Re: [IBMiOSS] gmake: *** virtual memory exhausted. Stop.

Since I am installing Group PTFs (aka waiting...) I will digress through
some of this and you can ask further questions.

First, what was Kevin Turner trying to accomplish? He wanted to install a
Node Package Module (npm) named hiredis(n1) so he could communicate from
Node.js to Redis, which is a NoSQL database that can run on IBM i (thanks
perzl). The "npm install hiredis" command Kevin was running is how you
install packages from the internet. This particular package has a "native"
component. When you see "native" that usually means the language
(Node.js/Ruby/PHP/Python) wasn't fast enough to do something (in this case
a faster parser, though I don't know what it's parsing; maybe JSON?) or it
wasn't worth rewriting something that already exists (i.e. encryption
algorithms). Because it had a native component (C/C++) it required a
compile. This necessitated a bunch more tools, like GNU Make and GCC. GNU
Make (gmake for short) is a tool that looks at a file named "Makefile" that
has instructions on how to create/make the project (like how we might put
together a CL program full of CRTRPGMOD and CRTSRVPGM commands). In
Kevin's scenario gmake was puking because it didn't like ~something~.
Well, we don't necessarily know what that something was in this case. What
we learned is we should ~never~ use QSH or QP2TERM for anything. We should
always STRTCPSVR *SSHD and ssh into the machine into a bash shell (which
IBM now ships with 5733OPS).

Hope that helps.

I on the other agree fully with Tony _except_ I would replace “C” with
“Unixese” - I do know some C but have rarely found it necessary to
utilizing OS software. However the fact that everything is described in
assorted sub-dialects of Unixese _is_ a major inhibitor.

I try to follow some of the conversations on this list and frankly it is
putting me off trying a lot of the stuff. Take an extract from one of the
recent discussions on this list:

"OK thanks all - a little progress. I was now able to install ibm_db from
npm. However, node-gyp rebuild still fails for things like "hiredis". With
that gmake fails:

gmake: *** virtual memory exhausted. Stop.”

I guess it is English of sorts - but where the heck is one supposed to
start ?

Personally I’d like to see IBM make a lot more effort to make this stuff
comprehensible.
