Hello everyone - quick question.
I've been having a very odd problem under BSDI 2.x. Our socks server can
load shared libraries to add new authentication methods, etc, and uses the
dlopen() dlsym() API to do so. This works fine on other OSes (Solaris,
Linux, AIX, IRIX, HP/UX (via shl_load, etc)). BSDI is not cooperating
though.
The dlopen() fails and dlerror() returns:
can't resolve undefined symbols: No such file or directory
This is using an absolute pathname to the shared library to be loaded, so
LD_LIBRARY_PATH isn't needed, etc. I also tried linking in the core C
library to the .so, just in case it was a problem with the .so using
'printf' or some other function that wasn't exported by the parent. No go.
The really odd thing is that it works fine when you run it under GDB. The
module loads and symbols are found, etc. Has anyone else out there run
into something like this under BSDI?
-Bill P.
