That's on purpose. res_mkquery is in i386 etc. libresolv.so only for compatibility reasons. For newer architectures (e.g. x86_64, s390x or powerpc64) such compatibility is not needed, therefore just __res_mkquery is provided. Ok. What is the proper fix for programs (or configure scripts) that require res_mkquery ? Replacing res_mkquery by __res_mkquery makes it work on 64bit, although I don't think I understand why that is required. Do you have a link to some more information about this (Google wasn't much of a help). Thanks in advance. If you #include <resolv.h>, res_mkquery will be __res_mkquery (it is a #define). Configure tests that test for res_mkquery etc. without #include <resolv.h> are just broken. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20041020 Galeon/1.3.18 Description of problem: The libresolv.so library in the glibc package on x86_64 is missing the res_mkquery symbol which breaks configure scripts on x86_64. This is true for FC3/x86_64, FC2/x86_64 and EL3/x86_64.
