Compile Blender+Yafaray for Turion64x2

hello! long time no post..

i encountered a problem recently on compiling blender+yafaray using the sevenblend script. It gives me this error:

Compiling ==> 'SND_DummyDevice.cpp'
cc1plus: warning: command line option "-Wdeclaration-after-statement" is valid for C/ObjC but not for C++

By the way, am using a 64-bit ubuntu 9.04. I'm using the 2.6.30 kernel optimized for my processor (turion64x2).

Thanks to jensverwiebe for helping me out..

First, am using the WITH_OPTIM option, so i needed to change the user-config.py. It is supposed to compile an optimized blender+yafaray for your processor. so instead of simply typing ./sevenblend, i type this:

./sevenblend WITH_OPTIM

Go to the user-config directory, and rename user-config.py to user-config.py.bak for backup purposes.

Rename AMD64_user-config.py to user-config.py. This user configuration file is for a 64-bit AMD processor. If you'll be compiling an optimized build of blender+yafaray (using ./sevenblend WITH_OPTIM command), you may want to check out your processor and choose which config file to use. If you have a Core 2 processor, rename CORE2DUO_user-config.py into user-config.py.

Now we'll be editing our user-config.py (formerly AMD64_user-config.py). The error i posted above was due to the fact that my processor need a different flag, it should use k8 rather than nocona. My processor is part of the k8 processor family. Edit this line:

CFLAGS="-march=nocona -O2 -pipe"

and change it into

CFLAGS="-march=k8 -O2 -pipe"

Save the file.

Now, we'll be editing another file named linux2-config.py. It is located at .sources/blender/config. This will only be present if you've already attempted to use the sevenblend script. It will download the source code of blender and everything you need to compile. Look for the following lines:

REL_CFLAGS = ['-O2']
REL_CCFLAGS = ['-O2']

and change them into

REL_CFLAGS = ['-O2','-march=k8']
REL_CCFLAGS = ['-O2','-march=k8']

Save the file and then compile. All should be well after doing this.. :)
