Fletch is on the right track with this. First, everything you do with clearcase inside some view tag has to be 'exec'd out'.
So here is one complex way of getting around clearcase problem:
Have perl generate a simple 3 liner sh script, something like,


#!/bin/sh
/pathtocleartool/cleartool setcs -tag VIEWNAME CONFIGSPECPATH
...do things here...

Then, in your perl script, /cleartoolpath/cleartool setview -exec $shellscriptname VIEWNAME

This spawns a new process for each thing you do using clearcase exec, which is the documentation you need to look through.

Hi, Actually I need to completely do it from the windows side. If I understood you right I can't do it using the method suggested.correct me If I am wrong? Thanks

I often find it helpful to print the string out, debug-style, and try executing it manually. Sometimes, just seeing it, the problem pops right out. E.g.

my $cmd = "cd /$view_tag/lib_engine/hwt ; cleartool lsco -cview -r -s 
+ > /$view_tag/lib_engine/hwt/co_file";
warn "cmd:\n$cmd\n"; # what exactly are we going to try to execute?
system $cmd;

my $view_tag = $ENV{'VIEW_TAG'};
system("cd /$view_tag/lib_engine/hwt ;

What's your viewroot?
If you're using view extended pathnames then your views will be visible under (typically) /view/$VIEW_TAG rather than /$VIEW_TAG

Yes. That was the problem. I was using /$view_tag instead of $view_tag. Thanks a lot guys..I got it to work
