[issue18071] _osx_support compiler_fixup
New submission from Samuel John:
In the `_osx_support.py` module, there seems to be a bug in the method
`compiler_fixup` which occurs if
* the `customize_compiler` method from `distutils/sysconfig` has been called
and after that
* `_compile` from `distutils/unixcompiler.py` is called. The `_compile` method
uses `_osx_support.compiler_fixup`.
The critical line in compiler_fixup is:
`compiler_so = list(compiler_so)`.
Usually `compiler_so` is a list like `['cc']` but not when `customize_compiler`
(from sysconfig) has been called. The value returned by
`sysconfig.get_config_var('LDSHARED')` is a unicode like for example in the
case of a Python 2.7.5 built via Homebrew:
cc -bundle -undefined dynamic_lookup -L/homebrew/lib
-L/homebrew/opt/sqlite/lib -isysroot
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk.
When `list()` is applied to the value, it is split at each character and that
cannot be intended.
I am not sure if I fully understand, but to fix this in `compiler_fixup`,
instead of `compiler_so = list(compiler_so)`, I'd propose something along the
lines of:
if isinstance(compiler_so, (str,unicode)):
compiler_so = compiler_so.split()
I found this by trying to `pip install cython` (it uses customize_compiler, I
guess) on a homebrewed python.
To reproduce in an interactive shell we can emulate what is going on by calling
`compiler_fixup` directly with the values sysconfig has stored. The exact
string does not matter, because I think the any value returned by
`sysconfig_get_config_var` is a (unicode) string and not a list:
import sysconfig
import _osx_support
_osx_support.compiler_fixup(sysconfig.get_config_var('LDSHARED'),sysconfig.get_config_var('CFLAGS'))
Not sure if other python versions are affected. I wasn't aware of
`_osx_support` at all until now.

[issue18050] _sre.MAXREPEAT not defined in 2.7.3
New submission from Samuel John: As also discussed at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=704084 and https://github.com/mxcl/homebrew/pull/19300, Python 2.7.4 and 2.7.5 seem to have added an `from _sre import MAXREPEAT` to the sre_compile.py, sre_parse.py and sre_constants.py modules. But python 2.7.3 (and older?) don't have the built in MAXREPEAT in _sre. Some virtualenvs have to be updated (which is easy) but some Software (such as vim, shipped with OS X 10.8.3) is statically linked to an older python 2.7.2 (I guess) but somehow picks up my newly built python 2.7.5 and attempts to load it's site.py. (Weechat also reported to being affected) I think this is more a bug of vim/weechat etc. but we at homebrew have to do some hacky fix, because Apple is not going to update vim very soon, and so having a newer python in path breaks system stuff. So I am fine if you close this here again. But at least we have a reference or perhaps you guys have a better idea how to work-around. For homebrew, I propose a monkey-patch in re.py to the _sre module if it does not have a MAXREPEAT. try: from _sre import MAXREPEAT except ImportError: import _sre _sre.MAXREPEAT = 65535 # this monkey-patches all other places of from _sre import MAXREPEAT -- components: Extension Modules, Regular Expressions messages: 189924 nosy: ezio.melotti, mrabarnett, samueljohn priority: normal severity: normal status: open title: _sre.MAXREPEAT not defined in 2.7.3 type: crash versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue18050 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue1584] Mac OS X: building with X11 Tkinter
Samuel John added the comment: Hello from Homebrew (Mac)! Indeed we also patch setup.py (but right now only for python2.7) and uncommented the detect_tkinter_darwin related lines to support linking against a Tkinter build with homebrew (optionally with X11 support). (Our patch: https://github.com/mxcl/homebrew/pull/16626/files#L0R270) I agree that an option to tell setup.py to use another Tk would be much appreciated. -- nosy: +samueljohn ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1584 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue16848] Mac OS X: python-config --ldflags and location of Python.framework
New submission from Samuel John: Some tools use `python-config --ldflags` to get the flags in order to link against the Python lib on OS X (for example gst-python from pygtk (2.x). For framework builds, `python-config --ldflags` returns (among few other): -u _PyMac_Error Python.framework/Versions/2.7/Python which is an incomplete path. This issue is almost a duplicate of http://bugs.python.org/issue3588 and the fix discussed there would work. However I report this for Python 2.7. We at Homebrew propose a very similar fix but I'd prefer the one in issue3588: LINKFORSHARED = -u _PyMac_Error -framework Python LDFLAGS += -F$(PYTHONFRAMEWORKPREFIX) -- components: Build messages: 178936 nosy: hynek, ned.deily, ronaldoussoren, samueljohn priority: normal severity: normal status: open title: Mac OS X: python-config --ldflags and location of Python.framework type: behavior versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16848 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue13405] Add DTrace probes
Samuel John added the comment: On OS X 10.8 with Xcode only (no command line tools), I get the following err (when using clang or when using llvm-gcc): ``` dtrace: failed to compile script ./Include/pydtrace.d: Preprocessor not found make: *** [Include/pydtrace.h] Error 1 ``` At homebrew we optionally try to apply your patch to python https://github.com/mxcl/homebrew/pull/14343. I'd really like to be able to make the Command Line Tools for Xcode optional. Note, there is no cpp for clang. Usually, the CC=/path/to/clang just works. (I have seen CPP = $CC -E before, but that did *not* do the trick here).

[issue15127] Supressing warnings with -w whether gcc supports ParseTuple
New submission from Samuel John pyt...@samueljohn.de: In configrue.in, Python checks if the compiler supports __attribute__((format(PyArg_ParseTuple, 2, 3))) and sets the CFLAGS to CFLAGS -Werror to decide this test. When you build Python with CFLAGS=-w (homebrew's default), configure reports whether gcc supports ParseTuple ... yes which is not supported for clang (I was told). I know it's hard to remove a certain flag from the CFLAGS, but perhaps there should be better documentation about this issue. -- components: Build messages: 163349 nosy: samueljohn priority: normal severity: normal status: open title: Supressing warnings with -w whether gcc supports ParseTuple type: compile error versions: Python 3.2 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15127 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
