=== 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:

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

To test LuxCoreUI, you can now start it:

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

==== Updating ====

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

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

==== Recompiling ====

In case you update the LuxCore repository (by using git pull), re-run the last stage (5) of the build script:
<pre>
./build-64-sse2 LuxCore-opencl 5
</pre>

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

<pre>
cd LuxCore-opencl
make -j8
</pre>
(-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.

=== Compile Dependencies ===

<pre>pyenv shell 3.7.4

git clone https://github.com/LuxCoreRender/MacOSCompileDeps.git
cd MacOSCompileDeps
./cut_deps_release</pre>
This will leave you with a MacDistFiles.tar.gz .

=== Compile LuxCore ===

<pre>git clone https://github.com/LuxCoreRender/LuxCore.git
cd LuxCore</pre>

Copy MacDistFiles.tar.gz to LuxCore root and unpack. Just double-click. or 
<pre>tar xzf MacDistFiles.tar.gz</pre>

Now do
==== cmake ====
<pre>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</pre>

==== Xcode ====
<pre>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 ..
</pre>

Open Xcode project and compile.

=== Make bundle ===
edit scripts/macos/codesign.sh to match your certificate ( something like A1CD139B9FD66DE9D474D420C1899EA96A622B9A )

run 
<pre>./scripts/macos/pack_lux_osx.sh</pre>
or for XCode build
<pre>./scripts/macos/pack_lux_osx_xcode.sh</pre>
from LuxCore root.

This should end up with a distributable .dmg.

Have fun and good luck.
