help with gcc-3.2 related bug
Hello,
I have been suggested to ask for help here; please bounce me
somewhere else if I am writing to the wrong address. I got a bug reported on
libsablot0c102 package, which appeared on the migration to gcc-3.2. Do you
recommend adding -lstdc++, or do you have a better advice? Thanks a lot, and
please excuse me if this mail should not be sent to you. Bug report forward
follows.
Kind regards

This bug is related to 179724.
The following undefined references in libsablot.so.0 are provided by
libstdc++:
$ nm -Du /usr/lib/libsablot.so.0.97.0 |grep '_[JZ]'
_Jv_RegisterClasses
_ZTVN10__cxxabiv117__class_type_infoE
_ZTVN10__cxxabiv120__si_class_type_infoE
_ZTVN10__cxxabiv121__vmi_class_type_infoE
_ZdaPv
_ZdlPv
_Znam
_Znwm
However, libsablot.so.0 isn't linked against libstdc++. As a result,
any DSO that links against libsablot.so.0 (such as php4-xslt, and
probably libxml-sablot-perl) is unusable because these undefined symbols
will not be resolvable at load time (i.e., when calling dlopen with
RTLD_NOW).
It appears that sablotron, though written in C++, does not explicitly
*use* libstdc++ for anything, or this problem would have been reported
before. As a result, this might legitimately be considered a toolchain
bug; I recommend consulting the gcc team for advice on how to fix this,
since it clearly was not a problem with gcc 2.9x.
Worst case, you can add -lstdc++ (possibly specifying -static as well)
to the library link list.
