Hi Robert,<br><br>I had exactly the same problem myself (Also Ubuntu 11.10 64 bit), I can't remember if it was a problem with Boost or OIIO directly. What happened is that I used my own folder naming conventions and didn't follow the guide to the letter. Do that first to get a working build, then if you want to have your own folder names, carefully change your CMake configuration and folder names a little at a time. You'll have to rebuild the configuration and Blender/Cycles completely if you want to change the name of the build directory, my advice is to install cmake-gui, create the new build folder, open cmake-gui in both folders and copy the configuration manually.<br>
<br>Hope that helps.<br><br>Davis<br><br><div class="gmail_quote">On Sat, Oct 29, 2011 at 3:45 AM, Robert Feld <span dir="ltr"><<a href="mailto:robertmfeld@googlemail.com">robertmfeld@googlemail.com</a>></span> wrote:<br>

<br>
I failed building the cycles branch of blender under Ubuntu 11.10<br>
<br>
Following the instructions in the wiki I tried building 41354 of<br>
<a href="https://svn.blender.org/svnroot/bf-blender/branches/cycles" target="_blank">https://svn.blender.org/svnroot/bf-blender/branches/cycles</a><br>
<br>
After building boost and oiio successfully building blender failed with:<br>
<br>
blender-svn/cycles-branch/oiio/dist/linux/lib/libOpenImageIO.a(jpeg2000input.cpp.o):<br>
In function `OpenImageIO::v0::jpeg2000_input_imageio_create()':<br>
jpeg2000input.cpp:(.text+0x3d4): undefined reference to `jas_init'<br>
<br>
[many errors of the same kind following]<br>
<br>
The only thing that I noticed before was the message<br>
<br>
CMake Warning:<br>
Manually-specified variables were not used by the project:<br>
<br>
BOOST<br>
<br>
that cmake gave me. However in the output of make VERBOSE=1 it seems<br>
that it links the correct version of boost:<br>
/usr/bin/c++ -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64<br>
-D_LARGEFILE64_SOURCE -fopenmp -msse2 -msse -pipe -fPIC<br>
-funsigned-char -fno-strict-aliasing -Wall -Wno-invalid-offsetof<br>
-Wno-sign-compare -O2 -DNDEBUG -DNDEBUG -pthread<br>
CMakeFiles/blender.dir/creator.c.o CMakeFiles/blender.dir/buildinfo.c.o<br>
-o ../../bin/blender -rdynamic<br>
-L/home/sceiss/blender-svn/cycles-branch/build/../boost/lib<br>

../../lib/libbf_editor_space_console.a<br>
[--many more libs...--]<br>
../../lib/libbf_editor_space_file.a ../../../boost/lib/libboost_date_time.a<br>
<br>
I did build the cycles branch a while ago successfully with Ubuntu<br>
11.04. So could the new version (i.e. the new versions of the<br>
toolchain/libs) be the reason?<br>
<br>
Any idea what to try of how to fix the problem?<br>
<br>
Kind regards,<br>
Robert<br>
