Hmmm, Segmentation Fault 11 with Cloud Foundry

Whilst following this online course: -

LFS132x Introduction to Cloud Foundry and Cloud Native Software Architecture

I was tinkering ( man, I love that word ) with Cloud Foundry ( CF ).

Now it's been a while and I've been through a macOS upgrade from Sierra to High Sierra ( wonder if there's a clue there ? ).

So this time around, I'm seeing "Segmentation Fault: 11" : -

cf version

Segmentation fault: 11

cf login

Segmentation fault: 11

which cf

/usr/local/bin/cf

ls -al `which cf`

-rwxr-xr-x  1 root  wheel  23559164 11 Aug  2016 /usr/local/bin/cf

I tried downloading a new copy of the Bluemix CLI code from here: -

https://github.com/IBM-Bluemix/bluemix-cli-release/releases/tag/v0.6.1

and, having installed the same, tried again, but alas with the same results.

Using this as inspiration: -

Download and install IBM Cloud CLI

I tried this: -

curl -fsSL https://clis.ng.bluemix.net/install/osx | sh

Current platform is macOS. Downloading corresponding Bluemix CLI...

but again to no avail.

So I dug further, and realised that, whilst I was upgrading the Bluemix code, the CF code was staying as-is, as evidenced: -

ls -al `which cf`

-rwxr-xr-x  1 root  wheel  23559164 11 Aug  2016 /usr/local/bin/cf

So, from here: -

The official command line client for Cloud Foundry http://docs.cloudfoundry.org/cf-cli

specifically this: -

curl -L "https://cli.run.pivotal.io/stable?release=macosx64-binary&source=github" | tar -zx

which gave me this: -

-rwxr-xr-x     1 davidhay  staff  18472468  9 Nov 17:08 cf

which JUST WORKS !!

~/cf version

cf version 6.32.0+0191c33d9.2017-09-26

etc.

So, to finish off, all I needed to do was this: -

sudo mv ~/cf /usr/local/bin

and then validate: -

ls -al `which cf`

-rwxr-xr-x  1 davidhay  staff  18472468 26 Sep 22:44 /usr/local/bin/cf

cf version

cf version 6.32.0+0191c33d9.2017-09-26

and we're golden.
