Bug 10247 – Unable to build webkit without SVG/XPATH

• Component: New Bugs
• Status: RESOLVED FIXED

[Dan Wood]

For Sandvox, I want/need to build without SVG support.    It's just excess baggage I don't want to bundle into the app.

I've tried build-webkit -DSVG_SUPPORT -DXPATH_SUPPORT 

and it says:unknown option: -DSVG_SUPPORT

According to http://build.webkit.org/, TOT is not building SVG-less/XPATH-less there, either.

Build Gods, please fix?

I'm pretty sure you want to run this command-line to build WebKit:

./WebKitTools/Scripts/build-webkit --no-svg --release

The "--no-svg" switch implies that the xpath support is also not built.

I'm not sure why the buildbot is failing on the no-svg build.  I tried building the no-svg build locally a few  days ago and it worked just fine.  It's almost like the buildbot gets a copy of the generated SVGElementFactory.cpp source from one of the other builds and then fails to build it.  That source file should be blank with --no-svg.

I don't think the build slave is doing anything wrong.  I get the following when trying a no-SVG build locally:

Identical errors to what the buildslave is reporting.

[Sam Weinig]

Yeah, this would be my fault.  I did not test the no-svg build before adding the -Wundef flag to the projects.  Patch forthcoming.

I'm not sure that this is the correct fix, but...
My understanding is that before SVG_SUPPORT and XPATH_SUPPORT were changed to be set by FEATURE_DEFINES, they were set to either 1 or 0. Now it seems that it is either defined or not. So my fix is to change every #if SVG_SUPPORT or #if XPATH_SUPPORT to #ifdef SVG_SUPPORT or #ifdef XPATH_SUPPORT respectively.

This patch didn't fix the build:

http://build.webkit.org/periodic-powerpc-mac-os-x-no-svg/builds/914/step-compile-release/0

It seems that there are no newlines on the touched files, and the new gcc warning flags are bailing on this.  (This seems odd, though, since I was able to build a release version of WebKit r15828 locally.  Not sure what the difference is.)

Filed Bug 10333 for this issue.
