site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com User-agent: Mutt/1.5.18 (2008-05-17) The gdb developers are rapidly approaching the release of gdb 7.0 (which will be required to debug optimized code generated by gcc 4.5 due changes related to the var tracking association merge and other code). They currently have patches proposed that allows gdb 7.0 to debug code in darwin9.6. However there was some change made in darwin9.8 and darwin10 which no longer allows the previous approach of making gdb belong to the procmod group... sudo chgrp procmod gdb sudo chmod g+s gdb Under darwin9.6 and darwin10 (but not darwin9.5), this results in the error... (gdb) break 4 Breakpoint 1 at 0x10000154c: file himenoBMTxpa.c, line 4. (gdb) r Starting program: /Users/howarth/a.out Unable to find Mach task port for process-id 154: (os/kern) failure (0x5). (please check gdb is setgid procmod) (gdb) Can someone at Apple provide the gdb developers with some advice on what is the new approach recommnded for gdb to have proper permissions and group ownership to function under darwin9.5.8 and darwin10?
