AWS Lambda Node10.x issue

[dcarrion87]

Just wanted to see if you're looking to fix the Node10.x binding so it works on AWS Lambda? AWS are deprecating 8.10 and your Node10.x bindings do not work on Amazon Linux.

At the moment there's a GLIBC incompatibility:

Error: /lib64/libm.so.6: version `GLIBC_2.27' not found (required by /home/ec2-user/test/node_modules/images/vendor/linux-x64-64/binding.node)

Versions on Lambda:

[ec2-user@amzn2 linux-x64-64]$ yum info glibc | grep Version
Version     : 2.26
Version     : 2.26

Also if you could provide instructions for how you call node-gyp as I'm getting segmentation faults no matter how I compile with 10.x

Oddly if I compile in Debug mode I don't get the segmentation fault!?!?

node-gyp --debug configure rebuild

[dcarrion87]

OK I managed to get around this by adding the following to the binding.gyp to disable compiler optimizations.

'cflags!': [ '-O3']

This is not ideal due to performance impact. What compiler is the maintainer using to build the public releases? Could we get a snapshot of compiler params to see how they compare?

This is a tricky one to debug!
