Windows

Linux

Static link environment

A static link environment is used to create binaries for releases. Most libraries that LuxCore depends on are embedded into the LuxCore executables.

First Run

On a recent Ubuntu (e.g. 19.10), you can compile LuxCore with the following commands:

sudo apt install git
git clone https://github.com/LuxCoreRender/LinuxCompile.git
cd LinuxCompile
./first_run.sh

To test LuxCoreUI, you can now start it:

cd target-64-sse2/LuxCore-opencl/
./luxcoreui ./scenes/cornell/cornell.cfg

Updating

To update to the latest sources, use standard git commands:

cd LuxCore-opencl
git pull
# Go back to LinuxCompile folder and compile
cd ..
./build-64-sse2 LuxCore-opencl 5

Recompiling

In case you update the LuxCore repository (by using git pull), re-run the last stage (5) of the build script:

./build-64-sse2 LuxCore-opencl 5

In case you edit any source files and want to recompile quickly, go to the LuxCore sources directory and run make:

cd LuxCore-opencl
make -j8

(-j<n> specifies number of threads for the compilation process)

The compiled binaries are in LuxCore-opencl/bin/, the compiled libraries (e.g. pyluxcore.so) are in LuxCore-opencl/lib/

Ubuntu 14.04 LTS (Dynamic linking)

Dynamic link builds are only used for developing/debugging, not for release builds.

Ubuntu 16.04 LTS (Dynamic linking)

Dynamic link builds are only used for developing/debugging, not for release builds.

# Install deps

# Install Pillow
sudo pip3 install pillow

# To have Python v3.x in pyluxcore.so
sudo rm /usr/lib/x86_64-linux-gnu/libboost_python.so
sudo ln -s /usr/lib/x86_64-linux-gnu/libboost_python-py35.so /usr/lib/x86_64-linux-gnu/libboost_python.so

# Compile LuxCore
git clone https://github.com/LuxCoreRender/LuxCore.git
cd LuxCore

make -j 8

NOTE: Default Boost version in Ubuntu 16.04LTS is v1.58. Any serialization related feature will not work with standard version v1.56.

MacOs 10.13 +

Install build environment

Install latest Xcode and Command Line Tools for your OS version.

Install Homebrew

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Install brew stuff and python3

brew install pyenv cmake bison gnu-sed gnu-tar xz libtool autoconf automake ispc
PATH="/usr/local/opt/gnu-sed/libexec/gnubin:$PATH"
PATH="/usr/local/opt/gnu-tar/libexec/gnubin:$PATH"
pyenv init
eval "$(pyenv init -)”
env PYTHON_CONFIGURE_OPTS="--enable-framework" pyenv install 3.7.4
pyenv global 3.7.4
pip install numpy
pip install pillow
pip install pyside2

For CUDA builds on MacOS 10.13 only install cuda toolkit.

https://developer.nvidia.com/cuda-10.1-download-archive-base?target_os=MacOSX&target_arch=x86_64&target_version=1013

Compile Dependencies

pyenv shell 3.7.4

git clone https://github.com/LuxCoreRender/MacOSCompileDeps.git
cd MacOSCompileDeps
./cut_deps_release

This will leave you with a MacDistFiles.tar.gz .

Compile LuxCore

git clone https://github.com/LuxCoreRender/LuxCore.git
cd LuxCore

Copy MacDistFiles.tar.gz to LuxCore root and unpack. Just double-click. or

tar xzf MacDistFiles.tar.gz

Now do

cmake

export PATH="/usr/local/opt/bison/bin:/usr/local/bin:$PATH"
DEPS_SOURCE=`pwd`/macos
mkdir build
cd  build
cmake -DOSX_DEPENDENCY_ROOT=$DEPS_SOURCE -DCMAKE_BUILD_TYPE=Release ..
make

use

-DLUXRAYS_DISABLE_OPENCL=1

for non OpenCL build

and

-DLUXRAYS_ENABLE_OPENCL=1 -DLUXRAYS_ENABLE_CUDA=1

for CUDA builds.( 10.13 HighSierra only )

Xcode

export PATH="/usr/local/opt/bison/bin:/usr/local/bin:$PATH"
DEPS_SOURCE=`pwd`/macos
mkdir build
cd  build
cmake -G Xcode -DOSX_DEPENDENCY_ROOT=$DEPS_SOURCE -DCMAKE_BUILD_TYPE=Release ..

use

-DLUXRAYS_DISABLE_OPENCL=1

for non OpenCL build

and

-DLUXRAYS_ENABLE_OPENCL=1 -DLUXRAYS_ENABLE_CUDA=1

for CUDA builds.( 10.13 HighSierra only )

Open Xcode project and compile.

Make bundle

run

./scripts/macos/pack_lux_osx.sh

or for XCode build

./scripts/macos/pack_lux_osx_xcode.sh

from LuxCore root.

This should end up with a distributable .dmg.

Have fun and good luck.

Contributing

If you want to contribute to LuxCore development or just submit a quick patch, the easiest way to start is to fork the repository on github.
You can then edit your fork, commit your changes and send us a pull request.
If you continue to contribute, we will eventually give you direct access to the repositories.
