After upgrading to gcc-4.6 I found that qt-meta-3.3.8b-r2 (from kde-sunset overlay) failed to compile.
Searching the net I found that other packages failed similarly with errors like this one:
Code:
./include/qvaluelist.h:88:13: error: ‘ptrdiff_t’ does not name a type

With this information I made a patch so I can continue using my kde-3.5.10.

I thought to post the patch here for whoever may have the same problem.

Here is the patch:

Code:

It simply adds the line:
Code:
#include <stddef.h>

to the beginning of the files: /src/tools/{qmap.h, qvaluelist.h}

Happy kde-3.5.10ing :D

proteusx,

missing includes are a known phenomenon with gcc 4.6.
I think you should create a bug (if none exists already) on b.g.o. so that patch can be included in the sunrise tree.
Upstream will be interested in this too.

There is no upstream for Qt3 anymore and bugzilla is not the place to report kde-sunset bugs, the gentoo-desktop mailing list is as per

http://git.overlays.gentoo.org/gitweb/?p=proj/kde-sunset.git;a=tree;f=Documentation;hb=HEAD

@alex
As suominen says, bugzilla frowns upon bug reports on unsupported software.

Those of us still runnning kde:3.5 need to do a bit of work to keep it going,
and need to support eachother.

When sometime ago I was in a pickle with kdelibs:3.5, I found this post :
kde-base/kdelibs-3.5.10-r10 failed (compile phase)
very helpfull.

Thanks for the clarification, ssuominen.

As KDE 3 is now "old", then would it not be simpler to compile it with an older GCC, like 4.2.* or 4.3.* ?
Would that not solve the problem?

I think kde-4 is quite good also

Maybe it would but
I keep finding packages that will only compile with >gcc-4.5
and it is a hassle switching the compiler back and forth.

Although I still use kde:3.5, I also use many kde:4 apps
such as okular, k3b, okteta, kde4-konsole and others..
