Kernel compilation ... again

[bdg1983]

I`ve gotten the new 2.4.14 kernel for my slackware 8.
I have done this a thousand way now, and I think I get the first part ok :
make mrproper
make xconfig
make dep
make bzImage ... where the problem comes.
Everything seems to go fine until I get close to the finish line. I get this message a couple of times :
/usr/src/linux-2.4.14/include/asm/checksum.h:72:30: warning: multi-line string literals are deprecated

Then this happens :
drivers/block/block.o: In function `lo_send':
drivers/block/block.o(.text+0xaeaf): undefined reference to `deactivate_page'
drivers/block/block.o(.text+0xaf3f): undefined reference to `deactivate_page'
make: *** [vmlinux] Error 1

And .. I don`t get a bzImage :mad:

There's something in the block device section that it doesn't like. I do know that loopback is broken in the 2.4.14 kernel. If you don't really need loop, try disabling it in make xconfig and try again.

I don't know if loop is causing your problem since my kernel compiles with it selected as a module. The loop module is built, but it will not load.

There was something weird with the 2.4.14 kernel, that`s for sure .. just installed 2.4.13 and it worked .. almost great.
I need loopback, but thanks for your help anyways.

You could patch the 2.4.14 kernel with the loop fix.

diff -ru linux/drivers/block/loop.c linux-patched/drivers/block/loop.c

page_cache_release(page);
}
return 0;

unlock:
UnlockPage(page);
- deactivate_page(page);
page_cache_release(page);
fail:
return -1;

Put that in a file and then

cd /usr/src/linux

patch -p1 < /path/to/loop/patch/name_of_patch

And then compile the 2.4.14 kernel.
