Re: GDB bug: target.c (target_signal_from_host): unrecognized real -time signal on arm

Re: GDB bug: target.c (target_signal_from_host): unrecognized real -time signal on arm

[todd.kallam]

Hi,

I have had the same problem with each of the following versions:

   insight+dejagnu-5.2.0_20020624.tar.bz2
   gdb+dejagnu-weekly-CVS-5.2.0_20020618.tar.bz2
   gdb-5.2.tar.gz

I configure gdb with the following command:

     ./configure --target=arm-linux

I configured gdbserver with the following command:

   ./configure arm-linux

The following insight+dejagnu-5.2.0_20020624.tar.bz2 code in
gdb/signals/signals.c reports the problem:

#if defined (SIGRTMIN)
  if (hostsig >= SIGRTMIN && hostsig <= SIGRTMAX)
    {
      /* This block of TARGET_SIGNAL_REALTIME value is in order.  */
      if (33 <= hostsig && hostsig <= 63)
     return (enum target_signal)
       (hostsig - 33 + (int) TARGET_SIGNAL_REALTIME_33);
      else if (hostsig == 64)
     return TARGET_SIGNAL_REALTIME_64;
      else
     error ("GDB bug: target.c (target_signal_from_host): unrecognized real-time
 signal");
    }
#endif

Regards,

Todd

I committed a fix for this problem at the same time I committed the
multithread support.  Could you be more specific about which snapshot
you are using?

You're using snapshots from the 5.2 branch.  You need to look for
snapshots from the trunk if you want to debug an application using
threads or realtime signals.  Get snapshots from current/ insteaad of
from branch/.

Hi,

Thanks for the help.  I am now using insight+dejagnu-20020625.tar.bz2 from
the current directory and it is working.

Regards,

Todd

GDB bug: target.c (target_signal_from_host): unrecognized real -time signal on arm

[todd.kallam]

Hi,

I am trying to use the latest snapshot of gdb to do remote debugging
of a multithreaded Qt application on a strongarm processor running
linux.  I get the following message shown by gdbserver on the target:

GDB bug: target.c (target_signal_from_host): unrecognized real-time signal

The hostsig value is 32, but this value is not handled by the code.

Has any one else had this problem?

I am using gcc 2.95.3 for arm-linux and kernel version 2.4.18 with arm patches.
Thanks for any help.

Regards,

Todd
