Following the Chromium Trac page (http://trac.webkit.org/wiki/Chromium), the issues arised running `update-webkit` (using yesterday's nightly build): 1.) WebKit/chromium/DEPS misses many dependencies. In particular: libwebp zlib modp_b64 libevent harfbuzz iccjpeg libjpeg libpng libxml libxslt libwebp npapi sqlite mesa yasm openmax grit I fixed this issue by manually adding these to DEPS. 2.) The subprocess call on WebKit/chromium/tools/gyp/pylib/gyp/input.py:639 is broken. ``contents[1]`` starts with "../tools/" but the script is called from WebKit/chromium/ so the "../" should not be there.
Looks like this was a transient issues with Chromium: I have build chromium using WebKit for the past months without issues. If it is still happening, please reopen this bug and blame me!
