1 INSTALL DEPENDENCIES
First create a folder where to work.
mkdir ~/dev
sudo apt-get install build-essential mercurial subversion cmake flex bison
sudo apt-get install libbz2-dev zlib1g-dev
Follow Dougal's tutorial to download and install python3.2 and boost (chapters 2 and 5: http://www.luxrender.net/forum/viewtopic.php?f=22&t=5750)
2 DOWNLOAD AND INSTALL FREEGLUT
Download the latest stable freeglut release from here http://freeglut.sourceforge.net/index.php#download
Unpack the archive into ~/dev and rename the unpacked folder into freeglut Open a Terminal.
cd ~/dev/freeglut
./configure
make all
sudo make install
3 DOWNLOAD AND BUILD OPENCL SDK
Download AMD APP SKD from amd's site. http://developer.amd.com/sdks/AMDAPPSDK/downloads/Pages/default.aspx
Download Linux32 if you want to build 32bit or linux64 for 64bit version.
Unpack the archive. It should contain another targz archive. Unpack it into ~/dev and rename the unpacked folder to appsdk.
Open a Terminal.
cd ~/dev/appsdk
make
if make returns an error code, just retry.
4 DOWNLOAD AND COMPILE LUXRAYS SOURCE
Open your browser to http://src.luxrender.net/ Click on the gz button of luxrays to download.
Unpack the gz archive into ~/dev and rename the unpacked folder to luxrays Now we'll configure the make configuration files for luxrays. Open ~/dev/luxrays folder and open Configuration.cmake
In lines 56-58 you have to define the paths to boost, opencl and freeglut. This is what it should be like after edited:
Open a Terminal.
cd ~/dev/luxrays
cmake .
If cmake doesn't return any error code skip "Fixing cmake errors" and go to "Making"
Fixing cmake errors
cmake will return an error. Now we'll fix the error by editing CMakeCache.txt file. This could be different for every user.
Ctrl+F to open Find panel. Look for 'boost'.
Change Boost_INCLUDE_DIR:PATH to /usr/include/boost (only edit the part after '=', not the entire line).
Change Boost_LIBRARY_DIRS:FILEPATH to /usr/lib
Now open Find panel to look for 'opencl'. Make the three lines be something like this:
Notice that in the example the linked libOpenCL.so is the x86 version. Some users may need to use the x64 version.
Save and close.
Open Terminal
cd ~/dev/luxrays
cmake .
now you shouldn't get any error. If an error occurs, read carefully the console output and try to fix it in CMakeCache.txt like we have done for boost and opencl.
Making
make
Luxrays is built! You'll find the executables in ~/dev/luxrays/bin directory.
