postinstall script problem

[Jun Zhang_4]

In the postinstall script executed by swinstall, the command
perl Makefile.PL
generated Makefile. The variable PERL is assigned the value "0" in the Makefile, which caused the execution phase of swinstall to fail. The error message in /var/adm/sw/swagent.log is "perl is not found".
If "perl Makefile.PL" is executed manually, the PERL variable in Makefile has a value /opt/perl/bin/perl as expected.
I added
echo $PATH > /tmp/result
ll /opt/perl/bin/perl >> /tmp/result
in the postinstall script before the line
perl Makefile.PL
and run swinstall, the result is fine.
Can somebody help?

Within the sw session our usual PATH variable does not exist or will not work, I am not sure of which one...Many of the sw install scripts will get executed even before the PATH is set. Hence in all our sw scripts(configure, postinstall, preinstall and so on), we are expected to give the full paths. I guess the only path they can recognise is the /sbin.

Just try giving the whole path of perl within the sw script and then try the same.

Or set your PATH variable in the post install script. When editing the file using vi type:
!!env | grep ^PATH=

It will put your current PATH in the file.
Same works for other variables too, of course.
