build cause mac crash/reboot

[rustjson]

I am trying to build this project on master branch on two machine by running ./mach build --dev, both down during the compiling:

➜  servo git:(master) ./mach build --dev
   Compiling libsimpleservo v0.0.1 (/opensource/servo/ports/libsimpleservo)
   Compiling servo v0.0.1

How much RAM does your machine have?

[rustjson]

I have two machine. the current one is :

8 Go 2133 MHz LPDDR3

rust version

rustc 1.28.0 (9634041f0 2018-07-30)

[rustjson]

BTW, @jdm, sorry to ask a question not related to this thread. I wonder if I can have a small build just for the stylo components, what I wanted is just dig deeper of this component, an executable file that takes css as input and output the dom object attributes would be the prefect solution.

[jdm]

It is possible to run ./mach build -p style.

[jdm]

And it's entirely possible that building servo is causing your machine to OOM; RAM usage of the build exceeds 6GB at times.

[rustjson]

interesting, but even this cause OOM, I don't think mac got rebooted sounds normal.
Let me try to build the style only and see.

Thank you

[rustjson]

Ok, my other machine got 16G RAM

and I got this error when compile the style only

error: failed to run custom build command for `style v0.0.1 (file:///Users/jason.yang/opensource/servo/components/style)`

I try to use --cfg feature but seems I am not doing it the right way

[jdm]

You may be able to pass --features servo
