Last week I switched the iOS and Mac builds to use WEBCORE_EXPORT instead of
WebCore.exp.in. This should make maintenance easier, but there are a few
quirks everybody should be aware of:
1) Do not use WEBCORE_EXPORT before a function defined in a header. This will
cause check-for-weak-vtables-and-externals to fail sometimes. See
http://trac.webkit.org/changeset/179974/trunk/Source/WebCore/dom/Range.h
<http://trac.webkit.org/changeset/179974/trunk/Source/WebCore/dom/Range.h> for
an example fix.
2) If you need to export the vtable of a class, put WEBCORE_EXPORT between
“class" and the class name, but not before method and member variable
declarations. Otherwise Visual Studio will not compile successfully after we
get rid of WebKitExports.def.in. See
http://trac.webkit.org/changeset/180301/trunk/Source/WebCore/bridge/runtime_method.h
<http://trac.webkit.org/changeset/180301/trunk/Source/WebCore/bridge/runtime_method.h>
for an example fix.
