I recently installed Solaris 8 on a Pentium machine and tried to use gcc 2.95.2 and gdb 4.18 as they were set up by the default installation process. gcc runs fine, but gdb insists that it can't access the /proc files for whatever program I try to debug. The programs I've tried run fine from the command line, it's just gdb that can't run them. I've tried "debugging" system commands (e.g. echo) as well as programs I compiled myself. I've tried from root as well as from other userids. I've tried letting gdb start the program and I've tried connecting gdb to an existing process. I've tried different shells. I downloaded a fresh copy of gdb-4.18 source and rebuilt gdb (ran "configure" with no options). I tried rebuilding gdb as root and as other userids. I get the same type of error under all conditions (see below) except that when I'm root I get "/proc/7656/ctl: Inappropriate ioctl for device" while when I'm some other user I get "/proc/7656/ctl: Permission denied". I thought of trying to change the default permissions for the /proc directory, but the system wouldn't allow that (wisely no doubt!). Does anyone know of any system settings that might be causing this or has something changed in Solaris 8 that gdb isn't handling? I'm new to UNIX, new to GNU tools, and fresh out of ideas. I'll appreciate any help anyone can offer! ------------------------------------------------------------------------------ GNU gdb 4.18 Copyright 1998 Free Software Foundation, Inc.
