Question about resolving symbol information from so's loaded via dlopen.

Question about resolving symbol information from so's loaded via dlopen.

[Kevin "Sharpie" Endres]

in GDB 5.2.1.

I am attempting to debug using a core from an application that loads an .so
via dlopen using an absolute location. When i target the core in gdb - the
.so's  attempt to load using the absolute path (the core file was not
generated on my machine) and fail. 

How do I work around this?

Thanks in advance.

Probably the best thing to do is to set up a directory tree that looks
like the target machine somewhere, and set solib-absolute-prefix to
point to it.  That is,

/opt/tst/lib/libc.so.6
/opt/tst/lib/ld.so.1
/opt/tst/usr/lib/appname/plugin.so

(gdb) set solib-absolute-prefix /opt/tst
