It doesn't alway appear, so it has me pretty confused.... sh-2.05b# cat /proc/version Linux version 2.4.21-rc1 (pbarada@hyper) (gcc version 3.3.1) #21 Tue Sep 9 15:43 sh-2.05b# gdbserver2 :3001 /usr/local/bin/page.strip -m16m -J < /dev/lp0 Process /usr/local/bin/page.strip created; pid = 35 Remote debugging from host 10.1.1.2 gdb: error initializing thread_db library. I modified gdbserver/thread-db.c::thread_db_init to print the value of the err that is returned form td_ta_new, and the result is 0x16 which if I read glibc-2.3.2/linuxthreads_db/thread_db.h correctly, the 0x16 returned from td_ta_new() is TD_VERSION which means the version of libpthread doesn't match the version of libthread_db. If I look in gdb for the type of TD_VERSION I don't see TD_VERSION even thos I see it in linuxthreads_db/thread_db.h: (gdb) ptype TD_OK type = enum {TD_OK, TD_ERR, TD_NOTHR, TD_NOSV, TD_NOLWP, TD_BADPH, TD_BADTH, TD_BADSH, TD_BADTA, TD_BADKEY, TD_NOMSG, TD_NOFPREGS, TD_NOLIBTHREAD, TD_NOEVENT, TD_NOCAPAB, TD_DBERR, TD_NOAPLIC, TD_NOTSD, TD_MALLOC, TD_PARTIALREG, TD_NOXREGS} (gdb) ptype TD_VERSION No symbol "TD_VERSION" in current context. My question is how I can tell why gdbserver believes that the verion of libpthread.so.0 doesn't match the version of libthread_db.so.1? Whath options to readelf do I need? execution doesn't work after this (i.e. 'inf thr' doesn't show me my thread, etc). I'm wondering if there's a deeper problem... -- Peter Barada Peter.Barada@motorola.com Wizard 781-852-2768 (direct) WaveMark Solutions(A Motorola Company) 781-270-0193 (fax)
