Well, I simply run:

wget ftp://ftp.kde.org/pub/kde/stable/4.4.5/src/kdenetwork-4.4.5.tar.bz2 &&
tar -xf kdenetwork-4.4.5.tar.bz2 &&
cd kdenetwork-4.4.5 &&
cmake -DCMAKE_INSTALL_PREFIX=/usr &&
make &&
make install

When I try an out-of-source build, I get the same result.  I have attached the complete build log of an out-of-source build (in kdenetwork-4.4.5/build).

Here's the relevant part of the build log from "make VERBOSE=1' (run in /etc/pupm/home/kdenetwork/tmp.9ZR/kdenetwork-4.4.5/build):

kget_export.h is located in /etc/pupm/home/kdenetwork/tmp.9ZR/kdenetwork-4.4.5/kget but this path is not specified in any -I option to /usr/bin/c++.

Can you try changing in btsettingswidget.cpp " #include "kget_export.h" " to " " #include <kget_export.h>" "? If it works, please tell me and I will put it into KDE SVN...

With <kget_export.h> it does not work, either.  However, it does work with "../../kget_export.h"  After this change, I found out that a lot of other changes are needed, too.  They are all related to the way files are included.  Here's a short shell script applying *some* of the needed changes:

sed 's|"\(kget_export.h\)"|"../../\1"|' -i\
  kget/transfer-plugins/bittorrent/btsettingswidget.cpp\
  kget/core/plugin/{plugin.h,transferfactory.h}\
  kget/core/transferdatasource.h
sed 's|<\(interfaces/trackerinterface.h\)>|"../libbtcore/\1"|' -i\
  kget/transfer-plugins/bittorrent/advanceddetails/trackermodel.h
sed 's|<\(btcore_export.h\)>|"../\1"|' -i\
  kget/transfer-plugins/bittorrent/libbtcore/btcore_export.h
sed 's|<\(util/constants.h\)>|"../libbtcore/\1"|' -i\
  kget/transfer-plugins/bittorrent/advanceddetails/webseedsmodel.h
sed 's|"\(core/plugin/transferfactory.h\)"|../../\1|' -i\
  kget/transfer-plugins/bittorrent/bttransferfactory.h
sed 's|"core/|"../|' -i\

sed 's|"core/|"|'\ -i\
  kget/core/scheduler.h
sed 's|"\(kget_export.h\)"|"../\1"|' -i\
  kget/core/{kget.h,transfergrouphandler.h}

Please note, that I have not yet run the above script and it may need some (minor) fixes; I have only tried compiling kdenetwork with the changes *implied* in the above script.

I also checked that CPATH, C_INCLUDE_PATH, CPLUS_INCLUDE_PATH and OBJC_INCLUDE_PATH are unset when I build kdenetwork.  These environment variables are documented here: http://gcc.gnu.org/onlinedocs/gcc-4.5.0/cpp/Environment-Variables.html#Environment-Variables.

Well cmake should take care of them if they are needed...

I still wonder what is wrong as the CMakeLists.txt do have a:
include_directories(
    ../../
)
which is the path of kget_export.h...

The following is an excerpt from kget/transfer-plugins/bittorrent/CMakeLists.txt:

if (GMP_FOUND AND QCA2_FOUND)
include_directories(
   ../../
   libbtcore
   ${QCA2_INCLUDE_DIR}
   ${GMP_INCLUDE_DIR}
)

Obviously, the specified paths (incl. ../../) will only be used if both GMP and QCA2 are installed.  On my system QCA2 was not installed...

Well do you have libbtcore installed?

Btw, this error should be already fixed in 4.5 if what you describe is the cause of it... :)

> Well do you have libbtcore installed?

No, I don't.

Mmh yes, you're catching a corner-case of the CMakeLists.txt... if you install QCA2 and GMP it will work then :)

It is also already fixed in 4.5 and trunk...

Thanks for reporting anyway, I'm closing this... ok?

If it is already fixed upstream, it's OK to close it.  Thanks for pointing me to CMakeLists.txt...
