Bug 443186 – =sys-kernel/hardened-sources-3.5.4-r1 doesn't build with uclibc

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description Alex Brandt (RETIRED) 2012-11-15 02:34:45 UTC]

When building the hardened kernel on a uclibc system (experimental hardened profile and stages) the build results in a symbol collision error.

Reproducible: Always

Steps to Reproduce:
1. Install uclibc stage3 on x86
2. Install hardened-sources and compile them
3. Build errors out
Actual Results:  
mint linux # make -j2 && make -j2 modules_install
make[1]: Nothing to be done for `all'.
make[1]: Nothing to be done for `relocs'.
  CHK     include/linux/version.h
  CHK     include/generated/utsrelease.h
  CALL    scripts/checksyscalls.sh
  CHK     include/generated/compile.h
  CHK     kernel/config_data.h
make[3]: `arch/x86/realmode/rm/realmode.bin' is up to date.
  CHK     include/linux/version.h
make[2]: Nothing to be done for `all'.
make[2]: Nothing to be done for `relocs'.
  HOSTCC  Documentation/accounting/getdelays
Documentation/accounting/getdelays.c:54:7: error: 'stime' redeclared as different kind of symbol
/usr/include/time.h:308:12: note: previous declaration of 'stime' was here
make[2]: *** [Documentation/accounting/getdelays] Error 1
make[1]: *** [Documentation/accounting] Error 2
make[1]: *** Waiting for unfinished jobs....
make: *** [vmlinux] Error 2


Expected Results:  
Successful kernel build.

Configuration for the kernel being built (shouldn't make much of an impact) is attached in case it's useful.  Let me know what else I can provide to help track this one down.

Forgot to mention versions:

* sys-kernel/hardened-sources-3.5.4-r1
* sys-libs/uclibc-0.9.33.2-r2

Let me know if there is anything else I can provide to help track this down.

Okay hit it.

Okay I got this fixed.  In a minute I'll be emailing it to lkml and I'll attach it here for further testing.

[Comment 6 Anthony Basile 2012-11-24 17:07:33 UTC]

This is not hardened specific, so I'm dropping hardened@ and sending it kernel@'s way.

@Alex.  Do you mind testing the patch.  Just apply it to the kernel tree, whether dirty or not, and continue building with `make -j2`.
