Please let me know if you need to see any of my log >files or if you have any questions. Immediately I see a reference to 'killall' which I assume is a reference to the LDM utility 'hupsyslog'. There are a number of issues here: - killall should be run from hupsyslog _only_ on SGI systems; all others support direct use of 'kill' to send a signal to a process - if your Solaris installation is trying to use 'killall' it means that you had some environment variables set that you shouldn't have before you ran the 'configure' script that creates the LDM make files. You should _not_ have the following environment variables defined before running 'configure': CC CFLAGS CPPFLAGS LDFLAGS LIBS On SGI, 'killall' is used to send a signal to a process using its name. 'hupsyslog' uses 'kill' to send a HUP signal to syslogd so that syslogd will close the open file descriptor to the LDM log file so that the log file can be 'rotated' (renamed and a new one created in its place). re: "If this is an LDM bug, it's a bad bug. Because if 'killall' did work for you, it would have all but turned amrc off." This is not an LDM bug, it is a user error the solution for which is get one's environment setup correctly before attempting an LDM build. So, what you need to do is the following: <logon as 'ldm'> ldmadmin stop <- stop the LDM if it is running -- examine your enviornment to see what environment variables you have defined: env -- unset all environment variables that would be used by 'configure' cd ldm-6.3.0/src make distclean ./configure make make install su make install_setuids exit That should be it. If you need help figuring out what to undefine, please send me the output of 'env'.
