Bug 40326 – GtkLauncher fails to build: Undefined references to RenderMathMLRoot, RenderMathMLSquareRoot, determineHotSpot

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Clemmitt Sigler]

Hi,

I'm trying to build WebKit/GTK on generic Linux (a Gentoo Linux installation), x86_64 platform.  Have succeeded at this many times before, but this is my first attempt in a long time and I ran into unfamiliar problems.

When linking Programs/GtkLauncher, I get these errors:

./.libs/libwebkit-1.0.so: undefined reference to `WebCore::openFile(WebCore::String const&, WebCore::FileOpenMode)'
./.libs/libwebkit-1.0.so: undefined reference to `WebCore::RenderMathMLRoot::RenderMathMLRoot(WebCore::Node*)'
./.libs/libwebkit-1.0.so: undefined reference to `WebCore::readFromFile(int, char*, int)'
./.libs/libwebkit-1.0.so: undefined reference to `WebCore::seekFile(int, long long, WebCore::FileSeekOrigin)'
./.libs/libwebkit-1.0.so: undefined reference to `WebCore::RenderMathMLSquareRoot::RenderMathMLSquareRoot(WebCore::Node*)'
./.libs/libwebkit-1.0.so: undefined reference to `WebCore::determineHotSpot(WebCore::Image*, WebCore::IntPoint const&)'

I understand the source of the RenderMathMLRoot, RenderMathMLSquareRoot and determineHotSpot problems, and will attach a patch for devs to review/approve next.

I'll also open another couple of bugs to describe the problem with WebCore::openFile, WebCore::readFromFile, and WebCore::seekFile, and remaining outdated style()->color() calls which are no longer valid (color accessors made private by rev. 59956).  The file access problem seems to be related to WebCore/platform/gtk/FileSystemGtk.cpp.  These three methods aren't defined in this file as they are in, e.g., WebCore/platform/posix/FileSystemPOSIX.cpp.  Of course, when I tried including the posix module in the build, there were namespace collisions.  It seems the fix may be to add these missing methods to WebCore/platform/gtk/FileSystemGtk.cpp???

A patch for WebCore/GNUmakefile.am follows.  HTH.

Thanks for submitting this patch. Cursor.cpp has already been added to the sources list. Nice call on the MathML sources, but make sure they added in alphabetical order.

Thanks, Martin.  Updating patch to apply to current Rev. 60887.  Attaching next.

Any chance you or someone working on Gtk could look at bug 40328 -- not sure how to attack that one besides adding methods openFile, readFromFile, seekFile to WebCore/platform/gtk/FileSystemGtk.cpp, and I'm not deft enough at GTK programming to do this correctly, I'm afraid.

Also, bug 40327 is bothersome, involving now-private RenderStyle color accessors, and caused by crufty leftover code, e.g., 'style()->color()', in a number of modules in the tree.

It seems to me that none of these problems is getting triggered by BuildBot auto-compile-tests, FWIW.  TIA.

Well, it should've been obvious to me why I'm finding build problems others haven't been seeing.  This is how I configure the GTK build:

./configure --enable-svg --enable-filters --enable-jit --enable-3D-transforms --enable-shared-workers --enable-web-sockets --enable-mathml --enable-xhtmlmp --enable-blob-slice --enable-file-reader --enable-file-writer --enable-image-resizer

IOW, I turn on everything except the stuff generally intended for a browser running on mobile equipment.

I apologize, it's my fault!  It's been a long time since I prepared a patch, and I messed up with the ChangeLog entry.  I'll attach a new patch which is correct.

Dirk (or Martin), could you please review once more?  Thanks for your patience.
