you neglected to provide helpful output about your system ...

we'll need:

I'm having the same problem here.

Fixes the compile problem "redefinition.." whith installed linux-headers-2.6

This patch should fix the compile problems on boxes with linux-headers-2.6.x,
the patch should be also working if linux-headers-2.4.x are installed.

Updated patch

I just updated my patch, it had a little bug in it which could break
acceleration on some cards, that use ROP_XOR, so here is the patch that should
fix compile with linux-headers 2.6.x and it is still compatible with headers
2.4.x

Hi Aleksandr, I just checked, if there is a redefiniton of :

"kernel26compat.h:17: redefinition of `irqreturn_t'"

this is done in gentoo patch, svgalib-1.9.17-linux2.6.patch, this error doesn't occur on my box with 2.6 headers, 

sh-2.05b# grep -r 'irqreturn_t' *
svgalib-1.9.17-linux2.6.patch:+typedef void irqreturn_t;
svgalib-1.9.17-linux2.6.patch:+static irqreturn_t vsync_interrupt(int irq, void *dev_id, struct pt_regs *regs)
sh-2.05b#

So I guess there is a little bug in svgalib-1.9.17-linux2.6.patch

Can someone fix it his code and update the patch, with out testing -->I think this should work(undefining irqreturn_t and then define it:



#ifdef irqreturn_t
#undef irqreturn_t
+typedef void irqreturn_t;

a really bad-boy solution ... ;o)

This is the same problem as described in
http://bugs.gentoo.org/show_bug.cgi?id=35348, but this time for gs-sources!

Also problem with 2.6 kernel headers, mm-sources-2.6.1-r1, gcc-3.2.3-r3,
glibc-2.3.2-r3:

*** Bug 38690 has been marked as a duplicate of this bug. ***

could all you users of linux-headers-2.6.x please try `emerge sync` and then
re-emerge linux-headers to see if this is still a problem ?

as for Aleksandr and Peter, you guys have different bugs that are resolved if
you update your kernels properly

Petter: I think you need to enable the CPU type in mm-sources or else it won't
compile by itself either, that's an -mm bug. Either way, enabling
`CONFIG_X86_L1_CACHE_SHIFT' should work.

Bob, you might to have a look at this in gs-sources and add a patch comment out
the offending lines - they're not yet in vanilla and headers should be kept
more-or-less constant between kernels.

plasmaroo: looking in my config i find:
CONFIG_X86_L1_CACHE_SHIFT=7
Both in the kernel I'm running since this afternoon (mm4) and in the one I used filing the report in comment #9. Can't find where it hides when running 'make menuconfig' though...

I've upgraded to mm-sources-2.6.1-r4, removed nptl from my use flags (since it had some problems for other ebuilds), reemerged the linux-headers-2.6.0, reemerged glibc (twice) and reemerged the packages that was affected by the nptl-flag still no success :(

If it's to any help, I've successfully emerged svgalib with the redifinition patch for 2.6 kernel headers (attached on this bug) on my Pentium3 box. But I've failed to emerge it on my P4 and P2 boxes.

Can the problem be that I'm not using framebuffer in my kernel, considering the error?
(/usr/include/linux/fb.h:272:1: warning: this is the location of the previous definition
In file included from /var/tmp/portage/svgalib-1.9.17-r3/work/svgalib-1.9.17/src/drivers/fbdev.c:12:

make[1]: *** [drivers/fbdev.o] Error 1)

Emerged the gentoo-dev-sources-2.6.1 and applied the attacehd linux-headers-2.6
patch, and Voila! :-D

The updated patch attached above fixed the problem for me too. I'm using
2.6.1-mm4 with linux-headers-2.6.0 (bootstrapped using scripts/bootstrap-2.6.sh).
Tried it with USE=build and -build. Now all we need is a few people with
2.4 kernels who could compile this before, to try the patch.

Yes, while the attached patch actually works, it seems at first glance (and I
didn't spare it much more than that) to be a crude hack...

At least remove the childish swearing.

A problem with this fix is that it is not compatible with the 2.4.x kernel
series.  So we old-fashioned 2.4.24 folks get a broken ebuild, and we have to
comment out the patch for the build to work. See:

http://forums.gentoo.org/viewtopic.php?t=102209&highlight=kde+svgalib

for details.

What do you mean comment out the patch, this patch isn't even in the ebuild yet
and it is definitely not breaking the build on 2.4 kernels, since I added a
check in the updated patch. 


I also got confirmation from the svgalib maintainer now, that this patch is
correct.

Fixed in CVS.

You shouldn't get any issues with 2.4, but if you get the irqreturn_t error then you'll need to comment out the "2.6 compatibility" lines in  /usr/src/linux/include/linux/interrupt.h as they shouldn't be there unless you are using >= 2.4.23, which the patch now handles.
