Hi,
I've compiled the latest PyQt5 snaphot, on 32bit python 3.3.1 (compiled with
mingw, using a self-made
build script based on scons), Windows7, Qt 5.1alpha.
I've used this configuration step:
D:\_cpp_projects_\Python\Python-3.3.1\.build_release\python.exe configure.py
--no-docstrings --confirm-license -u --spec=win32-g++ --verbose --trace
--sip="D:\_cpp_projects_\Python\Python-3.3.1\sip.exe"
LFLAGS+="-LD:\_cpp_projects_\Python\Python-3.3.1\.build_debug
-LD:\_cpp_projects_\Python\Python-3.3.1\.build_release" DEFINES+=_DEBUG
(It's necessary to include the release version of the python lib even in debug
build for the designer
plugins.)
I've run into a number of problems:
(1)
PyQt's configure.py autoamtically assumes certain MS-compilers on the win32
platform, in
TargetConfiguration.__init__():262 and following:
# The default qmake spec.
if sys.platform == 'win32':
if self.py_version >= 0x030300:
#self.qmake_spec = 'win32-msvc2010'
---- self.qmake_spec = 'win32-g++'
elif self.py_version >= 0x020600:
self.qmake_spec = 'win32-msvc2008'
elif self.py_version >= 0x020400:
self.qmake_spec = 'win32-msvc.net'
else:
self.qmake_spec = 'win32-msvc'
else:
# Use the Qt default. (We may update it for MacOS/X later.)
self.qmake_spec = ''
I had to make the marked change to get around that for my mingw-based python.
It would be nice
if there was an option to influence that.
[Motivation: I must embedd the python interpreter, and I want to get away from
MS Visual Studio,
because it is becoming slower with each version. Hence I'll have to compile
python myself using
mingw, which is non-standard.]
(2)
All makefiles attempt to build all DLLs without referring to the python DLL.
Adding
"-lpython33_d" to each Makefile.Debug and "-lpython33" to Makefile.Release
solves this.
I tried adding LFLAGS_DEBUG+="-lpython33_d" as parameter to the configure
script, but it had
no effect on the makefiles.
(3)
The final debugging versions of the DLLs get the wrong names. They all miss the
trailing "_d".
This way they can't be imported, unless manually renamed arcordingly.

Mathias Born
