Hi, thanks for the quick response regarding the irritating warning.
My next problem appears while debugging an application on a Blackfin target with gdbserver + gdb. Debugging hangs when the first rt_task_create is reached. Starting in my application: 153 int prio = T_HIPRIO/2; 154 int r = rt_task_create(&thread, thread_name.c_str(), 128*1024, prio, T_FPU|T_JOINABLE); ... Single-stepi'ing the call, gdb loses contact shortly after clone() in http://git.uclibc.org/uClibc/tree/libpthread/linuxthreads.old/pthread.c It looks like this could be related to a manager thread? These are the last lines from gdb (using stepi) 45 in libc/sysdeps/linux/bfin/clone.c 0x00e4cb00 in clone (f...@0xec235c: 0xed5a64 <__pthread_manager_event>, child_stack=0xefb5cc, flags=3840, arg=0x0) at libc/sysdeps/linux/bfin/clone.c:45 45 in libc/sysdeps/linux/bfin/clone.c 0x00ed8734 in __pthread_initialize_manager () at libpthread/linuxthreads.old/pthread.c:600 600 libpthread/linuxthreads.old/pthread.c: No such file or directory. in libpthread/linuxthreads.old/pthread.c 606 in libpthread/linuxthreads.old/pthread.c 0x00ed8738 606 in libpthread/linuxthreads.old/pthread.c 615 in libpthread/linuxthreads.old/pthread.c 614 in libpthread/linuxthreads.old/pthread.c 0x00ed8740 614 in libpthread/linuxthreads.old/pthread.c 616 in libpthread/linuxthreads.old/pthread.c 612 in libpthread/linuxthreads.old/pthread.c 615 in libpthread/linuxthreads.old/pthread.c 616 in libpthread/linuxthreads.old/pthread.c 617 in libpthread/linuxthreads.old/pthread.c 620 in libpthread/linuxthreads.old/pthread.c 0x00ed8754 620 in libpthread/linuxthreads.old/pthread.c 0x00ed4066 in ??

() from /opt/uClinux-2010R1-RC5_tools-RC4/bfin-linux-uclibc/bfin-linux-uclibc/runtime/lib/libpthread.so.0 I need to find out how to prepare the uClibc source so that gdb can find it for further details. But maybe someone yet has an idea about a possible cause (and remedy)?
