今天折腾kde-telepathy遇到了好几个问题，这里记录下。
1、telepathy-qt安装问题，导致net-im/ktp-common-internals-9999编译失败
net-im/ktp-common-internals-9999在编译的时候提示找不到DBusError头文件，这个文件应该由telepathy-qt提供。用equery查看了下telepathy-qt安装的文件，的确没有发现这个目录。因为本机装的telepathy-qt也是9999版本，去本地git源里面clone了一份，发现里面是有这个文件的，仔细查看了TelepathyQt/CMakeLists.txt文件，发现如果要安装DBusError这个头文件，必须在cmake配置的时候开启ENABLE_EXPERIMENTAL_SERVICE_SUPPORT。搜索这个变量，可以发现最外层的CMakeLists.txt文件定义了：
[cce lang="cmake"]
option(ENABLE_EXPERIMENTAL_SERVICE_SUPPORT "Enable compilation of experimental and unstable service side bindings for Telepathy-Qt" FALSE)
[/cce]
然后就是去改ebuild文件了。修改很简单，就是在configure的时候增加这个开关，这里的方式是增加了一个USE：
[cce lang="diff"]

2、ktp-text-ui编译失败
ktp-text-ui编译的时候提示：
[cce]
usr/include/boost-1_48/boost/type_traits/detail/has_binary_operator.hp:50: Parse error at "BOOST_JOIN"
automoc4: process for /chroot/local/portage/net-im/ktp-text-ui-9999/work/ktp-text-ui-9999_build/logviewer/moc_entity-model.cpp failed: Unknown error
pid to wait for: 0
returning failed..
[/cce]
的问题，发现这个是qt的moc的问题，已经有相关的bug了：
https://bugs.kde.org/show_bug.cgi?id=296137
https://bugreports.qt-project.org/browse/QTBUG-22829
解决方案参照http://cgit.freedesktop.org/gstreamer/qt-gstreamer/commit/?id=2cc5399d70d4d6caf8d05df9ca51f5448d545b67这里的，给所有提示moc失败的类的头文件上加上Boost相关宏定义BOOST_TT_HAS_OPERATOR_HPP_INCLUDED
具体补丁：

自己改下ebuild文件，打上这个补丁就OK了。
另外还有一个问题，就是msn用xmpp方式连接，总是提示network error，无法连接到messenger.live.com，找到http://blogs.fsfe.org/drdanz/?p=632&cpage=1#comment-14534 这篇博客的评论。但是gentoo仓库最新的telepathy-gabble只有0.14.1，还得自己写ebuild，明天再说了。
