h -c mki24.c -o mki.o mki24.c: In function `mkia_free_ldt': mki24.c:270: error: structure has no member named `segments' mki24.c: In function `mkia_alloc_ldt': mki24.c:445: error: structure has no member named `segments' mki24.c: In function `mkia_set_gdt_entry': mki24.c:812: error: structure has no member named `segments' mki24.c: In function `mkia_set_ldt_entry': mki24.c:829: error: structure has no member named `segments' mki24.c:831: error: structure has no member named `segments' mki24.c:834: error: structure has no member named `segments' mki24.c: In function `mkia_getparm': mki24.c:953: error: structure has no member named `segments' mki24.c: In function `mkia_set_private_ldt': mki24.c:1114: error: structure has no member named `segments' mki24.c:1126: error: structure has no member named `segments' mki24.c:1140: error: structure has no member named `segments' make[1]: *** [mki.o] Error 1 make[1]: Leaving directory `/usr/src/linux-2.4.26-win4lin-r2/arch/i386/mki-adapter' make: *** [_mod_arch/i386/mki-adapter] Error 2

I've done a bit of digging, and it looks like the fault is in the mki-adapter.patch that's fetched from a Gentoo mirror when emerging win4lin-sources. ---------------------- elh@preacher elh $ sudo emerge win4lin-sources Calculating dependencies ...done! >>> emerge (1 of 1) sys-kernel/win4lin-sources-2.4.26-r2 to / >>> Downloading http://gentoo.oregonstate.edu/distfiles/mki-adapter.patch --23:29:00-- http://gentoo.oregonstate.edu/distfiles/mki-adapter.patch => `/usr/portage/distfiles/mki-adapter.patch' Resolving gentoo.oregonstate.edu... 128.193.0.3 Connecting to gentoo.oregonstate.edu[128.193.0.3]:80... connected.

The revision tag above is for the mik24.c file. This is where `make modules` is is kicking out the "structure has no member named 'segments'" error. ELH
The problem seems to be... a) The mki-adapter.patch on Gentoo's mirrors is outdated, as Eric said. b) Portage searches Gentoo's mirros for the mki-adapter.patch *before* trying netraverse's site as specified in SRC_URI in the ebuild. I was able to get the mki-adapter.o module to compile by replacing /usr/portage/distfiles/mki-adapter.patch with the newest one and then executing: emerge -C win4lin-sources ebuild /usr/portage/sys-kernel/win4lin-sources/win4lin-sources-2.4.26-r2.ebuild digest emerge win4lin-sources You might have to change some stuff above if you're using gs-sources, etc. Then make modules and it should work.
Report from the field. I was able to patch the 2.6.3 gentoo-sources to add win4lin support by hand, following the directions on the win4lin website. 2.6.6 didn't work for me, and I was planning on submitting a revised ebuild when I saw this bug report. When I get home I'll cobble together my notes on what finally worked.
I've marked the 2.6 version as "~x86" now, closing bug sa FIXED.
What? It's not fixed! I, for one, am stuck on the 2.4 series because we're still using Win4lin 4 (because 5 costs more money, and I already have 4). So I'd like to use the latest version of the kernel that's available. Win4lin 2.4.26 kernels are using the wrong mki-adapter patch, and it causes compilation to fail. For my part, downloading the latest mki-adapter patch from NeTraverse worked. NeTraverse affirms that this patch is good for all the kernels. Could you update the version in portage?
As Rusty said, this has *not* been fixed, therefore I'm reopening this bug. Fixing should be very easy, since the only thing to do is to replace the old mki-adapter.patch with the one from http://www.netraverse.com/member/downloads/files/mki-adapter.patch -- I just downloaded this file to /usr/portage/distfiles, copied the Win4Lin-sources to my local portage tree, removed the digest, created a new one and remerged win4lin-sources, and et voila, the kernel compiles again. :)
