During gnome-2.20 developpement cycle, I've been hit by python-2.5 update. On my main box I started seing some gnome python apps failing. The two examples right now are deskbar-applet and net-p2p/deluge. Those apps fail with: ImportError: /usr/lib/python2.5/lib-dynload/zlib.so: undefined symbol: inflateCopy I recently found out that python installs its test file, and obviously running the appropriate test gives: # python /usr/lib/python2.5/test/test_zlib.py Traceback (most recent call last): File "/usr/lib/python2.5/test/test_zlib.py", line 3, in <module> import zlib ImportError: /usr/lib/python2.5/lib-dynload/zlib.so: undefined symbol: inflateCopy I've tried various combinations of safe CFLAGS, removed LDFLAGS, tried on other boxes (pII, amd64, ...) and I can't reproduce it. readelf -s /usr/lib/python2.5/lib-dynload/zlib.so Symbol table '.dynsym' contains 46 entries: Num: Value Size Type Bind Vis Ndx Name 0: 00000000 0 NOTYPE LOCAL DEFAULT UND 1: 00000000 266 FUNC GLOBAL DEFAULT UND PyModule_AddObject 2: 00000000 94 FUNC GLOBAL DEFAULT UND inflateEnd 3: 00000000 4 OBJECT GLOBAL DEFAULT UND PyExc_ValueError 4: 00000000 57 FUNC GLOBAL DEFAULT UND PyModule_AddStringConstan 5: 00000000 0 NOTYPE WEAK DEFAULT UND __gmon_start__ 6: 00000000 0 NOTYPE WEAK DEFAULT UND _Jv_RegisterClasses 7: 00000000 2714 FUNC GLOBAL DEFAULT UND deflate 8: 00000000 89 FUNC GLOBAL DEFAULT UND deflateInit_ 9: 00000000 67 FUNC GLOBAL DEFAULT UND _PyObject_New 10: 00000000 139 FUNC GLOBAL DEFAULT UND PyThread_allocate_lock 11: 00000000 311 FUNC GLOBAL DEFAULT UND PyString_FromStringAndSiz 12: 00000000 62 FUNC GLOBAL DEFAULT UND Py_FindMethod 13: 00000000 57 FUNC GLOBAL DEFAULT UND PyModule_AddIntConstant 14: 00000000 304 FUNC GLOBAL DEFAULT UND inflateInit2_ 15: 00000000 107 FUNC GLOBAL DEFAULT UND PyErr_Format 16: 00000000 35 FUNC GLOBAL DEFAULT UND PyArg_ParseTuple 17: 00000000 7061 FUNC GLOBAL DEFAULT UND inflate 18: 00000000 227 FUNC GLOBAL DEFAULT UND free@GLIBC_2.0 (2) 19: 00000000 51 FUNC GLOBAL DEFAULT UND PyThread_release_lock 20: 00000000 1550 FUNC GLOBAL DEFAULT UND crc32 21: 00000000 230 FUNC GLOBAL DEFAULT UND deflateEnd 22: 00000000 117 FUNC GLOBAL DEFAULT UND PyEval_RestoreThread 23: 00000000 4 OBJECT GLOBAL DEFAULT UND PyExc_MemoryError 24: 00000000 327 FUNC GLOBAL DEFAULT UND PyString_FromString 25: 00000000 130 FUNC GLOBAL DEFAULT UND PyInt_FromLong 26: 00000000 87 FUNC GLOBAL DEFAULT UND PyEval_SaveThread 27: 00000000 192 OBJECT GLOBAL DEFAULT UND PyType_Type 28: 00000000 376 FUNC GLOBAL DEFAULT UND malloc@GLIBC_2.0 (2) 29: 00000000 502 FUNC GLOBAL DEFAULT UND PyErr_NewException 30: 00000000 547 FUNC GLOBAL DEFAULT UND deflateCopy 31: 00000000 712 FUNC GLOBAL DEFAULT UND deflateInit2_ 32: 00000000 729 FUNC GLOBAL DEFAULT UND Py_InitModule4 33: 00000000 445 FUNC GLOBAL DEFAULT UND PyObject_Free 34: 00000000 225 FUNC GLOBAL DEFAULT UND _PyString_Resize 35: 00000000 99 FUNC GLOBAL DEFAULT UND PyErr_SetString 36: 00000000 947 FUNC GLOBAL DEFAULT UND adler32 37: 00000000 247 FUNC WEAK DEFAULT UND __cxa_finalize@GLIBC_2.1.3 (3) 38: 00000000 422 FUNC GLOBAL DEFAULT UND inflateCopy 39: 00000000 172 FUNC GLOBAL DEFAULT UND PyThread_acquire_lock 40: 00000e80 587 FUNC GLOBAL DEFAULT 11 initzlib 41: 00004eec 0 NOTYPE GLOBAL DEFAULT ABS _end 42: 00004ee0 0 NOTYPE GLOBAL DEFAULT ABS _edata 43: 00004ee0 0 NOTYPE GLOBAL DEFAULT ABS __bss_start 44: 00000b70 0 FUNC GLOBAL DEFAULT 9 _init 45: 00002ac4 0 FUNC GLOBAL DEFAULT 12 _fini the symbol is here so wth is happening here ???

a few more informations: the ebuild passes tests for this module (python-2.5) and the test works with python-2.4.4-r5
Hi guys, did more tests and strace today to finaly find out what was wrong. There were stale files on my system : lrwxrwxrwx 1 root root 13 jui 9 2004 /usr/lib/libz.so.1 -> libz.so.1.1.4 -rwxr-xr-x 1 root root 54416 avr 12 2004 /usr/lib/libz.so.1.1.4 Don't exactly know why they where still there, probably a leftover from a Ctrl+C of portage in a cleaning phase. The problem was that python tried to open /usr/lib/libz.so.1 _before_ /lib/libz.so.1. For some reason, I don't have /lib in any LDPATH defined in /etc/env.d on this box. This is not the only box with this "error", but it's the only having old libz in /usr/lib so I guess it explains it all.
