The PyQt configuration documentation (http://www.riverbankcomputing.co.uk/static/Docs/PyQt4/pyqt4ref.html#configuring-pyqt
) includes the following option:
The C++ source files for a Python module will be concatenated. This
results in significantly reduced compilation times. Most, but not all,
C++ compilers can handle the large files that result. It is
recommended that you use this option if you are using GCC v3.x or MSVC
v7.x. See also the --concatenate-split option.
On a quad-core Mac running OS 10.6 (Snow Leopard) I tried the
compilation both with and without -c, using the system gcc (4.0.1).
The -c compilation was 10 times SLOWER than the regular compilation!
Perhaps the documentation could clarify when the option is a good idea
and when not.
