Hi guys
I'm having problems building PyQt4 from source using MinGW under
Windows XP. Here are the steps I went through, with detail about each
of the problems. I'm hoping this information will help you fix some of
the mess. I also hope that it will be convincing enough to make it
obvious that it is a bit painful right now.
0. - I adjusted my PATH to include C:/MinGW/bin
- I'm running all of the code below in a Cygwin bash shell.
1. I installed Qt-4.3.0 Open Source using the .exe file from
trolltech's website.
2. Installing sip: since there is no Windows binary available for sip,
I downloaded the snapshot source: sip-snapshot-20070704, unzipped
it. From there I followed the instructions::
C:/Python25/python.exe configure.py -p win32-g++
make # using Cygwin's GNU make
make install
**ERROR**, this ``make install`` fails::
[EMAIL PROTECTED] /cygdrive/c/tmp/sip-snapshot-20070704
$ make install
make[1]: Entering directory `/cygdrive/c/tmp/sip-snapshot-20070704/sipgen'
/bin/sh: -c: line 1: syntax error: unexpected end of file
make[1]: *** [install] Error 2
make[1]: Leaving directory `/cygdrive/c/tmp/sip-snapshot-20070704/sipgen'
make: *** [install] Error 2
Workaround: I copied the files manually to the Python
installation::
cp sip*.py siplib/sip.pyq C:/Python25/Lib/site-packages
``import sip`` works from Python. So I'm moving on.
3. Installing PyQt: same, I have to use the snapshot until there is a
release for 4.3.0. I downloaded the snapshot (20080710), unpacked
it, and am trying to configure it::
$ C:/Python25/python configure.py -p win32-g++
Determining the layout of your Qt installation...
Error: Make sure you have a working Qt v4 qmake on your PATH or use the -q
argument to explicitly specify a working Qt v4 qmake.
So I look for qmake.exe in the Qt installation, and it is in
C:/Qt/4.3.0/qmake/qmake.exe, so I do::
$ C:/Python25/python configure.py -p win32-g++ -q
C:/Qt/4.3.0/qmake/qmake.exe -w
Determining the layout of your Qt installation...
C:\Qt\4.3.0\qmake\qmake.exe -o qtdirs.mk qtdirs.pro

Fine, I'll set QMAKESPEC::
$ export QMAKESPEC="win32-g++"
I'll set QTDIR as well::
$ export QTDIR=C:/Qt/4.3.0
It still fails::
$ C:/Python25/python configure.py -p win32-g++ -q
C:/Qt/4.3.0/qmake/qmake.exe -w
Determining the layout of your Qt installation...
C:\Qt\4.3.0\qmake\qmake.exe -o qtdirs.mk qtdirs.pro
Could not find mkspecs for your QMAKESPEC(win32-g++) after trying:

Error: C:\Qt\4.3.0\qmake\qmake.exe failed to create a makefile.
Make sure you
have a working Qt v4 qmake on your PATH or use the -q argument to
explicitly
specify a working Qt v4 qmake.
**ERROR**: How do I change the root of the ``mkspecs`` files for
qmake? It does not seem to have an option.
After a fair amount of searching, I find that QMAKEPATH is the
variable that will help me here::
$ export QMAKEPATH=C:/Qt/4.3.0
(This needs to be document more clearly somewhere, or the problem
needs to be fixed somehow.)
Moving on, it still fails::
$ C:/Python25/python configure.py -p win32-g++ -q
C:/Qt/4.3.0/qmake/qmake.exe -w

``qmake.exe` is apparently still looking at

**ERROR** After spending 45mins fiddling with numerous variables
that I would expect to influence qmake (searching a lot on the
web), I cannot seem to make it change the include file. How do I
do that?
Allright, so I can't do this, damnit. Fine, I'll copy QTDIR where
it wants it, let's move into kludge-paradise::
$ cd C:/
$ mkdir -p C:/iwmake
$ cp -r C:/Qt/4.3.0 C:/iwmake/build_mingw_opensource
This time it cannot find my mingw32::

Look at that 4.2.2, what is that? So I grep and find it in
configure.py::
$ grep -sr 4.2.2 .

It does not make a difference, same error.
I grep all over, in my Qt installation, in PyQt, to no avail.
I ran a find on my system, there is not other libQtCore4.a other
than the newly installed one in C:/Qt/4.3.0/lib/libQtCore4.a.
Any help appreciated. I'm stuck. Well, you know, for now. Stuck for now.
(It's a little painful and fiddling with Windows I feel like my life
is passing me by, you know.)
