perl 5.6.1 not installed - why?

[Gerard McNeill]

Hi,

I have installed perl version 5.6.1 via swinstall, there was no problems and i thought it was installed correctly, however when i perform a perl v - get the perl version 4.0 appearing.

Any ideas why this may be happening??

Hi,

Do you have your path set correctly? It sounds like you are picking up the old Perl that comes in /usr/contrib/bin/perl. When I installed Perl 5.6.1 from the depot package, it put it into /opt/perl5/bin. I made a symlink for /usr/bin/perl to point to /opt/perl5/bin/perl.

John,

Tried the following but still no joy -


$ symlink() /usr/bin/perl /application/opt/perl/binperl5.6.1

$ perl -v

This is perl, version 4.0

Hi Gerard,

Use this command
ln -s /usr/bin/perl /application/opt/perl/binperl5.6.1

Rgds,
Jeff

As John said, did you do a "echo $PATH" and did you see if /usr/contrib/bin was in it.

You can also type "whence perl" under ksh and it will tell you which binary it will run.

Hi

Still no joy. Here is what i am doing - any other ideas?

# echo $PATH
/usr/local/bin/gcc:/opt/binutils/bin:/opt/byacc/bin:/var/adm/sw/products/gcc:/us
r/local/bin:/var/adm/sw/products/byacc/pfiles:/usr/sbin:/usr/bin:/usr/ccs/bin:/u
sr/contrib/bin:/opt/nettladm/bin:/opt/fc/bin:/opt/fcms/bin:/opt/upgrade/bin:/opt
/pd/bin:/usr/bin/X11:/usr/contrib/bin/X11:/opt/resmon/bin:/usr/sbin/diag/contrib
:/opt/hparray/bin:/opt/ignite/bin:/sbin:/home/root

As you can see from above /usr/contrib/bin is there..

# ln -s /usr/bin/perl /application/opt/perl/bin/perl5.6.1
ln: /application/opt/perl/bin/perl5.6.1 exists
# perl -v

This is perl, version 4.0

What does the results of "whence" show?

[Gerard McNeill]

# whence perl
/usr/contrib/bin/perl

Hi (again) Gerard,

Man, I'm a real idiot today - must have a dyslexic brain-thing going.
Had that backwards - NEEDS to be

ln -s /application/opt/perl/binperl5.6.1 /usr/bin/perl

Sorry,
Jeff

[Rodney Hills]

I think your ln command is backwards.

ln -s /application/opt/perl/bin/perl5.6.1 /usr/bin/perl

Will make /usr/bin/perl run perl5.6.1

But verify you haven't wiped out perl5.6.1, enter-
/application/opt/perl/bin/perl5.6.1 -v
and see what version. You may have overwritten it and put a symbolic link in its place. In which case you might have to swinstall again.
