Bug 45874 – introspection does not build with g-i 0.9.5

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

[Götz Waschk]

This is with webkit gtk 1.2.4 on Mandriva Linux with gobject-introspection 0.9.5:

  GEN    WebKit-1.0.gir

Confirming the same behaviour on Ubuntu 11.04

The current JSCore is:

<?xml version="1.0"?>
<repository version="1.1"
            xmlns="http://www.gtk.org/introspection/core/1.0"
            xmlns:c="http://www.gtk.org/introspection/c/1.0">
  <namespace name="JSCore" version="1.0" shared-library="webkit-1.0">
    <alias name="GlobalContextRef"
           target="none"
           c:type="JSGlobalContextRef"/>
    <alias name="ObjectRef" target="none" c:type="JSObjectRef"/>
    <function name="EvaluateScript" c:identifier="JSEvaluateScript">
      <return-value transfer-ownership="none">
        <type name="none" c:type="void"/>
      </return-value>
      <parameters>
      </parameters>
    </function>
  </namespace>
</repository>

Debugging shows it is the <alias> tags that is causing the problem.  I changed them to the following:

<alias name="GlobalContextRef" c:type="JSGlobalContextRef">
  <type name="opaque" c:type="void*"/>
</alias>
<alias name="ObjectRef" c:type="JSObjectRef">
  <type name="opaque" c:type="void*">
</alias>

This seems to get past the compilation problem.  However I haven't been able to get the .deb to compile with this fix and I'm not an introspection expert - I don't know if this is correct syntax.

This is 3 years old and we now depend on g-i 1.32.0

Please reopen if you think this bug is still relevant. Thanks!
