[Bug gdb/11743] New: gdb --pid <pid> does not find file on AIX

[rick dot stein at aciworldwide dot com]

The above command does not work on AIX

--- Test Source ---

~/gdb/test
imts1-AIX(1):steinr> cat take5.c
#define ONE_MINUTE 60
main()
{
int minutes = 5;

while(minutes--)
  sleep(ONE_MINUTE);
}

The above happens on AIX 5.2 and AIX 5.3

I have ported support for COBOL from gdb-5.3 to gdb-6.8.  This port does not 
work on gdb-7.1, so I need the above to work on gdb-6.8.  The above tests were 
run with an unmodified, freshly compiled gdb-6.8.

Note that this works fine on gdb-6.8 running on RedHat Linux

------- Additional Comments From rick dot stein at aciworldwide dot com  2010-08-27 21:02 -------
Traced the issue to the fact that refactoring moved SOLIB_ADD() from
run_command_1() (in 5.3) to post_create_inferior() in infcmd.c:1952 and
conditionalized it on exec_bfd which is always NULL, and thus, skipped the
SOLIB_ADD() call. Not sure if this is the proper fix but it works for me.

Please try mainline cvs and confirm whether the same problem persists there. 
Please attach changes as patches extracted with "cvs diff -up", and without any
unrelated changes to this problem, instead of whole modified source files.

>From the sounds of it, the real solution of this may be for someone motivated to
do the long overdue conversion of xcoffsolib.c to the generic solib.c
mechanisms, and get rid of all the DEPRECATED_IBM6000_TARGET code in exec.c.

Turns out Joel did this for 7.7.  AIX now uses the same mechanisms as all other
ports, so this is most probably fixed in 7.7.  Therefore I'm closing this. 
Please reopen if you still see the same problem.
