Won't compile: Makefile:442: *** mixed implicit and normal rules. Stop. about openbmc

[tfangit]

Just based on "Makefile:442: *** mixed implicit and normal rules. Stop.", I suspect that the make from CentOS 7 is new, and it does not like the Makefile from linux-2.6.28.9.

In order to fix it, we will need to separate rules in Makefile:442. Meanwhile, if you can get an old make or CentOS 6.X, that would help to avoid this issue.

Same error occurs on CentOS 6.6

These are the exact steps I did, starting with a clean CentOS install:

yum install gawk make wget tar bzip2 gzip python unzip perl patch diffutils diffstat git cpp gcc gcc-c++ glibc-devel texinfo chrpath SDL-devel xterm
wget http://downloads.yoctoproject.org/releases/yocto/yocto-1.7.1/buildtools/poky-glibc-x86_64-buildtools-tarball-core2-64-buildtools-nativesdk-standalone-1.7.1.sh
bash poky-glibc-x86_64-buildtools-tarball-core2-64-buildtools-nativesdk-standalone-1.7.1.sh
adduser brak
su brak
cd ~
git clone -b daisy https://git.yoctoproject.org/git/poky
cd poky
git clone -b daisy https://github.com/openembedded/meta-openembedded.git
git clone https://github.com/facebook/openbmc.git meta-openbmc
cd ~/poky/; source /opt/poky/1.7.1/environment-setup-x86_64-pokysdk-linux; export TEMPLATECONF=meta-openbmc/meta-facebook/meta-wedge/conf; source oe-init-build-env
bitbake wedge-image

I also found a build issue for compiling the images for Yosemite:

This is due to perl 5.22 does not handle the statement, defined(@Val):
Can't use 'defined(@array)' (Maybe you should just omit the defined()?) at timeconst.pl line 373.

This can be fixed by modifying defined(@Val) as !@Val.
