Installing Blender on CentOS 5 x86 64

From BeSTGRID

Jump to: navigation, search

Installing Blender on CentOS 5 has been much simpler then on CentOS 4 - all of the dependencies are available as RPMs, in either CentOS core distribution or in EPEL.

This page is specifically about installing Blender on CentOS 5 x86_64 - but the same would apply to CentOS 5 i386 (minus the changes related to the lib64 directory name).

Note: The original description - to build Blender from source and link against CentOS 5 + EPEL packages - did not work. Blender kept randomly segfaulting.

Instead:

  • download the Blender packages (for glibc236 python 2.5)
  • install all the dependencies listed below
  • build python 2.5.4 from source with shared libraries enabled: 
./configure --enable-shared --prefix=/opt/shared/python/2.5.4-x86_64
make
make install
  • wrap blender to set: 
export PYTHONHOME=/opt/shared/python/2.5.4-x86_64
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PYTHONHOME/lib


Contents

[edit] Prerequisites

  • Enable EPEL
    rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/x86_64/epel-release-5-3.noarch.rpm
  • Install dependencies
    yum install yasm cmake SDL-devel OpenEXR-devel libtiff-devel python-devel openal openal-devel freetype-devel libjpeg-devel libpng-devel giflib-devel libXmu-devel libXi-devel


[edit] Download source

Download blender-2.49a.tar.gz from http://download.blender.org/source/ and extract it into a temporary directory.

[edit] Modify makefiles

  • Edit source/Makefile to use /lib64/libname.so instead of /lib/libname.a for libjpeg.a, libopenal.a and libfreetype.a

< COMLIB += $(NAN_JPEG)/lib/libjpeg.a

> COMLIB += $(NAN_JPEG)/lib64/libjpeg.so

<             COMLIB += $(NAN_FREETYPE)/lib/libfreetype.a
---
>             COMLIB += $(NAN_FREETYPE)/lib64/libfreetype.so

<         NAN_SND_LIBS += $(NAN_OPENAL)/lib/libopenal.a
---
>         NAN_SND_LIBS += $(NAN_OPENAL)/lib64/libopenal.so
  • Make a similar change to the definition of NAN_OPENEXR_LIBS, NAN_PYTHON_LIB, and NAN_FFMPEGLIBS in source/nan_definitions.mk

<     export NAN_PYTHON_LIB ?= $(NAN_PYTHON)/lib/python$(NAN_PYTHON_VERSION)/config/libpython$(NAN_PYTHON_VERSION).a
---
>     export NAN_PYTHON_LIB ?= $(NAN_PYTHON)/lib64/python$(NAN_PYTHON_VERSION)/config/libpython$(NAN_PYTHON_VERSION).a
377c377
<     export NAN_FFMPEGLIBS ?= -L$(NAN_FFMPEG)/lib -lavformat -lavcodec -lavutil -lswscale -lavdevice -ldts -lz
---
>     export NAN_FFMPEGLIBS ?= -L$(NAN_FFMPEG)/lib64 -lavformat -lavcodec -lavutil -lswscale -lavdevice -ldts -lz
384c384
<       export NAN_OPENEXR_LIBS ?= $(addprefix ${NAN_OPENEXR}/lib/lib,$(addsuffix .a,$(shell pkg-config --libs-only-l OpenEXR | sed -s "s/-l//g" )))
---
>       export NAN_OPENEXR_LIBS ?= $(addprefix ${NAN_OPENEXR}/lib64/lib,$(addsuffix .so,$(shell pkg-config --libs-only-l OpenEXR | sed -s "s/-l//g" )))


[edit] Compile

  • Override the Python version in the environment and run make: 
NAN_PYTHON_VERSION=2.4 make

[edit] Install

  • Just copy the obj/*/bin/blender executable into the desired target location: 
cp obj/*/bin/blender /opt/shared/blender/2.49a/bin/blender
