2.6.32-rc5-git3 compile problems

2.6.32-rc5-git3 compile problems

[Alex]

Hi,

I receive the following error when using defconfig on 2.6.32-rc5-git3:

  CC      kernel/seccomp.o
  CC      kernel/rcutree.o
kernel/rcutree.c: In function `__rcu_init':
kernel/rcutree.h:296: sorry, unimplemented: inlining failed in call to
'rcu_bootup_announce': function body not available
kernel/rcutree.c:1702: sorry, unimplemented: called from here
make[1]: *** [kernel/rcutree.o] Error 1
make: *** [kernel] Error 2

Is this something I'm doing wrong? I'm actually trying to compile
2.6.31.5 with the default config, and it too fails, for another
reason. I'm having difficulty compiling 2.6.31 and 2.6.31.5 on x86
with gcc-3.4.4 and binutils-2.20.51.0.2. I'm also using glibc-2.3.6.

I'd sure appreciate any pointers on how to troubleshoot this.

Thanks,
Alex

Given that this is anything but performance-critical, could we instead
remove the "inline" above and on the forward declaration, possibly
also marking as __init?

Or am I misunderstanding the problem?

Re: 2.6.32-rc5-git3 compile problems

[Alex]

Hi,

> Try this patch, thanks.

I believe your patch to rcutree_plugin.h and rcutree.h worked, but I'm
now still having difficulty with con_init():

  GEN     .version
  CHK     include/linux/compile.h
  UPD     include/linux/compile.h
  CC      init/version.o
  LD      init/built-in.o
  LD      .tmp_vmlinux1
drivers/built-in.o: In function `con_init':
vt.c:(.init.text+0x3a6b): undefined reference to `.L1626'
make: *** [.tmp_vmlinux1] Error 1

Is this also a bug, or am I doing something wrong? Is there something
I can do to produce more debugging info, or troubleshoot it further?

This is 2.6.32-rc5-git3, gcc-3.4.4, glibc-2.3.6, and binutils-2.20.51.0.2.

Thanks,
Alex
