Task failed to compile shader

[astrieanna]

I finally got servo to build today, but make check results in errors in rust-css and running the executable anyway results in immediate errors from rendergl.rs.
I'm on Fedora 18, 64-bit.

When I run make check, it ends with errors:

When I run servo, I get this output:

It seems that test codes are not updated for current Rust: for example cell module is moved from std to core.

#328 is the bug for the rust-css tests. This is a known problem, and I'm working on a fix. Once you get past the superficial things, there are some borrow checker problems that are not easy to resolve. I have added some things to Rust standard libraries in order to address this, and now that they've landed hopefully rust-css will get updated tomorrow.

I haven't seen the task failed to compile shader issue before. We'll try to reproduce.

I git pulled yesterday afternoon, and it suddenly stopped crashing. I now get a blank, bright-blue window instead.

[metajack]

Is this still happening @astrieanna ?

[astrieanna]

@metajack No; as I commented above a month ago, it stopped crashing after I pulled again. (I haven't tried it since then.)

[metajack]

I meant the bright blue window, which is not the expected behavior. Perhaps it was just the color swap combined with missing fonts. The color swap should now be fixed on master and installing msttcorefonts should solve the missing text.

I'll close this bug since there are already issues for those other things.
