[Mageia-dev] On binary version references requirements

[Funda Wang]

Hello,

In /usr/lib/rpm/mageia/find-requires, it reads:

# Weak symbol versions (from glibc).
<snip>
        (START==2) && (LIBNAME!="") && ($4!="") && (($4~/^GLIBC_*/) ||
($4~/^GCC_*/)) {
             print LIBNAME "(" $4 ")'$lib64'";
         }


That means, we only prints those weak symbols regarding GLIBC and GCC. But why?

$ objdump -x /usr/lib64/libwebkitgtk-1.0.so.0

     0x09691974 0x00 02 GLIBC_2.3.4

That means, ABI versions regarding LIBXML2* and LIBJPEG* are not
raised when packaging. Fedora is promoting those extra ABI versions
now. I read history on mandriva's repository, but could not find any
relevant information.

Any thoughts to export those requirements?
