This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: Python's ctypes module is unable to access libraries that are stored in /usr/local/lib Version-Release number of selected component (if applicable): [dwayne@localhost lib]$ python --version Python 2.5.1 How reproducible: I have a custom compiled libgettextpo in /usr/local/lib but not in /usr/lib running the script that follows produces the error Steps to Reproduce: 1. Make sure you have a library in /usr/local/lib but not in /usr/lib 2. Run the following test script that does - find_library <script> from ctypes import * lib_location = ctypes.util.find_library('gettextpo') print lib_location </script> 3. Run the following test script that does LoadLibrary <script> from ctypes import * import ctypes.util lib_location = ctypes.util.find_library('gettextpo') gpo = cdll.LoadLibrary(lib_location) </script> 4. Symblink the /us/local/lib/libgettextpo.so.0 to /usr/lib 5. Run the scripts again Actual results: First script succeeds with output of: libgettextpo.so.0 Indicating that it was able to find the library version in /usr/local/lib The second fails with the following traceback: Traceback (most recent call last): File "ctypes-test.py", line 7, in <module> gpo = cdll.LoadLibrary(lib_location) File "/usr/lib/python2.5/ctypes/__init__.py", line 423, in LoadLibrary return self._dlltype(name) File "/usr/lib/python2.5/ctypes/__init__.py", line 340, in __init__ self._handle = _dlopen(self._name, mode) OSError: libgettextpo.so.0: cannot open shared object file: No such file or directory Indicating that it couldn't find the library Once the symlink step is executed loading and execution continue correctly. Expected results: A library in /usr/local/lib should simply load as expected.
