For those who don't know ANGLE project is not a microsoft one which apparently is first in result when I type it on duckduckgo but google founded Almost Native Graphics Layer Engine that is part of, to name a few: Chrome, Firefox or Qt.
It's great piece of software I always wanted to dig into because it's behind webgl engine of chromium project.
I had some inconsistency in great getting started document so I would like to provide step by step guide how to simply run
I assume you got at least git installed. I don't know if I got any more dependencies.
Let's start by downloading 2 repositories next to each other:
The actual angle project repo:
git clone https://chromium.googlesource.com/angle/angle
And build tools:
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
So we want to make those tools executable from angle directory so we will either do it once by executing:
export PATH=`pwd`/depot_tools:"$PATH" or add path of
depot_tools directory to
~/.bashrc if you want permanent change.
Next commands we will execute in
angle directory location. So simply
After that on mac os x or linux we want to change our default renderer therefore edit
with your favourite renderer and change:
# define ANGLE_DEFAULT_D3D11 1 to
and then simply run some commands to sync our project using this magic:
git checkout master
The last thing we need to do is setup gyp generators:
`GYP_GENERATORS=ninja gclient runhooks`
and at the very end after making path `mkdir -p out/Debug` compile it:
`ninja -j 10 -k1 -C out/Debug`
if you find out error that is something like this:
ninja: error: loading 'build.ninja': No such file or directory
just repeat `GYP_GENERATORS=ninja gclient runhooks` and then `ninja -j 10 -k1 -C out/Debug` part.
if everything is ok you will see something like this
ninja: Entering directory 'out/Debug'
[147/1307] CXX obj/src/compiler/translator/translator.TranslatorGLSL.o
and after it finished compilation you can see triangle by executing
Here it is:
I hope you managed to do it.
