Yes.

KC: is there a way/plan to make the relative path. Please note this is
the whole purpose of this mail. The following is just an example to
illustrate the problem I am facing.

what is \\host1 ?

KC: you can think \\host1 is a mount point. For example, suppose my code
is under /homes/xcai/code/, and this directory is in the local disk of
machine \\host1. This directory is also exported as an NFS file system.
So on another machine host2, this directory maybe
/host1/homes/xcai/code. I build the tags on host1 under
/homes/xcai/code, hoping that the IDs will be generated using the
relative path, so that when I cd to /host2/home/xcai/code on host2, I
can run gid also. However, it reported something like this:

lid: can't open `/homes/xcai/code/igmp/igmp.h': No such file or
directory

Could you state your idutils version, your OS and
architecture of the hosts involved and a clear
description of which commands you run, and what you
get instead?

KC: lid - 4.2; FreeBSD 4.11;
Having code in host1 under /homes/xcai/igmp/igmp.h, which has igmp_init
as an ID;
On host1, under /homes/xcai, "mkid *", which generates file ID under
this directory;
On host1, under /homes/xcai, "gid igmp_init" shows line numbers in file
igmp/igmp.h;
On host2, under /host1/homes/xcai, "gid igmp_init" shows error:
lid: can't open `/homes/xcai/igmp/igmp.h': No such file or directory

Would like to see gid works on host2 in this case without build another
copy of ID. Thanks.


Thanks,

Claudio
