Hi, I wonder why the libpopt.vers version script exports _init and _fini symbols?
Not so much exports the symbols as permits exposure.
Dynamic linker calls _init/_fini anyway. Regular application can use these symbols only via dlsym(3).
The likeliest reason is that gnutls (which I used as a model for drilling loader maps into rpm/popt) exported the symbols several years ago, and its seemed like a good idea. No other reason I remember. I'm more interested in tracking the symbols in the ABI, and preventing accidental leakage of other symbols in libpopt (and rpm libraries) than anything else. Neither popt (with its POPT_AUTOALIAS table) and similar static arrays exposed in the rpmlib ABI have symbols that qualify as an ABI. 73 de Jeff ______________________________________________________________________ POPT Library http://rpm5.org Developer Communication List popt-devel@rpm5.org
