I'm not sure that that's the answer to the problem. I think to get an answer from the list you'll need to supply a bit more info. If we could see the link command you're using and the options passed to it that may help. There are various options that can specify static only or dynamic only linkage, or that can tell the compiler/linker to ignore ldconfig settings, and we don't know if you may have inadvertantly use one or more of them.
.so files are shared libraries (Shared Object) .a files are static libraries (Archive) neither are used exclusively for development or release and often both are provided - ie you may get both static and shared versions of the same library, be it development or release. Note also that ldconfig -v probably gives you more info than you really need, and will take significant time to complete, when simply checking for library resolution. I generally use ldconfig -p when just checking that the lib is searchable. ty > -----Original Message----- > From: Visser, Martin (Sydney) [mailto:[EMAIL PROTECTED]] > Sent: Thursday, 11 July 2002 17:26 > To: [EMAIL PROTECTED]; [EMAIL PROTECTED] > Subject: RE: [SLUG] finding libraries to link (no subject) > > > Melinda, > > I haven't seen a reply for this yet, so I thought I'd give it a go. > > Not having my linux box up at the mo' but I think you will > find that the .so files are just the "runtime" libraries > dynamically linked.
