[Cython] Cython fails to build if pgen is available
Hi, I'm getting the following error trying to build Cython 0.23: Cython/Parser/Grammar: No such file or directory Traceback (most recent call last): File "setup.py", line 289, in compile_cython_modules(cython_profile, cython_compile_more, cython_with_refnanny) File "setup.py", line 135, in compile_cython_modules os.path.join(parser_dir, 'graminit.c'), File "/data/master/build/tmp/sysroots/x86_64-linux/usr/lib/python2.7/subprocess.py", line 540, in check_call raise CalledProcessError(retcode, cmd) subprocess.CalledProcessError: Command '['/data/master/build/tmp/sysroots/x86_64-linux/usr/bin/python-native/pgen', 'Cython/Parser/Grammar', 'Cython/Parser/graminit.h', 'Cython/Parser/graminit.c']' returned non-zero exit status 1 The toolchain is based on OpenEmbedded, and unlike most distribution packages, its Python installation actually contains pgen. Where would that Cython/Parser/Grammar file come from? Alternatively, is there a clean way (without patching setup.py) to skip compiling the grammar?

The grammar is here: https://github.com/cython/cython/tree/master/Cython/Parser Looks like eveyone who tried to use this did so from a git clone, not the sdist. Omission fixed: https://github.com/cython/cython/commit/969de4eab048896c6f29b9251dc4324309a1abb4 Either patch this in/distribute these files or patch setup.py. ___ cython-devel mailing list cython-devel@python.org https://mail.python.org/mailman/listinfo/cython-devel

Thanks for the report. This is a bug in the latest Cython release. I'll see if I can come up with a fix. >>> I couldn't reproduce it with any reasonable amount of test code yet, but >>> does this fix it for you? >>> >>> https://github.com/cython/cython/commit/5a40d5459aad1c6f15fb8526f0144d3c0f1dfe76 >> I am afraid not, I still get the same stacktrace. >> Let me know if there's anything else I can try. > How about this? > > https://github.com/cython/cython/commit/5fa766ac25a31b0c1addd08efd19d2d34661317b That fixes it!
