Hello,
I had PyQt5 working with Qt5.0.2 and Python 2.7but decided to dump my Qt5.0.2
and install the new Qt5.1. My environment is mac OS X 10.7.5 which is the
latest version of Lion.
Qt5.1 installed without issues.
SIP installed without issues.
Running python configure.py for PyQt-gpl-5.0 failed with an error, "Error:
Unable to create the C++ code." The sources were in a folder on my desktop as
they were last time I installed PyQt5 against Qt5.0.2 albeit without this
error. I Googled and found that spaces in a path have caused this error in the
past and by moving the PyQt source directory to my user directory solved this
issue and I was then able to run python configure.py without further errors or
warnings.
I ran "make clean" and then ran "make" . I had a few warnings that various Qt
directories could not be found similar to "warning: directory not found for
option '-F/Users/chris/Qt//5.1.0/clang_64/qttools/lib'" it turns out this is a
known bug with qmake, QTBUG-28336, that hadn't shown up until more
modularization of Qt for Qt5.1. But long after the warnings and it was
starting to look like it was getting close to finishing I got a list of eight
duplicate symbols and the following error.
"ld: 8 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [pylupdate5] Error 1
make: *** [sub-pylupdate-make_first-ordered] Error 2""
I was able to find a work around for the warnings by creating symlinks to the
actual directories. Doing this though did not solve the duplicate symbols
problem.
Running "make clean" and "make --silent" results in the following,
"Makefile:1481: warning: overriding commands for target `moc_translator.o'
Makefile:989: warning: ignoring old commands for target `moc_translator.o'
duplicate symbol
__ZN10Translator18qt_static_metacallEP7QObjectN11QMetaObject4CallEiPPv in:

ld: 8 duplicate symbols for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [pylupdate5] Error 1
make: *** [sub-pylupdate-make_first-ordered] Error 2"
So there were two warnings that were probably there prior and I missed them
among all the echoed commands and are clearly connected with the duplicate
symbols. What I have not been able to figure out though is exactly why this is
happing and how to fix it. I have not manually edited any of the PyQt files
and I would think "make clean" should have taken care of duplicates from my
prior install of PyQt5 left over in the sources directory.
I'm hoping that someone with more knowledge and experience can point me in the
right direction for solving this.
Thank you kindly,
~Chris
