I suppose it's trying to tell me something, but I'm not
sure what.

This worked for me (with Python 2.4 final, without any
patch). I wasn't aware that this simple solution existed.
You're right, this should be in the documentation. Many thanks.

The solution or workaround is to either run
'python setup.py build --compiler=whatever bdist_wininst'
or insert 'compiler=whatever' in a setup.cfg file.
I have explained this several times, IMO something should be
added to the distutils documentation about this (but I don't
have the time).

Well this is a severe bug in Python 2.4: Users of compilers
other than Microsoft can no longer build extension modules
for Python on Windows. (Well they can build one, but they
cannot install it nor create a binary installer). So I wrote
a patch for msvccompiler.py and submitted it to sourceforge
(see patch 1075887). Could you do me a favor and have a look
at this patch (or have somebody else look at it)? There are
lots of patches for Python 2.4 already, some very old, and
I'm worried that it may take a long time before this gets fixed.

That's an incorrect assumption: bdist_wininst does a
full "build" before it builds the installer. All standard distutils
commands work this way; you don't have to run them in any
specific order.
I suggest you open a new, more specific bug ("bdist_wininst
relies on msvccompiler"), and follow up with a message to the
python-dev.
It might be too late for 2.4 (it's been this way through the
alpha and beta releases, without anyone noticing), but
maybe some distutils expert can come up with a workaround
(or explain how this really is supposed to work).

No, it didn't work for any of the 2.4 releases, but it did
work for Python 2.3 and 2.2:
$ /cygdrive/c/Python23/python setup.py build --compiler=mingw32
... compiles the extension module using gcc
$ /cygdrive/c/Python23/python setup.py bdist_wininst
running bdist_wininst
running build
running build_py
running build_ext
installing to build\bdist.win32\wininst
running install_lib
.... creates the installer.
> Does it work if you pass in the --compiler switch to
bdist_wininst?
No, it doesn't, I get the following error message:
$ /cygdrive/c/Python24/python setup.py bdist_wininst
--compiler=mingw32
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2
[cmd2_opts] ...]
or: setup.py --help [cmd1 cmd2 ...]
or: setup.py --help-commands
or: setup.py cmd --help
error: option --compiler not recognized
This makes sense, because no compilation is needed to create
the installer.
>From looking at msvccompiler.py, it looks like the problem
is that self.__macros = MacroExpander(self.__version) is
called when creating the MSVCCompiler, before we know if
anything is left that still needs to be compiled.
A solution might be to leave self.__macros None in __init__,
and check it in the compile function. If it is still None
there, we can make the call to MacroExpander then. Users of
gcc will not need to run MSVCCompiler's compile function, so
they will not run into MacroExpander.
There is one remaining problem in __init__:
if len (self.__paths) == 0:
raise DistutilsPlatformError, ("Python was built with version %s
of Visual Studio, "
"and extensions need to be built with the same "
"version of the compiler, but it isn't
installed." % self.__version)
Is this true? It would imply that gcc can't be used at all.
However, extension modules built with gcc seem to work
correctly with Python 2.4, as far as I can tell.

The patch only changed the error message; earlier versions
gave a KeyError exception. Are you really claiming that this
worked in earlier 2.4 releases?
Does it work if you pass in the --compiler switch to
bdist_wininst?

The patch probably works fine for Microsoft users, but now
gcc users get an unhelpful error message:
$ /cygdrive/c/Python24/python setup.py build --compiler=mingw32
... runs fine, using gcc compiler ...
... now let's try to make the installer:
$ /cygdrive/c/Python24/python setup.py bdist_wininst
running bdist_wininst
running build
running build_py
running build_ext
error: The .NET Framework SDK needs to be installed before
building extensions for Python.
I'm not sure why distutils is running msvccompiler.py. To
check if all components have been compiled and are ready to
be included into the installer, it shouldn't matter which
compiler was used during the build step.

Please check patch 1071739.
The updated report is:
D:\SRC\Imaging-1.1.5b1>python setup.py build_ext -i
running build_ext
error: The .NET Framework SDK needs to be installed before

Makes sense to me.

Please forgive my previous quadruple followup.
This page ( http://www.vrplumber.com/programming/mstoolkit/
) is relevant. The message about sdkinstallroot1.1 should
be related to the .NET Framework SDK v1.1 not being installed.
I would wrap the offending line in load_macros function and
throw an exception with more informative args. Do you want
me to?
PS I attempted to "pass" the failing statement in line 128
(in the load_macros function); building Imaging complains
that VS 7.1 is not installed.

I get the same message trying to build PIL with 2.4rc1,
having installed the VC++ toolkit (free command line
compiler), so it's not a problem of VS 6. I assume/fear
that the .NET SDK framework needs to be installed.

Note that the same error occurs with python setup.py install
(using Python 2.4b1):
C:\somewhere> python setup.py build
....
File "c:\Python24\lib\distutils\msvccompiler.py", line
118, in set_macro
self.macros["$(%s)" % macro] = d[key]
KeyError: 'sdkinstallrootv1.1'
Using MinGW for the compilation works:
C:\somewhere> python setup.py build --compiler=mingw32
....
compiles without errors. However, the install still fails:
C:\somewhere> python setup.py install
File "c:\Python24\lib\distutils\msvccompiler.py", line
118, in set_macro
self.macros["$(%s)" % macro] = d[key]
KeyError: 'sdkinstallrootv1.1'

Yep. Can you produce a small patch for this? I have no
access to MSVC 6 or 7 (in fact, my Windows box won't even
boot at the moment).

If I'm using the wrong compiler, distutils should say so,
instead of showing me a 10-level KeyError traceback...

It looks (to me) like it's expecting you to have some
additional package (Framework SDK?) installed. The code in
question was added as part of the MSVC7 support - are you
building with MSVC6?
