What is interesting is that on our server we don't appear to have the
path
specifically set to anything and yet it works.

I am not certain about this, but IBM's installation might conditionally
create the symlinks --or-- they may have tried to create the symlinks
and
it failed because perzl is part of the default PATH (which if failing on
libcrypto.a).

Node v0.12 (5733-OPS Option 1) used its own install mechanism and with
manual code for creating all the symlinks (yuck). For Python, I wrote a
new install mechanism that just generates a save file that gets restored
with the symlinks. One aspect of this is that if the symlink already
exists, it will not get overwritten during our install. Whether this is
right or wrong is a matter of opinion, but the good news is that Perzl
installs in to /opt/freeware/bin and /usr/bin while PASE/OPS installs to
/QOpenSys/usr/bin, so we should never run in to a conflict unless someone
has created their own link in /QOpenSys/usr/bin.

Also, PATH is not used for symlink creating. The only thing PATH is used
for is when calling execp() (or one of it's variants) to find the path to
the program being executed if you don't specify an absolute or relative
path: https://linux.die.net/man/3/exec

Thanks Aaron

We aren't using v.0.12.x but they were - but I have fixed that.

I will check if they have perzl installed...

Further to Robert's comments, you should also run the
/QOpenSys/QIBM/ProdData/OPS/Node4/bin/nodeenv.sh(n1) shell script
which
will set the symlinks in /QOpenSys/usr/bin.

n1 - More info here: http://bit.ly/developerWorks-node-v4

Concerning why it bombs on libcrypto.a, that many times is because of
a
conflict with perzl stuff. Remove /opt/freeware/bin from PATH and see
if
that allows it to continue. If you need perzl stuff in your path then
that's a longer conversation to fix it.

Also, it appears you're using Node
v.0.12.x(/QOpenSys/QIBM/ProdData/Node/bin/node). IBM has alluded
giving
that an EndOfLife, time to move on to Node
v4.x(/QOpenSys/QIBM/ProdData/
OPS/Node4/bin/node).

I had the same issue. Look inside the OPS for NODE4 and add that
to
the path. It should find node then.

Hi

The guys managing our US IBMi servers are now trying to install
5770OPS.
They have installed the product and all PTFs, but it is still
foobar.

First and foremost no symbolic links have been created in /usr/bin
for
the
“node” and “npm” commands.
Despite that, even if you navigate to
QOpenSys/QIBM/ProdData/Node/bin
and
execute the node command it fails:

node -v
exec(): 0509-036 Cannot load program node because of the following
errors:
0509-150 Dependent module libcrypto.a(libcrypto.so.1)
could
not
be loaded.
0509-022 Cannot load module libcrypto.a(libcrypto.so.1).
0509-026 System error: A file or directory in the path
name
does not exist.

Sounds like something else needs to be there that 5770OPS does not
install
(ssh perhaps)?

I am not sure how or why IBM are making such a pigs ear of this.
Anyone
seen this before?

Thanks
Kevin
