Google did not reveal anything helpfull. I resently moved to kernel 2.6.0 (on Debian Sarge), and while everything seems to work just fine, to my surprise gdb now fails to debug executables that are linked against pthread: GNU gdb 5.3-debian [snip] This GDB was configured as "i386-linux"... (gdb) b main Breakpoint 1 at 0x80483a4: file foo.c, line 3. (gdb) r Starting program: /root/a.out Error while reading shared library symbols: Cannot find new threads: capability not available Cannot find user-level thread for LWP 714: capability not available With kernel 2.4.22 this problem did not occur. Do you have any idea what may have caused this problem, and how to solve it? If I can provide you with any information that could be helpfull, please let me know. Kind regards, Maarten gcc version 3.3.2 (Debian) GNU gdb 5.3-debian GNU libc 2.3.2
