[Cython] Possible Freeze-related regression from 0.14 to 0.14.1
My project using Cython-freeze compiles properly with Cython 0.14.0 but fails with 0.14.1. I run Python 2.5 on Debian Lenny and the cython_freeze from github (October 29, 2009). The attached simple test case (1 plain .pyx and .pxd, 1 .pyx with main(), and a makefile) demonstrates the issue- it works under 0.14.0 and fails under 0.14.1. The issue appears to be that Cython 0.14.0 declares an "int __pyx_module_is_main_mainster = 0" in mainster.c, while 0.14.1 declares it as static: "static int __pyx_module_is_main_ mainster = 0". When linking the object files, this results in the error from GCC: gcc -Xlinker -export-dynamic -Wl,-O1 -Wl,-Bsymbolic-functions -L/usr/lib/python2.5/config executable.o mainster.o foo.o -lpython2.5 -lm -lpthread -ldl -lutil -o executable executable.o: In function `main': [...]/executable.c:54: undefined reference to `__pyx_module_is_main_mainster' collect2: ld returned 1 exit status make: *** [executable] Error 1 If I remove "static" from the declaration in mainster.c, I can recompile it and link the object files as I could do with Cython 0.14.0. Let me know if you need more details or if it's not a bug at all and there's a workaround. My workaround for now will be to use 0.14.0.

Of course I would forget to attach the test case.

Now this testcase should run from ancient Python 2.3 to head Python 3.2, both for static and sharedlib builds (but not in Windows). -- Lisandro Dalcin --- CIMEC (INTEC/CONICET-UNL) Predio CONICET-Santa Fe Colectora RN 168 Km 472, Paraje El Pozo 3000 Santa Fe, Argentina Tel: +54-342-4511594 (ext 1011) Tel/Fax: +54-342-4511169 ___ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
