I tried to emerge nvidia-drivers after updating gentoo-sources to 3.17.2. I attache my build.log. Here is my portage info:

Comment 1 Jeroen Roovers gentoo-dev 2014-11-03 11:32:25 UTC
The bit of code that fails seems to be:

#if !defined(NV_VMWARE) && !defined(NVCPU_FAMILY_ARM) && !defined(NVCPU_PPC64LE)

You're not in one of those categories.

#if !defined(NV_SET_MEMORY_UC_PRESENT) && !defined(NV_SET_PAGES_UC_PRESENT) && \
  !defined(NV_CHANGE_PAGE_ATTR_PRESENT)

So one of these must be failing to get this error printed:

#error "This driver requires the ability to change memory types!"
#endif
#endif

Correction: /all/ of these must be failing.
Comment 3 Nikolaos Chatzidakis 2014-11-03 11:35:10 UTC
I look into this issue several days now but can't think of any solution... I clean-built my kernel again, deleted my /var/tmp/portage and my nvidia installers in /usr/portage/distfiles but none of these worked... Do you want me to test here something for you? Thank you for your time and effort working on this issue. :)
Comment 4 Jeroen Roovers gentoo-dev 2014-11-03 12:05:34 UTC
Do you have KBUILD_OUTPUT set in your environment? I.e. please attach the environment file mentioned in the build log.

Comment 6 Micke Eriksson 2014-11-04 01:11:22 UTC
I have the same problem but on 340.46, tried several older kernels...same problem.

Comment 13 Nikolaos Chatzidakis 2014-11-06 13:36:12 UTC
I tried reverting all of the updates I did before this bug occurred but the problem persists. I rebuilt my @system, rebuilt gcc, tried some patches I found on google for kernel sources 3.18 (beta) but none of them worked... I honestly don't know what may be the problem, other than incompatibility with the new kernel sources...

Yes, I know. I put the ebuild there. But I don't have this issue, so I can't fix it until I can figure out what is going wrong and reproduce it locally.
Comment 22 Jeroen Roovers gentoo-dev 2014-11-06 23:26:07 UTC
Does it help to set KBUILD_OUTPUT (to an empty value)?
Comment 23 Sven Eden 2014-11-07 08:24:03 UTC
Please do an

ebuild ebuild /usr/portage/x11-drivers/nvidia-drivers/nvidia-drivers-343.22-r2.ebuild compile

Then please post the output of the conftest. The result is here:

<PORTAGE_TMPDIR>/portage/x11-drivers/nvidia-drivers-343.22-r2/work/kernel/conftest/functions.h

If all of the above are #undef, then it is a problem with your kernel configuration.

For reference, here is the output on my system, where the this driver compiles fine with a 3.16.7 kernel installed:

-----
 # grep -P "(SET_MEMORY|SET_PAGES|CHANGE_PAGE)" kernel/conftest/functions.h
#define NV_SET_PAGES_UC_PRESENT
#define NV_SET_MEMORY_UC_PRESENT
#define NV_SET_MEMORY_ARRAY_UC_PRESENT
#undef NV_CHANGE_PAGE_ATTR_PRESENT
-----

These are decided by three little test programs which simply call the appropriate functions. What is a bit weird is, that the text succeeds if the program can not be compiled (too few arguments).

btw: Which linux-headers do you have installed?

After it breaks, cd into the build dir and execute the make command which failed.

Comment 35 Sven Eden 2014-11-07 14:54:33 UTC
Okay, this seems to have something to do with anything but portage, gcc or the nvidia drivers.

Look at this from Justins conftest log:
--------

                set_pages_uc();

--------

The test program on top is wrong. So the conftest looks whether it can be compiled anyway. If it can, it means that the function is not declared in the includes, and then the #undef is issued.

As you can see above, the compilation fails (too few arguments) as it should be, but the #undef is nevertheless issued.

Could it be that you have /bin/sh linked to something different than /bin/bash? dash or zsh maybe? Because the lines responsible for this are:

--------
            echo "$CONFTEST_PREAMBLE
            #include <asm/cacheflush.h>
            void conftest_set_pages_uc(void) {
                set_pages_uc();
            }" > conftest$$.c

            $CC $CFLAGS -c conftest$$.c > /dev/null 2>&1
            rm -f conftest$$.c

            if [ -f conftest$$.o ]; then
                rm -f conftest$$.o
                echo "#undef NV_SET_PAGES_UC_PRESENT" | append_conftest "functions"
                return
            else
                echo "#define NV_SET_PAGES_UC_PRESENT" | append_conftest "functions"
                return
            fi
---------
So as you can see, if the compilation fails, like logged above, [ -f conftest$$.o ] should fail, too.

Because it is still around. I had this, too, and just deleted the old (already unmerged) orphaned directories of previous kernels.

However, user tranquilcool  reports to have solved the issue by simply deactivating ccache here:

So, it finally worked here. I don't know what exactly solved the problem, but these are the steps i followed:

* Removed all /lib/modules/x.y.z/ directories of older kernels, and kept only the modules of 3.17.2
* Unemerged nvidia-drivers
* Unemerged all gentoo-sources and deleted everything in /usr/src
* Deleted /var/tmp/portage/*
* Emerged latest gentoo-sources again (3.17.2), used my old .config and built the kernel as usual
* Emerged nvidia-drivers WITHOUT ccache, and this time it worked.

Don't know what was the specific problem, but doing the about, managed to emerge nvidia-drivers but without ccache.
Comment 40 Micke Eriksson 2014-11-07 21:11:53 UTC
Disabling ccache works!

FEATURES="-ccache"
Comment 41 Nils Kneuper 2014-11-08 10:47:35 UTC
Same for me. Had the issues and setting FEATURES="-ccache" fixes the problem. It was not enough to completely empty the ccache cache.
Comment 42 Adam Stylinski 2014-11-08 18:17:00 UTC
Ahh, this possibly explains a lot of the weird issues I've been having with VDPAU related crashes and kernel module rebuilds that resulted in supposedly missing symbols, despite being built against the correct sources.  I feel dumb now :-/.
Comment 43 Nikolaos Chatzidakis 2014-11-09 11:36:51 UTC
For me though (and others as I see) disabling ccache didn't solve the issue right away. I tried it many times before and it didn't work, until i did all the steps I mentioned above... Who knows...

The ebuilds already try to disable ccache, but apparently this doesn't work as advertised in the manual:

       CCACHE_DISABLE
           If you set the environment variable CCACHE_DISABLE then ccache will just
           call the real compiler, bypassing the cache completely.
