I cannot find anything with the >string 'ZN8DwStringixEm' in either kdepim or kdelibs sources. It wouldn't. It is a C++ mangled symbol. Entries in the symbol table must be distinct is name only, but C++ functions do not. Therefore any function with C++ linkage generates a symbol based on more than it's name. >> The new version of the library is no longer exporting its internal >> portability functions.

We cannot know >about custom software though. That's okay (at least for these symbols). They shouldn't have been exported in the first place. Custom software that depends on getting these symbols from mimelib1 is already incorrect, it just happens to work for now. It should be mentioned in the Changelog (or maybe Debian.NEWS; I'm not sure.) >> More concerning is the last symbol removal, which indicates that the >> library has removed: >> >> DwString::operator[](unsigned long) >DwString::operator is defined in mimelib/mimelib/string.h, and no change >was made to that header file at all. 'DwString::operator' isn't defined anywhere. "operator" is a C++ keyword used for operator overloading. It is always followed by some operator punctuation (e.g.: +, -, [], (), =) to indicate which operator is being overloaded. The function in question is 'DwString::operator[]' specifically the overload that takes an 'unsigned long' as an argument (and based on the rules of operator overloading, has to be a member function of DwString.) You diff doesn't show this change, so I'm not exactly sure why the function is no longer exported (or present). -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
