hi, While playing a bit with the dlmopen (this is the stock glibc coming with a FC5 system) function, it occured to me that gdb 6.6 does not seem to be able to deal with code loaded in a process through this function. The attached test program shows that, indeed an extra binary is loaded in my process address space but gdb seems unable to place a breakpoint in any of the functions defined in this binary (something like "b gtk_window_new"). So, I tried to figure out how I could fix this in gdb: a bit of debugging shows that gdb is notified of dlmopen calls through the r_debug structure since "set stop-on-solib-events 1" triggers correctly an event upon dlmopen. The question then is why gdb does not add the new binary to its map. Maybe someone more knowledgeable than me about the layout of the gdb code source could point me to the piece of code which updates and manipulates the gdb map of binaries used during symbol lookup ? (I am using an x86 linux system) I apologize before hand if this email is off-topic, regards, Mathieu --
