Subject: [gentoo-user] Threading issues with compiling Qt apps

1 Hi,
3 I want to double check some things here first before I report a bug,
4 just in case the problem is in the fingers. arch = ~x86
6 Emerging amarok and kde-base/kopete both fail with this error in the
7 configure step:
9 =======================
10 checking for Qt... configure: error: Qt (>= Qt 3.3 and < 4.0) (library
11 qt-mt) not found. Please check your installation!
12 For more details about this problem, look at the end of config.log.
13 Make sure that you have compiled Qt with thread support!
14 =======================
16 The amarok build log contains this:
18 =======================

32 =======================
34 The kopete log contains much the same. It seems like I have faulty glibc
35 build settings, and this will happen for all future Qt builds. I
36 haven't had to remerge a Qt app for a while and the most recent
37 relevant change I can think of was to glibc-2.5: remove nptlonly and
38 add glibc-compat20. My full USE flags for related apps:
