Hi all,
Today I ran into a problem that my IDL just could not find my online
help files. I tried to set the '!help_path' by several ways, e.g.
Pref_Set in my start_up file, or 'setenv' in the .cshrc file, then I
checked it by ' print, pref_get('idl_help_path')', and everything
turned out perfect as I set. BUT....everytime I tried to activate my
help in IDL by e.g. ’?mean‘, it said: The page could not be found! '/
usr/local/idl64/help
/online_help/MEAN.html' . This is a directory that does not exist at
all! I am sure I never set that directory as the !help_path. It is not
the same as the default value either, since I was able to see this
default path by 'PRINT, EXPAND_PATH('<IDL_DEFAULT>', /HELP)'. This
default one is exactly the same as what I set in the startup file or
in the .cshrc file : '/opt/idl/idl64/help:/opt/idl/idl64/help/
online_help', and I can see all the documents in the
subdirectories... ...
Can someone help me out here? I read a lot of previous posts and seems
that even Dr. David Fanning has encountered some problem with path
setting in IDL, although his case seems more complex than mine.. Am I
doing something stupid here or any of you have found the same issue
before? It is not a major problem, but it is just frustrating to have
it in your work... Really want to figure it out.
Look forward to your ideas and discussions.
