Re: [gentoo-dev] gs-sources problems: device mapper: dm.o has undeclared identifiers

[John Nilsson]

what commands did you run to compile the kernel?
Do you have the same problem with gentoo-sources?

Try this:
cd /usr/src/linux &&
cp .config .config.bak &&
make mrproper &&             #remove config related files
cp .config.bak .config &&
make clean oldconfig dep &&  #redo config, redo dep (if needed...)
make bzImage modules	     #try to compile again
