Hi Phil,
there has been a bug report about g++-4.3-related build problems, can
you comment on that, please?
BTW, are you aware of the severe performance problems when compiling
sip-generated code with g++ 4.2? It has improved with recent 4.3
snapshots, but is still not as fast as 4.1 used to be. Splitting PyQt4
into 40 parts and compiling with -O1 runs through "fast enough".
Please see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30052
In other news, thanks for the tips wrt qreal/float, it now builds fine
on all arches!
best,
Torsten
