gdb 4.17 on solaris 8/intel

[Dave Denholm]

Hi,
   not sure if this counts as a bug report or just some feedback,
or I just didn't read all the release notes properly (at all ?)

gdb 4.7 on i386-pc-solaris2.8

config.status contains :

#!/bin/sh
# This file was generated automatically by configure.  Do not edit.
# This directory was configured as follows:
./configure --host=i386-pc-solaris2.8 --norecursion 
# using "mh-frag"



I was finding that when starting gdb on a threaded program, it said

$ gdb.orig gen/BIN/evmDb
[GDB will not be able to debug user-mode threads: ld.so.1: gdb.orig: fatal: relo
cation error: file /usr/lib/libthread_db.so.1: symbol ps_pstop: referenced symbo
l not found]

This GDB was configured as "i386-pc-solaris2.8"...


A little poking around / reading of sol-thread.c reveals that ps_pstop
is a symbol exported from gdb for libthread_db.so to call.

But it didn't seem to be exported (nm -D, etc)

relinking with gcc -Wl,-E  (export all symbols) seemed to fix the
problem for me - presumably this is overkill, and just exporting the ps_
functions would suffice, but I just wanted to get on...


Built using gcc 2.95.2, which was configured --with-gnu-as --with-gnu-ld
(not sure if you need to know that...)


Hope this is useful - please write back if there's anything else you need to
know.

thanks
