[issue4279] Module 'parser' fails to build
Mark Sapiro m...@msapiro.net added the comment: This problem also occurs when building the 2.6.1 parser module on Cygwin 1.5.25. It did not occur with Python 2.6 or 2.5.x. The error from 'make' is building 'parser' extension gcc -shared -Wl,--enable-auto-image-base build/temp.cygwin-1.5.25-i686-2.6/cygdrive/c/Python_dist/Python-2.6.1/Modules/parsermodule.o -L/usr/local/lib -L. -lpython2.6 -o build/lib.cygwin-1.5.25-i686-2.6/parser.dll build/temp.cygwin-1.5.25-i686-2.6/cygdrive/c/Python_dist/Python-2.6.1/Modules/parsermodule.o: In function `parser_expr': /cygdrive/c/Python_dist/Python-2.6.1/Modules/parsermodule.c:552: undefined reference to `__PyParser_Grammar' build/temp.cygwin-1.5.25-i686-2.6/cygdrive/c/Python_dist/Python-2.6.1/Modules/parsermodule.o: In function `parser_suite': /cygdrive/c/Python_dist/Python-2.6.1/Modules/parsermodule.c:552: undefined reference to `__PyParser_Grammar' collect2: ld returned 1 exit status I was able to work around the error and build a parser module that passed unit test by manually running gcc -shared -Wl,--enable-auto-image-base build/temp.cygwin-1.5.25-i686-2.6/cygdrive/c/Python_dist/Python-2.6.1/Modules/parsermodule.o Python/graminit.o -L/usr/local/lib -L. -lpython2.6 -o build/lib.cygwin-1.5.25-i686-2.6/parser.dll i.e. by including Python/graminit.o in the explicit object files to load. I have also confirmed that applying the parser-grammar.patch from #4288 will allow make to successfully build a parser module that passes unit tests. -- nosy: +msapiro versions: +Python 2.6 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue4279 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Yaakov (Cygwin Ports) [EMAIL PROTECTED] added the comment: Attempting to export and use Py_meta_grammar() gives me a broken module, based on the results of test/test_parser.py. This patch, which exports _PyParser_Grammar, is very simple and the test passes. I will gladly take guidance on this patch.

Yaakov (Cygwin Ports) [EMAIL PROTECTED] added the comment: I can confirm this problem in 3.0rc3 on Cygwin. If I could get some direction from the Python devs on which method would be preferred (accessor function vs. exposing data structure), I would be happy to provide a patch. -- nosy: +yselkowitz ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue4279 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Andy [EMAIL PROTECTED] added the comment: Martin: Looking at it I agree with you 100% - the patch is too complicated for what it is intending to resolve. It simply does not need another accessor function to muddy the waters when making the symbol public as done in #4288 resolves the issue. My personal preference is to try to hide such data structures - but that doesn't always mean its the correct thing to do :-) ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue4279 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Martin v. Löwis [EMAIL PROTECTED] added the comment: As Christian said in #4288: this links in a separate of metagrammar.c, which is undesirable. However, I think you can fix this by exporting Py_meta_grammar from pythonxy.dll. -- nosy: +loewis ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue4279 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue4279] Module 'parser' fails to build
Andy [EMAIL PROTECTED] added the comment: a new patch that will use the grammar definition from Python/graminit.c - it is as of yet untested for Cygwin (can't get to that machine right now). It follows the same pattern as the previous, i.e. it makes us of an accessor function to get the grammar definition. This has expanded the patch somewhat to include changes to: - setup.py for Cygwin environment. - Parser/pgenmain.c to write out the function body - Python/pythonrun.c to use the new function - Include/grammar.h to declare the new function - Modules/parsermodule.c to use the new function All of which makes me think that the change to make the symbol public and use it directly without hiding it is a better way to go. Will look at this under my Cygwin environment tomorrow. (I have run a configre - make - test cycle on Ubuntu (hardy heron) and it is OK [but then its not broken there anyway :-) ] ) Added file: http://bugs.python.org/file11970/nu_diff.txt ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue4279 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Martin v. Löwis [EMAIL PROTECTED] added the comment: That patch is too complicated. We already have meta_grammar and Py_meta_grammar, and now you also add a third function (get_PyParserGrammar) that does the same thing again. I don't see why you can't call one of the existing functions, and I fail to see the need to change pythonrun.c at all. ___ Python tracker [EMAIL PROTECTED] http://bugs.python.org/issue4279 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
