           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org

I tried to save compilation time by disabling as many optional things as possible. One of them being XSLT as per ./configure --help. As XSLT is optional, I didn't install it.

But then WebKit doesn't build:
  CXX    DerivedSources/WebCore/libWebCore_la-JSHTMLAllCollection.lo
  CXX    DerivedSources/WebCore/libWebCore_la-JSHTMLAnchorElement.lo
In file included from ./Source/WebCore/xml/XSLTProcessor.h:29:0,
                 from DerivedSources/WebCore/JSXSLTProcessor.h:27,
                 from DerivedSources/WebCore/JSDOMWindow.cpp:590:
./Source/WebCore/xml/XSLStyleSheet.h:33:31: fatal error: libxslt/transform.h: No such file or directory
compilation terminated.
make[1]: *** [DerivedSources/WebCore/libWebCore_la-JSDOMWindow.lo] Error 1
make[1]: *** Waiting for unfinished jobs....
  CXX    DerivedSources/WebCore/libWebCore_la-JSHTMLAppletElement.lo
make[1]: Leaving directory `/tmp/WebKit'
make: *** [all] Error 2


When XSLT is installed, but when WebKit is configured with --disable-xslt:

I configured like this:
$ head config.log 
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by WebKitGTK configure 2.1.0, which was
generated by GNU Autoconf 2.68.  Invocation command line was

  $ ./configure --disable-xslt


One solution is to fix the build system to not depend on XSLT stuff, i.e. it may be possible to not include the objects mentioned in libWebCore.
But I know next to nothing about it so it is way easier for me to depend on XSLT. Also, nothing ever uses ENABLE_XSLT.
So I wrote the patch attached.
