Port maintainer has been notified. nm will give a useful symbol table on an unstripped libxxx.so, as will readelf -s, as Rafael kindly pointed out. Hadn't noticed that readelf thing before. No man page. Hmmm. Smells gnuish... Yeah, there's an info readelf for those curious about it. Thanks to all! Dave -- Resistance is futile. You've already been GPLed.

On an unstripped .so, nm works fine. Will a stripped .so even work as a library for ld? The one in question seems not to. Dave

If this were an old-style library (i.e. an archive), say libfoo.a, I would use nm. Surely there is a tool for doing this with the .so's. What is it? (it's not strings ;-) The .a library is not available. Uh, you didn't simply try 'nm' and notice that it works on shared objects? If you're looking for something that can see some of the other structure of a shared library, take a look at 'objdump'. Philip Guenther

Thanks for reminding me of objdump; that works, too. (Although it won't show a symbol table (-s) on a stripped .so. -T will show the dynmaic sym.tab. however, stripped or not). I am simply interested in knowing in which library of several possibilities a certain symbol might be defined. Objdump and readelf will do it. thanks to all who responded! Dave
