WSL2 Ubuntu package failure

Unfortunately, I don't have a Windows machine with WSL2 available.

/mnt/c/Dev/Couloir/Research/aws/aws-lambda-cpp/build/packager: Command not found
Can you verify that the file exists and is executable?
Can you run it manually?

[VikingExplorer]

What would the exact command be? There is no packager folder. gunnar@Aspen:/mnt/c/Dev/Couloir/Research/aws/HelloCMake/build$ ls CMakeCache.txt CMakeFiles Makefile cmake_install.cmake compile_commands.json demo gunnar@Aspen:/mnt/c/Dev/Couloir/Research/aws/HelloCMake/build$ make aws-lambda-package-demo [100%] Built target demo make[3]: /mnt/c/Dev/Couloir/Research/aws/aws-lambda-cpp/build/packager: Command not found

[marcomagdy]

OK - I now see that the packager path is wrong.
It should be coming from your install directory ~/lambda-install instead.
This could be a CMake quirk (which version are you using?)

[VikingExplorer]

cmake version 3.16.3
So, what do I need to change to make this work?

[marcomagdy]

I don't have a good solution for WSL2 (for reasons mentioned earlier).
I would try to either build on Linux (virtual) machine or build on a docker image of Ubuntu.

[VikingExplorer]

I'm just working on a POC. I've already uploaded a zip file for a Python lambda. I've started the process to create a linux hyper-v machine, but it seems like intrusive overkill. There must be a simpler way.

All I need to to is build a single CPP file, link & create a zip file that includes the aws runtime. I'm looking through CMake, which seems like a giant ill-conceived preprocessor for make. I can't find the command to zip up files. I'd love to be able to run a few commands to build & zip. It shouldn't be that hard. Any help would be greatly appreciated.

[marcomagdy]

You can run packaging/package <binary filename>.

[VikingExplorer]

Success. After installing zip, this worked:

../../aws-lambda-cpp/packaging/packager demo

Funny (or maybe not) that I replaced a single CLI cmd with another single command.

Anyways, thanks for all your help.
