Do you have the _latest_ kernel-headers 2.6 installed? (sys-kernel/linux-headers-2.6.0) Does this problem occur when trying to install bootsplash-0.6-r3?
Yes, I believe so. Although I'm using a slightly hacked (to change the keywords from -* to ~x86) version of the ebuild I've diff'd it against the version in the main Portage tree (and diff'd the patches as well) and the only major change recently has been the update of the copyright dates. bootsplash 0.6-r3 used to fall over and die as well. I got around that by temporarily emerging some 2.4 headers, compiling bootsplash and then re-merging the 2.6 headers but I'd really love to avoid that this time around.
Oh believe me, I'd very much like to have it fixed, too :) The strange thing about this bug is that I'm using almost exactly the same configuration and everything works fine here. Please send me your linux/fb.h file and try to download the attached fb_test00.c and compile it with 'gcc -O2 -Wall -o fb_test fb_test00.c'.

Yeah, it's weird. I've read posts on the boards saying people have it working but for some reason, it refuses to on my system. This isn't the only package I've had this kind of trouble with either with both svgalib and DirectFB both complaining when trying to compile under the 2.6 headers. DirectFB is even more wierd as I'm positive it compiled in the first build I made against the 2.6 headers but refuse to in this one. Anyway, back to bootsplash. This is the output I get from your little test: gcc -O2 -Wall -o fb_test fb_test00.c In file included from fb_test00.c:2: /usr/include/linux/fb.h:345: error: syntax error before "atomic_t" Same error in the same place as when trying to compile bootsplash. As for my fb.h, I put it up for download here when I made a thread about this on the boards: http://www.westnet.com.au/gweber/fb.h Hopefully it'll provide some insight into the problem.
Hang on, my ISP is still whacked. The file *is* there as I can access it via FTP but HTTP access to it is screwed. I'll have to email it to you. It should be there in a few minutes.
Ok, that was exactly what I expected :/ It's not a kernel/bootsplash bug alright, it has to be smth else. Please run 'gcc -E -Wall -O2 fb_test00.c -o fb_test00.pre' and have the fb_test00.pre file sent to me. Maybe this will make things more clear here.

This is most likely a gcc bug. The kernel headers are the same, the bootsplash code is fine, but the preprocessed code generated by GCC is different. My idea for now is to try to reemerge gcc, possibly with "safer" flags (let's say CFLAGS="-O2" only).
I tried using less agressive CFLAGS. First stripping out everything except -march=athlon-xp, -O3, -fomit-frame-pointer and -pipe but when that didn't work, recompiling with just -O2 as you suggested but got the same results with that as well.
Ok, obviously it's not the cflags then. I've seen similar issues reported (bugs #38737, #37812) and one thing that I noticed everyone experiencing this problem had in common was having the 'nptl' flag. Could please try removing it from your USE var and then recompiling glibc and gcc? I have no idea if it helps, but it's my best guess for now.
I don't use the 'ntpl'-USE-flag and it still doesn't compile.

can one of you try the patch I just attached? # cd /usr/include # patch -p0 </path/to/fb_h.patch then try to emerge bootsplash?
Works like a charm here. Thanks. I wasn't particularly looking forward to having to rebuild my system to get rid of NPTL support. I might even try re-emerging DirectFB later too see if this patch cures the problem I was having with that as well
Please rsync and reemerge linux-headers-2.6.0 (there's a new patch included) and then try to compile bootsplash/directfb.
Closing, as this is now fixed in Portage.
