this is on OpenSolaris b124 with Sun Studio 12U1

Hi,

I can't seem to see this error myself... I don't really know how the K_DECLARE_PRIVATE macro works... 

Also your build link in the description fails above.

All I can suggest just now is this patch:

--- a/phonon/experimental/globalconfig.h
+++ b/phonon/experimental/globalconfig.h
@@ -39,7 +39,7 @@ namespace Experimental
 
 class GlobalConfig : public Phonon::GlobalConfig
 {
-    K_DECLARE_PRIVATE(GlobalConfig)
+    K_DECLARE_PRIVATE(Phonon::GlobalConfig)
 public:
     QList<int> videoCaptureDeviceListFor(Phonon::Category category, int override = AdvancedDevicesFromSettings) const;
     int videoCaptureDeviceFor(Phonon::Category category, int override = AdvancedDevicesFromSettings) const;


All I know is that it doesn't break build for me and perhaps with the specific namespacing, it will fix your error?

I don't really speak C++ :-(
comparing with the phonon/globalconfig.h header file I tried this patch:

which got rid of the reported error, but failed anyway with

line 74: Error: The type "const Phonon::Experimental::GlobalConfigPrivate" is

Comment 3 Colin Guthrie 2009-11-26 17:46:20 UTC

Yeah that fix wont work... it just adds a forward declaration for the class, but doesn't define it.

Did you try my patch? Did it not work?

Comment 4 tropikhajma 2009-11-26 17:50:49 UTC

Just got my hands on the build system :-)
Yes with this patch phonon builds completely.
Thanks!

Comment 5 Colin Guthrie 2009-11-26 18:17:20 UTC

Cool. I guess I'll commit it then :)

Comment 6 Colin Guthrie 2009-11-26 18:22:07 UTC

SVN commit 1054743 by cguthrie:

experimental: Use full namespace on Phonon::GlobalConfig in Experimental::GlobalConfig

It seems some compilers (e.g. the one used on Solaris/Sun Studio 12 U1) need this to compile cleanly.

CCBUG: 216158

Marking as fixed.
