Pre-Compiled Binaries
|
|
=====================
|
|
|
|
* Download the precompiled binaries from :sfdownloads:`Javascript`, or the development versions from the buildbot server at :sfnightly:`Javascript`
|
|
|
|
* Load your js file into your website, following the structure of `the example here <https://github.com/CoolProp/CoolProp/blob/master/wrappers/Javascript/index.html>`_, which is also included at the above download link

User-Compiled Binaries
|
|
======================

|
|
Linux
|
|
-----
|
|
We are following the instructions from `emscripten.org <http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html>`_ - download the portable emscripten SDK `emsdk` for linux.
|
|
|
|
1. First download node.js, clang++ and llvm using::
|
|
|
|
sudo apt-get install nodejs clang++ llvm
|
|
|
|
2. Expand the SDK zip file linked above
|
|
|
|
3. At the console in the folder that contains the file emsdk run the commands::
|
|
|
|
emsdk update # This will fetch the list of things to download
|
|
|
|
emsdk install latest # This will download and install the full toolchain
|
|
|
|
4. Go enjoy a nice walk or a cup of coffee - it will be a while
|
|
|
|
5. Activate the SDK just compiled::
|
|
|
|
emsdk activate latest # This will make the file ~/.emscripten with the paths to most of the binaries compiled in SDK
|
|
|
|
6. Modify the file ``~/.emscripten`` to make NODE_JS path equal to ``which nodejs`` if it doesn't already
|
|
|
|
7. Make an environmental variable (in ~/.profile) ``export EMSCRIPTEN=/path/to/emsdk`` that points to the folder that contains ``emc++``, ``emcc``, etc.
|
|
|
|
8. Check out coolprop::
|
|
|
|
git clone https://github.com/CoolProp/CoolProp --recursive
|
|
|
|
9. Folder creating::
|
|
|
|
mkdir -p build && cd build
|
|
|
|
10. Build the Javascript module::
|
|
|
|
cmake .. -DCOOLPROP_JAVASCRIPT_MODULE=ON -DCMAKE_TOOLCHAIN_FILE=${EMSCRIPTEN}/cmake/Platform/Emscripten.cmake
|
|
|
|
Windows
|
|
-------
|
|
1. Download the `EMSDK installer <http://kripken.github.io/emscripten-site/docs/getting_started/downloads.html>`_, run the web download installer, that will install everything, and get you ready.
|
|
|
|
2. In the ``%HOME%/.emscripten`` file, make sure that there is only one entry for NODE_JS and it points to the right place. Mine looks like::
|
|
|
|
import os
|
|
SPIDERMONKEY_ENGINE = ''
|
|
LLVM_ROOT='C:/Program Files/Emscripten/clang/e1.21.0_64bit'
|
|
NODE_JS='C:/Program Files/Emscripten/node/0.10.17_64bit/node.exe'
|
|
PYTHON='C:/Program Files/Emscripten/python/2.7.5.3_64bit/python.exe'
|
|
EMSDK_GIT='C:/Program Files/Emscripten/git/1.8.3'
|
|
EMSCRIPTEN_ROOT='C:/Program Files/Emscripten/emscripten/1.21.0'
|
|
V8_ENGINE = ''
|
|
TEMP_DIR = 'c:/users/belli/appdata/local/temp'
|
|
COMPILER_ENGINE = NODE_JS
|
|
JS_ENGINES = [NODE_JS]
|
|
|
|
3. Open an Emscripten command Prompt (Start->Emscripten->Emscripten command Prompt)
|
|
|
|
4. Make an environmental variable ``EMSCRIPTEN`` that points to the folder that contains ``emc++``, ``emcc``, etc.
|
|
|
|
5. Navigate to the root of the source
|
|
|
|
6. Build the build folder::
|
|
|
|
mkdir build && cd build
|
|
|
|
7. Build the Javascript module::
|
|
|
|
cmake ../.. -DCOOLPROP_JAVASCRIPT_MODULE=ON -DCMAKE_TOOLCHAIN_FILE=%EMSCRIPTEN%/cmake/Platform/Emscripten.cmake
