Python Cannot Export Symbol Not Defined
Here's my example build: C:\Phil\python\Extensions\example>python setup.py build --compiler=mingw32 running build running build_ext building 'example' extension swigging example.i to example_wrap.c C:\Phil\python\Extensions\SWIG-1.3.19\swig.exe -python -o example_wrap.c example.i creating build creating build\temp.win32-2.3 creating build\temp.win32-2.3\Release c:\mingw\bin\gcc.exe Those are apparently specific to visual c++ and can be removed for use with mingw32.

Note that there is a typo: you are missing "[" right after "sources=".After running setup.py, the import worked fine.Python 2.6.5 (r265:79063, Jun 12 2010, 17:07:01)[GCC 4.3.4 20090804 (release) 1] on cygwinType If you fire up IDLE and run '>> import example' , you'll probably see an import error . pyne member scopatz commented Jun 13, 2012 Hmm, Ok yeah, I think that this means that there is something about your system that is not executing it in the right place. At the command line, could you try running: python -c "import sysconfig; print sysconfig.get_config_var('CC')" and letting us know what it says? http://stackoverflow.com/questions/18251905/python-c-extension-symbol-not-defined-error
Thanks for your post. Next, I had to remove the "-mno-cygwin" flag that is set by default by distutils (In my case, C:\Python27\Lib\distutils\cygwincompiler.py) -- it is deprecated in newer versions of gcc. Reason for doing so is that I finally did create tests to go with my pull request of 7 months ago.
In my case it was --hdf5="C:\Program Files\HDF Group\HDF5\1.8.9" pyne member scopatz commented Jun 29, 2012 Excellent! This is a little bit of a lie since in the case of pyne.cpp, this file is both valid C and valid C++. Not the answer you're looking for?

Copy this file to the same location as above (e.g. I have Python 2.3, MinGW 3.2.3, ans SWIG 1.3.19. The way to fix it is to look for a python file named "example.py" in your current working directory. I'm not sure that it's reasonable to ask the maintainers to add the DL_EXPORT macro to all module init functions, so I guess the .def files are the way to go.
For example Numeric Python *does* have a .def file for lapack_lite. It's in the Src subdirectory alongside lapack_litemodule.c, it's called lapack_lite.def, it's in Unix text format (if that matters) and it contains: EXPORTS initlapack_lite As far as I can see it is I reverted the earlier changes I had made to setup.py and unixccompiler.py, but re-added these modifications to get around the same errors we were previously seeing. Luckily that PYNE_DIR variable is only used in building on OSX.
Cython 0.18 is being used for C and C++code generation. We will now use the python distools package to do the rest of the magic for us. 4. The first problem I ran into was in setup.py everywhere "/EHsc" appeared.

I'll see what happens when I install on my Win7 desktop sometime this week. http://cluefest.com/python-cannot/python-cannot-import-name-ifilter.html Thanks again. It took two guesses to get the --hdf5= flag right. The Python executable reports the following: Python 2.1 (#1, Apr 17 2001, 09:45:01) [GCC 2.95.3-2 (cygwin special)] on cygwin_nt-4.01 I then downloaded Numeric-20.0b2 from here http://prdownloads.sourceforge.net/numpy/Numeric-20.0.0b2.tar.gz unpacked it & attempted to
wow, i am amazed how an ancient post on an inactive blog can suddenly become useful. We recommend upgrading to the latest Safari, Google Chrome, or Firefox. I was using the .zip on the install page which is evidently out of date. this contact form I do want to note that it doesn't seem like you have updated your fork in a while.
For what you are working on, this probably doesn't affect you. Are you sure that you are using a mingw version of Python? (Also, you could install EPD to make sure you have a version of mingw...) pyne member erelson commented Jun I was just using EPD out of the box on a 32-bit Win7 VM.
Hmmm, I am not even sure how you would get those TypeErrors.
pyne member scopatz commented Apr 26, 2012 @paulromano I have added a section to setup.py that will allow us to handle visual studio and cygwin separately.

Do I need some extra switches to get SWIG to create that function? But it seems that I didn't test this properly >> and broke it. You signed out in another tab or window. If all goes well, you should see no errors and upon completion, find a file named '_example.pyd' in your working directory. 6.
This can be done by changing the line that looks like exts.append(cpp_ext("pyne.lib.libpyne", ['pyne.cpp'])) to the following: exts.append(cpp_ext("pyne.lib._libpyne", ['pyne.cpp'])) Maybe I'll try to get a windows VM up on my machine this pyne member erelson commented Jun 14, 2012 Have not yet fully read the link, but I'm not seeing any change with the added underscore other than it's now not finding init_libpyne, Straight line equation How choose a proper ARIMA model looking at ACF and PACF?
