The program on the target uses pthreads. I can connect, but as soon as you try to continue (to a breakpoint) I get: Program received signal SIG32, Real-time event 32. warning: Warning: GDB can't find the start of the function at 0x2abee684. .... I know that SIG32 is used for the thread control on the target, but I'm not sure if the host gdb is supposed to receive this. I tried "set handle SIG32 pass noprint nostop" and variations, but this didn't help. Does anyone know whether there is some special setup needed on gdb/gdbserver to use the multi-threaded gdbserver ?? My environment is as follows: CPU: NEC VR5432 kernel: linux-2.4.18 + patches glibc: 2.2.3 + patches gdb: 5.2/3 from CVS gcc: 3.1 binutils: Version 2.11.90.0.25 cross-gdb configured using: configure --prefix=/usr --target=mipsel-linux --disable-sim --disable-tcl --enable-threads --enable-shared gdbserver configured using: configure --prefix=/usr --host=mipsel-linux --target=mipsel-linux --enable-threads --enable-shared Regards, Stuart
