From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.6) Gecko/20050317 Firefox/1.0.2 Description of problem: This is a known bug, see http://www.tug.org/texinfohtml/kpathsea.html#Unable-to-find-files, the 3rd bullet. To repeat briefly, if a directory d being searched for subdirectories contains plain files and symbolic links to other directories, but no true subdirectories, d will be considered a leaf directory, i.e., the symbolic links will not be followed. You can work around this problem by creating an empty dummy subdirectory in d. Then d will no longer be a leaf, and the symlinks will be followed. I haven't looked at the actual code for this part, but there is one line in this page http://www.tug.org/texinfohtml/kpathsea.html#Subdirectory-expansion reading "You can disable the trick by undefining UNIX_ST_LINK in kpathsea/config.h. (It is undefined by default except under Unix.)" So I guess the quick fix is to disable UNIX_ST_LINK on Fedora Core. However, if the search performance is the main concern, the code for kpathsea has to be modified. I don't have a solution. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. See the description Additional info:
I'm not sure whether the undefinition of UNIX_ST_LINK will help somehow as I grepped all teTeX sources, including kpathsea and found no checks or definitions of this macro in teTeX-3.0 and teTeX-2.0.2 at all. I found the UNIX_ST_LINK macro is only noted in the documentation...
Ok, closing NOTABUG, because of teh reason in comment #1.
