[uml-devel] Problems applying patches to 2.6.12-rc5-mm2

[uml-devel] Problems applying patches to 2.6.12-rc5-mm2

[Anthony Brock]

In the event that something "wierd" happened to my guest binary, I've decide
to try recompiling again. However, I'm now seeing new (and old) compilation
errors with Jeff's tree. The steps were:


# tar -jxvf linux-2.6.12-rc5.tar.bz2
# cd linux-2.6.12-rc5/
# bzip2 -dc ../2.6.12-rc5-mm2.bz2 |patch -p1
# tar -xvf ../2.6.12-rc5-mm2-20050602-patches.tar
# quilt push -a
# cp -a ../.config .
# make oldconfig ARCH=um
# make ARCH=um && make modules ARCH=um

<*** OUTPUT SNIPPED ***>

  CC      arch/um/sys-i386/sigcontext.o
  AS      arch/um/sys-i386/stub.o
  CC      arch/um/sys-i386/stub_segv.o
fixdep: arch/um/sys-i386/.stub_segv.o.d: No such file or directory
make[1]: *** [arch/um/sys-i386/stub_segv.o] Error 2
make: *** [arch/um/sys-i386] Error 2
#


So, this problem is back. I then removed the 'av-skas0' patch with:


# cat patches/av-skas0|patch -p1 -R
patching file arch/um/Makefile
Hunk #1 succeeded at 64 (offset 1 line).
patching file arch/um/sys-i386/Makefile
patching file arch/um/sys-x86_64/Makefile
Hunk #1 succeeded at 32 (offset 2 lines).
#


Once more, I tried the compile:


# make ARCH=um && make modules ARCH=um

<*** OUTPUT SNIPPED ***>

  CC      kernel/futex.o
  CC      kernel/uid16.o
  CC      kernel/module.o

Ok, the other time I just looked at patch changelogs, now here's a more 
definite answer. The patch does not work because the .d file is not created.

Probably it works for you, Jeff, because you have that file as a residual from 
a previous compile...

In this section of the patch (both for i386 and x86_64), affecting 
arch/um/sys-*/Makefile, the last line:

+# _cflags works with kernel files, not with userspace ones, but c_flags does,
+# why ask why?
+$(obj)/stub_segv.o : c_flags = $(call unprofile,$(USER_CFLAGS))

should become (without the break):
+$(obj)/stub_segv.o : c_flags = -Wp,-MD,$(depfile) $(call unprofile,
$(USER_CFLAGS))

See for comparison the content of arch/um/scripts/Makefile.rules (and for the 
difference between _c_flags and c_flags, scripts/Makefile.lib).

Beyond that, for such tricks with .S files we would use a_flags (or 
_a_flags)... currently this is not needed, but just in case you need it.

Blaisor,

Thanks! Any ideas on the second compile problem? The output is:

  CC      kernel/futex.o
  CC      kernel/uid16.o
  CC      kernel/module.o
kernel/module.c: In function `module_add_modinfo_attrs':
kernel/module.c:1078: error: `modinfo_attrs' undeclared (first use in this function)
kernel/module.c:1078: error: (Each undeclared identifier is reported only once
kernel/module.c:1078: error: for each function it appears in.)
kernel/module.c: In function `module_remove_modinfo_attrs':

Leave module support out for now.  We need to do some work there still.
